future, but this is a theoretical limit as the computation of that year
would take too long with the current implementation of adodb_mktime().
This library replaces native functions as follows:
getdate() with adodb_getdate()
date() with adodb_date()
gmdate() with adodb_gmdate()
mktime() with adodb_mktime()
gmmktime() with adodb_gmmktime()
strftime() with adodb_strftime()
strftime() with adodb_gmstrftime()
The parameters are identical, except that adodb_date() accepts a subset
of date()'s field formats. Mktime() will convert from local time to GMT,
and date() will convert from GMT to local time, but daylight savings is
not handled currently.
This library is independant of the rest of ADOdb, and can be used
as standalone code.
PERFORMANCE
For high speed, this library uses the native date functions where
possible, and only switches to PHP code when the dates fall outside
the 32-bit signed integer range.
GREGORIAN CORRECTION
Pope Gregory shortened October of A.D. 1582 by ten days. Thursday,
October 4, 1582 (Julian) was followed immediately by Friday, October 15,
1582 (Gregorian).
Since 0.06, we handle this correctly, so:
adodb_mktime(0,0,0,10,15,1582) - adodb_mktime(0,0,0,10,4,1582)
== 24 * 3600 (1 day)

FUNCTION DESCRIPTIONS
** FUNCTION adodb_getdate($date=false)
Returns an array containing date information, as getdate(), but supports
dates greater than 1901 to 2038. The local date/time format is derived from a
heuristic the first time adodb_getdate is called.
** FUNCTION adodb_date($fmt, $timestamp = false)
Convert a timestamp to a formatted local date. If $timestamp is not defined, the
current timestamp is used. Unlike the function date(), it supports dates
outside the 1901 to 2038 range.
The format fields that adodb_date supports:
a - "am" or "pm"
A - "AM" or "PM"
d - day of the month, 2 digits with leading zeros; i.e. "01" to "31"
D - day of the week, textual, 3 letters; e.g. "Fri"
F - month, textual, long; e.g. "January"
g - hour, 12-hour format without leading zeros; i.e. "1" to "12"
G - hour, 24-hour format without leading zeros; i.e. "0" to "23"
h - hour, 12-hour format; i.e. "01" to "12"
H - hour, 24-hour format; i.e. "00" to "23"
i - minutes; i.e. "00" to "59"
j - day of the month without leading zeros; i.e. "1" to "31"
l (lowercase 'L') - day of the week, textual, long; e.g. "Friday"
L - boolean for whether it is a leap year; i.e. "0" or "1"
m - month; i.e. "01" to "12"
M - month, textual, 3 letters; e.g. "Jan"
n - month without leading zeros; i.e. "1" to "12"
O - Difference to Greenwich time in hours; e.g. "+0200"
Q - Quarter, as in 1, 2, 3, 4
r - RFC 2822 formatted date; e.g. "Thu, 21 Dec 2000 16:01:07 +0200"
s - seconds; i.e. "00" to "59"
S - English ordinal suffix for the day of the month, 2 characters;
i.e. "st", "nd", "rd" or "th"
t - number of days in the given month; i.e. "28" to "31"
T - Timezone setting of this machine; e.g. "EST" or "MDT"
U - seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)
w - day of the week, numeric, i.e. "0" (Sunday) to "6" (Saturday)
Y - year, 4 digits; e.g. "1999"
y - year, 2 digits; e.g. "99"
z - day of the year; i.e. "0" to "365"
Z - timezone offset in seconds (i.e. "-43200" to "43200").
The offset for timezones west of UTC is always negative,
and for those east of UTC is always positive.
Unsupported:
B - Swatch Internet time
I (capital i) - "1" if Daylight Savings Time, "0" otherwise.
W - ISO-8601 week number of year, weeks starting on Monday
** FUNCTION adodb_date2($fmt, $isoDateString = false)
Same as adodb_date, but 2nd parameter accepts iso date, eg.
adodb_date2('d-M-Y H:i','2003-12-25 13:01:34');
** FUNCTION adodb_gmdate($fmt, $timestamp = false)
Convert a timestamp to a formatted GMT date. If $timestamp is not defined, the
current timestamp is used. Unlike the function date(), it supports dates
outside the 1901 to 2038 range.
** FUNCTION adodb_mktime($hr, $min, $sec[, $month, $day, $year])
Converts a local date to a unix timestamp. Unlike the function mktime(), it supports
dates outside the 1901 to 2038 range. All parameters are optional.
** FUNCTION adodb_gmmktime($hr, $min, $sec [, $month, $day, $year])
Converts a gmt date to a unix timestamp. Unlike the function gmmktime(), it supports
dates outside the 1901 to 2038 range. Differs from gmmktime() in that all parameters
are currently compulsory.
** FUNCTION adodb_gmstrftime($fmt, $timestamp = false)
Convert a timestamp to a formatted GMT date.
** FUNCTION adodb_strftime($fmt, $timestamp = false)
Convert a timestamp to a formatted local date. Internally converts $fmt into
adodb_date format, then echo result.
For best results, you can define the local date format yourself. Define a global
variable $ADODB_DATE_LOCALE which is an array, 1st element is date format using
adodb_date syntax, and 2nd element is the time format, also in adodb_date syntax.
eg. $ADODB_DATE_LOCALE = array('d/m/Y','H:i:s');
Supported format codes:
%a - abbreviated weekday name according to the current locale
%A - full weekday name according to the current locale
%b - abbreviated month name according to the current locale
%B - full month name according to the current locale
%c - preferred date and time representation for the current locale
%d - day of the month as a decimal number (range 01 to 31)
%D - same as %m/%d/%y
%e - day of the month as a decimal number, a single digit is preceded by a space (range ' 1' to '31')
%h - same as %b
%H - hour as a decimal number using a 24-hour clock (range 00 to 23)
%I - hour as a decimal number using a 12-hour clock (range 01 to 12)
%m - month as a decimal number (range 01 to 12)
%M - minute as a decimal number
%n - newline character
%p - either `am' or `pm' according to the given time value, or the corresponding strings for the current locale
%r - time in a.m. and p.m. notation
%R - time in 24 hour notation
%S - second as a decimal number
%t - tab character
%T - current time, equal to %H:%M:%S
%x - preferred date representation for the current locale without the time
%X - preferred time representation for the current locale without the date
%y - year as a decimal number without a century (range 00 to 99)
%Y - year as a decimal number including the century
%Z - time zone or name or abbreviation
%% - a literal `%' character
Unsupported codes:
%C - century number (the year divided by 100 and truncated to an integer, range 00 to 99)
%g - like %G, but without the century.
%G - The 4-digit year corresponding to the ISO week number (see %V).
This has the same format and value as %Y, except that if the ISO week number belongs
to the previous or next year, that year is used instead.
%j - day of the year as a decimal number (range 001 to 366)
%u - weekday as a decimal number [1,7], with 1 representing Monday
%U - week number of the current year as a decimal number, starting
with the first Sunday as the first day of the first week
%V - The ISO 8601:1988 week number of the current year as a decimal number,
range 01 to 53, where week 1 is the first week that has at least 4 days in the
current year, and with Monday as the first day of the week. (Use %G or %g for
the year component that corresponds to the week number for the specified timestamp.)
%w - day of the week as a decimal, Sunday being 0
%W - week number of the current year as a decimal number, starting with the
first Monday as the first day of the first week
=============================================================================
NOTES
Useful url for generating test timestamps:
http://www.4webhelp.net/us/timestamp.php
Possible future optimizations include
a. Using an algorithm similar to Plauger's in "The Standard C Library"
(page 428, xttotm.c _Ttotm() function). Plauger's algorithm will not
work outside 32-bit signed range, so i decided not to implement it.
b. Implement daylight savings, which looks awfully complicated, see
http://webexhibits.org/daylightsaving/
CHANGELOG
- 10 Jan 2008 0.31
* Now adodb_mktime(0,0,0,24,1,2037) works correctly.
- 15 July 2007 0.30
Added PHP 5.2.0 compatability fixes.
* gmtime behaviour for 1970 has changed. We use the actual date if it is between 1970 to 2038 to get the
* timezone, otherwise we use the current year as the baseline to retrieve the timezone.
* Also the timezone's in php 5.2.* support historical data better, eg. if timezone today was +8, but
in 1970 it was +7:30, then php 5.2 return +7:30, while this library will use +8.
*
- 19 March 2006 0.24
Changed strftime() locale detection, because some locales prepend the day of week to the date when %c is used.
- 10 Feb 2006 0.23
PHP5 compat: when we detect PHP5, the RFC2822 format for gmt 0000hrs is changed from -0000 to +0000.
In PHP4, we will still use -0000 for 100% compat with PHP4.
- 08 Sept 2005 0.22
In adodb_date2(), $is_gmt not supported properly. Fixed.
- 18 July 2005 0.21
In PHP 4.3.11, the 'r' format has changed. Leading 0 in day is added. Changed for compat.
Added support for negative months in adodb_mktime().
- 24 Feb 2005 0.20
Added limited strftime/gmstrftime support. x10 improvement in performance of adodb_date().
- 21 Dec 2004 0.17
In adodb_getdate(), the timestamp was accidentally converted to gmt when $is_gmt is false.
Also adodb_mktime(0,0,0) did not work properly. Both fixed thx Mauro.
- 17 Nov 2004 0.16
Removed intval typecast in adodb_mktime() for secs, allowing:
adodb_mktime(0,0,0 + 2236672153,1,1,1934);
Suggested by Ryan.
- 18 July 2004 0.15
All params in adodb_mktime were formerly compulsory. Now only the hour, min, secs is compulsory.
This brings it more in line with mktime (still not identical).
- 23 June 2004 0.14
Allow you to define your own daylights savings function, adodb_daylight_sv.
If the function is defined (somewhere in an include), then you can correct for daylights savings.
In this example, we apply daylights savings in June or July, adding one hour. This is extremely
unrealistic as it does not take into account time-zone, geographic location, current year.
function adodb_daylight_sv(&$arr, $is_gmt)
{
if ($is_gmt) return;
$m = $arr['mon'];
if ($m == 6 || $m == 7) $arr['hours'] += 1;
}
This is only called by adodb_date() and not by adodb_mktime().
The format of $arr is
Array (
[seconds] => 0
[minutes] => 0
[hours] => 0
[mday] => 1 # day of month, eg 1st day of the month
[mon] => 2 # month (eg. Feb)
[year] => 2102
[yday] => 31 # days in current year
[leap] => # true if leap year
[ndays] => 28 # no of days in current month
)
- 28 Apr 2004 0.13
Fixed adodb_date to properly support $is_gmt. Thx to Dimitar Angelov.
- 20 Mar 2004 0.12
Fixed month calculation error in adodb_date. 2102-June-01 appeared as 2102-May-32.
- 26 Oct 2003 0.11
Because of daylight savings problems (some systems apply daylight savings to
January!!!), changed adodb_get_gmt_diff() to ignore daylight savings.
- 9 Aug 2003 0.10
Fixed bug with dates after 2038.
See http://phplens.com/lens/lensforum/msgs.php?id=6980
- 1 July 2003 0.09
Added support for Q (Quarter).
Added adodb_date2(), which accepts ISO date in 2nd param
- 3 March 2003 0.08
Added support for 'S' adodb_date() format char. Added constant ADODB_ALLOW_NEGATIVE_TS
if you want PHP to handle negative timestamps between 1901 to 1969.
- 27 Feb 2003 0.07
All negative numbers handled by adodb now because of RH 7.3+ problems.
See http://bugs.php.net/bug.php?id=20048&edit=2
- 4 Feb 2003 0.06
Fixed a typo, 1852 changed to 1582! This means that pre-1852 dates
are now correctly handled.
- 29 Jan 2003 0.05
Leap year checking differs under Julian calendar (pre 1582). Also
leap year code optimized by checking for most common case first.
We also handle month overflow correctly in mktime (eg month set to 13).
Day overflow for less than one month's days is supported.
- 28 Jan 2003 0.04
Gregorian correction handled. In PHP5, we might throw an error if
mktime uses invalid dates around 5-14 Oct 1582. Released with ADOdb 3.10.
Added limbo 5-14 Oct 1582 check, when we set to 15 Oct 1582.
- 27 Jan 2003 0.03
Fixed some more month problems due to gmt issues. Added constant ADODB_DATE_VERSION.
Fixed calculation of days since start of year for <1970.
- 27 Jan 2003 0.02
Changed _adodb_getdate() to inline leap year checking for better performance.
Fixed problem with time-zones west of GMT +0000.
- 24 Jan 2003 0.01
First implementation.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library.
We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library.
In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things:
a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place.
e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

(c) 2000-2004 John Lim (jlim@natsoft.com.my)
Released under both BSD and GNU Lesser GPL library license.
This means you can use it in proprietary products.
>> Introduction
PHP's database access functions are not standardised. This creates a
need for a database class library to hide the differences between the
different databases (encapsulate the differences) so we can easily
switch databases.
We currently support MySQL, Interbase, Sybase, PostgreSQL, Oracle,
Microsoft SQL server, Foxpro ODBC, Access ODBC, Informix, DB2,
Sybase SQL Anywhere, generic ODBC and Microsoft's ADO.
We hope more people will contribute drivers to support other databases.
>> Documentation and Examples
Refer to the adodb/docs directory for full documentation and examples.
There is also a tutorial tute.htm that contrasts ADODB code with
mysql code.
>>> Files
Adodb.inc.php is the main file. You need to include only this file.
Adodb-*.inc.php are the database specific driver code.
Test.php contains a list of test commands to exercise the class library.
Adodb-session.php is the PHP4 session handling code.
Testdatabases.inc.php contains the list of databases to apply the tests on.
Benchmark.php is a simple benchmark to test the throughput of a simple SELECT
statement for databases described in testdatabases.inc.php. The benchmark
tables are created in test.php.

I have been an extremely satisfied ADODB user for several years now.
To give you something back for all your hard work, I've spent the last 3
days rewriting the adodb-session.php code.
----------
What's New
----------
Here's a list of the new code's benefits:
* Combines the functionality of the three files:
adodb-session.php
adodb-session-clob.php
adodb-cryptsession.php
each with very similar functionality, into a single file adodb-session.php.
This will ease maintenance and support issues.
* Supports multiple encryption and compression schemes.
Currently, we support:
MD5Crypt (crypt.inc.php)
MCrypt
Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)
GZip
BZip2
These can be stacked, so if you want to compress and then encrypt your
session data, it's easy.
Also, the built-in MCrypt functions will be *much* faster, and more secure,
than the MD5Crypt code.
* adodb-session.php contains a single class ADODB_Session that encapsulates
all functionality.
This eliminates the use of global vars and defines (though they are
supported for backwards compatibility).
* All user defined parameters are now static functions in the ADODB_Session
class.
New parameters include:
* encryptionKey(): Define the encryption key used to encrypt the session.
Originally, it was a hard coded string.
* persist(): Define if the database will be opened in persistent mode.
Originally, the user had to call adodb_sess_open().
* dataFieldName(): Define the field name used to store the session data, as
'DATA' appears to be a reserved word in the following cases:
ANSI SQL
IBM DB2
MS SQL Server
Postgres
SAP
* filter(): Used to support multiple, simulataneous encryption/compression
schemes.
* Debug support is improved thru _rsdump() function, which is called after
every database call.
------------
What's Fixed
------------
The new code includes several bug fixes and enhancements:
* sesskey is compared in BINARY mode for MySQL, to avoid problems with
session keys that differ only by case.
Of course, the user should define the sesskey field as BINARY, to
correctly fix this problem, otherwise performance will suffer.
* In ADODB_Session::gc(), if $expire_notify is true, the multiple DELETES in
the original code have been optimized to a single DELETE.
* In ADODB_Session::destroy(), since "SELECT expireref, sesskey FROM $table
WHERE sesskey = $qkey" will only return a single value, we don't loop on the
result, we simply process the row, if any.
* We close $rs after every use.
---------------
What's the Same
---------------
I know backwards compatibility is *very* important to you. Therefore, the
new code is 100% backwards compatible.
If you like my code, but don't "trust" it's backwards compatible, maybe we
offer it as beta code, in a new directory for a release or two?
------------
What's To Do
------------
I've vascillated over whether to use a single function to get/set
parameters:
$user = ADODB_Session::user(); // get
ADODB_Session::user($user); // set
or to use separate functions (which is the PEAR/Java way):
$user = ADODB_Session::getUser();
ADODB_Session::setUser($user);
I've chosen the former as it's makes for a simpler API, and reduces the
amount of code, but I'd be happy to change it to the latter.
Also, do you think the class should be a singleton class, versus a static
class?
Let me know if you find this code useful, and will be including it in the
next release of ADODB.
If so, I will modify the current documentation to detail the new
functionality. To that end, what file(s) contain the documentation? Please
send them to me if they are not publically available.
Also, if there is *anything* in the code that you like to see changed, let
me know.
Thanks,
Ross

When a literal character string appears where a date value is expected, the Oracle Lite database tests the string to see if it matches the formats of Oracle, SQL-92, or the value specified for this parameter in the POLITE.INI file. Setting this parameter also defines the default format used in the TO_CHAR or TO_DATE functions when no other format string is supplied. For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is yy-mm-dd or yyyy-mm-dd. Using 'RR' in the format forces two-digit years less than or equal to 49 to be interpreted as years in the 21st century (20002049), and years over 50 as years in the 20th century (19501999). Setting the RR format as the default for all two-digit year entries allows you to become year-2000 compliant.

ADOdb Active Record

ADOdb Active Record
(c) 2000-2008 John Lim (jlim#natsoft.com)
This software is dual licensed using BSD-Style and LGPL. This
means you can use it in compiled proprietary and commercial products.
- Introduction
ADOdb_Active_Record is an Object Relation Mapping (ORM) implementation using PHP. In an ORM system, the tables and rows of the database are abstracted into native PHP objects. This allows the programmer to focus more on manipulating the data and less on writing SQL queries.
This implementation differs from Zend Framework's implementation in the following ways:
- Works with PHP4 and PHP5 and provides equivalent functionality in both versions of PHP.
- ADOdb_Active_Record works when you are connected to multiple databases. Zend's only works when connected to a default database.
- Support for $ADODB_ASSOC_CASE. The field names are upper-cased, lower-cased or left in natural case depending on this setting.
- No field name conversion to camel-caps style, unlike Zend's implementation which will convert field names such as 'first_name' to 'firstName'.
- NewADOConnection::GetActiveRecords() and ADOConnection::GetActiveRecordsClass() functions in adodb.inc.php.
- Caching of table metadata so it is only queried once per table, no matter how many Active Records are created.
- The additional functionality is described below.
ADOdb_Active_Record is designed upon the principles of the "ActiveRecord" design pattern, which was first described by Martin Fowler. The ActiveRecord pattern has been implemented in many forms across the spectrum of programming languages. ADOdb_Active_Record attempts to represent the database as closely to native PHP objects as possible.
ADOdb_Active_Record maps a database table to a PHP class, and each instance of that class represents a table row. Relations between tables can also be defined, allowing the ADOdb_Active_Record objects to be nested.
- Setting the Database Connection
The first step to using ADOdb_Active_Record is to set the default connection that an ADOdb_Active_Record objects will use to connect to a database.
require_once('adodb/adodb-active-record.inc.php');
$db = NewADOConnection('mysql://root:pwd@localhost/dbname');
ADOdb_Active_Record::SetDatabaseAdapter($db);
- Table Rows as Objects
First, let's create a temporary table in our MySQL database that we can use for demonstrative purposes throughout the rest of this tutorial. We can do this by sending a CREATE query:
$db->Execute("CREATE TEMPORARY TABLE `persons` (
`id` int(10) unsigned NOT NULL auto_increment,
`name_first` varchar(100) NOT NULL default '',
`name_last` varchar(100) NOT NULL default '',
`favorite_color` varchar(100) NOT NULL default '',
PRIMARY KEY (`id`)
) ENGINE=MyISAM;
");
ADOdb_Active_Record's are object representations of table rows. Each table in the database is represented by a class in PHP. To begin working with a table as a ADOdb_Active_Record, a class that extends ADOdb_Active_Records needs to be created for it.
class Person extends ADOdb_Active_Record{}
$person = new Person();
In the above example, a new ADOdb_Active_Record object $person was created to access the "persons" table. Zend_Db_DataObject takes the name of the class, pluralizes it (according to American English rules), and assumes that this is the name of the table in the database.
This kind of behavior is typical of ADOdb_Active_Record. It will assume as much as possible by convention rather than explicit configuration. In situations where it isn't possible to use the conventions that ADOdb_Active_Record expects, options can be overridden as we'll see later.
- Table Columns as Object Properties
When the $person object was instantiated, ADOdb_Active_Record read the table metadata from the database itself, and then exposed the table's columns (fields) as object properties.
Our "persons" table has three fields: "name_first", "name_last", and "favorite_color". Each of these fields is now a property of the $person object. To see all these properties, use the ADOdb_Active_Record::getAttributeNames() method:
var_dump($person->getAttributeNames());
/**
* Outputs the following:
* array(4) {
* [0]=>

* [1]=>

* [2]=>
* string(8) "name_last"
* [3]=>
* string(13) "favorite_color"
* }
*/
One big difference between ADOdb and Zend's implementation is we do not automatically convert to camelCaps style.
- Inserting and Updating a Record
An ADOdb_Active_Record object is a representation of a single table row. However, when our $person object is instantiated, it does not reference any particular row. It is a blank record that does not yet exist in the database. An ADOdb_Active_Record object is considered blank when its primary key is NULL. The primary key in our persons table is "id".
To insert a new record into the database, change the object's properties and then call the ADOdb_Active_Record::save() method:
$person = new Person();
$person->nameFirst = 'Andi';
$person->nameLast = 'Gutmans';
$person->save();
Oh, no! The above code snippet does not insert a new record into the database. Instead, outputs an error:
1048: Column 'name_first' cannot be null
This error occurred because MySQL rejected the INSERT query that was generated by ADOdb_Active_Record. If exceptions are enabled in ADOdb and you are using PHP5, an error will be thrown. In the definition of our table, we specified all of the fields as NOT NULL; i.e., they must contain a value.
ADOdb_Active_Records are bound by the same contraints as the database tables they represent. If the field in the database cannot be NULL, the corresponding property in the ADOdb_Active_Record also cannot be NULL. In the example above, we failed to set the property $person->favoriteColor, which caused the INSERT to be rejected by MySQL.
To insert a new ADOdb_Active_Record in the database, populate all of ADOdb_Active_Record's properties so that they satisfy the constraints of the database table, and then call the save() method:
/**
* Calling the save() method will successfully INSERT
* this $person into the database table.
*/
$person = new Person();
$person->name_first = 'Andi';
$person->name_last = 'Gutmans';
$person->favorite_color = 'blue';
$person->save();
Once this $person has been INSERTed into the database by calling save(), the primary key can now be read as a property. Since this is the first row inserted into our temporary table, its "id" will be 1:
var_dump($person->id);
/**
* Outputs the following:
* string(1)
*/
From this point on, updating it is simply a matter of changing the object's properties and calling the save() method again:
$person->favorite_color = 'red';
$person->save();
The code snippet above will change the favorite color to red, and then UPDATE the record in the database.
ADOdb Specific Functionality
- Setting the Table Name
The default behaviour on creating an ADOdb_Active_Record is to "pluralize" the class name and
use that as the table name. Often, this is not the case. For example, the Person class could be reading
from the "People" table.
We provide two ways to define your own table:
1. Use a constructor parameter to override the default table naming behaviour.
class Person extends ADOdb_Active_Record{}
$person = new Person('People');
2. Define it in a class declaration:
class Person extends ADOdb_Active_Record
{
var $_table = 'People';
}
$person = new Person();
- $ADODB_ASSOC_CASE
This allows you to control the case of field names and properties. For example, all field names in Oracle are upper-case by default. So you
can force field names to be lowercase using $ADODB_ASSOC_CASE. Legal values are as follows:
0: lower-case
1: upper-case
2: native-case
So to force all Oracle field names to lower-case, use
$ADODB_ASSOC_CASE = 0;
$person = new Person('People');
$person->name = 'Lily';
$ADODB_ASSOC_CASE = 2;
$person2 = new Person('People');
$person2->NAME = 'Lily';

Differences between ADOdb and ADO
Database Driver Guide
Change Log
Introduction
PHP's database access functions are not standardised. This creates a need for
a database class library to hide the differences between the different database
API's (encapsulate the differences) so we can easily switch databases. PHP 4.0.5 or later
is now required (because we use array-based str_replace).
We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL Anywhere, Informix,
PostgreSQL, FrontBase, SQLite, Interbase (Firebird and Borland variants), Foxpro, Access, ADO, DB2, SAP DB and ODBC.
We have had successful reports of connecting to Progress and CacheLite via ODBC. We hope more people
will contribute drivers to support other databases.
PHP4 supports session variables. You can store your session information using
ADOdb for true portability and scalability. See adodb-session.php for more information.
Also read
for tips on writing
portable SQL.
Unique Features of ADOdb
- Easy for Windows programmers to adapt to because many of the conventions
are similar to Microsoft's ADO.
- Unlike other PHP database classes which focus only on select statements,
we provide support code to handle inserts and updates which can be adapted
to multiple databases quickly. Methods are provided for date handling,
string concatenation and string quoting characters for differing databases.
- A metatype system is built in so that we can figure out that types
such as CHAR, TEXT and STRING are equivalent in different databases.
- Easy to port because all the database dependant code are stored in
stub functions. You do not need to port the core logic of the classes.
- Portable table and index creation with the datadict classes.
- Database performance monitoring and SQL tuning with the performance monitoring classes.
- Database-backed sessions with the session management classes. Supports session expiry notification.
- Object-Relational Mapping using ADOdb_Active_Record classes.
How People are using ADOdb
Here are some examples of how people are using ADOdb (for a much longer list,
visit ):
- is a commercial data grid
component that allows both cool Web designers and serious unshaved
programmers to develop and maintain databases on the Web easily.
Developed by the author of ADOdb.
- allows you to script PHP in the popular Web page editor. Database handling provided by ADOdb.
-
(ACID): PHP-based analysis engine to search and process a database of
security incidents generated by security-related software such as IDSes
and firewalls (e.g. Snort, ipchains). By Roman Danyliw.
- is a very
popular free content management system and weblog system. It offers
full CSS support, HTML 4.01 transitional compliance throughout, an
advanced blocks system, and is fully multi-lingual enabled.
-
is another free content management system for managing information and
integrated modules on your internet, intranet- and extranet-sites. From
Norway.
- is a full featured accounting, inventory, and job tracking application. It is licensed under the GPL, and developed by Noguska.
Feature Requests and Bug Reports
Feature requests and bug reports can be emailed to jlim#natsoft.com.my
or posted to the ADOdb Help forums at .
Installation Guide
Make sure you are running PHP 4.0.5 or later.
Unpack all the files into a directory accessible by your webserver.
To test, try modifying some of the tutorial examples. Make sure you customize
the connection settings correctly. You can debug using $db->debug = true as shown below:
<?php
include('adodb/adodb.inc.php');
$db = ADONewConnection($dbdriver); # eg 'mysql' or 'postgres'
$db->debug = true;
$db->Connect($server, $user, $password, $database);
$rs = $db->Execute('select * from some_small_table');
print "<pre>";
print_r($rs->GetRows());
print "</pre>";
?>
Minimum Install
For developers who want to release a minimal install of ADOdb, you will need:
- adodb.inc.php
- adodb-lib.inc.php
- adodb-time.inc.php
- drivers/adodb-$database.inc.php
- license.txt (for legal reasons)
- adodb-php4.inc.php
- adodb-iterator.inc.php (php5 functionality)
Optional:
- adodb-error.inc.php and lang/adodb-$lang.inc.php (if you use MetaError())
- adodb-csvlib.inc.php (if you use cached recordsets - CacheExecute(), etc)
- adodb-exceptions.inc.php and adodb-errorhandler.inc.php (if you use adodb error handler or php5 exceptions).
- adodb-active-record.inc.php if you use Active Records.
Code Initialization Examples
When running ADOdb, at least two files are loaded. First is adodb/adodb.inc.php,
which contains all functions used by all database classes. The code specific
to a particular database is in the adodb/driver/adodb-????.inc.php file.
For example, to connect to a mysql database:
include('/path/to/set/here/adodb.inc.php');
$conn =ADONewConnection('mysql');
Whenever you need to connect to a database, you create a Connection object
using the ADONewConnection($driver) function.
NewADOConnection($driver) is an alternative name for the same function.
At this point, you are not connected to the database (no longer true if you pass in a dsn). You will first need to decide
whether to use persistent or non-persistent connections. The advantage of persistent
connections is that they are faster, as the database connection is never closed (even
when you call Close()). Non-persistent connections take up much fewer resources though,
reducing the risk of your database and your web-server becoming overloaded.
For persistent connections,
use $conn->PConnect(),
or $conn->Connect() for non-persistent connections.
Some database drivers also support NConnect(), which forces
the creation of a new connection.
Connection Gotcha: If you create two connections, but both use the same userid and password,
PHP will share the same connection. This can cause problems if the connections are meant to
different databases. The solution is to always use different userid's for different databases,
or use NConnect().
Data Source Name (DSN) Support
Since ADOdb 4.51, you can connect to a database by passing a dsn to NewADOConnection() (or ADONewConnection, which is
the same function). The dsn format is:
$driver://$username:$password@hostname/$database?options[=value]
NewADOConnection() calls Connect() or PConnect() internally for you. If the connection fails, false is returned.
# non-persistent connection
$dsn = 'mysql://root:pwd@localhost/mydb';
$db = NewADOConnection($dsn);
if (!$db) die("Connection failed");
# no need to call connect/pconnect!
$arr = $db->GetArray("select * from table");
# persistent connection
$dsn2 = 'mysql://root:pwd@localhost/mydb?persist';
If you have special characters such as /:?_ in your dsn, then you need to rawurlencode them first:
$pwd = rawurlencode($pwd);
$dsn = "mysql://root:$pwd@localhost/mydb";
$dsn2=rawurlencode("sybase_ase")."://user:pass@host/path?query";
Legal options are:
For all drivers
'persist', 'persistent', 'debug', 'fetchmode', 'new'
Interbase/Firebird
'dialect','charset','buffers','role'
M'soft ADO
'charpage'
MySQL
'clientflags'
MySQLi
'port', 'socket', 'clientflags'
Oci8
'nls_date_format','charset'
For all drivers, when the options persist or persistent are set, a persistent connection is forced; similarly, when new is set, then
a new connection will be created using NConnect if the underlying driver supports it.
The debug option enables debugging. The fetchmode calls SetFetchMode().
If no value is defined for an option, then the value is set to 1.
ADOdb DSN's are compatible with version 1.0 of PEAR DB's DSN format.
Examples of Connecting to Databases
MySQL and Most Other Database Drivers
MySQL connections are very straightforward, and the parameters are identical
to mysql_connect:
$conn =ADONewConnection('mysql');
$conn->PConnect('localhost','userid','password','database');
# or dsn
$dsn = 'mysql://user:pwd@localhost/mydb';
$conn = ADONewConnection($dsn); # no need for Connect()
# or persistent dsn
$dsn = 'mysql://user:pwd@localhost/mydb?persist';
$conn = ADONewConnection($dsn); # no need for PConnect()
# a more complex example:
$pwd = urlencode($pwd);
$flags = MYSQL_CLIENT_COMPRESS;
$dsn = "mysql://user:$pwd@localhost/mydb?persist&clientflags=$flags";
$conn = ADONewConnection($dsn); # no need for PConnect()
For most drivers, you can use the standard function: Connect($server, $user, $password, $database), or
a DSN since ADOdb 4.51. Exceptions to this are listed below.
PDO
PDO, which only works with PHP5, accepts a driver specific connection string:
$conn = NewADOConnection('pdo');
$conn->Connect('mysql:host=localhost',$user,$pwd,$mydb);
$conn->Connect('mysql:host=localhost;dbname=mydb',$user,$pwd);
$conn->Connect("mysql:host=localhost;dbname=mydb;username=$user;password=$pwd");
The DSN mechanism is also supported:
$conn = NewADOConnection("pdo_mysql://user:pwd@localhost/mydb?persist"); # persist is optional
PostgreSQL
PostgreSQL 7 and 8 accepts connections using:
a. the standard connection string:
$conn = ADONewConnection('postgres');
$conn->PConnect('host=localhost port=5432 dbname=mary');
b. the classical 4 parameters:
$conn->PConnect('localhost','userid','password','database');
c. dsn:
$dsn = 'postgres://user:pwd@localhost/mydb?persist'; # persist is optional
$conn = ADONewConnection($dsn); # no need for Connect/PConnect
LDAP
Here is an example of querying a LDAP server. Thanks to Josh Eldridge for the driver and this example:
require('/path/to/adodb.inc.php');
/* Make sure to set this BEFORE calling Connect() */
$LDAP_CONNECT_OPTIONS = Array(
Array ("OPTION_NAME"=>LDAP_OPT_DEREF, "OPTION_VALUE"=>2),
Array ("OPTION_NAME"=>LDAP_OPT_SIZELIMIT,"OPTION_VALUE"=>100),
Array ("OPTION_NAME"=>LDAP_OPT_TIMELIMIT,"OPTION_VALUE"=>30),
Array ("OPTION_NAME"=>LDAP_OPT_PROTOCOL_VERSION,"OPTION_VALUE"=>3),
Array ("OPTION_NAME"=>LDAP_OPT_ERROR_NUMBER,"OPTION_VALUE"=>13),
Array ("OPTION_NAME"=>LDAP_OPT_REFERRALS,"OPTION_VALUE"=>FALSE),
Array ("OPTION_NAME"=>LDAP_OPT_RESTART,"OPTION_VALUE"=>FALSE)
);
$host = 'ldap.baylor.edu';
$ldapbase = 'ou=People,o=Baylor University,c=US';
$ldap = NewADOConnection( 'ldap' );
$ldap->Connect( $host, $user_name='', $password='', $ldapbase );
echo "<pre>";
print_r( $ldap->ServerInfo() );
$ldap->SetFetchMode(ADODB_FETCH_ASSOC);
$userName = 'eldridge';
$filter="(|(CN=$userName*)(sn=$userName*)(givenname=$userName*)(uid=$userName*))";
$rs = $ldap->Execute( $filter );
if ($rs)
while ($arr = $rs->FetchRow()) {
print_r($arr);
}
$rs = $ldap->Execute( $filter );
if ($rs)
while (!$rs->EOF) {
print_r($rs->fields);
$rs->MoveNext();
}
print_r( $ldap->GetArray( $filter ) );
print_r( $ldap->GetRow( $filter ) );
$ldap->Close();
echo "</pre>";
Using DSN:
$dsn = "ldap://ldap.baylor.edu/ou=People,o=Baylor University,c=US";
$db = NewADOConnection($dsn);
Interbase/Firebird
You define the database in the $host parameter:
$conn =ADONewConnection('ibase');
$conn->PConnect('localhost:c:\ibase\employee.gdb','sysdba','masterkey');
Or dsn:
$dsn = 'firebird://user:pwd@localhost/mydb?persist&dialect=3'; # persist is optional
$conn = ADONewConnection($dsn); # no need for Connect/PConnect
SQLite
Sqlite will create the database file if it does not exist.
$conn =ADONewConnection('sqlite');
$conn->PConnect('c:\path\to\sqlite.db'); # sqlite will create if does not exist
Or dsn:
$path = urlencode('c:\path\to\sqlite.db');
$dsn = "sqlite://$path/?persist"; # persist is optional
$conn = ADONewConnection($dsn); # no need for Connect/PConnect
Oracle (oci8)
With oci8, you can connect in multiple ways. Note that oci8 works fine with
newer versions of the Oracle, eg. 9i and 10g.
a. PHP and Oracle reside on the same machine, use default SID.
$conn->Connect(false, 'scott', 'tiger');
b. TNS Name defined in tnsnames.ora (or ONAMES or HOSTNAMES), eg. 'myTNS'
$conn->PConnect(false, 'scott', 'tiger', 'myTNS');
or
$conn->PConnect('myTNS', 'scott', 'tiger');
c. Host Address and SID
$conn->connectSID = true;
$conn->Connect('192.168.0.1', 'scott', 'tiger', 'SID');
d. Host Address and Service Name
$conn->Connect('192.168.0.1', 'scott', 'tiger', 'servicename');
e. Oracle connection string:
$cstr = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=$host)(PORT=$port))
(CONNECT_DATA=(SID=$sid)))";
$conn->Connect($cstr, 'scott', 'tiger');
f. ADOdb dsn:
$dsn = 'oci8://user:pwd@tnsname/?persist'; # persist is optional
$conn = ADONewConnection($dsn); # no need for Connect/PConnect
$dsn = 'oci8://user:pwd@host/sid';
$conn = ADONewConnection($dsn);
$dsn = 'oci8://user:pwd@/'; # oracle on local machine
$conn = ADONewConnection($dsn);
You can also set the charSet for Oracle 9.2 and later, supported since PHP 4.3.2, ADOdb 4.54:
$conn->charSet = 'we8iso8859p1';
$conn->Connect(...);
# or
$dsn = 'oci8://user:pwd@tnsname/?charset=WE8MSWIN1252';
$db = ADONewConnection($dsn);
DSN-less ODBC ( Access, MSSQL and DB2 examples)
ODBC DSN's can be created in the ODBC control panel, or you can use a DSN-less
connection.To use DSN-less connections with ODBC you need PHP 4.3 or later.
For Microsoft Access:
$db = ADONewConnection('access');
$dsn = "Driver={Microsoft Access Driver (*.mdb)};Dbq=d:\\northwind.mdb;Uid=Admin;Pwd=;";
$db->Connect($dsn);
For Microsoft SQL Server:
$db = ADONewConnection('odbc_mssql');
$dsn = "Driver={SQL Server};Server=localhost;Database=northwind;";
$db->Connect($dsn,'userid','password');
or if you prefer to use the mssql extension (which is limited to mssql 6.5 functionality):
$db = ADONewConnection('mssql');
$db->Execute('localhost', 'userid', 'password', 'northwind');
For DB2:
$dbms = 'db2'; # or 'odbc_db2' if db2 extension not available
$db = ADONewConnection($dbms);
$dsn = "driver={IBM db2 odbc DRIVER};Database=sample;hostname=localhost;port=50000;protocol=TCPIP;".
"uid=root; pwd=secret";
$db->Connect($dsn);
DSN-less Connections with ADO
If you are using versions of PHP earlier than PHP 4.3.0, DSN-less connections
only work with Microsoft's ADO, which is Microsoft's COM based API. An example
using the ADOdb library and Microsoft's ADO:
<?php
include('adodb.inc.php');
$db =ADONewConnection("ado_mssql");
print "<h1>Connecting DSN-less $db->databaseType...</h1>";
$myDSN="PROVIDER=MSDASQL;DRIVER={SQL Server};"
. "SERVER=flipper;DATABASE=ai;UID=sa;PWD=;" ;
$db->Connect($myDSN);
$rs = $db->Execute("select * from table");
$arr = $rs->GetArray();
print_r($arr);
?>
High Speed ADOdb - tuning tips
ADOdb is a big class library, yet it all other PHP class
libraries in performance. This is because it is designed in a layered fashion,
like an onion, with the fastest functions in the innermost layer. Stick to the
following functions for best performance:
Innermost Layer
Connect, PConnect, NConnect
Execute, CacheExecute
SelectLimit, CacheSelectLimit
MoveNext, Close
qstr, Affected_Rows, Insert_ID
The fastest way to access the field data is by accessing the array $recordset->fields
directly. Also set the global variables $ADODB_FETCH_MODE
= ADODB_FETCH_NUM, and (for oci8, ibase/firebird and odbc) $ADODB_COUNTRECS = false
before you connect to your database.
Consider using bind parameters if your database supports it, as it improves
query plan reuse. Use ADOdb's performance tuning system to identify bottlenecks
quickly. At the time of writing (Dec 2003), this means oci8 and odbc drivers.
Lastly make sure you have a PHP accelerator cache installed such as APC, Turck
MMCache, Zend Accelerator or ionCube.
Some examples:
Fastest data retrieval using PHP Fastest data retrieval using ADOdb extension
$rs = $rs->Execute($sql);
while (!$rs->EOF) {
var_dump($rs->fields);
$rs->MoveNext();
}
$rs = $rs->Execute($sql);
$array = adodb_getall($rs);
var_dump($array);
Advanced Tips
If you have the installed,
you can replace your calls to $rs->MoveNext() with adodb_movenext($rs).
This doubles the speed of this operation. For retrieving entire recordsets at once,
use GetArray(), which uses the high speed extension function adodb_getall($rs) internally.
Execute() is the default way to run queries. You can use the low-level functions _Execute() and _query()
to reduce query overhead. Both these functions share the same parameters as Execute().
If you do not have any bind parameters or your database supports
binding (without emulation),
then you can call _Execute() directly. Calling this function bypasses
bind emulation. Debugging is still supported in _Execute().
If you do not require debugging facilities nor emulated
binding, and do not require a recordset to be returned, then you can
call _query. This is great for inserts, updates and deletes. Calling
this function
bypasses emulated binding, debugging, and recordset handling. Either
the resultid, true or false are returned by _query().
For Informix, you can disable scrollable cursors with $db->cursorType = 0.
Hacking ADOdb Safely
You might want to modify ADOdb for your own purposes. Luckily you can
still maintain backward compatibility by sub-classing ADOdb and using the $ADODB_NEWCONNECTION
variable. $ADODB_NEWCONNECTION allows you to override the behaviour of ADONewConnection().
ADOConnection() checks for this variable and will call
the function-name stored in this variable if it is defined.
In the following example, new functionality for the connection object
is placed in the hack_mysql and hack_postgres7 classes. The recordset class naming convention
can be controlled using $rsPrefix. Here we set it to 'hack_rs_', which will make ADOdb use
hack_rs_mysql and hack_rs_postgres7 as the recordset classes.
class hack_mysql extends adodb_mysql {
var $rsPrefix = 'hack_rs_';
/* Your mods here */
}
class hack_rs_mysql extends ADORecordSet_mysql {
/* Your mods here */
}
class hack_postgres7 extends adodb_postgres7 {
var $rsPrefix = 'hack_rs_';
/* Your mods here */
}
class hack_rs_postgres7 extends ADORecordSet_postgres7 {
/* Your mods here */
}
$ADODB_NEWCONNECTION = 'hack_factory';
function hack_factory($driver)
{
if ($driver !== 'mysql' && $driver !== 'postgres7') return false;
$driver = 'hack_'.$driver;
$obj = new $driver();
return $obj;
}
include_once('adodb.inc.php');
Don't forget to call the constructor of the parent class in
your constructor. If you want to use the default ADOdb drivers return
false in the above hack_factory() function.
Also you can define your own ADORecordSet_empty() class, by defining a class $$this->rsPrefix.'empty' since 4.96/5.02.
PHP5 Features
ADOdb 4.02 or later will transparently determine which version of PHP you are using.
If PHP5 is detected, the following features become available:
- PDO: PDO drivers are available. See the connection examples. Currently PDO drivers are
not as powerful as native drivers, and should be treated as experimental.
- Foreach iterators: This is a very natural way of going through a recordset:
$ADODB_FETCH_MODE = ADODB_FETCH_NUM;
$rs = $db->Execute($sql);
foreach($rs as $k =gt; $row) {
echo "r1=".$row[0]." r2=".$row[1]."<br>";
}
- Exceptions: Just include adodb-exceptions.inc.php and you can now
catch exceptions on errors as they occur.
include("../adodb-exceptions.inc.php");
include("../adodb.inc.php");
try {
$db = NewADOConnection("oci8");
$db->Connect('','scott','bad-password');
} catch (exception $e) {
var_dump($e);
adodb_backtrace($e->gettrace());
}
Note that reaching EOF is not considered an error nor an exception.

The "Tested" column indicates how extensively the code has been tested
and used.
A = well tested and used by many people
B = tested and usable, but some features might not be implemented
C = user contributed or experimental driver. Might not fully support all of
the latest features of ADOdb.
The column "RecordCount() usable" indicates whether RecordCount()
return the number of rows, or returns -1 when a SELECT statement is executed.
If this column displays Y/N then the RecordCount() is emulated when the global
variable $ADODB_COUNTRECS=true (this is the default). Note that for large recordsets,
it might be better to disable RecordCount() emulation because substantial amounts
of memory are required to cache the recordset for counting. Also there is a
speed penalty of 40-50% if emulation is required. This is emulated in most databases
except for PostgreSQL and MySQL. This variable is checked every time a query
is executed, so you can selectively choose which recordsets to count.
Tutorials
Example 1: Select Statement
Task: Connect to the Access Northwind DSN, display the first 2 columns of each
row.
In this example, we create a ADOConnection object, which represents the connection
to the database. The connection is initiated with PConnect,
which is a persistent connection. Whenever we want to query the database, we
call the ADOConnection.Execute()
function. This returns an ADORecordSet object which is actually a cursor that
holds the current row in the array fields[].
We use MoveNext()
to move from row to row.
NB: A useful function that is not used in this example is SelectLimit,
which allows us to limit the number of rows shown.
<?
include('adodb.inc.php'); # load code common to ADOdb
$conn =ADONewConnection('access'); # create a connection
$conn->PConnect('northwind'); # connect to MS-Access, northwind DSN
$recordSet =$conn->Execute('select * from products');
if (!$recordSet)
print $conn->ErrorMsg();
else
while (!$recordSet->EOF) {
print $recordSet->fields[0].' '.$recordSet->fields[1].'<BR>';
$recordSet->MoveNext();
}
$recordSet->Close(); # optional
$conn->Close(); # optional
?>
The $recordSet returned stores
the current row in the $recordSet->fields
array, indexed by column number (starting from zero). We use the MoveNext()
function to move to the next row. The EOF
property is set to true when end-of-file is reached. If an error occurs in Execute(),
we return false instead of a recordset.
The $recordSet->fields[] array is generated by the PHP database
extension. Some database extensions only index by number and do not index the
array by field name. To force indexing by name - that is associative arrays
- use the SetFetchMode function. Each recordset saves and uses whatever fetch
mode was set when the recordset was created in Execute() or SelectLimit().
$db->SetFetchMode(ADODB_FETCH_NUM);
$rs1 = $db->Execute('select * from table');
$db->SetFetchMode(ADODB_FETCH_ASSOC);
$rs2 = $db->Execute('select * from table');
print_r($rs1->fields); # shows array([0]=gt;'v0',[1] =gt;'v1')
print_r($rs2->fields); # shows array(['col1']=gt;'v0',['col2'] =gt;'v1')
To get the number of rows in the select statement, you can use $recordSet->RecordCount().
Note that it can return -1 if the number of rows returned cannot be determined.
Example 2: Advanced Select with Field Objects
Select a table, display the first two columns. If the second column is a date
or timestamp, reformat the date to US format.
<?
include('adodb.inc.php'); # load code common to ADOdb
$conn =ADONewConnection('access'); # create a connection
$conn->PConnect('northwind'); # connect to MS-Access, northwind dsn
$recordSet =$conn->Execute('select CustomerID,OrderDate from Orders');
if (!$recordSet)
print $conn->ErrorMsg();
else
while (!$recordSet->EOF) {
$fld = $recordSet->FetchField(1);
$type = $recordSet->MetaType($fld->type);
if ( $type == 'D' || $type == 'T')
print $recordSet->fields[0].' '.
$recordSet->UserDate($recordSet->fields[1],'m/d/Y').'<BR>';
else
print $recordSet->fields[0].' '.$recordSet->fields[1].'<BR>';
$recordSet->MoveNext();
}
$recordSet->Close(); # optional
$conn->Close(); # optional
?>
In this example, we check the field type of the second column using FetchField().
This returns an object with at least 3 fields.
- name: name of column
- type: native field type of column
- max_length: maximum length of field. Some databases such as MySQL
do not return the maximum length of the field correctly. In these cases max_length
will be set to -1.
We then use MetaType()
to translate the native type to a generic type. Currently the following
generic types are defined:
- C: character fields that should be shown in a <input type="text">
tag.
- X: TeXt, large text fields that should be shown in a <textarea>
- B: Blobs, or Binary Large Objects. Typically images.
- D: Date field
- T: Timestamp field
- L: Logical field (boolean or bit-field)
- I: Integer field
- N: Numeric field. Includes autoincrement, numeric, floating point,
real and integer.
- R: Serial field. Includes serial, autoincrement integers. This works
for selected databases.
If the metatype is of type date or timestamp, then we print it using the user
defined date format with UserDate(),
which converts the PHP SQL date string format to a user defined one. Another
use for MetaType()
is data validation before doing an SQL insert or update.
Example 3: Inserting
Insert a row to the Orders table containing dates and strings that need to
be quoted before they can be accepted by the database, eg: the single-quote
in the word John's.
<?
include('adodb.inc.php'); # load code common to ADOdb
$conn =ADONewConnection('access'); # create a connection
$conn->PConnect('northwind'); # connect to MS-Access, northwind dsn
$shipto = $conn->qstr("John's Old Shoppe");
$sql = "insert into orders (customerID,EmployeeID,OrderDate,ShipName) ";
$sql .= "values ('ANATR',2,".$conn->DBDate(time()).",$shipto)";
if ($conn->Execute($sql) === false) {
print 'error inserting: '.$conn->ErrorMsg().'<BR>';
}
?>
In this example, we see the advanced date and quote handling facilities of
ADOdb. The unix timestamp (which is a long integer) is appropriately formated
for Access with DBDate(),
and the right escape character is used for quoting the John's Old Shoppe,
which is John''s Old Shoppe and not PHP's default John's
Old Shoppe with qstr().
Observe the error-handling of the Execute statement. False is returned by
Execute() if an error occured. The error message
for the last error that occurred is displayed in ErrorMsg().
Note: php_track_errors might have to be enabled for error messages to
be saved.
Example 4: Debugging
<?
include('adodb.inc.php'); # load code common to ADOdb
$conn =ADONewConnection('access'); # create a connection
$conn->PConnect('northwind'); # connect to MS-Access, northwind dsn
$shipto = $conn->qstr("John's Old Shoppe");
$sql = "insert into orders (customerID,EmployeeID,OrderDate,ShipName) ";
$sql .= "values ('ANATR',2,".$conn->FormatDate(time()).",$shipto)";
$conn->debug = true;
if ($conn->Execute($sql) === false) print 'error inserting';
?>
In the above example, we have turned on debugging by setting debug = true.
This will display the SQL statement before execution, and also show any error
messages. There is no need to call ErrorMsg()
in this case. For displaying the recordset, see the rs2html()
example.
Also see the section on Custom Error Handlers.
Example 5: MySQL and Menus
Connect to MySQL database agora, and generate a <select> menu
from an SQL statement where the <option> captions are in the 1st column,
and the value to send back to the server is in the 2nd column.
<?
include('adodb.inc.php'); # load code common to ADOdb
$conn =ADONewConnection('mysql'); # create a connection
$conn->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
$sql = 'select CustomerName, CustomerID from customers';
$rs = $conn->Execute($sql);
print $rs->GetMenu('GetCust','Mary Rosli');
?>
Here we define a menu named GetCust, with the menu option 'Mary Rosli' selected.
See GetMenu().
We also have functions that return the recordset as an array: GetArray(),
and as an associative array with the key being the first column: GetAssoc().
Example 6: Connecting to 2 Databases At Once
<?
include('adodb.inc.php'); # load code common to ADOdb
$conn1 =ADONewConnection('mysql'); # create a mysql connection
$conn2 =ADONewConnection('oracle'); # create a oracle connection
$conn1->PConnect($server, $userid, $password, $database);
$conn2->PConnect(false, $ora_userid, $ora_pwd, $oraname);
$conn1->Execute('insert ...');
$conn2->Execute('update ...');
?>
Example 7: Generating Update and Insert SQL
Since ADOdb 4.56, we support AutoExecute(),
which simplifies things by providing an advanced wrapper for GetInsertSQL() and GetUpdateSQL(). For example,
an INSERT can be carried out with:
$record["firstname"] = "Bob";
$record["lastname"] = "Smith";
$record["created"] = time();
$insertSQL = $conn->AutoExecute($rs, $record, 'INSERT');
and an UPDATE with:
$record["firstname"] = "Caroline";
$record["lastname"] = "Smith"; # Update Caroline's lastname from Miranda to Smith
$insertSQL = $conn->AutoExecute($rs, $record, 'UPDATE', 'id = 1');
The rest of this section is out-of-date:
ADOdb 1.31 and later supports two new recordset functions: GetUpdateSQL( ) and
GetInsertSQL( ). This allow you to perform a "SELECT * FROM table query WHERE...",
make a copy of the $rs->fields, modify the fields, and then generate the SQL to
update or insert into the table automatically.
We show how the functions can be used when accessing a table with the following
fields: (ID, FirstName, LastName, Created).
Before these functions can be called, you need to initialize the recordset
by performing a select on the table. Idea and code by Jonathan Younger jyounger#unilab.com.
Since ADOdb 2.42, you can pass a table name instead of a recordset into
GetInsertSQL (in $rs), and it will generate an insert statement for that table.
<?
#==============================================
# SAMPLE GetUpdateSQL() and GetInsertSQL() code
#==============================================
include('adodb.inc.php');
include('tohtml.inc.php');
#==========================
# This code tests an insert
$sql = "SELECT * FROM ADOXYZ WHERE id = -1";
# Select an empty record from the database
$conn =ADONewConnection("mysql"); # create a connection
$conn->debug=1;
$conn->PConnect("localhost", "admin", "", "test"); # connect to MySQL, testdb
$rs = $conn->Execute($sql); # Execute the query and get the empty recordset
$record = array(); # Initialize an array to hold the record data to insert
# Set the values for the fields in the record
# Note that field names are case-insensitive
$record["firstname"] = "Bob";
$record["lastNamE"] = "Smith";
$record["creaTed"] = time();
# Pass the empty recordset and the array containing the data to insert
# into the GetInsertSQL function. The function will process the data and return
# a fully formatted insert sql statement.
$insertSQL = $conn->GetInsertSQL($rs, $record);
$conn->Execute($insertSQL); # Insert the record into the database
#==========================
# This code tests an update
$sql = "SELECT * FROM ADOXYZ WHERE id = 1";
# Select a record to update
$rs = $conn->Execute($sql); # Execute the query and get the existing record to update
$record = array(); # Initialize an array to hold the record data to update
# Set the values for the fields in the record
# Note that field names are case-insensitive
$record["firstname"] = "Caroline";
$record["LasTnAme"] = "Smith"; # Update Caroline's lastname from Miranda to Smith
# Pass the single record recordset and the array containing the data to update
# into the GetUpdateSQL function. The function will process the data and return
# a fully formatted update sql statement with the correct WHERE clause.
# If the data has not changed, no recordset is returned
$updateSQL = $conn->GetUpdateSQL($rs, $record);
$conn->Execute($updateSQL); # Update the record in the database
$conn->Close();
?>
$ADODB_FORCE_TYPE
The behaviour of AutoExecute(), GetUpdateSQL() and GetInsertSQL()
when converting empty or null PHP variables to SQL is controlled by the
global $ADODB_FORCE_TYPE variable. Set it to one of the values below. Default
is ADODB_FORCE_VALUE (3):
0 = ignore empty fields. All empty fields in array are ignored.
1 = force null. All empty, php null and string 'null' fields are changed to sql NULL values.
2 = force empty. All empty, php null and string 'null' fields are changed to sql empty '' or 0 values.
3 = force value. Value is left as it is. Php null and string 'null' are set to sql NULL values and
empty fields '' are set to empty '' sql values.
define('ADODB_FORCE_IGNORE',0);
define('ADODB_FORCE_NULL',1);
define('ADODB_FORCE_EMPTY',2);
define('ADODB_FORCE_VALUE',3);
Thanks to Niko (nuko#mbnet.fi) for the $ADODB_FORCE_TYPE code.
Note: the constant ADODB_FORCE_NULLS is obsolete since 4.52 and is ignored. Set $ADODB_FORCE_TYPE = ADODB_FORCE_NULL
for equivalent behaviour.
Since 4.62, the table name to be used can be overridden by setting $rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is called.
Example 8: Implementing Scrolling with Next and Previous
The following code creates a very simple recordset pager, where you can scroll
from page to page of a recordset.
include_once('../adodb.inc.php');
include_once('../adodb-pager.inc.php');
session_start();
$db = NewADOConnection('mysql');
$db->Connect('localhost','root','','xphplens');
$sql = "select * from adoxyz ";
$pager = new ADODB_Pager($db,$sql);
$pager->Render($rows_per_page=5);
This will create a basic record pager that looks like this:
|< <<
>> >|
ID
First Name
Last Name
Date Created

Page 8/10
The number of rows to display at one time is controled by the Render($rows)
method. If you do not pass any value to Render(), ADODB_Pager will default to
10 records per page.
You can control the column titles by modifying your SQL (supported by most
databases):
$sql = 'select id as "ID", firstname as "First Name",
lastname as "Last Name", created as "Date Created"
from adoxyz';
The above code can be found in the adodb/tests/testpaging.php example
included with this release, and the class ADODB_Pager in adodb/adodb-pager.inc.php.
The ADODB_Pager code can be adapted by a programmer so that the text links can
be replaced by images, and the dull white background be replaced with more interesting
colors.
You can also allow display of html by setting $pager->htmlSpecialChars = false.
Some of the code used here was contributed by Iván Oliva and Cornel
G.
Example 9: Exporting in CSV or Tab-Delimited Format
We provide some helper functions to export in comma-separated-value (CSV) and
tab-delimited formats:
include_once('/path/to/adodb/toexport.inc.php');
include_once('/path/to/adodb/adodb.inc.php');
$db =NewADOConnection('mysql');
$db->Connect($server, $userid, $password, $database);
$rs = $db->Execute('select fname as "First Name", surname as "Surname" from table');
print "<pre>";
print rs2csv($rs); # return a string, CSV formatprint '<hr>';
$rs->MoveFirst(); # note, some databases do not support MoveFirst
print rs2tab($rs,false); # return a string, tab-delimited
# false == suppress field names in first line
print '<hr>';
$rs->MoveFirst();
rs2tabout($rs); # send to stdout directly (there is also an rs2csvout function)
print "</pre>";
$rs->MoveFirst();
$fp = fopen($path, "w");
if ($fp) {
rs2csvfile($rs, $fp); # write to file (there is also an rs2tabfile function)
fclose($fp);
}
Carriage-returns or newlines are converted to spaces. Field names are returned
in the first line of text. Strings containing the delimiter character are quoted
with double-quotes. Double-quotes are double-quoted again. This conforms to
Excel import and export guide-lines.
All the above functions take as an optional last parameter, $addtitles which
defaults to true. When set to false field names in the first line
are suppressed.
Example 10: Recordset Filters
Sometimes we want to pre-process all rows in a recordset before we use it.
For example, we want to ucwords all text in recordset.
include_once('adodb/rsfilter.inc.php');
include_once('adodb/adodb.inc.php');
// ucwords() every element in the recordset
function do_ucwords(&$arr,$rs)
{
foreach($arr as $k =gt; $v) {
$arr[$k] = ucwords($v);
}
}
$db = NewADOConnection('mysql');
$db->PConnect('server','user','pwd','db');
$rs = $db->Execute('select ... from table');
$rs = RSFilter($rs,'do_ucwords');
The RSFilter function takes 2 parameters, the recordset, and the name
of the filter function. It returns the processed recordset scrolled to
the first record. The filter function takes two parameters, the current
row as an array, and the recordset object. For future compatibility, you should
not use the original recordset object.
Example 11: Smart Transactions
The old way of doing transactions required you to use
$conn->BeginTrans();
$ok = $conn->Execute($sql);
if ($ok) $ok = $conn->Execute($sql2);
if (!$ok) $conn->RollbackTrans();
else $conn->CommitTrans();
This is very complicated for large projects because you have to track the error
status. Smart Transactions is much simpler. You start a smart transaction by calling
StartTrans():
$conn->StartTrans();
$conn->Execute($sql);
$conn->Execute($Sql2);
$conn->CompleteTrans();
CompleteTrans() detects when an SQL error occurs, and will Rollback/Commit as
appropriate. To specificly force a rollback even if no error occured, use FailTrans().
Note that the rollback is done in CompleteTrans(), and not in FailTrans().
$conn->StartTrans();
$conn->Execute($sql);
if (!CheckRecords()) $conn->FailTrans();
$conn->Execute($Sql2);
$conn->CompleteTrans();
You can also check if a transaction has failed, using HasFailedTrans(), which
returns true if FailTrans() was called, or there was an error in the SQL execution.
Make sure you call HasFailedTrans() before you call CompleteTrans(), as it is
only works between StartTrans/CompleteTrans.
Lastly, StartTrans/CompleteTrans is nestable, and only the outermost block
is executed. In contrast, BeginTrans/CommitTrans/RollbackTrans is NOT nestable.
$conn->StartTrans();
$conn->Execute($sql);
$conn->StartTrans(); # ignored
if (!CheckRecords()) $conn->FailTrans();
$conn->CompleteTrans(); # ignored
$conn->Execute($Sql2);
$conn->CompleteTrans();
Note: Savepoints are currently not supported.
Using Custom Error Handlers and PEAR_Error
ADOdb supports PHP5 exceptions. Just include adodb-exceptions.inc.php and you can now
catch exceptions on errors as they occur.
include("../adodb-exceptions.inc.php");
include("../adodb.inc.php");
try {
$db = NewADOConnection("oci8://scott:bad-password@mytns/");
} catch (exception $e) {
var_dump($e);
adodb_backtrace($e->gettrace());
}
ADOdb also provides two custom handlers which you can modify for your needs. The
first one is in the adodb-errorhandler.inc.php file. This makes use of
the standard PHP functions
to control what error messages types to display, and
which invokes the default PHP error handler.
Including the above file will cause trigger_error($errorstring,E_USER_ERROR)
to be called when
(a) Connect() or PConnect() fails, or
(b) a function that executes SQL statements such as Execute() or SelectLimit()
has an error.
(c) GenID() appears to go into an infinite loop.
The $errorstring is generated by ADOdb and will contain useful debugging information
similar to the error.log data generated below. This file adodb-errorhandler.inc.php
should be included before you create any ADOConnection objects.
If you define error_reporting(0), no errors will be passed to the error handler.
If you set error_reporting(E_ALL), all errors will be passed to the error handler.
You still need to use ini_set("display_errors", "0" or "1") to control
the display of errors.
<?php
error_reporting(E_ALL); # pass any error messages triggered to error handler
include('adodb-errorhandler.inc.php');
include('adodb.inc.php');
include('tohtml.inc.php');
$c = NewADOConnection('mysql');
$c->PConnect('localhost','root','','northwind');
$rs=$c->Execute('select * from productsz'); #invalid table productsz');
if ($rs) rs2html($rs);
?>
If you want to log the error message, you can do so by defining the following
optional constants ADODB_ERROR_LOG_TYPE and ADODB_ERROR_LOG_DEST. ADODB_ERROR_LOG_TYPE
is the error log message type (see
in the PHP manual). In this case we set it to 3, which means log to the file
defined by the constant ADODB_ERROR_LOG_DEST.
<?php
error_reporting(E_ALL); # report all errors
ini_set("display_errors", "0"); # but do not echo the errors
define('ADODB_ERROR_LOG_TYPE',3);
define('ADODB_ERROR_LOG_DEST','C:/errors.log');
include('adodb-errorhandler.inc.php');
include('adodb.inc.php');
include('tohtml.inc.php');
$c = NewADOConnection('mysql');
$c->PConnect('localhost','root','','northwind');
$rs=$c->Execute('select * from productsz'); ## invalid table productsz
if ($rs) rs2html($rs);
?>
The following message will be logged in the error.log file:
(2001-10-28 14:20:38) mysql error: [1146: Table 'northwind.productsz' doesn't exist] in
EXECUTE("select * from productsz")
PEAR_ERROR
The second error handler is adodb-errorpear.inc.php. This will create a
PEAR_Error derived object whenever an error occurs. The last PEAR_Error object
created can be retrieved using ADODB_Pear_Error().
<?php
include('adodb-errorpear.inc.php');
include('adodb.inc.php');
include('tohtml.inc.php');
$c = NewADOConnection('mysql');
$c->PConnect('localhost','root','','northwind');
$rs=$c->Execute('select * from productsz'); #invalid table productsz');
if ($rs) rs2html($rs);
else {
$e = ADODB_Pear_Error();
echo '<p>',$e->message,'</p>';
}
?>
You can use a PEAR_Error derived class by defining the constant ADODB_PEAR_ERROR_CLASS
before the adodb-errorpear.inc.php file is included. For easy debugging, you
can set the default error handler in the beginning of the PHP script to PEAR_ERROR_DIE,
which will cause an error message to be printed, then halt script execution:
include('PEAR.php');
PEAR::setErrorHandling('PEAR_ERROR_DIE');
Note that we do not explicitly return a PEAR_Error object to you when an error
occurs. We return false instead. You have to call ADODB_Pear_Error() to get
the last error or use the PEAR_ERROR_DIE technique.
MetaError and MetaErrMsg
If you need error messages that work across multiple databases, then use MetaError(), which returns a virtualized error number, based on PEAR DB's error number system, and MetaErrMsg().
Error Messages
Error messages are outputted using the static method ADOConnnection::outp($msg,$newline=true).
By default, it sends the messages to the client. You can override this to perform
error-logging.
Data Source Names
We now support connecting using PEAR style DSN's. A DSN is a connection string
of the form:
$dsn = "$driver://$username:$password@$hostname/$databasename";
An example:
$username = 'root';
$password = '';
$hostname = 'localhost';
$databasename = 'xphplens';
$driver = 'mysql';
$dsn = "$driver://$username:$password@$hostname/$databasename"
$db = NewADOConnection();
# DB::Connect($dsn) also works if you include 'adodb/adodb-pear.inc.php' at the top
$rs = $db->query('select firstname,lastname from adoxyz');
$cnt = 0;
while ($arr = $rs->fetchRow()) {
print_r($arr); print "<br>";
}
More info and connection examples on the DSN format.
PEAR Compatibility
We support DSN's (see above), and the following functions:
DB_Common
query - returns PEAR_Error on error
limitQuery - return PEAR_Error on error
prepare - does not return PEAR_Error on error
execute - does not return PEAR_Error on error
setFetchMode - supports ASSOC and ORDERED
errorNative
quote
nextID
disconnect
getOne
getAssoc
getRow
getCol
DB_Result
numRows - returns -1 if not supported
numCols
fetchInto - does not support passing of fetchmode
fetchRows - does not support passing of fetchmode
free
Caching of Recordsets
ADOdb now supports caching of recordsets using the CacheExecute( ), CachePageExecute(
) and CacheSelectLimit( ) functions. There are similar to the non-cache functions,
except that they take a new first parameter, $secs2cache.
An example:
include('adodb.inc.php'); # load code common to ADOdb
$ADODB_CACHE_DIR = '/usr/ADODB_cache';
$conn =ADONewConnection('mysql'); # create a connection
$conn->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
$sql = 'select CustomerName, CustomerID from customers';
$rs = $conn->CacheExecute(15,$sql);
The first parameter is the number of seconds to cache
the query. Subsequent calls to that query will used the cached version stored
in $ADODB_CACHE_DIR. To force a query to execute and flush the cache, call CacheExecute()
with the first parameter set to zero. Alternatively, use the CacheFlush($sql)
call.
For the sake of security, we recommend you set register_globals=off
in php.ini if you are using $ADODB_CACHE_DIR.
In ADOdb 1.80 onwards, the secs2cache parameter is optional in CacheSelectLimit()
and CacheExecute(). If you leave it out, it will use the $connection->cacheSecs
parameter, which defaults to 60 minutes.
$conn->Connect(...);
$conn->cacheSecs = 3600*24; # cache 24 hours
$rs = $conn->CacheExecute('select * from table');
Please note that magic_quotes_runtime should be turned off. , and do not change $ADODB_FETCH_MODE (or SetFetchMode)
as the cached recordset will use the $ADODB_FETCH_MODE set when the query was executed.
Pivot Tables
Since ADOdb 2.30, we support the generation of
SQL to create pivot tables, also known as cross-tabulations. For further explanation
read this DevShed . We assume that your database supports the SQL case-when expression.
In this example, we will use the Northwind database from Microsoft. In the
database, we have a products table, and we want to analyze this table by suppliers
versus product categories. We will place the suppliers on each row, and
pivot on categories. So from the table on the left, we generate the pivot-table
on the right:
Supplier
Category
supplier1
category1
supplier2
category1
supplier2
category2
-->
category1
category2
total
supplier1
1
0
1
supplier2
1
1
2
The following code will generate the SQL for a cross-tabulation:
# Query the main "product" table
# Set the rows to SupplierName
# and the columns to the values of Categories
# and define the joins to link to lookup tables
# "categories" and "suppliers"
#
include "adodb/pivottable.inc.php";
$sql = PivotTableSQL(
$gDB, # adodb connection
'products p ,categories c ,suppliers s', # tables
'SupplierName', # rows (multiple fields allowed)
'CategoryName', # column to pivot on
'p.CategoryID = c.CategoryID and s.SupplierID= p.SupplierID' # joins/where
);
This will generate the following SQL:
SELECT SupplierName,
SUM(CASE WHEN CategoryName='Beverages' THEN 1 ELSE 0 END) AS "Beverages",
SUM(CASE WHEN CategoryName='Condiments' THEN 1 ELSE 0 END) AS "Condiments",
SUM(CASE WHEN CategoryName='Confections' THEN 1 ELSE 0 END) AS "Confections",
SUM(CASE WHEN CategoryName='Dairy Products' THEN 1 ELSE 0 END) AS "Dairy
Products",
SUM(CASE WHEN CategoryName='Grains/Cereals' THEN 1 ELSE 0 END) AS "Grains/Cereals",
SUM(CASE WHEN CategoryName='Meat/Poultry' THEN 1 ELSE 0 END) AS "Meat/Poultry",
SUM(CASE WHEN CategoryName='Produce' THEN 1 ELSE 0 END) AS "Produce",
SUM(CASE WHEN CategoryName='Seafood' THEN 1 ELSE 0 END) AS "Seafood",
SUM(1) as Total
FROM products p ,categories c ,suppliers s WHERE p.CategoryID = c.CategoryID
and s.SupplierID= p.SupplierID
GROUP BY SupplierName
You can also pivot on numerical columns and generate totals
by using ranges. This code was revised in ADODB 2.41
and is not backward compatible. The second example shows this:
$sql = PivotTableSQL(
$gDB, # adodb connection
'products p ,categories c ,suppliers s', # tables
'SupplierName', # rows (multiple fields allowed)
array( # column ranges
' 0 ' =gt; 'UnitsInStock <= 0',
"1 to 5" =gt; '0 < UnitsInStock and UnitsInStock <= 5',
"6 to 10" =gt; '5 < UnitsInStock and UnitsInStock <= 10',
"11 to 15" =gt; '10 < UnitsInStock and UnitsInStock <= 15',
"16+" =gt; '15 < UnitsInStock'
),
' p.CategoryID = c.CategoryID and s.SupplierID= p.SupplierID', # joins/where
'UnitsInStock', # sum this field
'Sum ' # sum label prefix
);
Which generates:
SELECT SupplierName,
SUM(CASE WHEN UnitsInStock <= 0 THEN UnitsInStock ELSE 0 END) AS "Sum
0 ",
SUM(CASE WHEN 0 < UnitsInStock and UnitsInStock <= 5 THEN UnitsInStock
ELSE 0 END) AS "Sum 1 to 5",
SUM(CASE WHEN 5 < UnitsInStock and UnitsInStock <= 10 THEN UnitsInStock
ELSE 0 END) AS "Sum 6 to 10",
SUM(CASE WHEN 10 < UnitsInStock and UnitsInStock <= 15 THEN UnitsInStock
ELSE 0 END) AS "Sum 11 to 15",
SUM(CASE WHEN 15 < UnitsInStock THEN UnitsInStock ELSE 0 END) AS "Sum
16+",
SUM(UnitsInStock) AS "Sum UnitsInStock",
SUM(1) as Total,
FROM products p ,categories c ,suppliers s WHERE p.CategoryID = c.CategoryID
and s.SupplierID= p.SupplierID
GROUP BY SupplierName
Class Reference
Function parameters with [ ] around them are optional.
Global Variables
$ADODB_COUNTRECS
If the database driver API does not support counting the number of records
returned in a SELECT statement, the function RecordCount() is emulated when
the global variable $ADODB_COUNTRECS is set to true, which is the default.
We emulate this by buffering the records, which can take up large amounts
of memory for big recordsets. Set this variable to false for the best performance.
This variable is checked every time a query is executed, so you can selectively
choose which recordsets to count.
$ADODB_CACHE_DIR
If you are using recordset caching, this is the directory to save your recordsets
in. Define this before you call any caching functions such as CacheExecute(
). We recommend setting register_globals=off in php.ini if you use this
feature for security reasons.
If you are using Unix and apache, you might need to set your cache directory
permissions to something similar to the following:
chown -R apache /path/to/adodb/cache
chgrp -R apache /path/to/adodb/cache
$ADODB_ANSI_PADDING_OFF
Determines whether to right trim CHAR fields (and also VARCHAR for ibase/firebird).
Set to true to trim. Default is false. Currently works for oci8po, ibase and firebird
drivers. Added in ADOdb 4.01.
$ADODB_LANG
Determines the language used in MetaErrorMsg(). The default is 'en', for English.
To find out what languages are supported, see the files
in adodb/lang/adodb-$lang.inc.php, where $lang is the supported langauge.
$ADODB_FETCH_MODE
This is a global variable that determines how arrays are retrieved by recordsets.
The recordset saves this value on creation (eg. in Execute( ) or SelectLimit(
)), and any subsequent changes to $ADODB_FETCH_MODE have no affect on existing
recordsets, only on recordsets created in the future.
The following constants are defined:
define('ADODB_FETCH_DEFAULT',0);
define('ADODB_FETCH_NUM',1);
define('ADODB_FETCH_ASSOC',2);
define('ADODB_FETCH_BOTH',3);
An example:
$ADODB_FETCH_MODE = ADODB_FETCH_NUM;
$rs1 = $db->Execute('select * from table');
$ADODB_FETCH_MODE = ADODB_FETCH_ASSOC;
$rs2 = $db->Execute('select * from table');
print_r($rs1->fields); # shows array([0]=gt;'v0',[1] =gt;'v1')
print_r($rs2->fields); # shows array(['col1']=gt;'v0',['col2'] =gt;'v1')
As you can see in the above example, both recordsets store and use different
fetch modes based on the $ADODB_FETCH_MODE setting when the recordset was
created by Execute().
If no fetch mode is predefined, the fetch mode defaults to ADODB_FETCH_DEFAULT.
The behaviour of this default mode varies from driver to driver, so do not
rely on ADODB_FETCH_DEFAULT. For portability, we recommend sticking to ADODB_FETCH_NUM
or ADODB_FETCH_ASSOC. Many drivers do not support ADODB_FETCH_BOTH.
SetFetchMode Function
If you have multiple connection objects, and want to have different fetch modes for each
connection, then use SetFetchMode.
Once this function is called for a connection object, that connection object
will ignore the global variable $ADODB_FETCH_MODE and will use the internal
fetchMode property exclusively.
$db->SetFetchMode(ADODB_FETCH_NUM);
$rs1 = $db->Execute('select * from table');
$db->SetFetchMode(ADODB_FETCH_ASSOC);
$rs2 = $db->Execute('select * from table');
print_r($rs1->fields); # shows array([0]=gt;'v0',[1] =gt;'v1')
print_r($rs2->fields); # shows array(['col1']=gt;'v0',['col2'] =gt;'v1')
To retrieve the previous fetch mode, you can use check the $db->fetchMode
property, or use the return value of SetFetchMode( ).
You can control the associative fetch case for certain drivers which behave
differently. For the sybase, oci8po, mssql, odbc and ibase drivers and all
drivers derived from them, ADODB_ASSOC_CASE will by default generate recordsets
where the field name keys are lower-cased. Use the constant ADODB_ASSOC_CASE
to change the case of the keys. There are 3 possible values:
0 = assoc lowercase field names. $rs->fields['orderid']
1 = assoc uppercase field names. $rs->fields['ORDERID']
2 = use native-case field names. $rs->fields['OrderID'] -- this is the
default since ADOdb 2.90
To use it, declare it before you incldue adodb.inc.php.
define('ADODB_ASSOC_CASE', 2); # use native-case for ADODB_FETCH_ASSOC
include('adodb.inc.php');
$ADODB_FORCE_TYPE
See the GetUpdateSQL tutorial.
$ADODB_QUOTE_FIELDNAMES
Auto-quotes field names when using AutoExecute() when set to true.
ADOConnection
Object that performs the connection to the database, executes SQL statements
and has a set of utility functions for standardising the format of SQL statements
for issues such as concatenation and date formats.
ADOConnection Fields
databaseType: Name of the database system we are connecting to. Eg.
odbc or mssql or mysql.
dataProvider: The underlying mechanism used to connect to the database.
Normally set to native, unless using odbc or ado.
host: Name of server or data source name (DSN) to connect to.
database: Name of the database or to connect to. If ado is used, it
will hold the ado data provider.
user: Login id to connect to database. Password is not saved for security
reasons.
raiseErrorFn: Allows you to define an error handling function. See adodb-errorhandler.inc.php
for an example.
debug: Set to true to make debug statements to appear.
concat_operator: Set to '+' or '||' normally. The operator used to concatenate
strings in SQL. Used by the Concat function.
fmtDate: The format used by the DBDate
function to send dates to the database. is '#Y-m-d#' for Microsoft Access,
and ''Y-m-d'' for MySQL.
fmtTimeStamp: The format used by the DBTimeStamp
function to send timestamps to the database.
true: The value used to represent true.Eg. '.T.'. for Foxpro, '1' for
Microsoft SQL.
false: The value used to represent false. Eg. '.F.'. for Foxpro, '0'
for Microsoft SQL.
replaceQuote: The string used to escape quotes. Eg. double single-quotes
for Microsoft SQL, and backslash-quote for MySQL. Used by qstr.
autoCommit: indicates whether automatic commit is enabled. Default is
true.
charSet: set the default charset to use. Currently only interbase/firebird supports
this.
dialect: set the default sql dialect to use. Currently only interbase/firebird
supports this.
role: set the role. Currently only interbase/firebird
supports this.
metaTablesSQL: SQL statement to return a list of available tables. Eg.
SHOW TABLES in MySQL.
genID: The latest id generated by GenID() if supported by the database.
cacheSecs: The number of seconds to cache recordsets if CacheExecute()
or CacheSelectLimit() omit the $secs2cache parameter. Defaults to 60 minutes.
sysDate: String that holds the name of the database function to call
to get the current date. Useful for inserts and updates.
sysTimeStamp: String that holds the name of the database function to
call to get the current timestamp/datetime value.
leftOuter: String that holds operator for left outer join, if known.
Otherwise set to false.
rightOuter: String that holds operator for left outer join, if known.
Otherwise set to false.
ansiOuter: Boolean that if true indicates that ANSI style outer joins
are permitted. Eg. select * from table1 left join table2 on p1=p2.
connectSID: Boolean that indicates whether to treat the $database parameter
in connects as the SID for the oci8 driver. Defaults to false. Useful for
Oracle 8.0.5 and earlier.
autoRollback: Persistent connections are auto-rollbacked in PConnect(
) if this is set to true. Default is false.
ADOConnection Main Functions
ADOConnection( )
Constructor function. Do not call this directly. Use ADONewConnection( ) instead.
Connect($host,[$user],[$password],[$database])
Non-persistent connect to data source or server $host, using userid
$user and password $password. If the server supports multiple
databases, connect to database $database.
Returns true/false depending on connection success. Since 4.23, null is returned if the extension is not loaded.
ADO Note: If you are using a Microsoft ADO and not OLEDB, you can set the $database
parameter to the OLEDB data provider you are using.
PostgreSQL: An alternative way of connecting to the database is to pass the
standard PostgreSQL connection string in the first parameter $host, and the
other parameters will be ignored.
For Oracle and Oci8, there are two ways to connect. First is to use the TNS
name defined in your local tnsnames.ora (or ONAMES or HOSTNAMES). Place the
name in the $database field, and set the $host field to false. Alternatively,
set $host to the server, and $database to the database SID, this bypassed
tnsnames.ora.
Examples:
# $oraname in tnsnames.ora/ONAMES/HOSTNAMES
$conn->Connect(false, 'scott', 'tiger', $oraname);
$conn->Connect('server:1521', 'scott', 'tiger', 'ServiceName'); # bypass tnsnames.ora
There are many examples of connecting to a database.
See Connection Examples for many examples.
PConnect($host,[$user],[$password],[$database])
Persistent connect to data source or server $host, using userid $user
and password $password. If the server supports multiple databases,
connect to database $database.
We now perform a rollback on persistent connection for selected databases since
2.21, as advised in the PHP manual. See change log or source code for which
databases are affected.
Returns true/false depending on connection. Since 4.23, 0 is returned if the extension is not loaded.
See Connect( ) above for more info.
Since ADOdb 2.21, we also support autoRollback. If you set:
$conn =NewADOConnection('mysql');
$conn->autoRollback = true; # default is false
$conn->PConnect(...); # rollback here
Then when doing a persistent connection with PConnect( ), ADOdb will
perform a rollback first. This is because it is documented that PHP is
not guaranteed to rollback existing failed transactions when
persistent connections are used. This is implemented in Oracle,
MySQL, PgSQL, MSSQL, ODBC currently.
Since ADOdb 3.11, you can force non-persistent
connections even if PConnect is called by defining the constant
ADODB_NEVER_PERSIST before you call PConnect.
Since 4.23, null is returned if the extension is not loaded.
NConnect($host,[$user],[$password],[$database])
Always force a new connection. In contrast, PHP sometimes reuses connections
when you use Connect() or PConnect(). Currently works only on mysql (PHP 4.3.0
or later), postgresql and oci8-derived drivers. For other drivers, NConnect() works like
Connect().
Returns true if connected to database. Added in 4.53.
Execute SQL statement $sql and return derived class of ADORecordSet
if successful. Note that a record set is always returned on success, even
if we are executing an insert or update statement. You can also pass in $sql a statement prepared
in Prepare().
Returns derived class of ADORecordSet. Eg. if connecting via mysql, then ADORecordSet_mysql
would be returned. False is returned if there was an error in executing the
sql.
The $inputarr parameter can be used for binding variables to parameters. Below
is an Oracle example:
$conn->Execute("SELECT * FROM TABLE WHERE COND=:val", array('val'=gt; $val));
Another example, using ODBC,which uses the ? convention:
$conn->Execute("SELECT * FROM TABLE WHERE COND=?", array($val));
Binding variables
Variable binding speeds the compilation and caching of SQL statements, leading
to higher performance. Currently Oracle, Interbase and ODBC supports variable binding.
Interbase/ODBC style ? binding is emulated in databases that do not support binding.
Note that you do not have to quote strings if you use binding.
Variable binding in the odbc, interbase and oci8po drivers.
$rs = $db->Execute('select * from table where val=?', array('10'));
Variable binding in the oci8 driver:
$rs = $db->Execute('select name from table where val=:key',
array('key' =gt; 10));
Bulk binding
Since ADOdb 3.80, we support bulk binding in Execute(), in which you pass in a 2-dimensional array to
be bound to an INSERT/UPDATE or DELETE statement.
$arr = array(
array('Ahmad',32),
array('Zulkifli', 24),
array('Rosnah', 21)
);
$ok = $db->Execute('insert into table (name,age) values (?,?)',$arr);
This provides very high performance as the SQL statement is prepared first.
The prepared statement is executed repeatedly for each array row until all rows are completed,
or until the first error. Very useful for importing data.
CacheExecute([$secs2cache,]$sql,$inputarr=false)
Similar to Execute, except that the recordset is cached for $secs2cache seconds
in the $ADODB_CACHE_DIR directory, and $inputarr only accepts 1-dimensional arrays.
If CacheExecute() is called again with the same $sql, $inputarr,
and also the same database, same userid, and the cached recordset
has not expired, the cached recordset is returned.
include('adodb.inc.php');
include('tohtml.inc.php');
$ADODB_CACHE_DIR = '/usr/local/ADOdbcache';
$conn =ADONewConnection('mysql');
$conn->PConnect('localhost','userid','password','database');
$rs = $conn->CacheExecute(15, 'select * from table'); # cache 15 secs
rs2html($rs); /* recordset to html table */
Alternatively, since ADOdb 1.80, the $secs2cache parameter is optional:
$conn->Connect(...);
$conn->cacheSecs = 3600*24; // cache 24 hours
$rs = $conn->CacheExecute('select * from table');
If $secs2cache is omitted, we use the value
in $connection->cacheSecs (default is 3600 seconds, or 1 hour). Use CacheExecute()
only with SELECT statements.
Performance note: I have done some benchmarks and found that they vary so greatly
that it's better to talk about when caching is of benefit. When your database
server is much slower than your Web server or the database is very
overloaded then ADOdb's caching is good because it reduces the load on
your database server. If your database server is lightly loaded or much faster
than your Web server, then caching could actually reduce performance.
ExecuteCursor($sql,$cursorName='rs',$parameters=false)
Execute an Oracle stored procedure, and returns an Oracle REF cursor variable as
a regular ADOdb recordset. Does not work with any other database except oci8.
Thanks to Robert Tuttle for the design.
$db = ADONewConnection("oci8");
$db->Connect("foo.com:1521", "uid", "pwd", "FOO");
$rs = $db->ExecuteCursor("begin :cursorvar := getdata(:param1); end;",
'cursorvar',
array('param1'=gt;10));
# $rs is now just like any other ADOdb recordset object
rs2html($rs);
ExecuteCursor() is a helper function that does the following internally:
$stmt = $db->Prepare("begin :cursorvar := getdata(:param1); end;", true);
$db->Parameter($stmt, $cur, 'cursorvar', false, -1, OCI_B_CURSOR);
$rs = $db->Execute($stmt,$bindarr);
ExecuteCursor only accepts 1 out parameter. So if you have 2 out parameters, use:
$vv = 'A%';
$stmt = $db->PrepareSP("BEGIN list_tabs(:crsr,:tt); END;");
$db->OutParameter($stmt, $cur, 'crsr', -1, OCI_B_CURSOR);
$db->OutParameter($stmt, $vv, 'tt', 32); # return varchar(32)
$arr = $db->GetArray($stmt);
print_r($arr);
echo " val = $vv"; ## outputs 'TEST'
for the following PL/SQL:
TYPE TabType IS REF CURSOR RETURN TAB%ROWTYPE;
PROCEDURE list_tabs(tabcursor IN OUT TabType,tablenames IN OUT VARCHAR) IS
BEGIN
OPEN tabcursor FOR SELECT * FROM TAB WHERE tname LIKE tablenames;
tablenames := 'TEST';
END list_tabs;
SelectLimit($sql,$numrows=-1,$offset=-1,$inputarr=false)
Returns a recordset if successful. Returns false otherwise. Performs a select
statement, simulating PostgreSQL's SELECT statement, LIMIT $numrows OFFSET
$offset clause.
In PostgreSQL, SELECT * FROM TABLE LIMIT 3 will return the first 3 records
only. The equivalent is $connection->SelectLimit('SELECT * FROM TABLE',3).
This functionality is simulated for databases that do not possess this feature.
And SELECT * FROM TABLE LIMIT 3 OFFSET 2 will return records 3, 4 and 5 (eg.
after record 2, return 3 rows). The equivalent in ADOdb is $connection->SelectLimit('SELECT
* FROM TABLE',3,2).
Note that this is the opposite of MySQL's LIMIT clause. You can also
set $connection->SelectLimit('SELECT * FROM TABLE',-1,10) to
get rows 11 to the last row.
The last parameter $inputarr is for databases that support variable binding
such as Oracle oci8. This substantially reduces SQL compilation overhead.
Below is an Oracle example:
$conn->SelectLimit("SELECT * FROM TABLE WHERE COND=:val", 100,-1,array('val'=gt; $val));
The oci8po driver (oracle portable driver) uses the more standard bind variable
of ?:
$conn->SelectLimit("SELECT * FROM TABLE WHERE COND=?", 100,-1,array('val'=gt; $val));
Ron Wilson reports that SelectLimit does not work with UNIONs.
CacheSelectLimit([$secs2cache,] $sql, $numrows=-1,$offset=-1,$inputarr=false)
Similar to SelectLimit, except that the recordset returned is cached for $secs2cache
seconds in the $ADODB_CACHE_DIR directory.
Since 1.80, $secs2cache has been optional, and you can define the caching time
in $connection->cacheSecs.
$conn->Connect(...);
$conn->cacheSecs = 3600*24; // cache 24 hours
$rs = $conn->CacheSelectLimit('select * from table',10);
CacheFlush($sql=false,$inputarr=false)
Flush (delete) any cached recordsets for the SQL statement $sql in $ADODB_CACHE_DIR.
If no parameter is passed in, then all adodb_*.cache files are deleted.
CacheSelectLimit() rewrites the SQL query, so you won't be able to pass the SQL to CacheFlush. In this case,
to flush the cached SQL recordset returned by CacheSelectLimit(), set $secs2cache to -1:
$db->CacheSelectLimit(-1, $sql, $nrows);
If you want to flush all cached recordsets manually, execute the following
PHP code (works only under Unix):
system("rm -f `find ".$ADODB_CACHE_DIR." -name
adodb_*.cache`");
For general cleanup of all expired files, you should use
on Unix, or at.exe on Windows, and a shell script similar to the following:
#------------------------------------------------------
# This particular example deletes files in the TMPPATH
# directory with the string ".cache" in their name that
# are more than 7 days old.
#------------------------------------------------------
AGED=7
find ${TMPPATH} -mtime +$AGED | grep "\.cache" | xargs rm -f
Returns a virtualized error number, based on PEAR DB's error number system. You might
need to include adodb-error.inc.php before you call this function. The parameter $errno
is the native error number you want to convert. If you do not pass any parameter, MetaError
will call ErrorNo() for you and convert it. If the error number cannot be virtualized, MetaError
will return -1 (DB_ERROR).
Pass the error number returned by MetaError() for the equivalent textual error message.
Returns the last status or error message. The error message is reset after every
call to Execute().
This can return a string even if
no error occurs. In general you do not need to call this function unless an
ADOdb function returns false on an error.
Note: If debug is enabled, the SQL error message is always displayed
when the Execute function is called.
Returns the last error number. The error number is reset after every call to Execute().
If 0 is returned, no error occurred.
Note that old versions of PHP (pre 4.0.6) do
not support error number for ODBC. In general you do not need to call this
function unless an ADOdb function returns false on an error.
IgnoreErrors($saveErrHandlers)
Allows you to ignore errors so that StartTrans()/CompleteTrans() is not affected, nor is the default error handler called if an error occurs.
Useful when you want to check if a field or table exists in a database without invoking an error if it does not exist.
Usage:
$saveErrHandlers = $conn->IgnoreErrors();
$rs = $conn->Execute("select field from some_table_that_might_not_exist");
$conn->IgnoreErrors($saveErrHandlers);
Warning: do not call StartTrans()/CompleteTrans() inside a code block that is using IgnoreErrors().
Sets the current fetch mode for the connection and stores
it in $db->fetchMode. Legal modes are ADODB_FETCH_ASSOC and ADODB_FETCH_NUM.
For more info, see $ADODB_FETCH_MODE.
Returns the previous fetch mode, which could be false
if SetFetchMode( ) has not been called before.
CreateSequence($seqName = 'adodbseq',$startID=1)
Create a sequence. The next time GenID( ) is called, the value returned will
be $startID. Added in 2.60.
DropSequence($seqName = 'adodbseq')
Delete a sequence. Added in 2.60.
GenID($seqName = 'adodbseq',$startID=1)
Generate a sequence number . Works for interbase,
mysql, postgresql, oci8, oci8po, mssql, ODBC based (access,vfp,db2,etc) drivers
currently. Uses $seqName as the name of the sequence. GenID() will automatically
create the sequence for you if it does not exist (provided the userid has
permission to do so). Otherwise you will have to create the sequence yourself.
If your database driver emulates sequences, the name of the table is the sequence
name. The table has one column, "id" which should be of type integer, or if
you need something larger - numeric(16).
For ODBC and databases that do not support sequences natively (eg mssql, mysql),
we create a table for each sequence. If the sequence has not been defined
earlier, it is created with the starting value set in $startID.
Note that the mssql driver's GenID() before 1.90 used to generate 16 byte GUID's.
UpdateBlob($table,$column,$val,$where)
Allows you to store a blob (in $val) into $table into $column in a row at $where.
Usage:
# for oracle
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, empty_blob())');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
# non oracle databases
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
Returns true if succesful, false otherwise. Supported by MySQL, PostgreSQL,
Oci8, Oci8po and Interbase drivers. Other drivers might work, depending on
the state of development.
Note that when an Interbase blob is retrieved using SELECT, it still needs
to be decoded using $connection->DecodeBlob($blob); to derive the original
value in versions of PHP before 4.1.0.
For PostgreSQL, you can store your blob using blob oid's or as a bytea field.
You can use bytea fields but not blob oid's currently with UpdateBlob( ).
Conversely UpdateBlobFile( ) supports oid's, but not bytea data.
If you do not pass in an oid, then UpdateBlob() assumes that you are storing
in bytea fields.
If you do not have any blob fields, you can improve you can improve general SQL query performance by disabling blob handling with $connection->disableBlobs = true.
UpdateClob($table,$column,$val,$where)
Allows you to store a clob (in $val) into $table into $column in a row at $where.
Similar to UpdateBlob (see above), but for Character Large OBjects.
Usage:
# for oracle
$conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, empty_clob())');
$conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
# non oracle databases
$conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, null)');
$conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
UpdateBlobFile($table,$column,$path,$where,$blobtype='BLOB')
Similar to UpdateBlob, except that we pass in a file path to where the blob
resides.
For PostgreSQL, if you are using blob oid's, use this interface. This interface
does not support bytea fields.
Returns true if successful, false otherwise.
Some databases require blob's to be encoded manually before upload. Note if
you use UpdateBlob( ) or UpdateBlobFile( ) the conversion is done automatically
for you and you do not have to call this function. For PostgreSQL, currently,
BlobEncode() can only be used for bytea fields.
Returns the encoded blob value.
Note that there is a connection property called blobEncodeType which
has 3 legal values:
false - no need to perform encoding or decoding.
'I' - blob encoding required, and returned encoded blob is a numeric value
(no need to quote).
'C' - blob encoding required, and returned encoded blob is a character value
(requires quoting).
This is purely for documentation purposes, so that programs that accept multiple
database drivers know what is the right thing to do when processing blobs.
BlobDecode($blob, $maxblobsize = false)
Some databases require blob's to be decoded manually after doing a select statement.
If the database does not require decoding, then this function will return
the blob unchanged. Currently BlobDecode is only required for one database,
PostgreSQL, and only if you are using blob oid's (if you are using bytea fields,
we auto-decode for you). The default maxblobsize is set in $connection->maxblobsize, which
is set to 256K in adodb 4.54.
In ADOdb 4.54 and later, the blob is the return value. In earlier versions, the blob data is sent to stdout.
$rs = $db->Execute("select bloboid from postgres_table where id=$key");
$blob = $db->BlobDecode( reset($rs->fields) );
Replace($table, $arrFields, $keyCols,$autoQuote=false)
Try to update a record, and if the record is not found, an insert statement
is generated and executed. Returns 0 on failure, 1 if update statement worked,
2 if no record was found and the insert was executed successfully. This differs
from MySQL's replace which deletes the record and inserts a new record. This
also means you cannot update the primary key. The only exception to this is
Interbase and its derivitives, which uses delete and insert because of some
Interbase API limitations.
The parameters are $table which is the table name, the $arrFields which is an
associative array where the keys are the field names, and $keyCols is the name
of the primary key, or an array of field names if it is a compound key. If
$autoQuote is set to true, then Replace() will quote all values that are non-numeric;
auto-quoting will not quote nulls. Note that auto-quoting will not work if
you use SQL functions or operators.
Examples:
# single field primary key
$ret = $db->Replace('atable',
array('id'=gt;1000,'firstname'=gt;'Harun','lastname'=gt;'Al-Rashid'),
'id',$autoquote = true);
# generates UPDATE atable SET firstname='Harun',lastname='Al-Rashid' WHERE id=1000
# or INSERT INTO atable (id,firstname,lastname) VALUES (1000,'Harun','Al-Rashid')
# compound key
$ret = $db->Replace('atable2',
array('firstname'=gt;'Harun','lastname'=gt;'Al-Rashid', 'age' =gt; 33, 'birthday' =gt; 'null'),
array('lastname','firstname'),
$autoquote = true);
# no auto-quoting
$ret = $db->Replace('atable2',
array('firstname'=gt;"'Harun'",'lastname'=gt;"'Al-Rashid'", 'age' =gt; 'null'),
array('lastname','firstname'));
AutoExecute($table, $arrFields, $mode, $where=false, $forceUpdate=true,$magicq=false)
Since ADOdb 4.56, you can automatically generate and execute INSERTs and UPDATEs on a given table with this
function, which is a wrapper for GetInsertSQL() and GetUpdateSQL().
AutoExecute() inserts or updates $table given an array of $arrFields, where the keys are the field names and the array values are the
field values to store. Note that there is some overhead because the table is first queried to extract key information
before the SQL is generated. We generate an INSERT or UPDATE based on $mode (see below).
Legal values for $mode are
- 'INSERT' or 1 or DB_AUTOQUERY_INSERT
- 'UPDATE' or 2 or DB_AUTOQUERY_UPDATE
You have to define the constants DB_AUTOQUERY_UPDATE and DB_AUTOQUERY_INSERT yourself or include adodb-pear.inc.php.
The $where clause is required if $mode == 'UPDATE'. If $forceUpdate=false then we will query the
database first and check if the field value returned by the query matches the current field value; only if they differ do we update that field.
Returns true on success, false on error.
An example of its use is:
$record["firstName"] = "Carol";
$record["lasTname"] = "Smith";
$conn->AutoExecute($table,$record,'INSERT');
# executes "INSERT INTO $table (firstName,lasTname) values ('Carol',Smith')";
$record["firstName"] = "Carol";
$record["lasTname"] = "Jones";
$conn->AutoExecute($table,$record,'UPDATE', "lastname like 'Sm%'");
# executes "UPDATE $table SET firstName='Carol',lasTname='Jones' WHERE lastname like 'Sm%'";
Note: One of the strengths of ADOdb's AutoExecute() is that only valid field names for $table are updated. If $arrFields
contains keys that are invalid field names for $table, they are ignored. There is some overhead in doing this as we have to
query the database to get the field names, but given that you are not directly coding the SQL yourself, you probably aren't interested in
speed at all, but convenience.
Since 4.62, the table name to be used can be overridden by setting $rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is called.
Since 4.94, setting the global variable $ADODB_QUOTE_FIELDNAMES to true will force field names to be auto-quoted in AutoExecute(), GetInsertSQL() and GetUpdateSQL().
GetUpdateSQL(&$rs, $arrFields, $forceUpdate=false,$magicq=false, $force=null)
Generate SQL to update a table given a recordset $rs, and the modified fields
of the array $arrFields (which must be an associative array holding the column
names and the new values) are compared with the current recordset. If $forceUpdate
is true, then we also generate the SQL even if $arrFields is identical to
$rs->fields. Requires the recordset to be associative. $magicq is used
to indicate whether magic quotes are enabled (see qstr()). The field names in the array
are case-insensitive.
Since 4.52, we allow you to pass the $force type parameter, and this overrides the $ADODB_FORCE_TYPE
global variable.
Since 4.62, the table name to be used can be overridden by setting $rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is called.
GetInsertSQL(&$rs, $arrFields,$magicq=false,$force_type=false)
Generate SQL to insert into a table given a recordset $rs. Requires the query
to be associative. $magicq is used to indicate whether magic quotes are enabled
(for qstr()). The field names in the array are case-insensitive.
Since 2.42, you can pass a table name instead of a recordset into
GetInsertSQL (in $rs), and it will generate an insert statement for that table.
Since 4.52, we allow you to pass the $force_type parameter, and this overrides the $ADODB_FORCE_TYPE
global variable.
Since 4.62, the table name to be used can be overridden by setting $rs->tableName before AutoExecute(), GetInsertSQL() or GetUpdateSQL() is called.
PageExecute($sql, $nrows, $page, $inputarr=false)
Used for pagination of recordset. $page is 1-based. See Example
8.
CachePageExecute($secs2cache,
$sql, $nrows, $page, $inputarr=false)
Used for pagination of recordset. $page is 1-based. See
Example 8. Caching version of PageExecute.
Close the database connection. PHP4 proudly states that we no longer have to
clean up at the end of the connection because the reference counting mechanism
of PHP4 will automatically clean up for us.
Start a monitored transaction. As SQL statements are executed, ADOdb will monitor
for SQL errors, and if any are detected, when CompleteTrans() is called, we auto-rollback.
To understand why StartTrans() is superior to BeginTrans(),
let us examine a few ways of using BeginTrans().
The following is the wrong way to use transactions:
$DB->BeginTrans();
$DB->Execute("update table1 set val=$val1 where id=$id");
$DB->Execute("update table2 set val=$val2 where id=$id");
$DB->CommitTrans();
because you perform no error checking. It is possible to update table1 and
for the update on table2 to fail. Here is a better way:
$DB->BeginTrans();
$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
if ($ok) $DB->CommitTrans();
else $DB->RollbackTrans();
Another way is (since ADOdb 2.0):
$DB->BeginTrans();
$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
$DB->CommitTrans($ok);
Now it is a headache monitoring $ok all over the place. StartTrans() is an
improvement because it monitors all SQL errors for you. This is particularly
useful if you are calling black-box functions in which SQL queries might be executed.
Also all BeginTrans, CommitTrans and RollbackTrans calls inside a StartTrans block
will be disabled, so even if the black box function does a commit, it will be ignored.
$DB->StartTrans();
CallBlackBox();
$DB->Execute("update table1 set val=$val1 where id=$id");
$DB->Execute("update table2 set val=$val2 where id=$id");
$DB->CompleteTrans();
Note that a StartTrans blocks are nestable, the inner blocks are ignored.
CompleteTrans($autoComplete=true)
Complete a transaction called with StartTrans(). This function monitors
for SQL errors, and will commit if no errors have occured, otherwise it will rollback.
Returns true on commit, false on rollback. If the parameter $autoComplete is true
monitor sql errors and commit and rollback as appropriate. Set $autoComplete to false
to force rollback even if no SQL error detected.
Fail a transaction started with StartTrans(). The rollback will only occur when
CompleteTrans() is called.
Check whether smart transaction has failed,
eg. returns true if there was an error in SQL execution or FailTrans() was called.
If not within smart transaction, returns false.
Begin a transaction. Turns off autoCommit. Returns true if successful. Some
databases will always return false if transaction support is not available.
Any open transactions will be rolled back when the connection is closed. Among the
databases that support transactions are Oracle, PostgreSQL, Interbase, MSSQL, certain
versions of MySQL, DB2, Informix, Sybase, etc.
Note that StartTrans() and CompleteTrans() is a superior method of
handling transactions, available since ADOdb 3.40. For a explanation, see the StartTrans() documentation.
You can also use the ADOdb error handler to die
and rollback your transactions for you transparently. Some buggy database extensions
are known to commit all outstanding tranasactions, so you might want to explicitly
do a $DB->RollbackTrans() in your error handler for safety.
Detecting Transactions
Since ADOdb 2.50, you are able to detect when you are inside a transaction. Check
that $connection->transCnt > 0. This variable is incremented whenever BeginTrans() is called,
and decremented whenever RollbackTrans() or CommitTrans() is called.
End a transaction successfully. Returns true if successful. If the database
does not support transactions, will return true also as data is always committed.
If you pass the parameter $ok=false, the data is rolled back. See example in
BeginTrans().
End a transaction, rollback all changes. Returns true if successful. If the
database does not support transactions, will return false as data is never rollbacked.
SetTransactionMode allows you to pass in the transaction mode to use for all subsequent transactions.
Note: if you have persistent connections and using mssql or mysql, you might have to explicitly reset your transaction mode at the beginning of each page request.
This is only supported in postgresql, mssql, mysql with InnoDB and oci8 currently. For example:
$db->SetTransactionMode("SERIALIZABLE");
$db->BeginTrans();
$db->Execute(...); $db->Execute(...);
$db->CommiTrans();
$db->SetTransactionMode(""); // restore to default
$db->StartTrans();
$db->Execute(...); $db->Execute(...);
$db->CompleteTrans();
Supported values to pass in:
- READ UNCOMMITTED (allows dirty reads, but fastest)
- READ COMMITTED (default postgres, mssql and oci8)
- REPEATABLE READ (default mysql)
- SERIALIZABLE (slowest and most restrictive)
You can also pass in database specific values such as 'SNAPSHOT' for mssql or 'READ ONLY' for oci8/postgres.
See transaction levels for ,
.
GetAssoc($sql,$inputarr=false,$force_array=false,$first2cols=false)
Returns an associative array for the given query $sql with optional bind parameters
in $inputarr. If the number of columns returned is greater to two, a 2-dimensional
array is returned, with the first column of the recordset becomes the keys
to the rest of the rows. If the columns is equal to two, a 1-dimensional array
is created, where the the keys directly map to the values (unless $force_array
is set to true, when an array is created for each value).
We have the following data in a recordset:
row1: Apple, Fruit, Edible
row2: Cactus, Plant, Inedible
row3: Rose, Flower, Edible
GetAssoc will generate the following 2-dimensional associative
array:
Apple =gt; array[Fruit, Edible]
Cactus =gt; array[Plant, Inedible]
Rose =gt; array[Flower,Edible]
If the dataset is:
row1: Apple, Fruit
row2: Cactus, Plant
row3: Rose, Flower
GetAssoc will generate the following 1-dimensional associative
array (with $force_array==false):
Apple =gt; Fruit
Cactus=gt;Plant
Rose=gt;Flower
The function returns:
The associative array, or false if an error occurs.
CacheGetAssoc([$secs2cache,] $sql,$inputarr=false,$force_array=false,$first2cols=false)
Caching version of GetAssoc function above.
Executes the SQL and returns the first field of the first row. The recordset
and remaining rows are discarded for you automatically. If an error occur, false
is returned; use ErrorNo() or ErrorMsg() to get the error details.
Since 4.96, we return null if no records were found.
Executes the SQL and returns the first row as an array. The recordset and remaining
rows are discarded for you automatically. If an error occurs, false is returned.
Executes the SQL and returns the all the rows as a 2-dimensional
array. The recordset is discarded for you automatically. If an error occurs,
false is returned. GetArray is a synonym for GetAll.
GetCol($sql,$inputarr=false,$trim=false)
Executes the SQL and returns all elements of the first column as a
1-dimensional array. The recordset is discarded for you automatically. If an error occurs,
false is returned.
CacheGetOne([$secs2cache,]
$sql,$inputarr=false), CacheGetRow([$secs2cache,] $sql,$inputarr=false), CacheGetAll([$secs2cache,]
$sql,$inputarr=false), CacheGetCol([$secs2cache,]
$sql,$inputarr=false,$trim=false)
Similar to above Get* functions, except that the recordset is serialized and
cached in the $ADODB_CACHE_DIR directory for $secs2cache seconds. Good for speeding
up queries on rarely changing data. Note that the $secs2cache parameter is optional.
If omitted, we use the value in $connection->cacheSecs (default is 3600 seconds,
or 1 hour).
Prepares (compiles) an SQL query for repeated execution. Bind parameters
are denoted by ?, except for the oci8 driver, which uses the traditional Oracle :varname
convention.
Returns an array containing the original sql statement
in the first array element; the remaining elements of the array are driver dependent.
If there is an error, or we are emulating Prepare( ), we return the original
$sql string. This is because all error-handling has been centralized in Execute(
).
Prepare( ) cannot be used with functions that use SQL
query rewriting techniques, e.g. PageExecute( ) and SelectLimit( ).
Example:
$stmt = $DB->Prepare('insert into table (col1,col2) values (?,?)');
for ($i=0; $i < $max; $i++)
$DB->Execute($stmt,array((string) rand(), $i));
Also see InParameter(), OutParameter() and PrepareSP() below. Only supported internally by interbase,
oci8 and selected ODBC-based drivers, otherwise it is emulated. There is no
performance advantage to using Prepare() with emulation.
Important: Due to limitations or bugs in PHP, if you are getting errors when
you using prepared queries, try setting $ADODB_COUNTRECS = false before preparing.
This behaviour has been observed with ODBC.
IfNull($field, $nullReplacementValue)
Portable IFNULL function (NVL in Oracle). Returns a string that represents
the function that checks whether a $field is null for the given database, and
if null, change the value returned to $nullReplacementValue. Eg.
$sql = 'SELECT '.$db->IfNull('name', "'- unknown -'"). ' FROM table';
This is not a function, but a property. Some databases have "length" and others "len"
as the function to measure the length of a string. To use this property:
$sql = "SELECT ".$db->length."(field) from table";
$rs = $db->Execute($sql);
This is not a function, but a property. This is a string that holds the sql to
generate a random number between 0.0 and 1.0 inclusive.
This is not a function, but a property. Some databases have "substr" and others "substring"
as the function to retrieve a sub-string. To use this property:
$sql = "SELECT ".$db->substr."(field, $offset, $length) from table";
$rs = $db->Execute($sql);
For all databases, the 1st parameter of substr is the field, the 2nd is the
offset (1-based) to the beginning of the sub-string, and the 3rd is the length of the sub-string.
Generates a bind placeholder portably. For most databases, the bind placeholder
is "?". However some databases use named bind parameters such as Oracle, eg
":somevar". This allows us to portably define an SQL statement with bind parameters:
$sql = 'insert into table (col1,col2) values ('.$DB->Param('a').','.$DB->Param('b').')';
# generates 'insert into table (col1,col2) values (?,?)'
# or 'insert into table (col1,col2) values (:a,:b)'
$stmt = $DB->Prepare($sql);
$stmt = $DB->Execute($stmt,array('one','two'));
PrepareSP($sql,
$cursor=false )
When calling stored procedures in mssql and oci8 (oracle),
and you might want to directly bind to parameters that return values, or
for special LOB handling. PrepareSP() allows you to do so.
Returns the same array or $sql string as Prepare( )
above. If you do not need to bind to return values, you should use Prepare(
) instead.
The 2nd parameter, $cursor is not used except with oci8.
Setting it to true will force OCINewCursor to be called; this is to support
output REF CURSORs.
For examples of usage of PrepareSP( ), see InParameter(
) below.
Note: in the mssql driver, preparing stored procedures
requires a special function call, mssql_init( ), which is called by this
function. PrepareSP( ) is available in all other drivers, and is emulated
by calling Prepare( ).
InParameter($stmt, $var,
$name, $maxLen = 4000, $type = false )
Binds a PHP variable as input to a stored procedure variable.
The parameter $stmt is the value returned by PrepareSP(), $var is
the PHP variable you want to bind, $name is the name of the stored procedure
variable. Optional is $maxLen, the maximum length of the data to bind,
and $type which is database dependant. Consult and docs
at php.net for more info on legal values for $type.
InParameter() is a wrapper function that calls Parameter()
with $isOutput=false. The advantage of this function is that it is self-documenting,
because the $isOutput parameter is no longer needed. Only for mssql and oci8
currently.
Here is an example using oci8:
# For oracle, Prepare and PrepareSP are identical
$stmt = $db->PrepareSP(
"declare RETVAL integer;
begin
:RETVAL := SP_RUNSOMETHING(:myid,:group);
end;");
$db->InParameter($stmt,$id,'myid');
$db->InParameter($stmt,$group,'group',64);
$db->OutParameter($stmt,$ret,'RETVAL');
$db->Execute($stmt);
The same example using mssql:
# @RETVAL = SP_RUNSOMETHING @myid,@group
$stmt = $db->PrepareSP('SP_RUNSOMETHING');
# note that the parameter name does not have @ in front!
$db->InParameter($stmt,$id,'myid');
$db->InParameter($stmt,$group,'group',64);
# return value in mssql - RETVAL is hard-coded name
$db->OutParameter($stmt,$ret,'RETVAL');
$db->Execute($stmt);
Note that the only difference between the oci8 and mssql implementations is $sql.
If $type parameter is set to false, in mssql, $type will be dynamicly determined
based on the type of the PHP variable passed (string
=gt; SQLCHAR, boolean =gt;SQLINT1, integer =gt;SQLINT4 or float/double=gt;SQLFLT8).
In oci8, $type can be set to OCI_B_FILE (Binary-File), OCI_B_CFILE (Character-File),
OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and OCI_B_ROWID (ROWID). To
pass in a null, use $db->Parameter($stmt,
$null=null, 'param').
OutParameter($stmt, $var, $name,
$maxLen = 4000, $type = false )
Binds a PHP variable as output from a stored procedure variable. The parameter $stmt
is the value returned by PrepareSP(), $var is the PHP variable you want to bind, $name
is the name of the stored procedure variable. Optional is $maxLen, the maximum length of the
data to bind, and $type which is database dependant.
OutParameter() is a wrapper function that calls Parameter() with $isOutput=true.
The advantage of this function is that it is self-documenting, because
the $isOutput parameter is no longer needed. Only for mssql
and oci8 currently.
For an example, see InParameter.
Parameter($stmt, $var, $name, $isOutput=false,
$maxLen = 4000, $type = false )
Note: This function is deprecated, because of the new InParameter() and OutParameter() functions.
These are superior because they are self-documenting, unlike Parameter().
Adds a bind parameter suitable for return values or special data handling (eg.
LOBs) after a statement has been prepared using PrepareSP(). Only for mssql
and oci8 currently. The parameters are:
$stmt Statement returned by Prepare() or PrepareSP().
$var PHP variable to bind to. Make sure you pre-initialize it!
$name Name of stored procedure variable name to bind to.
[$isOutput] Indicates direction of parameter 0/false=IN 1=OUT
2= IN/OUT. This is ignored in oci8 as this driver auto-detects the direction.
[$maxLen] Maximum length of the parameter variable.
[$type] Consult and
docs at php.net for
more info on legal values for type.
Lastly, in oci8, bind parameters can be reused without calling PrepareSP( )
or Parameters again. This is not possible with mssql. An oci8 example:
$id = 0; $i = 0;
$stmt = $db->PrepareSP( "update table set val=:i where id=:id");
$db->Parameter($stmt,$id,'id');
$db->Parameter($stmt,$i, 'i');
for ($cnt=0; $cnt < 1000; $cnt++) {
$id = $cnt;
$i = $cnt * $cnt; # works with oci8!
$db->Execute($stmt);
}
Bind($stmt, $var, $size=4001, $type=false, $name=false)
This is a low-level function supported only by the oci8
driver. Avoid using unless you only want to support Oracle. The Parameter(
) function is the recommended way to go with bind variables.
Bind( ) allows you to use bind variables in your sql
statement. This binds a PHP variable to a name defined in an Oracle sql statement
that was previously prepared using Prepare(). Oracle named variables begin with
a colon, and ADOdb requires the named variables be called :0, :1, :2, :3, etc.
The first invocation of Bind() will match :0, the second invocation will match
:1, etc. Binding can provide 100% speedups for insert, select and update statements.
The other variables, $size sets the buffer size for data storage, $type is
the optional descriptor type OCI_B_FILE (Binary-File), OCI_B_CFILE (Character-File),
OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and OCI_B_ROWID (ROWID).
Lastly, instead of using the default :0, :1, etc names, you can define your
own bind-name using $name.
The following example shows 3 bind variables being used:
p1, p2 and p3. These variables are bound to :0, :1 and :2.
$stmt = $DB->Prepare("insert into table (col0, col1, col2) values (:0, :1, :2)");
$DB->Bind($stmt, $p1);
$DB->Bind($stmt, $p2);
$DB->Bind($stmt, $p3);
for ($i = 0; $i < $max; $i++) {
$p1 = ?; $p2 = ?; $p3 = ?;
$DB->Execute($stmt);
}
You can also use named variables:
$stmt = $DB->Prepare("insert into table (col0, col1, col2) values (:name0, :name1, :name2)");
$DB->Bind($stmt, $p1, "name0");
$DB->Bind($stmt, $p2, "name1");
$DB->Bind($stmt, $p3, "name2");
for ($i = 0; $i < $max; $i++) {
$p1 = ?; $p2 = ?; $p3 = ?;
$DB->Execute($stmt);
}
Call this method to install a SQL logging and timing function (using fnExecute).
Then all SQL statements are logged into an adodb_logsql table in a database. If
the adodb_logsql table does not exist, ADOdb will create the table if you have
the appropriate permissions. Returns the previous logging value (true for enabled,
false for disabled). Here are samples of the DDL for selected databases:
mysql:
CREATE TABLE adodb_logsql (
created datetime NOT NULL,
sql0 varchar(250) NOT NULL,
sql1 text NOT NULL,
params text NOT NULL,
tracer text NOT NULL,
timer decimal(16,6) NOT NULL
)
postgres:
CREATE TABLE adodb_logsql (
created timestamp NOT NULL,
sql0 varchar(250) NOT NULL,
sql1 text NOT NULL,
params text NOT NULL,
tracer text NOT NULL,
timer decimal(16,6) NOT NULL
)
mssql:
CREATE TABLE adodb_logsql (
created datetime NOT NULL,
sql0 varchar(250) NOT NULL,
sql1 varchar(4000) NOT NULL,
params varchar(3000) NOT NULL,
tracer varchar(500) NOT NULL,
timer decimal(16,6) NOT NULL
)
oci8:
CREATE TABLE adodb_logsql (

sql0 varchar(250) NOT NULL,
sql1 varchar(4000) NOT NULL,
params varchar(4000),
tracer varchar(4000),
timer decimal(16,6) NOT NULL
)
Usage:
$conn->LogSQL(); // turn on logging
:
$conn->Execute(...);
:
$conn->LogSQL(false); // turn off logging
# output summary of SQL logging results
$perf = NewPerfMonitor($conn);
echo $perf->SuspiciousSQL();
echo $perf->ExpensiveSQL();
One limitation of logging is that rollback also prevents SQL from being logged.
If you prefer to use another name for the table used to store the SQL, you can override it by calling
adodb_perf::table($tablename), where $tablename is the new table name (you will still need to manually
create the table yourself). An example:
include('adodb.inc.php');
include('adodb-perf.inc.php');
adodb_perf::table('my_logsql_table');
Also see Performance Monitor.
fnExecute and fnCacheExecute properties
These two properties allow you to define bottleneck functions for all sql statements
processed by ADOdb. This allows you to perform statistical analysis and query-rewriting
of your sql.
Examples of fnExecute
Here is an example of using fnExecute, to count all cached queries and non-cached
queries, you can do this:
# $db is the connection object
function CountExecs($db, $sql, $inputarray)
{
global $EXECS;
if (!is_array(inputarray)) $EXECS++;
# handle 2-dimensional input arrays
else if (is_array(reset($inputarray))) $EXECS += sizeof($inputarray);
else $EXECS++;
# in PHP4.4 and PHP5, we need to return a value by reference
$null = null;
return $null;
}
# $db is the connection object
function CountCachedExecs($db, $secs2cache, $sql, $inputarray)
{
global $CACHED; $CACHED++;
}
$db = NewADOConnection('mysql');
$db->Connect(...);
$db->fnExecute = 'CountExecs';
$db->fnCacheExecute = 'CountCachedExecs';
:
:
# After many sql statements:`
printf("<p>Total queries=%d; total cached=%d</p>",$EXECS+$CACHED, $CACHED);
The fnExecute function is called before the sql is parsed and executed, so
you can perform a query rewrite. If you are passing in a prepared statement,
then $sql is an array (see Prepare). The fnCacheExecute
function is only called if the recordset returned was cached.
The function parameters match the Execute and CacheExecute functions respectively,
except that $this (the connection object) is passed as the first parameter.
Since ADOdb 3.91, the behaviour of fnExecute varies depending on whether the
defined function returns a value. If it does not return a value, then the $sql
is executed as before. This is useful for query rewriting or counting sql queries.
On the other hand, you might want to replace the Execute function with one
of your own design. If this is the case, then have your function return a value.
If a value is returned, that value is returned immediately, without any further
processing. This is used internally by ADOdb to implement LogSQL() functionality.
ADOConnection Utility Functions
No longer available - removed since 1.99.
Generates the sql string used to concatenate $s1, $s2, etc together. Uses the
string in the concat_operator field to generate the concatenation. Override
this function if a concatenation operator is not used, eg. MySQL.
Returns the concatenated string.
Format the $date in the format the database accepts - the return string is also quoted. This is used
when you are sending dates to the database (eg INSERT, UPDATE or where clause of SELECT statement).
The $date parameter can be a Unix integer timestamp or an ISO format
Y-m-d. Uses the fmtDate field, which holds the format to use. If null or false
or '' is passed in, it will be converted to an SQL null.
Returns the date as a quoted string.
$sql = "select * from atable where created > ".$db->DBDate("$year-$month-$day");
$db->Execute($sql);
Note to retrieve a date column in a specific format, use SQLDate.
Format the $date in the bind format the database accepts. Normally
this means that the date string is not quoted, unlike DBDate, which quotes the string.
$sql = "select * from atable where created > ".$db->Param('0');
// or
$sql = "select * from atable where created > ?";
$db->Execute($sql,array($db->BindDate("$year-$month-$day"));
Format the timestamp $ts in the format the database accepts; this can
be a Unix integer timestamp or an ISO format Y-m-d H:i:s. Uses the fmtTimeStamp
field, which holds the format to use. If null or false or '' is passed in, it
will be converted to an SQL null.
Returns the timestamp as a quoted string.
$sql = "select * from atable where created > ".$db->DBTimeStamp("$year-$month-$day $hr:$min:$secs");
$db->Execute($sql);
Format the timestamp $ts in the bind format the database accepts. Normally
this means that the timestamp string is not quoted, unlike DBTimeStamp, which quotes the string.
$sql = "select * from atable where created > ".$db->Param('0');
// or
$sql = "select * from atable where created > ?";
$db->Execute($sql,array($db->BindTimeStamp("$year-$month-$day $hr:$min:$secs"));
qstr($s,[$magic_quotes_enabled=false])
Quotes a string to be sent to the database. The $magic_quotes_enabled
parameter may look funny, but the idea is if you are quoting a string extracted
from a POST/GET variable, then pass get_magic_quotes_gpc() as the second parameter.
This will ensure that the variable is not quoted twice, once by qstr
and once by the magic_quotes_gpc.
Eg. $s = $db->qstr(HTTP_GET_VARS['name'],get_magic_quotes_gpc());
Returns the quoted string.
Quotes the string $s, escaping the database specific quote character as appropriate.
Formerly checked magic quotes setting, but this was disabled since 3.31 for
compatibility with PEAR DB.
Returns the number of rows affected by a update or delete statement. Returns
false if function not supported.
Not supported by interbase/firebird currently.
Returns the last autonumbering ID inserted. Returns false if function not supported.
Only supported by databases that support auto-increment or object id's, such
as PostgreSQL, MySQL and MS SQL Server currently. PostgreSQL returns the OID, which
can change on a database reload.
Lock a table row for the duration of a transaction. For example to lock record $id in table1:
$DB->StartTrans();
$DB->RowLock("table1","rowid=$id");
$DB->Execute($sql1);
$DB->Execute($sql2);
$DB->CompleteTrans();
Supported in db2, interbase, informix, mssql, oci8, postgres, sybase.
Returns a list of databases available on the server as an array. You have to
connect to the server first. Only available for ODBC, MySQL and ADO.
MetaTables($ttype = false, $showSchema = false,
$mask=false)
Returns an array of tables and views for the current database as an array.
The array should exclude system catalog tables if possible. To only show tables,
use $db->MetaTables('TABLES'). To show only views, use $db->MetaTables('VIEWS').
The $showSchema parameter currently works only for DB2, and when set to true,
will add the schema name to the table, eg. "SCHEMA.TABLE".
You can define a mask for matching. For example, setting $mask = 'TMP%' will
match all tables that begin with 'TMP'. Currently only mssql, oci8, odbc_mssql
and postgres* support $mask.
MetaColumns($table,$notcasesensitive=true)
Returns an array of ADOFieldObject's, one field object for every column of
$table. A field object is a class instance with (name, type, max_length) defined.
Currently Sybase does not recognise date types, and ADO cannot identify
the correct data type (so we default to varchar).
The $notcasesensitive parameter determines whether we uppercase or lowercase the table name to normalize it
(required for some databases). Does not work with MySQL ISAM tables.
For schema support, pass in the $table parameter, "$schema.$tablename". This is only
supported for selected databases.
MetaColumnNames($table,$numericIndex=false)
Returns an array of column names for $table. Since ADOdb 4.22, this is an associative array, with the
keys in uppercase. Set $numericIndex=true if you want the old behaviour of numeric indexes (since 4.23).
e.g. array('FIELD1' =gt; 'Field1', 'FIELD2'=gt;'Field2')
MetaPrimaryKeys($table,
$owner=false)
Returns an array containing column names that are the
primary keys of $table. Supported by mysql, odbc (including db2, odbc_mssql,
etc), mssql, postgres, interbase/firebird, oci8 currently.
Views (and some tables) have primary keys, but sometimes this information is not available from the
database. You can define a function ADODB_View_PrimaryKeys($databaseType, $database, $view, $owner) that
should return an array containing the fields that make up the primary key. If that function exists,
it will be called when MetaPrimaryKeys() cannot find a primary key for a table or view.
// In this example: dbtype = 'oci8', $db = 'mydb', $view = 'dataView', $owner = false
function ADODB_View_PrimaryKeys($dbtype,$db,$view,$owner)
{
switch(strtoupper($view)) {
case 'DATAVIEW': return array('DATAID');
default: return false;
}
}
$db = NewADOConnection('oci8');
$db->Connect('localhost','root','','mydb');
$db->MetaPrimaryKeys('dataView');
Returns an array of containing two elements 'description'
and 'version'. The 'description' element contains the string description of
the database. The 'version' naturally holds the version number (which is also
a string).
MetaForeignKeys($table, $owner=false, $upper=false)
Returns an associate array of foreign keys, or false if not supported. For
example, if table employee has a foreign key where employee.deptkey points to
dept_table.deptid, and employee.posn=posn_table.postionid and employee.poscategory=posn_table.category,
then $conn->MetaForeignKeys('employee') will return
array(
'dept_table' =gt; array('deptkey=deptid'),
'posn_table' =gt; array('posn=positionid','poscategory=category')
)
The optional schema or owner can be defined in $owner. If $upper is true, then
the table names (array keys) are upper-cased.
ADORecordSet
When an SQL statement successfully is executed by ADOConnection->Execute($sql),an
ADORecordSet object is returned. This object contains a virtual cursor so we
can move from row to row, functions to obtain information about the columns
and column types, and helper functions to deal with formating the results to
show to the user.
ADORecordSet Fields
fields: Array containing the current row. This is not associative, but
is an indexed array from 0 to columns-1. See also the function Fields,
which behaves like an associative array.
dataProvider: The underlying mechanism used to connect to the database.
Normally set to native, unless using odbc or ado.
blobSize: Maximum size of a char, string or varchar object before it
is treated as a Blob (Blob's should be shown with textarea's). See the MetaType
function.
sql: Holds the sql statement used to generate this record set.
canSeek: Set to true if Move( ) function works.
EOF: True if we have scrolled the cursor past the last record.
ADORecordSet Functions
ADORecordSet( )
Constructer. Normally you never call this function yourself.
Generates an associative array from the recordset. Note that is this function
is also available in the connection object. More details
can be found there.
Generate a 2-dimensional array of records from the current
cursor position, indexed from 0 to $number_of_rows - 1. If $number_of_rows
is undefined, till EOF.
Generate a 2-dimensional array of records from the current
cursor position. Synonym for GetArray() for compatibility with Microsoft ADO.
GetMenu($name, [$default_str=''],
[$blank1stItem=true], [$multiple_select=false], [$size=0], [$moreAttr=''])
Generate a HTML menu (<select><option><option></select>).
The first column of the recordset (fields[0]) will hold the string to display
in the option tags. If the recordset has more than 1 column, the second column
(fields[1]) is the value to send back to the web server.. The menu will be
given the name $name.
If $default_str is defined, then if $default_str ==
fields[0], that field is selected. If $blank1stItem is true, the first
option is empty. You can also set the first option strings by setting $blank1stItem
= "$value:$text".
$Default_str can be array for a multiple select
listbox.
To get a listbox, set the $size to a non-zero
value (or pass $default_str as an array). If $multiple_select is true
then a listbox will be generated with $size items (or if $size==0,
then 5 items) visible, and we will return an array to a server. Lastly use
$moreAttr to add additional attributes such as javascript or styles.
Menu Example 1: GetMenu('menu1','A',true) will
generate a menu:
for the data (A,1), (B,2), (C,3). Also see example 5.
Menu Example 2: For the same data, GetMenu('menu1',array('A','B'),false) will
generate a menu with both A and B selected:
GetMenu2($name, [$default_str=''],
[$blank1stItem=true], [$multiple_select=false], [$size=0], [$moreAttr=''])
This is nearly identical to GetMenu, except that the
$default_str is matched to fields[1] (the option values).
Menu Example 3: Given the data in menu example 2, GetMenu2('menu1',array('1','2'),false) will
generate a menu with both A and B selected in menu example 2, but this time
the selection is based on the 2nd column, which holds the values to return
to the Web server.
Converts the date string $str to another format.
The date format is Y-m-d, or Unix timestamp format. The default $fmt is
Y-m-d.
Converts the timestamp string $str to another
format. The timestamp format is Y-m-d H:i:s, as in '2002-02-28 23:00:12',
or Unix timestamp format. UserTimeStamp calls UnixTimeStamp to parse $str,
and $fmt defaults to Y-m-d H:i:s if not defined.
Parses the date string $str and returns it in
unix mktime format (eg. a number indicating the seconds after January 1st,
1970). Expects the date to be in Y-m-d H:i:s format, except for Sybase and
Microsoft SQL Server, where M d Y is also accepted (the 3 letter month strings
are controlled by a global array, which might need localisation).
This function is available in both ADORecordSet and
ADOConnection since 1.91.
Parses the timestamp string $str and returns
it in unix mktime format (eg. a number indicating the seconds after January
1st, 1970). Expects the date to be in "Y-m-d, H:i:s" (1970-12-24, 00:00:00)
or "Y-m-d H:i:s" (1970-12-24 00:00:00) or "YmdHis" (19701225000000) format,
except for Sybase and Microsoft SQL Server, where "M d Y h:i:sA" (Dec 25
1970 00:00:00AM) is also accepted (the 3 letter month strings are controlled
by a global array, which might need localisation).
This function is available in both ADORecordSet
and ADOConnection since 1.91.
OffsetDate($dayFraction,
$basedate=false)
Returns a string with the native SQL functions to calculate
future and past dates based on $basedate in a portable fashion. If $basedate
is not defined, then the current date (at 12 midnight) is used. Returns the
SQL string that performs the calculation when passed to Execute().
For example, in Oracle, to find the date and time that
is 2.5 days from today, you can use:
# get date one week from now
$fld = $conn->OffsetDate(7); // returns "(trunc(sysdate)+7")
# get date and time that is 60 hours from current date and time
$fld = $conn->OffsetDate(2.5, $conn->sysTimeStamp); // returns "(sysdate+2.5)"
$conn->Execute("UPDATE TABLE SET dodate=$fld WHERE ID=$id");
This function is available for mysql, mssql, oracle, oci8 and postgresql drivers
since 2.13. It might work with other drivers provided they allow performing
numeric day arithmetic on dates.
SQLDate($dateFormat, $basedate=false)
Returns a string which contains the native SQL functions
to format a date or date column $basedate. This is used when retrieving date columns in SELECT statements.
For sending dates to the database (eg. in UPDATE, INSERT or the where clause of SELECT statements)
use DBDate. It uses a case-sensitive
$dateFormat, which supports:
Y: 4-digit Year
Q: Quarter (1-4)
M: Month (Jan-Dec)
m: Month (01-12)
d: Day (01-31)
H: Hour (00-23)
h: Hour (1-12)
i: Minute (00-59)
s: Second (00-60)
A: AM/PM indicator
w: day of week (0-6 or 1-7 depending on DB)
l: day of week (as string - lowercase L)
W: week in year (0..53 for MySQL, 1..53 for PostgreSQL and Oracle)
All other characters are treated as strings. You can
also use \ to escape characters. Available on selected databases, including
mysql, postgresql, mssql, oci8 and DB2.
This is useful in writing portable sql statements that
GROUP BY on dates. For example to display total cost of goods sold broken
by quarter (dates are stored in a field called postdate):
$sqlfn = $db->SQLDate('Y-\QQ','postdate'); # get sql that formats postdate to output 2002-Q1
$sql = "SELECT $sqlfn,SUM(cogs) FROM table GROUP BY $sqlfn ORDER BY 1 desc";
Move the internal cursor to the next row. The $this->fields array
is automatically updated. Returns false if unable to do so (normally because
EOF has been reached), otherwise true.
If EOF is reached, then the $this->fields array
is set to false (this was only implemented consistently in ADOdb 3.30). For
the pre-3.30 behaviour of $this->fields (at EOF), set the global variable
$ADODB_COMPAT_FETCH = true.
Example:
$rs = $db->Execute($sql);
if ($rs)
while (!$rs->EOF) {
ProcessArray($rs->fields);
$rs->MoveNext();
}
Moves the internal cursor to a specific row $to.
Rows are zero-based eg. 0 is the first row. The fields array is automatically
updated. For databases that do not support scrolling internally, ADOdb will
simulate forward scrolling. Some databases do not support backward scrolling.
If the $to position is after the EOF, $to will move to the
end of the RecordSet for most databases. Some obscure databases using odbc
might not behave this way.
Note: This function uses absolute positioning,
unlike Microsoft's ADO.
Returns true or false. If false, the internal cursor
is not moved in most implementations, so AbsolutePosition( ) will return
the last cursor position before the Move( ).
Internally calls Move(0). Note that some databases do
not support this function.
Internally calls Move(RecordCount()-1). Note that some
databases do not support this function.
Returns an associative array containing the current
row. The keys to the array are the column names. The column names are upper-cased
for easy access. To get the next row, you will still need to call MoveNext().
For example:
Array ( [ID] =gt; 1 [FIRSTNAME] =gt; Caroline [LASTNAME] =gt; Miranda [CREATED]
=gt; 2001-07-05 )
Note: do not use GetRowAssoc() with $ADODB_FETCH_MODE
= ADODB_FETCH_ASSOC. Because they have the same functionality, they will
interfere with each other.
Returns the current page. Requires PageExecute()/CachePageExecute() to be called.
See Example 8.
AtFirstPage($status='')
Returns true if at first page (1-based). Requires PageExecute()/CachePageExecute()
to be called. See Example 8.
AtLastPage($status='')
Returns true if at last page (1-based). Requires PageExecute()/CachePageExecute()
to be called. See Example 8.
Returns the value of the associated column $colname for the current
row. The column name is case-insensitive.
This is a convenience function. For higher performance, use $ADODB_FETCH_MODE.
Returns array containing current row, or false
if EOF. FetchRow( ) internally moves to the next record after returning the
current row.
Warning: Do not mix using FetchRow() with MoveNext().
Usage:
$rs = $db->Execute($sql);
if ($rs)
while ($arr = $rs->FetchRow()) {
# process $arr
}
Sets $array to the current row. Returns PEAR_Error
object if EOF, 1 if ok (DB_OK constant). If PEAR is undefined, false is returned
when EOF. FetchInto( ) internally moves to the next record after returning
the current row.
FetchRow() is easier to use. See above.
Returns an object containing the name, type and max_length of
the associated field. If the max_length cannot be determined reliably, it
will be set to -1. The column numbers are zero-based. See example
2.
Returns the number of fields (columns) in the record
set.
Returns the number of rows in the record set. If the
number of records returned cannot be determined from the database driver
API, we will buffer all rows and return a count of the rows after all the
records have been retrieved. This buffering can be disabled (for performance
reasons) by setting the global variable $ADODB_COUNTRECS = false. When disabled,
RecordCount( ) will return -1 for certain databases. See the supported databases
list above for more details.
RowCount is a synonym for RecordCount.
PO_RecordCount($table,
$where)
Returns the number of rows in the record set. If the
database does not support this, it will perform a SELECT COUNT(*) on the
table $table, with the given $where condition to return an estimate of the
recordset size.
$numrows = $rs->PO_RecordCount("articles_table", "group=$group");
NextRecordSet()
For databases that allow multiple recordsets to be returned
in one query, this function allows you to switch to the next recordset. Currently
only supported by mssql driver.
$rs = $db->Execute('execute return_multiple_rs');
$arr1 = $rs->GetArray();
$rs->NextRecordSet();
$arr2 = $rs->GetArray();
Returns the current row as an object. If you set $toupper
to true, then the object fields are set to upper-case. Note: The newer FetchNextObject()
is the recommended way of accessing rows as objects. See below.
FetchNextObject($toupper=true)
Gets the current row as an object and moves to the next
row automatically. Returns false if at end-of-file. If you set $toupper to
true, then the object fields are set to upper-case. Note that for some drivers such as mssql, you need to SetFetchMode(ADODB_FETCH_ASSOC) or SetFetchMode(ADODB_FETCH_BOTH).
$rs = $db->Execute('select firstname,lastname from table');
if ($rs) {
while ($o = $rs->FetchNextObject()) {
print "$o->FIRSTNAME, $o->LASTNAME<BR>";
}
}
There is some trade-off in speed in using FetchNextObject().
If performance is important, you should access rows with the fields[] array. FetchObj()
Returns the current record as an object. Fields are
not upper-cased, unlike FetchObject.
Returns the current record as an object and moves to
the next record. If EOF, false is returned. Fields are not upper-cased, unlike
FetctNextObject.
Returns the current row of the record set. 0 is the first row.
Synonym for CurrentRow for compatibility with ADO. Returns the current
row of the record set. 0 is the first row.
MetaType($nativeDBType[,$field_max_length],[$fieldobj])
Determine what generic meta type a database field type is given its
native type $nativeDBType as a string and the length of the field $field_max_length.
Note that field_max_length can be -1 if it is not known. The field object returned
by FetchField() can be passed in $fieldobj or as the 1st parameter $nativeDBType.
This is useful for databases such as mysql which has additional properties
in the field object such as primary_key.
Uses the field blobSize and compares it with $field_max_length to
determine whether the character field is actually a blob.
For example, $db->MetaType('char') will return 'C'.
Returns:
- C: Character fields that should be shown in a <input type="text"> tag.
- X: Clob (character large objects), or large text fields that should
be shown in a <textarea>
- D: Date field
- T: Timestamp field
- L: Logical field (boolean or bit-field)
- N: Numeric field. Includes decimal, numeric, floating point, and
real.
- I: Integer field.
- R: Counter or Autoincrement field. Must be numeric.
- B: Blob, or binary large objects.
Since ADOdb 3.0, MetaType accepts $fieldobj
as the first parameter, instead of $nativeDBType.
Closes the recordset, cleaning all memory and resources
associated with the recordset.
If memory management is not an issue, you do not need to
call this function as recordsets are closed for you by PHP at the end of the
script. SQL statements such as INSERT/UPDATE/DELETE do not really return a recordset,
so you do not have to call Close() for such SQL statements.
function rs2html($adorecordset,[$tableheader_attributes],
[$col_titles])
This is a standalone function (rs2html = recordset to
html) that is similar to PHP's odbc_result_all function, it prints
a ADORecordSet, $adorecordset as a HTML table. $tableheader_attributes allow
you to control the table cellpadding, cellspacing and border attributes.
Lastly you can replace the database column names with your own column titles
with the array $col_titles. This is designed more as a quick debugging
mechanism, not a production table recordset viewer.
You will need to include the file tohtml.inc.php.
<?
include('tohtml.inc.php'); # load code common to ADOdb
include('adodb.inc.php'); # load code common to ADOdb
$conn =ADONewConnection('mysql'); # create a connection
$conn->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
$sql = 'select CustomerName, CustomerID from customers';
$rs = $conn->Execute($sql);
rs2html($rs,'border=2 cellpadding=3',array('Customer Name','Customer ID'));
?>
Differences between this ADOdb library and Microsoft
ADO
- ADOdb only supports recordsets created by a connection object. Recordsets
cannot be created independently.
- ADO properties are implemented as functions in ADOdb. This makes it easier
to implement any enhanced ADO functionality in the future.
- ADOdb's ADORecordSet->Move() uses
absolute positioning, not relative. Bookmarks are not supported.
- ADORecordSet->AbsolutePosition() cannot
be used to move the record cursor.
- ADO Parameter objects are not supported. Instead we have the ADOConnection::Parameter(
) function, which provides a simpler interface for calling preparing parameters
and calling stored procedures.
- Recordset properties for paging records are available, but implemented as
in Example 8.
Database Driver Guide
This describes how to create a class to connect to a
new database. To ensure there is no duplication of work, kindly email me
at jlim#natsoft.com.my if you decide to create such a class.
First decide on a name in lower case to call the database
type. Let's say we call it xbase.
Then we need to create two classes ADODB_xbase and ADORecordSet_xbase
in the file adodb-xbase.inc.php.
The simplest form of database driver is an adaptation
of an existing ODBC driver. Then we just need to create the class ADODB_xbase
extends ADODB_odbc to support the new date and timestamp formats,
the concatenation operator used, true and false. For
the ADORecordSet_xbase extends ADORecordSet_odbc we need to change
the MetaType function. See adodb-vfp.inc.php as an example.
More complicated is a totally new database driver that
connects to a new PHP extension. Then you will need to implement several
functions. Fortunately, you do not have to modify most of the complex code.
You only need to override a few stub functions. See adodb-mysql.inc.php for
example.
The default date format of ADOdb internally is YYYY-MM-DD
(Ansi-92). All dates should be converted to that format when passing to an
ADOdb date function. See Oracle for an example how we use ALTER SESSION to
change the default date format in _pconnect _connect.
ADOConnection Functions to Override
Defining a constructor for your ADOConnection derived
function is optional. There is no need to call the base class constructor.
_connect: Low level implementation of Connect.
Returns true or false. Should set the _connectionID.
_pconnect: Low level implemention of PConnect.
Returns true or false. Should set the _connectionID.
_query: Execute a query. Returns the queryID,
or false.
_close: Close the connection -- PHP should clean
up all recordsets.
ErrorMsg: Stores the error message in the private
variable _errorMsg.
ADOConnection Fields to Set
_bindInputArray: Set to true if binding of parameters
for SQL inserts and updates is allowed using ?, eg. as with ODBC.
fmtDate
fmtTimeStamp
true
false
concat_operator
replaceQuote
hasLimit support SELECT * FROM TABLE LIMIT 10
of MySQL.
hasTop support Microsoft style SELECT TOP 10
* FROM TABLE.
ADORecordSet Functions to Override
You will need to define a constructor for your ADORecordSet
derived class that calls the parent class constructor.
FetchField: as documented above in ADORecordSet
_initrs: low level initialization of the recordset:
setup the _numOfRows and _numOfFields fields -- called by the
constructor.
_seek: seek to a particular row. Do not load
the data into the fields array. This is done by _fetch. Returns true or false.
Note that some implementations such as Interbase do not support seek. Set
canSeek to false.
_fetch: fetch a row using the database extension
function and then move to the next row. Sets the fields array. If
the parameter $ignore_fields is true then there is no need to populate the fields array,
just move to the next row. then Returns true or false.
_close: close the recordset
Fields: If the array row returned by the PHP
extension is not an associative one, you will have to override this. See
adodb-odbc.inc.php for an example. For databases such as MySQL and MSSQL
where an associative array is returned, there is no need to override this

Change Log
Active Record: $ADODB_ASSOC_CASE=1 did not work properly. Fixed.
Modified Fields() in recordset class to support display null fields in FetchNextObject().
In ADOdb5, active record implementation, we now support column names with spaces in them - we autoconvert the spaces to _ using
__set(). Thx Daniel Cook. http://phplens.com/lens/lensforum/msgs.php?id=17200
Removed $arg3 from mysqli SelectLimit. See http://phplens.com/lens/lensforum/msgs.php?id=16243. Thx Zsolt Szeberenyi.
Changed oci8 FetchField, which returns the max_length of BLOB/CLOB/NCLOB as 4000 (incorrectly) to -1.
CacheExecute would sometimes return an error on Windows if it was unable to lock the cache file. This is harmless
and has been changed to a warning that can be ignored. Also adodb_write_file() code revised.
ADOdb perf code changed to only log sql if execution time >= 0.05 seconds. New $ADODB_PERF_MIN variable holds min sql timing.
Any SQL with timing value below this and is not causing an error is not logged.
Also adodb_backtrace() now traces 1 level deeper as sometimes actual culprit function is not displayed.
Fixed a group by problem with adodb_getcount() for db's which are not postgres/oci8 based.
Changed mssql driver Parameter() from SQLCHAR to SQLVARCHAR: case 'string': $type = SQLVARCHAR; break.
Problem with mssql driver in php5 (for adodb 5.03) because some functions are not static. Fixed.
4.96/5.02 24 Sept 2007
p>Fix adodb count optimisation. Preg_match did not work properly. Also rewrote the ORDER BY stripping code in _adodb_getcount(), adodb-lib.inc.php.
SelectLimit for oci8 not optimal for large recordsets when offset=0. Changed $nrows check.
Active record optimizations.
Added support for assoc arrays in Set().
Now GetOne returns null if EOF (no records found), and false if error occurs. Use ErrorMsg()/ErrorNo() to get the error.
Added BIT data type support to adodb-ado.inc.php and adodb-ado5.inc.php.
Ldap driver did not return actual ldap error messages. Fixed.
Implemented GetRandRow($sql, $inputarr). Optimized for Oci8.
Changed adodb5 active record to use static SetDatabaseAdapter() and removed php4 constructor. Bas van Beek bas.vanbeek#gmail.com.
Also in adodb5, changed adodb-session2 to use static function declarations in class. Thx Daniel Berlin.
Added "Clear SQL Log" to bottom of Performance screen.
Sessions2 code echo'ed directly to the screen in debug mode. Now uses ADOConnection::outp().
In mysql/mysqli, qstr(null) will return the string "null" instead of empty quoted string "''".
postgresql optimizeTable in perf-postgres.inc.php added by Daniel Berlin (mail#daniel-berlin.de)
Added 5.2.1 compat code for oci8.
Changed @@identity to SCOPE_IDENTITY() for multiple mssql drivers. Thx Stefano Nari.
Code sanitization introduced in 4.95 caused problems in European locales (as float 3.2 was typecast to 3,2). Now we only sanitize if is_numeric fails.
Added support for customizing ADORecordset_empty using $this->rsPrefix.'empty'. By Josh Truwin.
Added proper support for ALterColumnSQL for Postgresql in datadict code. Thx. Josh Truwin.
Added better support for MetaType() in mysqli when using an array recordset.
CacheFlush debug outp() passed in invalid parameters. Fixed.
Added Thai language file for adodb. Thx Trirat Petchsingh rosskouk#gmail.com and Marcos Pont
Added zerofill checking support to MetaColumns for mysql and mysqli.

Added some code sanitization to AutoExecute in adodb-lib.inc.php.
Due to typo, all connections in adodb-oracle.inc.php would become persistent, even non-persistent ones. Fixed.
Oci8 DBTimeStamp uses 24 hour time for input now, so you can perform string comparisons between 2 DBTimeStamp values.
Some PHP4.4 compat issues fixed in adodb-session2.inc.php
For ADOdb 5.01, fixed some adodb-datadict.inc.php MetaType compat issues with PHP5.
The $argHostname was wiped out in adodb-ado5.inc.php. Fixed.
Adodb5 version, added iterator support for adodb_recordset_empty.
Experimental PHP5 version - conforms to E_STRICT (PHP 5.1.6 version),
added static to functions outp(), UnixTimeStamp(), UnixDate(), and removed object references: =& changed to =. Otherwise code is the same as 4.94.
Active Record: $ADODB_ASSOC_CASE=2 did not work properly. Fixed. Thx gmane#auxbuss.com.
mysqli had bugs in BeginTrans() and EndTrans(). Fixed.
Improved error handling when no database is connected for oci8. Thx Andy Hassall.

Added handling of nulls in adodb-ado_mssql.inc.php for qstr(). Thx to Felix Rabinovich.
Adodb-dict contributions by Gaetano:
+ Support for INDEX in data-dict. Example:
idx_ev1. The ability to define indexes using the INDEX keyword was added in ADOdb 4.94. The following example features mutiple indexes, including a compound index idx_ev1.
event_id I(11) NOTNULL AUTOINCREMENT PRIMARY,
event_type I(4) NOTNULL INDEX idx_evt,
event_start_date T DEFAULT NULL INDEX id_esd,
event_end_date T DEFAULT '0000-00-00 00:00:00' INDEX id_eted,
event_parent I(11) UNSIGNED NOTNULL DEFAULT 0 INDEX id_evp,
event_owner I(11) DEFAULT 0 INDEX idx_ev1,
event_project I(11) DEFAULT 0 INDEX idx_ev1,
event_times_recuring I(11) UNSIGNED NOTNULL DEFAULT 0,
event_icon C(20) DEFAULT 'obj/event',
event_description X
+ Prevents the generated SQL from including double drop-sequence statements for REPLACE case of tables with autoincrement columns (on those dbs that emulate it via sequences)
+ makes any date defined as DEFAULT value for D and T columns work cross-database, not just the "sysdate" value (as long as it is specified using adodb standard format). See above example.
Fixed pdo's GetInsertID() support. Thx Ricky Su.
oci8 Prepare() now sets error messages if an error occurs.
Added 'PT_BR' to SetDateLocale() -- brazilian portugese.
charset in oci8 was not set correctly on *Connect()
ADOConnection::Transpose() now appends as first column the field names.
Added $ADODB_QUOTE_FIELDNAMES. If set to true, will autoquote field names in AutoExecute(),GetInsertSQL(), GetUpdateSQL().

Added MetaIndexes() to odbc_mssql.
Added connection property $db->null2null = 'null'. In autoexecute/getinsertsql/getupdatesql, this value will be converted to a null. Set this to a funny invalid value if you do not want null conversion. See http://phplens.com/lens/lensforum/msgs.php?id=15902.
Path disclosure problem in mysqli fixed. Thx Andy.
Fixed typo in session_schema2.xml.

Changed CacheSelectLimit() to flush cache when $secs2cache==-1 due to complaints from other users.
Added support for using memcached with CacheExecute/CacheSelectLimit. Requires memcache module PECL extension. Usage:
$db = NewADOConnection($driver);
$db->memCache = true; /// should we use memCache instead of caching in files
$db->memCacheHost = 126.0.1.1; /// memCache host
$db->memCachePort = 11211; /// this is default memCache port
$db->memCacheCompress = false; /// Use 'true' to store the item compressed (uses zlib)
$db->Connect(...);
$db->CacheExecute($sql);
Implemented Transpose() for recordsets. Recordset must be retrieved using ADODB_FETCH_NUM. First column becomes the
column name.
$DB = NewADOConnection('mysql');
$DB->Connect(...);
$DB->SetFetchMode(ADODB_FETCH_NUM);
$rs = $DB->Execute('select productname,productid,unitprice from products limit 10');
$rs2 = $DB->Transpose($rs);
rs2html($rs2);
Major session code rewrite .... See session docs.
PDO bindinputarray was not set properly for MySQL (changed from true to false).
Changed CacheSelectLimit() to re-cache when $secs2cache==0. This is one way to flush the cache when SelectLimit is called.
Added to quotes to mysql and mysqli: "SHOW COLUMNS FROM `%s`";
Removed accidental optgroup handling in GetMenu().
Fixed ibase _BlobDecode for php5 compat, and also mem alloc issues for small blobs, thx salvatori#interia.pl

Fix for GetAssoc() PHP5 compat. See http://phplens.com/lens/lensforum/msgs.php?id=15425
Active Record - If inserting a record and the value of a primary key field is null, then we do not insert that field in as we assume it is an auto-increment field. Needed by mssql.
Changed postgres7 MetaForeignKeys() see http://phplens.com/lens/lensforum/msgs.php?id=15531
DB2 will now return db2_conn_errormsg() when it is a connection error.
Changed adodb_countrec() in adodb-lib.inc.php to allow LIMIT to be used as a speedup to reduce no of records counted.
Added support for transaction modes for postgres and oci8 with SetTransactionMode().
These transaction modes affect all subsequent transactions of that connection.

GenID() had a bug in the raiseErrorFn handling. Fixed. Thx Marcos Pont.
Datadict name quoting now handles ( ) in index fields correctly - they aren't part of the index field.
Performance monitoring: (1) oci8 Ixora checks moved down; (2) expensive sql changed so that only those sql with
count(*)>1 are shown; (3) changed sql1 field to a length+crc32 checksum - this breaks backward compat.

Added adodbFetchMode to sqlite.
Perf code, added a string typecast to substr in adodb_log_sql().
Postgres: Changed BlobDecode() to use po_loread, added new $maxblobsize parameter, and now it returns the blob instead
of sending it to stdout - make sure to mention that as a compat warning.
Also added $db->IsOID($oid) function; uses a heuristic, not guaranteed to work 100%.
Contributed arabic language file by "El-Shamaa, Khaled" k.el-shamaa#cgiar.org
PHP5 exceptions did not handle @ protocol properly. Fixed.

Improved oci8 SelectLimit() to use Prepare(). By Cristiano Duarte.
Type-cast $row parameter in ifx_fetch_row() to int. Thx stefan bodgan.
Ralf becker contributed improvements in postgresql, sapdb, mysql data dictionary handling:
- MySql and Postgres MetaType was reporting every int column which was
part of a primary key and unique as serial
- Postgres was not reporting the scale of decimal types
- MaxDB was padding the defaults of none-string types with spaces
- MySql now correctly converts enum columns to varchar
Ralf also changed Postgresql datadict:
- you cant add NOT NULL columns in postgres in one go, they need to be
added as NULL and then altered to NOT NULL
- AlterColumnSQL could not change a varchar column with numbers into an
integer column, postgres need an explicit conversation
- a re-created sequence was not set to the correct value, if the name
was the old name (no implicit sequence), now always the new name of the
implicit sequence is used
Sergio Strampelli added extra $intoken check to Lens_ParseArgs() in datadict code.
FetchMode cached in recordset is sometimes mapped to native db fetchMode. Normally this does not matter,
but when using cached recordsets, we need to switch back to using adodb fetchmode. So we cache this
in $rs->adodbFetchMode if it differs from the db's fetchMode.
For informix we now set canSeek = false driver because stefan bodgan tells me that seeking doesn't work.
SetDateLocale() never worked till now ;-) Thx david#tomato.it
Set $_bindInputArray = true in sapdb driver. Required for clob support.
Fixed some PEAR::DB emulation issues with isError() and isWarning. Thx to Gert-Rainer Bitterlich.

Changed odbtp to dynamically change databaseType based on connection, eg. from 'odbtp' to 'odbtp_mssql' when connecting
to mssql database.
In datadict, MySQL I4 was wrongly mapped to MEDIUMINT, which is actually I3. Fixed.
Fixed mysqli MetaType() recognition. Mysqli returns numeric types unlike mysql extension. Thx Francesco Riosa.
VFP odbc driver curmode set wrongly, causing problems with memo fields. Fixed.
Odbc driver did not recognize odbc version 2 driver date types properly. Fixed. Thx Bostjan.
ChangeTableSQL() fixes to datadict-db2.inc.php by Mark Newnham.
Perf monitoring with odbc improved. Now we try in perf code to manually set the sysTimeStamp using date() if sysTimeStamp
is empty.
All ADO errors are thrown as exceptions in PHP5.
So we added exception handling to ado in PHP5 by creating new adodb-ado5.inc.php driver.
Added IsConnected(). Returns true if connection object connected. By Luca.Gioppo.
"Ralf Becker"

Added ADODB_ASSOC_CASE support to postgres/postgres7 driver.
Support for DECLARE stmt in oci8. Thx Lochbrunner.

(but not oci8po), we use the superfast ADOdb extension code for movenext.
Added schema support to mssql and odbc_mssql MetaPrimaryKeys().
Patched MSSQL driver to support PHP NULL and Boolean values
while binding the input array parameters in the _query() function. By Stephen Farmer.

Added normalize support for postgresql (true=lowercase table name, or false=case-sensitive table names)
to MetaColumns($table, $normalize=true).
PHP5 variant dates in ADO not working. Fixed in adodb-ado.inc.php.
Constant ADODB_FORCE_NULLS was not working properly for many releases (for GetUpdateSQL). Fixed.
Also GetUpdateSQL strips off ORDER BY now - thx Elieser Leão.
Perf Monitor for oci8 now dynamically highlights optimizer_* params if too high/low.
Added dsn support to NewADOConnection/ADONewConnection.
Fixed out of page bounds bug in _adodb_pageexecute_all_rows() Thx to "Sergio Strampelli" sergio#rir.it
Speedup of movenext for mysql and oci8 drivers.
Moved debugging code _adodb_debug_execute() to adodb-lib.inc.php.
Fixed postgresql bytea detection bug. See http://phplens.com/lens/lensforum/msgs.php?id=9849.
Fixed ibase datetimestamp typo in PHP5. Thx stefan.
Removed whitespace at end of odbtp drivers.
Added db2 metaprimarykeys fix.
Optimizations to MoveNext() for mysql and oci8. Misc speedups to Get* functions.
Bumped it to 4.50 to avoid confusion with PHP 4.3.x series.
Added db2 metatables and metacolumns extensions.
Added alpha PDO driver. Very buggy, only works with odbc.
Tested mysqli. Set poorAffectedRows = true. Cleaned up movenext() and _fetch().
PageExecute does not work properly with php5 (return val not a variable). Reported Dmytro Sychevsky sych#php.com.ua. Fixed.
MetaTables() for mysql, $showschema parameter was not backward compatible with older versions of adodb. Fixed.
Changed mysql GetOne() to work with mysql 3.23 when using with non-select stmts (e.g. SHOW TABLES).
Changed TRIG_ prefix to a variable in datadict-oci8.inc.php. Thx to Luca.Gioppo#csi.it.
New to adodb-time code. We allow you to define your own daylights savings function,
adodb_daylight_sv for pre-1970 dates. If the function is defined
(somewhere in an include), then you can correct
for daylights savings. See http://phplens.com/phpeverywhere/node/view/16#daylightsavings
for more info.
New sqlitepo driver. This is because assoc mode does not work like other drivers in sqlite.
Namely, when selecting (joining) multiple tables, in assoc mode the table
names are included in the assoc keys in the "sqlite" driver.
In "sqlitepo" driver, the table names are stripped from the returned column names.
When this results in a conflict, the first field get preference.
Contributed by Herman Kuiper herman#ozuzo.net
Added $forcenull parameter to GetInsertSQL/GetUpdateSQL. Idea by Marco Aurelio Silva.
More XHTML changes for GetMenu. By Jeremy Evans.
Fixes some ibase date issues. Thx to stefan bogdan.
Improvements to mysqli driver to support $ADODB_COUNTRECS.
Fixed adodb-csvlib.inc.php problem when reading stream from socket. We need to poll stream continiously.
New interbase/firebird fixes thx to Lester Caine.
Driver fixes a problem with getting field names in the result array, and
corrects a couple of data conversions. Also we default to dialect3 for firebird.
Also ibase sysDate property was wrong. Changed to cast as timestamp.
The datadict driver is set up to give quoted tables and fields as this
was the only way round reserved words being used as field names in
TikiWiki. TikiPro is tidying that up, and I hope to be able to produce a
build of THAT which uses what I consider proper UPPERCASE field and
table names. The conversion of TikiWiki to ADOdb helped in that, but
until the database is completely tidied up in TikiPro ...
Modified _gencachename() to include fetchmode in name hash.
This means you should clear your cache directory after installing this release as the
cache name algorithm has changed.
Now Cache* functions work in safe
mode, because we do not create sub-directories in the $ADODB_CACHE_DIR
in safe mode. In non-safe mode we still create sub-directories. Done by
modifying _gencachename().
Added $gmt parameter (true/false)
to UserDate and UserTimeStamp in connection class, to force conversion
of input (in local time) to be converted to UTC/GMT.
Mssql datadict did not support INT types properly (no size param allowed).
Added _GetSize() to datadict-mssql.inc.php.
For borland_ibase, BeginTrans(), changed:
$this->_transactionID = $this->_connectionID;
to
$this->_transactionID = ibase_trans($this->ibasetrans, $this->_connectionID);
Fixed typo in mysqi_field_seek(). Thx to Sh4dow (sh4dow#php.pl).
LogSQL did not work with Firebird/Interbase. Fixed.
Postgres: made errorno() handling more consistent. Thx to Michael Jahn, Michael.Jahn#mailbox.tu-dresden.de.
Added informix patch to better support metatables, metacolumns by "Cecilio Albero" c-albero#eos-i.com
Cyril Malevanov contributed patch to oci8 to support passing of LOB parameters:
$text = 'test test test';
$sql = "declare rs clob; begin :rs := lobinout(:sa0); end;";
$stmt = $conn -> PrepareSP($sql);
$conn -> InParameter($stmt,$text,'sa0', -1, OCI_B_CLOB);
$rs = '';
$conn -> OutParameter($stmt,$rs,'rs', -1, OCI_B_CLOB);
$conn -> Execute($stmt);
echo "return = ".$rs."<br>";
As he says, the LOBs limitations are:
- use OCINewDescriptor before binding
- if Param is IN, uses save() before each execute. This is done automatically for you.
- if Param is OUT, uses load() after each execute. This is done automatically for you.
- when we bind $var as LOB, we create new descriptor and return it as a
Bind Result, so if we want to use OUT parameters, we have to store
somewhere &$var to load() data from LOB to it.
- IN OUT params are not working now (should not be a big problem to fix it)
- now mass binding not working too (I've wrote about it before)
Simplified Connect() and PConnect() error handling.
When extension not loaded, Connect() and PConnect() will return null. On connect error, the fns will return false.
CacheGetArray() added to code.
Added Init() to adorecordset_empty().
Changed postgres64 driver, MetaColumns() to not strip off quotes in default value if :: detected (type-casting of default).
Added test: if (!defined('ADODB_DIR')) die(). Useful to prevent hackers from detecting file paths.
Changed metaTablesSQL to ignore Postgres 7.4 information schemas (sql_*).
New polish language file by Grzegorz Pacan
Added support for UNION in _adodb_getcount().
Added security check for ADODB_DIR to limit path disclosure issues. Requested by postnuke team.
Added better error message support to oracle driver. Thx to Gaetano Giunta.
Added showSchema support to mysql.
Bind in oci8 did not handle $name=false properly. Fixed.
If extension not loaded, Connect(), PConnect(), NConnect() will return null.
4.22 15 Apr 2004

Fixed session bug when quoting compressed/encrypted data in Replace().
Netezza Driver and LDAP drivers contributed by Josh Eldridge.
GetMenu now uses rtrim() on values instead of trim().
Changed MetaColumnNames to return an associative array, keys being the field names in uppercase.
Suggested fix to adodb-ado.inc.php affected_rows to support PHP5 variants. Thx to Alexios Fakos.
Contributed bulgarian language file by Valentin Sheiretsky valio#valio.eu.org.
Contributed romanian language file by stefan bogdan.
GetInsertSQL now checks for table name (string) in $rs, and will create a recordset for that
table automatically. Contributed by Walt Boring. Also added OCI_B_BLOB in bind on Walt's request - hope
it doesn't break anything :-)
Some minor postgres speedups in _initrs().
ChangeTableSQL checks now if MetaColumns returns empty. Thx Jason Judge.
Added ADOConnection::Time(), returns current database time in unix timestamp format, or false.

Rick Hickerson added CLOB support to db2 datadict.
Added odbtp driver. Thx to "stefan bogdan" sbogdan#rsb.ro.
Changed PrepareSP() 2nd parameter, $cursor, to default to true (formerly false). Fixes oci8 backward
compat problems with OUT params.
Fixed month calculation error in adodb-time.inc.php. 2102-June-01 appeared as 2102-May-32.
Updated PHP5 RC1 iterator support. API changed, hasMore() renamed to valid().
Changed internal format of serialized cache recordsets. As we store a version number, this should be
backward compatible.
Error handling when driver file not found was flawed in ADOLoadCode(). Fixed.
4.20 27 Feb 2004
Updated to AXMLS 1.01.
MetaForeignKeys for postgres7 modified by Edward Jaramilla, works on pg 7.4.
Now numbers accepts function calls or sequences for GetInsertSQL/GetUpdateSQL numeric fields.
Changed quotes of 'delete from $perf_table' to "". Thx Kehui (webmaster#kehui.net)

Tested with php5b4. Fix some php5 compat problems with exceptions and sybase.
Carl-Christian Salvesen added patch to mssql _query to support binds greater than 4000 chars.
Mike suggested patch to PHP5 exception handler. $errno must be numeric.
Added double quotes (") to ADODB_TABLE_REGEX.
For oci8, Prepare(...,$cursor),
$cursor's meaning was accidentally inverted in 4.11. This causes
problems with ExecuteCursor() too, which calls Prepare() internally.
Thx to William Lovaton.
Now dateHasTime property in connection object renamed to datetime for consistency. This could break bc.
Csongor Halmai reports that db2 SelectLimit with input array is not working. Fixed..
4.11 27 Jan 2004
Csongor Halmai reports db2 binding not working. Reverted back to emulated binding.

Table misspelt in perf-oci8.inc.php. Changed v$conn_cache_advice to v$db_cache_advice. Reported by Steve W.
UserTimeStamp and DBTimeStamp did not handle YYYYMMDDHHMMSS format properly. Reported by Mike Muir. Fixed.
Changed oci8 Prepare(). Does not auto-allocate OCINewCursor automatically, unless 2nd param is set to true.
This will break backward compat, if Prepare/Execute is used instead of ExecuteCursor. Reported by Chris Jones.
Added InParameter() and OutParameter(). Wrapper functions to Parameter(), but nicer because they
are self-documenting.
Added 'R' handling in ActualType() to datadict-mysql.inc.php
Added ADOConnection::SerializableRS($rs). Returns a recordset that can be serialized in a session.
Added "Run SQL" to performance UI().
Misc spelling corrections in adodb-mysqli.inc.php, adodb-oci8.inc.php and datadict-oci8.inc.php, from Heinz Hombergs.
MetaIndexes() for ibase contributed by Heinz Hombergs.
4.10 12 Jan 2004
Dan Cech contributed extensive changes to data dictionary to support name quoting (with `), and drop table/index.
Informix added cursorType property. Default remains IFX_SCROLL, but you can change to 0 (non-scrollable cursor) for performance.
Added ADODB_View_PrimaryKeys() for returning view primary keys to MetaPrimaryKeys().
Simplified chinese file, adodb-cn.inc.php from cysoft.
Added check for ctype_alnum in adodb-datadict.inc.php. Thx to Jason Judge.

Rewritten session code by Ross Smith. Moved code to adodb/session directory.
Added function exists check on connecting to most drivers, so we don't crash with the unknown function error.
Smart Transactions failed with GenID() when it no seq table has been created because the sql
statement fails. Fix by Mark Newnham.
Added $db->length, which holds name of function that returns strlen.
Fixed error handling for bad driver in ADONewConnection - passed too few params to error-handler.
Datadict did not handle types like 16.0 properly in _GetSize. Fixed.
Oci8 driver SelectLimit() bug &= instead of = used. Thx to Swen Thümmler.
Jesse Mullan suggested not flushing outp when output buffering enabled. Due to Apache 2.0 bug. Added.
MetaTables/MetaColumns return ref bug with PHP5 fixed in adodb-datadict.inc.php.
New mysqli driver contributed by Arjen de Rijke. Based on adodb 3.40 driver.
Then jlim added BeginTrans, CommitTrans, RollbackTrans, IfNull, SQLDate. Also fixed return ref bug.
$ADODB_FLUSH added, if true then force flush in debugging outp. Default is false. In earlier
versions, outp defaulted to flush, which is not compat with apache 2.0.
Mysql driver's GenID() function did not work when when sql logging is on. Fixed.
$ADODB_SESSION_TBL not declared as global var. Not available if adodb-session.inc.php included in function. Fixed.
The input array not passed to Execute() in _adodb_getcount(). Fixed.
4.04 13 Nov 2003
Switched back to foreach - faster than list-each.
Fixed bug in ado driver - wiping out $this->fields with date fields.
Performance Monitor, View SQL, Explain Plan did not work if strlen($SQL)>max($_GET length). Fixed.

The path to adodb-php4.inc.php and adodb-iterators.inc.php was not setup properly.
Patched SQLDate in interbase to support hours/mins/secs. Thx to ari kuorikoski.
Force autorollback for pgsql persistent connections -
apparently pgsql did not autorollback properly before 4.3.4. See http://bugs.php.net/bug.php?id=25404
4.02 5 Nov 2003
Some errors in adodb_error_pg() fixed. Thx to Styve.
Spurious Insert_ID() error was generated by LogSQL(). Fixed.

More foreach loops optimized with list/each.
Null dates not handled properly in ADO driver (it becomes 31 Dec 1969!).
Heinz Hombergs contributed patches for mysql MetaColumns - adding scale, made
interbase MetaColumns work with firebird/interbase, and added lang/adodb-de.inc.php.
Added INFORMIXSERVER environment variable.

ADOdb Data Dictionary Manual
ӣƵ
ADOdb Data Dictionary Library for PHP
V5.03 22 Jan 2008 (c) 2000-2008 John Lim (jlim#natsoft.com.my).
AXMLS (c) 2004 ars Cognita, Inc
This software is dual licensed using BSD-Style and
LGPL. This means you can use it in compiled proprietary and commercial
products.
Useful ADOdb links:
This documentation describes a PHP class library to automate the
creation of tables, indexes and foreign key constraints portably for
multiple databases. Richard Tango-Lowy and Dan Cech have been kind
enough to contribute AXMLS, an XML schema
system for defining databases. You can contact them at
dcech#phpwerx.net and richtl#arscognita.com.
Currently the following databases are supported:
Well-tested: PostgreSQL, MySQL, Oracle, MSSQL.
Beta-quality: DB2, Informix, Sybase, Interbase, Firebird.
Alpha-quality: MS Access (does not support DEFAULT values) and
generic ODBC.
Example Usage
include_once('adodb.inc.php');
# First create a normal connection
$db = NewADOConnection('mysql');
$db->Connect(...);
# Then create a data dictionary object, using this connection
$dict = NewDataDictionary($db);
# We have a portable declarative data dictionary format in ADOdb, similar to SQL.
# Field types use 1 character codes, and fields are separated by commas.
# The following example creates three fields: "col1", "col2" and "col3":
$flds = "
col1 C(32) NOTNULL DEFAULT 'abc',
col2 I DEFAULT 0,
col3 N(12.2)
";
# We demonstrate creating tables and indexes
$sqlarray = $dict->CreateTableSQL($tabname, $flds, $taboptarray);
$dict->ExecuteSQLArray($sqlarray);
$idxflds = 'co11, col2';
$sqlarray = $dict->CreateIndexSQL($idxname, $tabname, $idxflds);
$dict->ExecuteSQLArray($sqlarray);
More Complex Table Sample
The following string will create a table with a primary key event_id and multiple indexes, including one compound index idx_ev1. The ability to define indexes using the INDEX keyword was added in ADOdb 4.94 by Gaetano Giunta.
$flds = "
event_id I(11) NOTNULL AUTOINCREMENT PRIMARY,
event_type I(4) NOTNULL INDEX idx_evt,
event_start_date T DEFAULT NULL INDEX id_esd,
event_end_date T DEFAULT '0000-00-00 00:00:00' INDEX id_eted,
event_parent I(11) UNSIGNED NOTNULL DEFAULT 0 INDEX id_evp,
event_owner I(11) DEFAULT 0 INDEX idx_ev1,
event_project I(11) DEFAULT 0 INDEX idx_ev1,
event_times_recuring I(11) UNSIGNED NOTNULL DEFAULT 0,
event_icon C(20) DEFAULT 'obj/event',
event_description X
";
$sqlarray = $db->CreateTableSQL($tablename, $flds);
$dict->ExecuteSQLArray($sqlarray);
Class Factory
NewDataDictionary($connection, $drivername=false)
Creates a new data dictionary object. You pass a database connection object in $connection. The $connection does not have to be actually connected to the database. Some database connection objects are generic (eg. odbtp and odbc). Since 4.53, you can tell ADOdb the actual database with $drivername. E.g.
$db = NewADOConnection('odbtp');
$datadict = NewDataDictionary($db, 'mssql'); # force mssql
Class Functions
function CreateDatabase($dbname, $optionsarray=false)
Create a database with the name $dbname;
function CreateTableSQL($tabname, $fldarray, $taboptarray=false)
RETURNS: an array of strings, the sql to be executed, or false
$tabname: name of table
$fldarray: string (or array) containing field info
$taboptarray: array containing table options
The new format of $fldarray uses a free text format, where each
field is comma-delimited.
The first token for each field is the field name, followed by the type
and optional
field size. Then optional keywords in $otheroptions:
"$fieldname $type $colsize $otheroptions"
The older (and still supported) format of $fldarray is a
2-dimensional array, where each row in the 1st dimension represents one
field. Each row has this format:
array($fieldname, $type, [,$colsize] [,$otheroptions]*)
The first 2 fields must be the field name and the field type. The
field type can be a portable type codes or the actual type for that
database.
Legal portable type codes include:
C: Varchar, capped to 255 characters.
X: Larger varchar, capped to 4000 characters (to be compatible with Oracle).
XL: For Oracle, returns CLOB, otherwise the largest varchar size.
C2: Multibyte varchar
X2: Multibyte varchar (largest size)
B: BLOB (binary large object)
D: Date (some databases do not support this, and we return a datetime type)
T: Datetime or Timestamp
L: Integer field suitable for storing booleans (0 or 1)
I: Integer (mapped to I4)
I1: 1-byte integer
I2: 2-byte integer
I4: 4-byte integer
I8: 8-byte integer
F: Floating point number
N: Numeric or decimal number
The $colsize field represents the size of the field. If a decimal
number is used, then it is assumed that the number following the dot is
the precision, so 6.2 means a number of size 6 digits and 2 decimal
places. It is recommended that the default for number types be
represented as a string to avoid any rounding errors.
The $otheroptions include the following keywords (case-insensitive):
AUTO For autoincrement number. Emulated with triggers if not available.
Sets NOTNULL also.
AUTOINCREMENT Same as auto.
KEY Primary key field. Sets NOTNULL also. Compound keys are supported.
PRIMARY Same as KEY.
DEF Synonym for DEFAULT for lazy typists.
DEFAULT The default value. Character strings are auto-quoted unless
the string begins and ends with spaces, eg ' SYSDATE '.
NOTNULL If field is not null.
DEFDATE Set default value to call function to get today's date.
DEFTIMESTAMP Set default to call function to get today's datetime.
NOQUOTE Prevents autoquoting of default string values.
CONSTRAINTS Additional constraints defined at the end of the field
definition.
The Data Dictonary accepts two formats, the older array
specification:
$flds = array(
array('COLNAME', 'DECIMAL', '8.4', 'DEFAULT' =gt; 0, 'NOTNULL'),
array('id', 'I' , 'AUTO'),
array('`MY DATE`', 'D' , 'DEFDATE'),
array('NAME', 'C' , '32', 'CONSTRAINTS' =gt; 'FOREIGN KEY REFERENCES reftable')
);
Or the simpler declarative format:
$flds = "
COLNAME DECIMAL(8.4) DEFAULT 0 NOTNULL,
id I AUTO,
`MY DATE` D DEFDATE,
NAME C(32) CONSTRAINTS 'FOREIGN KEY REFERENCES reftable'
";
Note that if you have special characters in the field name (e.g. My
Date), you should enclose it in back-quotes. Normally field names are
not case-sensitive, but if you enclose it in back-quotes, some
databases will treat the names as case-sensitive (eg. Oracle) , and
others won't. So be careful.
The $taboptarray is the 3rd parameter of the CreateTableSQL
function. This contains table specific settings. Legal keywords include:
- REPLACE
Indicates that the previous table definition should be removed
(dropped)together with ALL data. See first example below.
- DROP
Drop table. Useful for removing unused tables.
- CONSTRAINTS
Define this as the key, with the constraint as the value. See the
postgresql example below. Additional constraints defined for the whole
table. You will probably need to prefix this with a comma.
Database specific table options can be defined also using the name
of the database type as the array key. In the following example, create
the table as ISAM with MySQL, and store the table in the "users"
tablespace if using Oracle. And because we specified REPLACE, drop
the table first.
$taboptarray = array('mysql' =gt; 'TYPE=ISAM', 'oci8' =gt; 'tablespace users', 'REPLACE');
You can also define foreign key constraints. The following is syntax
for postgresql:
$taboptarray = array('constraints' =gt; ', FOREIGN KEY (col1) REFERENCES reftable (refcol)');
function DropTableSQL($tabname)
Returns the SQL to drop the specified table.
function ChangeTableSQL($tabname, $flds)
Checks to see if table exists, if table does not exist, behaves like
CreateTableSQL. If table exists, generates appropriate ALTER TABLE
MODIFY COLUMN commands if field already exists, or ALTER TABLE ADD
$column if field does not exist.
The class must be connected to the database for ChangeTableSQL to
detect the existence of the table. Idea and code contributed by Florian
Buzin.
function RenameTableSQL($tabname,$newname)
Rename a table. Returns the an array of strings, which is the SQL required to rename a table. Since ADOdb 4.53. Contributed by Ralf Becker.
function RenameColumnSQL($tabname,$oldcolumn,$newcolumn,$flds='')
Rename a table field. Returns the an array of strings, which is the SQL required to rename a column. The optional $flds is a complete column-defintion-string like for AddColumnSQL, only used by mysql at the moment. Since ADOdb 4.53. Contributed by Ralf Becker.
function CreateIndexSQL($idxname, $tabname, $flds,
$idxoptarray=false)
RETURNS: an array of strings, the sql to be executed, or false
$idxname: name of index
$tabname: name of table
$flds: list of fields as a comma delimited string or an array of strings
$idxoptarray: array of index creation options
$idxoptarray is similar to $taboptarray in that index specific
information can be embedded in the array. Other options include:
CLUSTERED Create clustered index (only mssql)
BITMAP Create bitmap index (only oci8)
UNIQUE Make unique index
FULLTEXT Make fulltext index (only mysql)
HASH Create hash index (only postgres)
DROP Drop legacy index
function DropIndexSQL ($idxname, $tabname = NULL)
Returns the SQL to drop the specified index.
function AddColumnSQL($tabname, $flds)
Add one or more columns. Not guaranteed to work under all situations.
function AlterColumnSQL($tabname, $flds)
Warning, not all databases support this feature.
function DropColumnSQL($tabname, $flds)
Drop 1 or more columns.
function SetSchema($schema)
Set the schema.
function MetaTables()
function MetaColumns($tab, $upper=true, $schema=false)
function MetaPrimaryKeys($tab,$owner=false,$intkey=false)
function MetaIndexes($table, $primary = false, $owner = false)
These functions are wrappers for the corresponding functions in the
connection object. However, the table names will be autoquoted by the
TableName function (see below) before being passed to the connection
object.
function NameQuote($name = NULL)
If the provided name is quoted with backquotes (`) or contains
special characters, returns the name quoted with the appropriate quote
character, otherwise the name is returned unchanged.
function TableName($name)
The same as NameQuote, but will prepend the current schema if
specified
function MetaType($t,$len=-1,$fieldobj=false)
function ActualType($meta)
Convert between database-independent 'Meta' and database-specific
'Actual' type codes.
function ExecuteSQLArray($sqlarray, $contOnError = true)
RETURNS: 0 if failed, 1 if executed all but with errors, 2 if executed successfully
$sqlarray: an array of strings with sql code (no semicolon at the end of string)
$contOnError: if true, then continue executing even if error occurs
Executes an array of SQL strings returned by CreateTableSQL or
CreateIndexSQL.
ADOdb XML Schema (AXMLS)
This is a class contributed by Richard Tango-Lowy and Dan Cech that
allows the user to quickly
and easily build a database using the excellent ADODB database library
and a simple XML formatted file.
You can .
Quick Start
Adodb-xmlschema, or AXMLS, is a set of classes that allow the user
to quickly and easily build or upgrade a database on almost any RDBMS
using the excellent ADOdb database library and a simple XML formatted
schema file. Our goal is to give developers a tool that's simple to
use, but that will allow them to create a single file that can build,
upgrade, and manipulate databases on most RDBMS platforms.
Installing axmls
The easiest way to install AXMLS to download and install any recent
version of the ADOdb database abstraction library. To install AXMLS
manually, simply copy the adodb-xmlschema.inc.php file and the xsl
directory into your adodb directory.
Using AXMLS in Your Application
There are two steps involved in using AXMLS in your application:
first, you must create a schema, or XML representation of your
database, and second, you must create the PHP code that will parse and
execute the schema.
Let's begin with a schema that describes a typical, if simplistic
user management table for an application.
<?xml version="1.0"?>
<schema version="0.2">
<table name="users">
<desc>A typical users table for our application.</desc>
<field name="userId" type="I">
<descr>A unique ID assigned to each user.</descr>
<KEY/>
<AUTOINCREMENT/>
</field>
<field name="userName" type="C" size="16"><NOTNULL/></field>
<index name="userName">
<descr>Put a unique index on the user name</descr>
<col>userName</col>
<UNIQUE/>
</index>
</table>
<sql>
<descr>Insert some data into the users table.</descr>
<query>insert into users (userName) values ( 'admin' )</query>
<query>insert into users (userName) values ( 'Joe' )</query>
</sql>
</schema>
Let's take a detailed look at this schema.
The opening <?xml version="1.0"?> tag is required by XML. The
<schema> tag tells the parser that the enclosed markup defines an
XML schema. The version="0.2" attribute sets the version of the
AXMLS DTD used by the XML schema.
All versions of AXMLS prior to version 1.0 have a schema version of
"0.1". The current schema version is "0.2".
<?xml version="1.0"?>
<schema version="0.2">
...
</schema>
Next we define one or more tables. A table consists of a fields (and
other objects) enclosed by <table> tags. The name="" attribute
specifies the name of the table that will be created in the database.
<table name="users">
<desc>A typical users table for our application.</desc>
<field name="userId" type="I">
<descr>A unique ID assigned to each user.</descr>
<KEY/>
<AUTOINCREMENT/>
</field>
<field name="userName" type="C" size="16"><NOTNULL/></field>
</table>
This table is called "users" and has a description and two fields.
The description is optional, and is currently only for your own
information; it is not applied to the database.
The first <field> tag will create a field named "userId" of
type "I", or integer. (See the ADOdb Data Dictionary documentation for
a list of valid types.) This <field> tag encloses two special
field options: <KEY/>, which specifies this field as a primary
key, and <AUTOINCREMENT/>, which specifies that the database
engine should automatically fill this field with the next available
value when a new row is inserted.
The second <field> tag will create a field named "userName" of
type "C", or character, and of length 16 characters. The
<NOTNULL/> option specifies that this field does not allow NULLs.
There are two ways to add indexes to a table. The simplest is to
mark a field with the <KEY/> option as described above; a primary
key is a unique index. The second and more powerful method uses the
<index> tags.
<table name="users">
...
<index name="userName">
<descr>Put a unique index on the user name</descr>
<col>userName</col>
<UNIQUE/>
</index>
</table>
The <index> tag specifies that an index should be created on
the enclosing table. The name="" attribute provides the name of the
index that will be created in the database. The description, as above,
is for your information only. The <col> tags list each column
that will be included in the index. Finally, the <UNIQUE/> tag
specifies that this will be created as a unique index.
Finally, AXMLS allows you to include arbitrary SQL that will be
applied to the database when the schema is executed.
<sql>
<descr>Insert some data into the users table.</descr>
<query>insert into users (userName) values ( 'admin' )</query>
<query>insert into users (userName) values ( 'Joe' )</query>
</sql>
The <sql> tag encloses any number of SQL queries that you
define for your own use.
Now that we've defined an XML schema, you need to know how to apply
it to your database. Here's a simple PHP script that shows how to load
the schema.
<?PHP
/* You must tell the script where to find the ADOdb and
* the AXMLS libraries.
*/
require( "path_to_adodb/adodb.inc.php");
require( "path_to_adodb/adodb-xmlschema.inc.php" ); # or adodb-xmlschema03.inc.php
/* Configuration information. Define the schema filename,
* RDBMS platform (see the ADODB documentation for valid
* platform names), and database connection information here.
*/
$schemaFile = 'example.xml';
$platform = 'mysql';
$dbHost = 'localhost';
$dbName = 'database';
$dbUser = 'username';
$dbPassword = 'password';
/* Start by creating a normal ADODB connection.
*/
$db = ADONewConnection( $platform );
$db->Connect( $dbHost, $dbUser, $dbPassword, $dbName );
/* Use the database connection to create a new adoSchema object.
*/
$schema = new adoSchema( $db );
/* Call ParseSchema() to build SQL from the XML schema file.
* Then call ExecuteSchema() to apply the resulting SQL to
* the database.
*/
$sql = $schema->ParseSchema( $schemaFile );
$result = $schema->ExecuteSchema();
?>
Let's look at each part of the example in turn. After you manually
create the database, there are three steps required to load (or
upgrade) your schema.
First, create a normal ADOdb connection. The variables and values
here should be those required to connect to your database.
$db = ADONewConnection( 'mysql' );
$db->Connect( 'host', 'user', 'password', 'database' );
Second, create the adoSchema object that load and manipulate your
schema. You must pass an ADOdb database connection object in order to
create the adoSchema object.
$schema = new adoSchema( $db );
Third, call ParseSchema() to parse the schema and then
ExecuteSchema() to apply it to the database. You must pass
ParseSchema() the path and filename of your schema file.
$schema->ParseSchema( $schemaFile );
$schema->ExecuteSchema();
Execute the above code and then log into your database. If you've
done all this right, you should see your tables, indexes, and SQL.
You can find the source files for this tutorial in the examples
directory as tutorial_shema.xml and tutorial.php. See the class
documentation for a more detailed description of the adoSchema methods,
including methods and schema elements that are not described in this
tutorial.
XML Schema Version 3
In March 2006, we added adodb-xmlschema03.inc.php to the release, which supports version 3 of XML Schema.
The adodb-xmlschema.inc.php remains the same as previous releases, and supports version 2 of XML Schema.
Version 3 provides some enhancements:
- Support for updating table data during an upgrade.
- Support for platform-specific table options and platform negation.
- Support for unsigned fields.
- Fixed opt and constraint support
- Many other fixes such as OPT tag, which allows you to set optional platform settings:
Example usage:
<?xml version="1.0"?>
<schema version="0.3">
<table name="ats_kb">
<descr>ATS KnowledgeBase</descr>
<opt platform="mysql">TYPE=INNODB</opt>
<field name="recid" type="I"/>
<field name="organization_code" type="I4"/>
<field name="sub_code" type="C" size="20"/>
etc...
To use it, change your code to include adodb-xmlschema03.inc.php.
Upgrading
If your schema version is older, than XSLT is used to transform the
schema to the newest version. This means that if you are using an older
XML schema format, you need to have the XSLT extension installed.
If you do not want to require your users to have the XSLT extension
installed, make sure you modify your XML schema to conform to the
latest version.
If you have any questions or comments, please email them to

ADOdb with PHP and Oracle
ӣƵ
Using ADOdb with PHP and Oracle: an advanced tutorial
(c)2004-2005 John Lim. All rights reserved.
1. Introduction
Oracle is the most popular commercial database used with PHP. There are many ways of accessing Oracle databases in PHP. These include:
- The oracle extension
- The oci8 extension
- PEAR DB library
- ADOdb library
The wide range of choices is confusing to someone just starting with Oracle and PHP. I will briefly summarize the differences, and show you the advantages of using .
First we have the C extensions which provide low-level access to Oracle functionality. These C extensions are precompiled into PHP, or linked in dynamically when the web server starts up. Just in case you need it, here's a later in this guide.
ADOdb Example
In ADOdb, the above oci8 example querying the emp table could be written as:
include "/path/to/adodb.inc.php";
$db = NewADOConnection("oci8");
$db->Connect($tnsName, "scott", "tiger");
$rs = $db->Execute("select * from emp where empno>:emp order by empno",
array('emp' => 7900));
while ($arr = $rs->FetchRow()) {
print_r($arr);
echo "<hr>";
}
The Execute( ) function returns a recordset object, and you can retrieve the rows returned using $recordset->FetchRow( ).
If we ignore the initial connection preamble, we can see the ADOdb version is much easier and simpler:
Oci8
ADOdb
$stmt = OCIParse($conn,
"select * from emp where empno > :emp");
$emp = 7900;
OCIBindByName($stmt, ':emp', $emp);
$ok = OCIExecute($stmt);
while (OCIFetchInto($stmt,$arr)) {
print_r($arr);
echo "<hr>";
} $recordset = $db->Execute("select * from emp where empno>:emp",
array('emp' => 7900));
while ($arr = $recordset->FetchRow()) {
print_r($arr);
echo "<hr>";
}
2. ADOdb Query Semantics
You can also query the database using the standard Microsoft ADO MoveNext( ) metaphor. The data array for the current row is stored in the fields property of the recordset object, $rs.
MoveNext( ) offers the highest performance among all the techniques for iterating through a recordset:
$rs = $db->Execute("select * from emp where empno>:emp", array('emp' => 7900));
while (!$rs->EOF) {
print_r($rs->fields);
$rs->MoveNext();
}
And if you are interested in having the data returned in a 2-dimensional array, you can use:
$arr = $db->GetArray("select * from emp where empno>:emp", array('emp' => 7900));
Now to obtain only the first row as an array:
$arr = $db->GetRow("select * from emp where empno=:emp", array('emp' => 7900));
Or to retrieve only the first field of the first row:
$arr = $db->GetOne("select ename from emp where empno=:emp", array('emp' => 7900));
For easy pagination support, we provide the SelectLimit function. The following will perform a select query, limiting it to 100 rows, starting from row 201 (row 1 being the 1st row):
$offset = 200; $limitrows = 100;
$rs = $db->SelectLimit('select * from table', $limitrows, $offset);
The $offset parameter is optional.
Array Fetch Mode
When data is being returned in an array, you can choose the type of array the data is returned in.
- Numeric indexes - use $connection->SetFetchMode(ADODB_FETCH_NUM).
- Associative indexes - the keys of the array are the names of the fields (in upper-case). Use $connection->SetFetchMode(ADODB_FETCH_ASSOC).
- Both numeric and associative indexes - use $connection->SetFetchMode(ADODB_FETCH_BOTH).
The default is ADODB_FETCH_BOTH for Oracle.
Caching
You can define a database cache directory using $ADODB_CACHE_DIR, and cache the results of frequently used queries that rarely change. This is particularly useful for SQL with complex where clauses and group-by's and order-by's. It is also good for relieving heavily-loaded database servers.
This example will cache the following select statement for 3600 seconds (1 hour):
$ADODB_CACHE_DIR = '/var/adodb/tmp';
$rs = $db->CacheExecute(3600, "select names from allcountries order by 1");
There are analogous CacheGetArray(
), CacheGetRow( ), CacheGetOne( ) and CacheSelectLimit( ) functions. The first parameter is the number of seconds to cache. You can also pass a bind array as a 3rd parameter (not shown above).
There is an alternative syntax for the caching functions. The first parameter is omitted, and you set the cacheSecs
property of the connection object:
$ADODB_CACHE_DIR = '/var/adodb/tmp';
$connection->cacheSecs = 3600;
$rs = $connection->CacheExecute($sql, array('id' => 1));
3. Using Prepare( ) For Frequently Used Statements
Prepare( ) is for compiling frequently used SQL statement for reuse. For example, suppose we have a large array which needs to be inserted into an Oracle database. The following will result in a massive speedup in query execution (at least 20-40%), as the SQL statement only needs to be compiled once:
$stmt = $db->Prepare('insert into table (field1, field2) values (:f1, :f2)');
foreach ($arrayToInsert as $key => $value) {
$db->Execute($stmt, array('f1' => $key, 'f2' => $val);
}
4. Working With LOBs
Oracle treats data which is more than 4000 bytes in length specially. These are called Large Objects, or LOBs for short. Binary LOBs are BLOBs, and character LOBs are CLOBs. In most Oracle libraries, you need to do a lot of work to process LOBs, probably because Oracle designed it to work in systems with little memory. ADOdb tries to make things easy by assuming the LOB can fit into main memory.
ADOdb will transparently handle LOBs in select statements. The LOBs are automatically converted to PHP variables without any special coding.
For updating records with LOBs, the functions UpdateBlob( ) and UpdateClob( ) are provided. Here's a BLOB example. The parameters should be self-explanatory:
$ok = $db->Execute("insert into aTable (id, name, ablob)
values (aSequence.nextVal, 'Name', null)");
if (!$ok) return LogError($db->ErrorMsg());
# params: $tableName, $blobFieldName, $blobValue, $whereClause
$db->UpdateBlob('aTable', 'ablob', $blobValue, 'id=aSequence.currVal');
and the analogous CLOB example:
$ok = $db->Execute("insert into aTable (id, name, aclob)
values (aSequence.nextVal, 'Name', null)");
if (!$ok) return LogError($db->ErrorMsg());
$db->UpdateClob('aTable', 'aclob', $clobValue, 'id=aSequence.currVal');
Note that LogError( ) is a user-defined function, and not part of ADOdb.
Inserting LOBs is more complicated. Since ADOdb 4.55, we allow you to do this
(assuming that the photo field is a BLOB, and we want to store $blob_data into
this field, and the primary key is the id field):
$sql = "INSERT INTO photos ( ID, photo) ".
"VALUES ( :id, empty_blob() )".
" RETURNING photo INTO :xx";
$stmt = $db->PrepareSP($sql);
$db->InParameter($stmt, $id, 'id');
$blob = $db->InParameter($stmt, $blob_data, 'xx',-1, OCI_B_BLOB);
$db->StartTrans();
$ok = $db->Execute($stmt);
$db->CompleteTrans();
5. REF CURSORs
Oracle recordsets can be passed around as variables called REF Cursors. For example, in PL/SQL, we could define a function open_tab that returns a REF CURSOR in the first parameter:
TYPE TabType IS REF CURSOR RETURN TAB%ROWTYPE;
PROCEDURE open_tab (tabcursor IN OUT TabType,tablenames IN VARCHAR) IS
BEGIN
OPEN tabcursor FOR SELECT * FROM TAB WHERE tname LIKE tablenames;
END open_tab;
In ADOdb, we could access this REF Cursor using the ExecuteCursor() function. The following will find
all table names that begin with 'A' in the current schema:
$rs = $db->ExecuteCursor("BEGIN open_tab(:refc,'A%'); END;",'refc');
while ($arr = $rs->FetchRow()) print_r($arr);
The first parameter is the PL/SQL statement, and the second parameter is the name of the REF Cursor.
6. In and Out Parameters
The following PL/SQL
stored procedure requires an input variable, and returns a result into an output variable:
PROCEDURE data_out(input IN VARCHAR, output OUT VARCHAR) IS
BEGIN
output := 'I love '||input;
END;
The following ADOdb code allows you to call the stored procedure:
$stmt = $db->PrepareSP("BEGIN adodb.data_out(:a1, :a2); END;");
$input = 'Sophia Loren';
$db->InParameter($stmt,$input,'a1');
$db->OutParameter($stmt,$output,'a2');
$ok = $db->Execute($stmt);
if ($ok) echo ($output == 'I love Sophia Loren') ? 'OK' : 'Failed';
PrepareSP( ) is a special function that knows about bind parameters.
The main limitation currently is that IN OUT parameters do not work.
Bind Parameters and REF CURSORs
We could also rewrite the REF CURSOR example to use InParameter (requires ADOdb 4.53 or later):
$stmt = $db->PrepareSP("BEGIN adodb.open_tab(:refc,:tabname); END;");
$input = 'A%';
$db->InParameter($stmt,$input,'tabname');
$rs = $db->ExecuteCursor($stmt,'refc');
while ($arr = $rs->FetchRow()) print_r($arr);
Bind Parameters and LOBs
You can also operate on LOBs. In this example, we have IN and OUT parameters using CLOBs.
$text = 'test test test';
$sql = "declare rs clob; begin :rs := lobinout(:sa0); end;";
$stmt = $conn -> PrepareSP($sql);
$conn -> InParameter($stmt,$text,'sa0', -1, OCI_B_CLOB); # -1 means variable length
$rs = '';
$conn -> OutParameter($stmt,$rs,'rs', -1, OCI_B_CLOB);
$conn -> Execute($stmt);
echo "return = ".$rs."<br>";
Similarly, you can use the constant OCI_B_BLOB to indicate that you are using BLOBs.
Reusing Bind Parameters with CURSOR_SHARING=FORCE
Many web programmers do not care to use bind parameters, and prefer to enter the SQL directly. So instead of:
$arr = $db->GetArray("select * from emp where empno>:emp", array('emp' => 7900));
They prefer entering the values inside the SQL:
$arr = $db->GetArray("select * from emp where empno>7900");
This reduces Oracle performance because Oracle will reuse compiled SQL which is identical to previously compiled SQL. The above example with the values inside the SQL
is unlikely to be reused. As an optimization, from Oracle 8.1 onwards, you can set the following session parameter after you login:
ALTER SESSION SET CURSOR_SHARING=FORCE
This will force Oracle to convert all such variables (eg. the 7900 value) into constant bind parameters, improving SQL reuse.
More .
7. Dates and Datetime in ADOdb
There are two things you need to know about dates in ADOdb.
First, to ensure cross-database compability, ADOdb assumes that dates are returned in ISO format (YYYY-MM-DD H24:MI:SS).
Secondly, since Oracle treats dates and datetime as the same data type, we decided not to display the time in the default date format. So on login, ADOdb will set the NLS_DATE_FORMAT to 'YYYY-MM-DD'. If you prefer to show the date and time by default, do this:
$db = NewADOConnection('oci8');
$db->NLS_DATE_FORMAT = 'RRRR-MM-DD HH24:MI:SS';
$db->Connect($tns, $user, $pwd);
Or execute:
$sql = quot;ALTER SESSION SET NLS_DATE_FORMAT = 'RRRR-MM-DD HH24:MI:SS'";
$db->Execute($sql);
If you are not concerned about date portability and do not use ADOdb's portability layer, you can use your preferred date format instead.
8. Database Portability Layer
ADOdb provides the following functions for portably generating SQL functions
as strings to be merged into your SQL statements:
Function
Description
DBDate($date)
Pass in a UNIX timestamp or ISO date and it will convert it to a date
string formatted for INSERT/UPDATE
DBTimeStamp($date)
Pass in a UNIX timestamp or ISO date and it will convert it to a timestamp
string formatted for INSERT/UPDATE
SQLDate($date, $fmt)
Portably generate a date formatted using $fmt mask, for use in SELECT
statements.
OffsetDate($date, $ndays)
Portably generate a $date offset by $ndays.
Concat($s1, $s2, ...)
Portably concatenate strings. Alternatively, for mssql use mssqlpo driver,
which allows || operator.
IfNull($fld, $replaceNull)
Returns a string that is the equivalent of MySQL IFNULL or Oracle NVL.
Param($name)
Generates bind placeholders, using ? or named conventions as appropriate.
$db->sysDate Property that holds the SQL function that returns today's date
$db->sysTimeStamp Property that holds the SQL function that returns the current
timestamp (date+time).
$db->concat_operator Property that holds the concatenation operator
$db->length Property that holds the name of the SQL strlen function.
$db->upperCase Property that holds the name of the SQL strtoupper function.
$db->random Property that holds the SQL to generate a random number between 0.00 and 1.00.
$db->substr Property that holds the name of the SQL substring function.
ADOdb also provides multiple oracle oci8 drivers for different scenarios:
Driver Name
Description
oci805
Specifically for Oracle 8.0.5. This driver has a slower SelectLimit( ).
oci8
The default high performance driver. The keys of associative arrays returned in a recordset are upper-case.
oci8po
The portable Oracle driver. Slightly slower than oci8. This driver uses ? instead of :bindvar for binding variables, which is the standard for other databases. Also the keys of associative arrays are in lower-case like other databases.
Here's an example of calling the oci8po driver. Note that the bind variables use question-mark:
$db = NewADOConnection('oci8po');
$db->Connect($tns, $user, $pwd);
$db->Execute("insert into atable (f1, f2) values (?,?)", array(12, 'abc'));
9. Connecting to Oracle
Before you can use ADOdb, you need to have the Oracle client installed and setup the oci8 extension. This extension comes pre-compiled for Windows (but you still need to enable it in the php.ini file). For information on compiling the oci8 extension for PHP and Apache on Unix, there is an excellent guide at .
Should You Use Persistent Connections
One question that is frequently asked is should you use persistent connections to Oracle. Persistent connections allow PHP to recycle existing connections, reusing them after the previous web pages have completed. Non-persistent connections close automatically after the web page has completed. Persistent connections are faster because the cost of reconnecting is expensive, but there is additional resource overhead. As an alternative, Oracle allows you to pool and reuse server processes; this is called (also known as MTS).
The author's benchmarks suggest that using non-persistent connections and the Shared Server configuration offer the best performance. If Shared Server is not an option, only then consider using persistent connections.
Connection Examples
Just in case you are having problems connecting to Oracle, here are some examples:
a. PHP and Oracle reside on the same machine, use default SID, with non-persistent connections:
$conn = NewADOConnection('oci8');
$conn->Connect(false, 'scott', 'tiger');
b. TNS Name defined in tnsnames.ora (or ONAMES or HOSTNAMES), eg. 'myTNS', using persistent connections:
$conn = NewADOConnection('oci8');
$conn->PConnect(false, 'scott', 'tiger', 'myTNS');
or
$conn->PConnect('myTNS', 'scott', 'tiger');
c. Host Address and SID
$conn->connectSID = true;
$conn->Connect('192.168.0.1', 'scott', 'tiger', 'SID');
d. Host Address and Service Name
$conn->Connect('192.168.0.1', 'scott', 'tiger', 'servicename');
e. Oracle connection string:
$cstr = "(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=$host)(PORT=$port))
(CONNECT_DATA=(SID=$sid)))";
$conn->Connect($cstr, 'scott', 'tiger');
f. ADOdb data source names (dsn):
$dsn = 'oci8://user:pwd@tnsname/?persist'; # persist is optional
$conn = ADONewConnection($dsn); # no need for Connect/PConnect
$dsn = 'oci8://user:pwd@host/sid';
$conn = ADONewConnection($dsn);
$dsn = 'oci8://user:pwd@/'; # oracle on local machine
$conn = ADONewConnection($dsn);
With ADOdb data source names,
you don't have to call Connect( ) or PConnect( ).
10. Error Checking
The examples in this article are easy to read but a bit simplistic because we ignore error-handling. Execute( ) and Connect( ) will return false on error. So a more realistic way to call Connect( ) and Execute( ) is:
function InvokeErrorHandler()
{
global $db; ## assume global
MyLogFunction($db->ErrorNo(), $db->ErrorMsg());
}
if (!$db->Connect($tns, $usr, $pwd)) InvokeErrorHandler();
$rs = $db->Execute("select * from emp where empno>:emp order by empno",
array('emp' => 7900));
if (!$rs) return InvokeErrorHandler();
while ($arr = $rs->FetchRow()) {
print_r($arr);
echo "<hr>";
}
You can retrieve the error message and error number of the last SQL statement executed from ErrorMsg( ) and ErrorNo( ). You can also by this author.
- Oracle has an excellent
- PHP manual pages
- . All SQL logged can be
analyzed through the performance monitor UI. In the View
SQL mode, we categorize the SQL into 3 types:
- Suspicious SQL: queries with high average execution times,
and are potential candidates for rewriting
- Expensive SQL: queries with high total execution times
(#executions * avg execution time). Optimizing these queries will
reduce your database server load.
- Invalid SQL: queries that generate errors.
Each query is hyperlinked to a description of the query plan, and
every PHP script that executed that query is also shown.
Please note that the information presented is a very basic database
health check, and does not provide a complete overview of database
performance. Although some attempt has been made to make it work across
multiple databases in the same way, it is impossible to do so. For the
health check, we do try to display the following key database
parameters for all drivers:
- data cache size - The amount of memory allocated to the
cache.
- data cache hit ratio - A measure of how effective the
cache is, as a percentage. The higher, the better.
- current connections - The number of sessions currently
connected to the database.
You will need to connect to the database as an administrator to view
most of the parameters.
Code improvements as very welcome, particularly adding new database
parameters and automated tuning hints.
Usage
Currently, the following drivers: mysql, postgres,
oci8, mssql, informix and db2 are
supported. To create a new performance monitor, call NewPerfMonitor( )
as demonstrated below:
<?php
include_once('adodb.inc.php');
session_start(); # session variables required for monitoring
$conn = ADONewConnection($driver);
$conn->Connect($server,$user,$pwd,$db);
$perf =amp; NewPerfMonitor($conn);
$perf->UI($pollsecs=5);
?>
It is also possible to retrieve a single database parameter:
$size = $perf->DBParameter('data cache size');
Thx to Fernando Ortiz for the informix module.
Methods
function UI($pollsecs=5)
Creates a web-based user interface for performance monitoring. When
you click on Poll, server statistics will be displayed every $pollsecs
seconds. See Usage above.
Since 4.11, we allow users to enter and run SQL interactively via
the "Run SQL" link. To disable this for security reasons, set this
constant before calling $perf->UI().
define('ADODB_PERF_NO_RUN_SQL',1);
Sample output follows below:

WS-CPU% is the Web Server CPU load of the server that PHP is
running from (eg. the database client), and not the database. The Hit%
is the data cache hit ratio. Sess is the current number of
sessions connected to the database. If you are using persistent
connections, this should not change much. The Reads/s and Writes/s
are synthetic values to give the viewer a rough guide to I/O, and are
not to be taken literally.
function SuspiciousSQL($numsql=10)
Returns SQL which have high average execution times as a HTML table.
Each sql statement
is hyperlinked to a new window which details the execution plan and the
scripts that execute this SQL.
The number of statements returned is determined by $numsql. Data is
taken from the adodb_logsql table, where the sql statements are logged
when
$connection->LogSQL(true) is enabled. The adodb_logsql table is
populated using $conn->LogSQL.
For Oracle, Ixora Suspicious SQL returns a list of SQL statements
that are most cache intensive as a HTML table. These are data intensive
SQL statements that could benefit most from tuning.
function ExpensiveSQL($numsql=10)
Returns SQL whose total execution time (avg time * #executions) is
high as a HTML table. Each sql statement
is hyperlinked to a new window which details the execution plan and the
scripts that execute this SQL.
The number of statements returned is determined by $numsql. Data is
taken from the adodb_logsql table, where the sql statements are logged
when
$connection->LogSQL(true) is enabled. The adodb_logsql table is
populated using $conn->LogSQL.
For Oracle, Ixora Expensive SQL returns a list of SQL statements
that are taking the most CPU load when run.
function InvalidSQL($numsql=10)
Returns a list of invalid SQL as an HTML table.
Data is taken from the adodb_logsql table, where the sql statements
are logged when
$connection->LogSQL(true) is enabled.
function Tables($orderby=1)
Returns information on all tables in a database, with the first two
fields containing the table name and table size, the remaining fields
depend on the database driver. If $orderby is set to 1, it will sort by
name. If $orderby is set to 2, then it will sort by table size. Some
database drivers (mssql and mysql) will ignore the $orderby clause. For
postgresql, the information is up-to-date since the last vacuum.
Not supported currently for db2.
Raw Functions
Raw functions return values without any formatting.
function DBParameter($paramname)
Returns the value of a database parameter, such as
$this->DBParameter("data cache size").
function CPULoad()
Returns the CPU load of the database client (NOT THE SERVER) as a
percentage. Only works for Linux and Windows. For Windows, WMI must be
available.
$ADODB_PERF_MIN
New in adodb 4.97/5.03 is this global variable, which controls whether sql timings which are too small are not saved. Currently it defaults
to 0.05 (seconds). This means that all sql's which are faster than 0.05 seconds to execute are not saved.
Format of $settings Property
To create new database parameters, you need to understand
$settings. The $settings data structure is an associative array. Each
element of the array defines a database parameter. The key is the name
of the database parameter. If no key is defined, then it is assumed to
be a section break, and the value is the name of the section break. If
this is too confusing, looking at the source code will help a lot!
Each database parameter is itself an array consisting of the
following elements:
- Category code, used to group related db parameters. If the
category code is 'HIDE', then
the database parameter is not shown when HTML() is called.
- either
- sql string to retrieve value, eg. "select value from
v\$parameter where name='db_block_size'",
- array holding sql string and field to look for, e.g.
array('show variables','table_cache'); optional 3rd parameter is the
$rs->fields[$index] to use (otherwise $index=1), and optional 4th
parameter is a constant to multiply the result with (typically 100 for
percentage calculations),
- a string prefixed by =, then a PHP method of the class is
invoked, e.g. to invoke $this->GetIndexValue(), set this array
element to '=GetIndexValue',
- Description of database parameter. If description begins with an
=, then it is interpreted as a method call, just as in (1c) above,
taking one parameter, the current value. E.g. '=GetIndexDescription'
will invoke $this->GetIndexDescription($val). This is useful for
generating tuning suggestions. For an example, see WarnCacheRatio().
Example from MySQL, table_cache database parameter:
'table cache' =gt; array('CACHE', # category code
array("show variables", 'table_cache'), # array (type 1b)
'Number of tables to keep open'), # description

Introduction
This document discusses the newer session handler adodb-session2.php. If
you have used the older adodb-session.php, then be forewarned that you will
need to alter your session table format. Otherwise everything is backward
compatible.
Here are the older
docs for
adodb-session.php.
Why Session Variables in a Database?
We store state information specific to a user or web
client in session variables. These session variables persist throughout a
session, as the user moves from page to page.
To use session variables, call session_start() at the beginning of
your web page, before your HTTP headers are sent. Then for every
variable you want to keep alive for the duration of the session, call
session_register($variable_name). By default, the session handler will
keep track of the session by using a cookie. You can save objects or
arrays in session variables also.
The default method of storing sessions is to store it in a file.
However if you have special needs such as you:
- Have multiple web servers that need to share session info
- Need to do special processing of each session
- Require notification when a session expires
The ADOdb session handler provides you with the above
additional capabilities by storing the session information as records
in a database table that can be shared across multiple servers.
These records will be garbage collected based on the php.ini [session] timeout settings.
You can register a notification function to notify you when the record has expired and
is about to be freed by the garbage collector.
An alternative to using a database backed session handler is to use .
This is a distributed memory based caching system suitable for storing session
information.
The Improved Session Handler
In ADOdb 4.91, we added a new session handler, in adodb-session2.php.
It features the following improvements:
- Fully supports server farms using a new database table format. The
previous version used the web server time for timestamps, which can cause problems
on a system with multiple web servers with possibly inconsistent
times. The new version uses the database server time instead for all timestamps.
- The older database table format is obsolete. The database table must be modified
to support storage of the database server time mentioned above. Also the field
named DATA has been changed to SESSDATA. In some databases, DATA is a reserved
word.
- The functions dataFieldName() and syncSeconds() is obsolete.
Usage is
include_once("adodb/session/adodb-session2.php");
ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
session_start();
#
# Test session vars, the following should increment on refresh
#
$_SESSION['AVAR'] += 1;
print "<p>\$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";
When the session is created in session_start( ), the global variable $ADODB_SESS_CONN holds
the connection object.
The default name of the table is sessions2. If you want to override it:
include_once("adodb/session/adodb-session2.php");
$options['table'] = 'mytablename';
ADOdb_Session::config($driver, $host, $user, $password, $database,$options);
session_start();
ADOdb Session Handler Features
- Ability to define a notification function that is called when a
session expires. Typically
used to detect session logout and release global resources.
- Optimization of database writes. We crc32 the session data and
only perform an update
to the session data if there is a data change.
- Support for large amounts of session data with CLOBs (see
adodb-session-clob2.php). Useful
for Oracle.
- Support for encrypted session data, see
adodb-cryptsession2.php. Enabling encryption is simply a matter of
including adodb-cryptsession2.php instead of adodb-session2.php.
Session Handler Files
There are 3 session management files that you can use:
adodb-session2.php : The default
adodb-cryptsession2.php : Use this if you want to store encrypted session data in the database
adodb-session-clob2.php : Use this if you are storing DATA in clobs and you are NOT using oci8 driver
Usage Examples
To force non-persistent connections, call Persist() first before session_start():
include_once("adodb/session/adodb-session2.php");
$driver = 'mysql'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
ADOdb_session::Persist($connectMode=false);
session_start();
The parameter to the Persist( ) method sets the connection mode. You can
pass the following:
$connectMode
Connection Method
true
PConnect( )
false
Connect( )
'N'
NConnect( )
'P'
PConnect( )
'C'
Connect( )
To use a encrypted sessions, simply replace the file adodb-session2.php:
include('adodb/session/adodb-cryptsession2.php');
$driver = 'mysql'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
adodb_sess_open(false,false,$connectMode=false);
session_start();
And the same technique for adodb-session-clob2.php:
include('adodb/session/adodb-session2-clob2.php');
$driver = 'oci8'; $host = 'localhost'; $user = 'auser'; $pwd = 'secret'; $database = 'sessiondb';
ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false);
adodb_sess_open(false,false,$connectMode=false);
session_start();
Installation
1. Create this table in your database. Here is the MySQL version:
CREATE TABLE sessions2(
sesskey VARCHAR( 64 ) NOT NULL DEFAULT '',
expiry DATETIME NOT NULL ,
expireref VARCHAR( 250 ) DEFAULT '',
created DATETIME NOT NULL ,
modified DATETIME NOT NULL ,
sessdata LONGTEXT DEFAULT '',
PRIMARY KEY ( sesskey ) ,
INDEX sess2_expiry( expiry ),
INDEX sess2_expireref( expireref )
)
For PostgreSQL, use:
CREATE TABLE sessions2(
sesskey VARCHAR( 64 ) NOT NULL DEFAULT '',
expiry TIMESTAMP NOT NULL ,
expireref VARCHAR( 250 ) DEFAULT '',
created TIMESTAMP NOT NULL ,
modified TIMESTAMP NOT NULL ,
sessdata TEXT DEFAULT '',
PRIMARY KEY ( sesskey )
);
create INDEX sess2_expiry on sessions2( expiry );
create INDEX sess2_expireref on sessions2 ( expireref );
Here is the Oracle definition, which uses a CLOB for the SESSDATA field:
CREATE TABLE SESSIONS2
(
SESSKEY VARCHAR2(48 BYTE) NOT NULL,
EXPIRY DATE NOT NULL,
EXPIREREF VARCHAR2(200 BYTE),
CREATED DATE NOT NULL,
MODIFIED DATE NOT NULL,
SESSDATA CLOB,
PRIMARY KEY(SESSKEY)
);
CREATE INDEX SESS2_EXPIRY ON SESSIONS2(EXPIRY);
CREATE INDEX SESS2_EXPIREREF ON SESSIONS2(EXPIREREF);
We need to use a CLOB here because for text greater than 4000 bytes long,
Oracle requires you to use the CLOB data type. If you are using the oci8 driver,
ADOdb will automatically enable CLOB handling. So you can use either adodb-session2.php
or adodb-session-clob2.php - in this case it doesn't matter.
Notifications
You can receive notification when your session is cleaned up by the session garbage collector or
when you call session_destroy().
PHP's session extension will automatically run a special garbage collection function based on
your php.ini session.cookie_lifetime and session.gc_probability settings. This will in turn call
adodb's garbage collection function, which can be setup to do notification.
PHP Session --> ADOdb Session --> Find all recs --> Send --> Delete queued
GC Function GC Function to be deleted notification records
executed at called by for all recs
random time Session Extension queued for deletion
When a session is created, we need to store a value in the session record (in the EXPIREREF field), typically
the userid of the session. Later when the session has expired, just before the record is deleted,
we reload the EXPIREREF field and call the notification function with the value of EXPIREREF, which
is the userid of the person being logged off.
ADOdb uses a global variable $ADODB_SESSION_EXPIRE_NOTIFY that you must predefine before session
start to store the notification configuration.
$ADODB_SESSION_EXPIRE_NOTIFY is an array with 2 elements, the
first being the name of the session variable you would like to store in
the EXPIREREF field, and the 2nd is the notification function's name.
For example, suppose we want to be notified when a user's session has expired,
based on the userid. When the user logs in, we store the id in the global session variable
$USERID. The function name is 'NotifyFn'.
So we define (before session_start() is called):
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
And when the NotifyFn is called (when the session expires), the
$USERID is passed in as the first parameter, eg. NotifyFn($userid, $sesskey). The
session key (which is the primary key of the record in the sessions
table) is the 2nd parameter.
Here is an example of a Notification function that deletes some
records in the database and temporary files:
function NotifyFn($expireref, $sesskey)
{
global $ADODB_SESS_CONN; # the session connection object
$user = $ADODB_SESS_CONN->qstr($expireref);
$ADODB_SESS_CONN->Execute("delete from shopping_cart where user=$user");
system("rm /work/tmpfiles/$expireref/*");
}
NOTE 1: If you have register_globals disabled in php.ini, then you
will have to manually set the EXPIREREF. E.g.
$GLOBALS['USERID'] = GetUserID();
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
NOTE 2: If you want to change the EXPIREREF after the session
record has been created, you will need to modify any session variable
to force a database record update.
Neat Notification Tricks
ExpireRef normally holds the user id of the current session.
1. You can then write a session monitor, scanning expireref to see
who is currently logged on.
2. If you delete the sessions record for a specific user, eg.
delete from sessions where expireref = '$USER'
then the user is logged out. Useful for ejecting someone from a
site.
3. You can scan the sessions table to ensure no user
can be logged in twice. Useful for security reasons.
Compression/Encryption Schemes
Since ADOdb 4.05, thanks to Ross Smith, multiple encryption and
compression schemes are supported. Currently, supported are:
MD5Crypt (crypt.inc.php)
MCrypt
Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)
GZip
BZip2
These are stackable. E.g.
ADODB_Session::filter(new ADODB_Compress_Bzip2());
ADODB_Session::filter(new ADODB_Encrypt_MD5());
will compress and then encrypt the record in the database.
Session Cookie Regeneration: adodb_session_regenerate_id()
Dynamically change the current session id with a newly generated one and update
database. Currently only works with cookies. Useful to improve security by
reducing the risk of session-hijacking. See this article on Backwards Compatability
The older method of connecting to ADOdb using global variables is still supported:
$ADODB_SESSION_DRIVER='mysql';
$ADODB_SESSION_CONNECT='localhost';
$ADODB_SESSION_USER ='root';
$ADODB_SESSION_PWD ='abc';
$ADODB_SESSION_DB ='phplens';
include('path/to/adodb/session/adodb-session2.php');
In the above example, the only things you need to change in your code to upgrade
is
- your session table format to the new one.
- the include file from adodb-session.php to adodb-session2.php.

have been moved to its own folder, adodb/session. This is a rewrite
of the session code by Ross Smith. The old session code is in
adodb/session/old.
ADOdb Session Handler Features
- Ability to define a notification function that is called when a
session expires. Typically
used to detect session logout and release global resources.
- Optimization of database writes. We crc32 the session data and
only perform an update
to the session data if there is a data change.
- Support for large amounts of session data with CLOBs (see
adodb-session-clob.php). Useful
for Oracle.
- Support for encrypted session data, see
adodb-cryptsession.php. Enabling encryption is simply a matter of
including adodb-cryptsession.php instead of adodb-session.php.
Setup
There are 3 session management files that you can use:
adodb-session.php : The default
adodb-session-clob.php : Use this if you are storing DATA in clobs
adodb-cryptsession.php : Use this if you want to store encrypted session data in the database
Examples
include('adodb/adodb.inc.php');
$ADODB_SESSION_DRIVER='mysql';
$ADODB_SESSION_CONNECT='localhost';
$ADODB_SESSION_USER ='scott';
$ADODB_SESSION_PWD ='tiger';
$ADODB_SESSION_DB ='sessiondb';
include('adodb/session/adodb-session.php');
session_start();
#
# Test session vars, the following should increment on refresh
#
$_SESSION['AVAR'] += 1;
print "<p>\$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";
To force non-persistent connections, call adodb_session_open() first before session_start():
include('adodb/adodb.inc.php');
$ADODB_SESSION_DRIVER='mysql';
$ADODB_SESSION_CONNECT='localhost';
$ADODB_SESSION_USER ='scott';
$ADODB_SESSION_PWD ='tiger';
$ADODB_SESSION_DB ='sessiondb';
include('adodb/session/adodb-session.php');
adodb_sess_open(false,false,false);
session_start();
The 3rd parameter to adodb_sess_open($path, $sessname, $connectMode) sets the connection method. You can pass in the following:
$connectMode
Connection Method
true
PConnect( )
false
Connect( )
'N'
NConnect( )
'P'
PConnect( )
'C'
Connect( )
To use a encrypted sessions, simply replace the file adodb-session.php:
include('adodb/adodb.inc.php');
$ADODB_SESSION_DRIVER='mysql';
$ADODB_SESSION_CONNECT='localhost';
$ADODB_SESSION_USER ='scott';
$ADODB_SESSION_PWD ='tiger';
$ADODB_SESSION_DB ='sessiondb';
include('adodb/session/adodb-cryptsession.php');
session_start();
And the same technique for adodb-session-clob.php:
include('adodb/adodb.inc.php');
$ADODB_SESSION_DRIVER='mysql';
$ADODB_SESSION_CONNECT='localhost';
$ADODB_SESSION_USER ='scott';
$ADODB_SESSION_PWD ='tiger';
$ADODB_SESSION_DB ='sessiondb';
include('adodb/session/adodb-session-clob.php');
session_start();
An alternative way to set persistant or non-persistent connections is to call the following function before session_start() is called.
ADODB_Session::persist('P'); # 'C' for non-persistent connections
Installation
1. Create this table in your database (MySQL syntax):
create table sessions (
SESSKEY char(32) not null,
EXPIRY int(11) unsigned not null,
EXPIREREF varchar(64),
DATA text not null,
primary key (sesskey)
);
You may want to rename the 'data' field to 'session_data' as
'data' appears to be a reserved word for one or more of the following:
- ANSI SQL
- IBM DB2
- MS SQL Server
- Postgres
- SAP
If you do, then execute:
ADODB_Session::dataFieldName('session_data');
For the adodb-session-clob.php version, create this:
create table sessions (
SESSKEY char(32) not null,
EXPIRY int(11) unsigned not null,
EXPIREREF varchar(64),
DATA CLOB,
primary key (sesskey)
);
2. Then define the following parameters. You can either modify this file, or define them before this file is included:
$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
$ADODB_SESSION_CONNECT='server to connect to';
$ADODB_SESSION_USER ='user';
$ADODB_SESSION_PWD ='password';
$ADODB_SESSION_DB ='database';
$ADODB_SESSION_TBL = 'sessions'; # setting this is optional
When the session is created, $ADODB_SESS_CONN holds the connection object.
3. Recommended is PHP 4.0.6 or later. There are documented session bugs in earlier versions of PHP.
Notifications
You can receive notification when your session is cleaned up by the session garbage collector or
when you call session_destroy().
PHP's session extension will automatically run a special garbage collection function based on
your php.ini session.cookie_lifetime and session.gc_probability settings. This will in turn call
adodb's garbage collection function, which can be setup to do notification.
PHP Session --> ADOdb Session --> Find all recs --> Send --> Delete queued
GC Function GC Function to be deleted notification records
executed at called by for all recs
random time Session Extension queued for deletion
When a session is created, we need to store a value in the session record (in the EXPIREREF field), typically
the userid of the session. Later when the session has expired, just before the record is deleted,
we reload the EXPIREREF field and call the notification function with the value of EXPIREREF, which
is the userid of the person being logged off.
ADOdb uses a global variable $ADODB_SESSION_EXPIRE_NOTIFY that you must predefine before session
start to store the notification configuration.
$ADODB_SESSION_EXPIRE_NOTIFY is an array with 2 elements, the
first being the name of the session variable you would like to store in
the EXPIREREF field, and the 2nd is the notification function's name.
For example, suppose we want to be notified when a user's session has expired,
based on the userid. When the user logs in, we store the id in the global session variable
$USERID. The function name is 'NotifyFn'.
So we define (before session_start() is called):
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
And when the NotifyFn is called (when the session expires), the
$USERID is passed in as the first parameter, eg. NotifyFn($userid, $sesskey). The
session key (which is the primary key of the record in the sessions
table) is the 2nd parameter.
Here is an example of a Notification function that deletes some
records in the database and temporary files:
function NotifyFn($expireref, $sesskey)
{
global $ADODB_SESS_CONN; # the session connection object
$user = $ADODB_SESS_CONN->qstr($expireref);
$ADODB_SESS_CONN->Execute("delete from shopping_cart where user=$user");
system("rm /work/tmpfiles/$expireref/*");
}
NOTE 1: If you have register_globals disabled in php.ini, then you
will have to manually set the EXPIREREF. E.g.
$GLOBALS['USERID'] = GetUserID();
$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');
NOTE 2: If you want to change the EXPIREREF after the session
record has been created, you will need to modify any session variable
to force a database record update.
Neat Notification Tricks
ExpireRef normally holds the user id of the current session.
1. You can then write a session monitor, scanning expireref to see
who is currently logged on.
2. If you delete the sessions record for a specific user, eg.
delete from sessions where expireref = '$USER'
then the user is logged out. Useful for ejecting someone from a
site.
3. You can scan the sessions table to ensure no user
can be logged in twice. Useful for security reasons.
Using Oracle CLOBs
Suppose you are storing the DATA field in a CLOB:
CREATE TABLE sessions (
SESSKEY VARCHAR(32) NOT NULL,
EXPIRY NUMBER(16) NOT NULL,
EXPIREREF VARCHAR(64),
DATA CLOB,
PRIMARY KEY (sesskey)
);
Then your PHP code could look like this:
ADODB_SESSION_DRIVER='oci8';
$ADODB_SESSION_CONNECT=$tnsname;
$ADODB_SESSION_USER ='scott';
$ADODB_SESSION_PWD = 'tiger';
$ADODB_SESSION_DB ='';
$ADODB_SESSION_USE_LOBS = 'clob';
$ADODB_SESSION_TBL = 'sessions';
$ADODB_SESS_DEBUG=0;
include(ADODB_DIR.'/session/adodb-session.php');
ADODB_Session::persist('P'); # use 'C' for non-persistent connects
session_start();
Note that you can set persistance using ADODB_Session::persist('P').
Compression/Encryption Schemes
Since ADOdb 4.05, thanks to Ross Smith, multiple encryption and
compression schemes are supported. Currently, supported are:
MD5Crypt (crypt.inc.php)
MCrypt
Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)
GZip
BZip2
These are stackable. E.g.
ADODB_Session::filter(new ADODB_Compress_Bzip2());
ADODB_Session::filter(new ADODB_Encrypt_MD5());
will compress and then encrypt the record in the database.
adodb_session_regenerate_id()
Dynamically change the current session id with a newly generated one and update database. Currently only
works with cookies. Useful to improve security by reducing the risk of session-hijacking.

== false.
Russian language file contributed by "Cyrill Malevanov" cyrill#malevanov.spb.ru.
Spanish language file contributed by "Horacio Degiorgi" horaciod#codigophp.com.
Error handling in oci8 bugfix - if there was an error in Execute(), then when
calling ErrorNo() and/or ErrorMsg(), the 1st call would return the error, but
the 2nd call would return no error.
Error handling in odbc bugfix. ODBC would always return the last error, even
if it happened 5 queries ago. Now we reset the errormsg to '' and errorno to
0 everytime before CacheExecute() and Execute().
3.70 29 July 2003
Added new SQLite driver. Tested on PHP 4.3 and PHP 5.
Added limited "sapdb" driver support - mainly date support.

The property $emptyDate missing from connection class. Also changed 1903 to
constant (TIMESTAMP_FIRST_YEAR=100). Thx to Sebastiaan van Stijn.
ADOdb speedup optimization - we now return all arrays by reference.
Now DBDate() and DBTimeStamp() now accepts the string 'null' as a parameter.
Suggested by vincent.
Added GetArray() to connection class.

to SQL_CUR_USE_ODBC as the cursor mode, and lastAffectedRows and SelectLimit()
fixes.
The odbc driver's FetchField() field names did not obey ADODB_ASSOC_CASE. Fixed.
Some bugs in adodb_backtrace() fixed.

The odbc_mssql driver now sets CONCAT_NULL_YIELDS_NULL OFF for compat with
mssql driver.
3.50 19 May 2003
Fixed mssql compat with FreeTDS. FreeTDS does not implement mssql_fetch_assoc().
Merged back connection and recordset code into adodb.inc.php.
ADOdb sessions using oracle clobs contributed by achim.gosse#ddd.de. See adodb-session-clob.php.
Added /s modifier to preg_match everywhere, which ensures that regex does not
stop at /n. Thx Pao-Hsi Huang.
Fixed error in metacolumns() for mssql.
Added time format support for SQLDate.
Image => B added to metatype.
MetaType now checks empty($this->blobSize) instead of empty($this).
Datadict has beta support for informix, sybase (mapped to mssql), db2 and generic
(which is a fudge).
BlobEncode for postgresql uses pg_escape_bytea, if available. Needed for compat
with 7.3.
Added $ADODB_LANG, to support multiple languages in MetaErrorMsg().
Datadict can now parse table definition as declarative text.
For DataDict, oci8 autoincrement trigger missing semi-colon. Fixed.
For DataDict, when REPLACE flag enabled, drop sequence in datadict for autoincrement
field in postgres and oci8.s
Postgresql defaults to template1 database if no database defined in connect/pconnect.
We now clear _resultid in postgresql if query fails.
3.40 19 May 2003
Added insert_id for odbc_mssql.
Modified postgresql UpdateBlobFile() because it did not work in safe mode.
Now connection object is passed to raiseErrorFn as last parameter. Needed by
StartTrans().
Added StartTrans() and CompleteTrans(). It is recommended that you do not modify
transOff, but use the above functions.
oci8po now obeys ADODB_ASSOC_CASE settings.
Added virtualized error codes, using PEAR DB equivalents. Requires you to manually
include adodb-error.inc.php yourself, with MetaError() and MetaErrorMsg($errno).
GetRowAssoc for mysql and pgsql were flawed. Fix by Ross Smith.
Added to datadict types I1, I2, I4 and I8. Changed datadict type 'T' to map
to timestamp instead of datetime for postgresql.
Error handling in ExecuteSQLArray(), adodb-datadict.inc.php did not work.
We now auto-quote postgresql connection parameters when building connection
string.
Added session expiry notification.
We now test with odbc mysql - made some changes to odbc recordset constructor.

3.31 17 March 2003
Added row checking for _fetch in postgres.
Added Interval type to MetaType for postgres.
Remapped postgres driver to call postgres7 driver internally.
Adorecordset_array::getarray() did not return array when nRows >= 0.
Postgresql: at times, no error message returned by pg_result_error() but error
message returned in pg_last_error(). Recoded again.
Interbase blob's now use chunking for updateblob.
Move() did not set EOF correctly. Reported by Jorma T.
We properly support mysql timestamp fields when we are creating mysql tables
using the data-dict interface.
Table regex includes backticks character now.
3.30 3 March 2003
Added $ADODB_EXTENSION and $ADODB_COMPAT_FETCH constant.
Made blank1stItem configurable using syntax "value:text" in GetMenu/GetMenu2.
Thx to Gabriel Birke.
Previously ADOdb differed from the Microsoft standard because it did not define
what to set $this->fields when EOF was reached. Now at EOF, ADOdb sets $this->fields
to false for all databases, which is consist with Microsoft's implementation.
Postgresql and mysql have always worked this way (in 3.11 and earlier). If you
are experiencing compatibility problems (and you are not using postgresql nor
mysql) on upgrading to 3.30, try setting the global variables $ADODB_COUNTRECS
= true (which is the default) and $ADODB_FETCH_COMPAT = true (this is a new
global variable).
We now check both pg_result_error and pg_last_error as sometimes pg_result_error
does not display anything. Iman Mayes
We no longer check for magic quotes gpc in Quote().
Misc fixes for table creation in adodb-datadict.inc.php. Thx to iamsure.
Time calculations use adodb_time library for all negative timestamps due to
problems in Red Hat 7.3 or later. Formerly, only did this for Windows.
In mssqlpo, we now check if $sql in _query is a string before we change ||
to +. This is to support prepared stmts.
Move() and MoveLast() internals changed to support to support EOF and $this->fields
change.
Added ADODB_FETCH_BOTH support to mssql. Thx to Angel Fradejas afradejas#mediafusion.es
We now check if link resource exists before we run mysql_escape_string in
qstr().
Before we flock in csv code, we check that it is not a http url.
3.20 17 Feb 2003
Added new Data Dictionary classes for creating tables and indexes. Warning
- this is very much alpha quality code. The API can still change. See adodb/tests/test-datadict.php
for more info.
We now ignore $ADODB_COUNTRECS for mysql, because PHP truncates incomplete
recordsets when mysql_unbuffered_query() is called a second time.
Now postgresql works correctly when $ADODB_COUNTRECS = false.
Changed _adodb_getcount to properly support SELECT DISTINCT.
Discovered that $ADODB_COUNTRECS=true has some problems with prepared queries
- suspect PHP bug.
Now GetOne and GetRow run in $ADODB_COUNTRECS=false mode for better performance.
Added support for mysql_real_escape_string() and pg_escape_string() in qstr().
Added an intermediate variable for mysql _fetch() and MoveNext() to store fields,
to prevent overwriting field array with boolean when mysql_fetch_array() returns
false.
Made arrays for getinsertsql and getupdatesql case-insensitive. Suggested by
Tim Uckun" tim#diligence.com
3.11 11 Feb 2003
Added check for ADODB_NEVER_PERSIST constant in PConnect(). If defined, then
PConnect() will actually call non-persistent Connect().
Modified interbase to properly work with Prepare().
Added $this->ibase_timefmt to allow you to change the date and time format.
Added support for $input_array parameter in CacheFlush().
Added experimental support for dbx, which was then removed when i found that
it was slower than using native calls.
Added MetaPrimaryKeys for mssql and ibase/firebird.
Added new $trim parameter to GetCol and CacheGetCol
Uses updated adodb-time.inc.php 0.06.
3.10 27 Jan 2003

For interbase, added code to handle unlimited number of bind parameters. From
Daniel Hasan daniel#hasan.cl.
Added BlobDecode and UpdateBlob for informix. Thx to Fernando Ortiz.
Added constant ADODB_WINDOWS. If defined, means that running on Windows.
Added constant ADODB_PHPVER which stores php version as a hex num. Removed
$ADODB_PHPVER variable.
Felho Bacsi reported a minor white-space regular expression problem in GetInsertSQL.
Modified ADO to use variant to store _affectedRows
Changed ibase to use base class Replace(). Modified base class Replace() to
support ibase.
Changed odbc to auto-detect when 0 records returned is wrong due to bad odbc
drivers.
Changed mssql to use datetimeconvert ini setting only when 4.30 or later (does
not work in 4.23).
ExecuteCursor($stmt, $cursorname, $params) now accepts a new $params array
of additional bind parameters -- William Lovaton walovaton#yahoo.com.mx.
Added support for sybase_unbuffered_query if ADODB_COUNTRECS == false. Thx
to chuck may.
Fixed FetchNextObj() bug. Thx to Jorma Tuomainen.
We now use SCOPE_IDENTITY() instead of @@IDENTITY for mssql - thx to marchesini#eside.it
Changed postgresql movenext logic to prevent illegal row number from being
passed to pg_fetch_array().
Postgresql initrs bug found by "Bogdan RIPA" bripa#interakt.ro $f1 accidentally
named $f
3.00 6 Jan 2003
Fixed adodb-pear.inc.php syntax error.
Improved _adodb_getcount() to use SELECT COUNT(*) FROM ($sql) for languages
that accept it.
Fixed _adodb_getcount() caching error.
Added sql to retrive table and column info for odbc_mssql.
2.91 3 Jan 2003
Revised PHP version checking to use $ADODB_PHPVER with legal values 0x4000,
0x4050, 0x4200, 0x4300.
Added support for bytea fields and oid blobs in postgres by allowing BlobDecode()
to detect and convert non-oid fields. Also added BlobEncode to postgres when
you want to encode oid blobs.
Added blobEncodeType property for connections to inform phpLens what encoding
method to use for blobs.
Added BlobDecode() and BlobEncode() to base ADOConnection class.
Added umask() to _gencachename() when creating directories.
Added charPage for ado drivers, so you can set the code page.
$conn->charPage = CP_UTF8;
$conn->Connect($dsn);
Modified _seek in mysql to check for num rows=0.
Added to metatypes new informix types for IDS 9.30. Thx Fernando Ortiz.
_maxrecordcount returned in CachePageExecute $rsreturn
Fixed sybase cacheselectlimit( ) problems
MetaColumns() max_length should use precision for types X and C for ms access.
Fixed.
Speedup of odbc non-SELECT sql statements.
Added support in MetaColumns for Wide Char types for ODBC. We halve max_length
if unicode/wide char.
Added 'B' to types handled by GetUpdateSQL/GetInsertSQL.
Fixed warning message in oci8 driver with $persist variable when using PConnect.
2.90 11 Dec 2002
Mssql and mssqlpo and oci8po now support ADODB_ASSOC_CASE.
Now MetaType() can accept a field object as the first parameter.
New $arr = $db->ServerInfo( ) function. Returns $arr['description'] which
is the string description, and $arr['version'].
PostgreSQL and MSSQL speedups for insert/updates.
Implemented new SetFetchMode() that removes the need to use $ADODB_FETCH_MODE.
Each connection has independant fetchMode.
ADODB_ASSOC_CASE now defaults to 2, use native defaults. This is because we
would break backward compat for too many applications otherwise.
Patched encrypted sessions to use replace()
The qstr function supports quoting of nulls when escape character is \
Rewrote bits and pieces of session code to check for time synch and improve
reliability.
Added property ADOConnection::hasTransactions = true/false;
Added CreateSequence and DropSequence functions
Found misplaced MoveNext() in adodb-postgres.inc.php. Fixed.
Sybase SelectLimit not reliable because 'set rowcount' not cached - fixed.
Moved ADOConnection to adodb-connection.inc.php and ADORecordSet to adodb-recordset.inc.php.
This allows us to use doxygen to generate documentation. Doxygen doesn't like
the classes in the main adodb.inc.php file for some mysterious reason.
2.50, 14 Nov 2002
Added transOff and transCnt properties for disabling (transOff = true) and
tracking transaction status (transCnt>0).
Added inputarray handling into _adodb_pageexecute_all_rows - "Ross Smith" RossSmith#bnw.com.
Fixed postgresql inconsistencies in date handling.
Added support for mssql_fetch_assoc.
Fixed $ADODB_FETCH_MODE bug in odbc MetaTables() and MetaPrimaryKeys().

Added support for NConnect() for oracle OCINLogin.
Fixed NumCols() bug.
Changed session handler to use Replace() on write.
Fixed oci8 SelectLimit aggregate function bug again.
Rewrote pivoting code.
2.42, 4 Oct 2002
Fixed ibase_fetch() problem with nulls. Also interbase now does automatic blob
decoding, and is backward compatible. Suggested by Heinz Hombergs heinz#hhombergs.de.
Fixed postgresql MoveNext() problems when called repeatedly after EOF. Also
suggested by Heinz Hombergs.
PageExecute() does not rewrite queries if SELECT DISTINCT is used. Requested
by hans#velum.net
Added additional fixes to oci8 SelectLimit handling with aggregate functions
- thx to Christian Bugge for reporting the problem.
2.41, 2 Oct 2002
Fixed ADODB_COUNTRECS bug in odbc. Thx to Joshua Zoshi jzoshi#hotmail.com.
Increased buffers for adodb-csvlib.inc.php for extremely long sql from 8192
to 32000.
Revised pivottable.inc.php code. Added better support for aggregate fields.
Fixed mysql text/blob types problem in MetaTypes base class - thx to horacio
degiorgi.
Added SQLDate($fmt,$date) function, which allows an sql date format string
to be generated - useful for group by's.
Fixed bug in oci8 SelectLimit when offset>100.
2.40 4 Sept 2002
Added new NLS_DATE_FORMAT property to oci8. Suggested by Laurent NAVARRO ln#altidev.com
Now use bind parameters in oci8 selectlimit for better performance.
Fixed interbase replaceQuote for dialect != 1. Thx to "BEGUIN Pierre-Henri
- INFOCOB" phb#infocob.com.
Added white-space check to QA.
Changed unixtimestamp to support fractional seconds (we always round down/floor
the seconds). Thanks to beezly#beezly.org.uk.
Now you can set the trigger_error type your own user-defined type in adodb-errorhandler.inc.php.
Suggested by Claudio Bustos clbustos#entelchile.net.
Added recordset filters with rsfilter.inc.php.
$conn->_rs2rs does not create a new recordset when it detects it is of type
array. Some trickery there as there seems to be a bug in Zend Engine
Added render_pagelinks to adodb-pager.inc.php. Code by "Pablo Costa" pablo#cbsp.com.br.
MetaType() speedup in adodb.inc.php by using hashing instead of switch. Best
performance if constant arrays are supported, as they are in PHP5.
adodb-session.php now updates only the expiry date if the crc32 check indicates
that the data has not been modified.
2.31 20 Aug 2002
Made changes to pivottable.inc.php due to daniel lucuzaeu's suggestions (we sum the pivottable column if desired).
Fixed ErrorNo() in postgres so it does not depend on _errorMsg property.
Robert Tuttle added support for oracle cursors. See ExecuteCursor().
Fixed Replace() so it works with mysql when updating record where data has not changed. Reported by
Cal Evans (cal#calevans.com).
2.30 1 Aug 2002
Added pivottable.inc.php. Thanks to daniel.lucazeau#ajornet.com for the original
concept.
Added ADOConnection::outp($msg,$newline) to output error and debugging messages. Now
you can override this using the ADODB_OUTP constant and use your own output handler.
Changed == to === for 'null' comparison. Reported by ericquil#yahoo.com
Fixed mssql SelectLimit( ) bug when distinct used.
2.30 1 Aug 2002
New GetCol() and CacheGetCol() from ross#bnw.com that returns the first field as a 1 dim array.
We have an empty recordset, but RecordCount() could return -1. Fixed. Reported by "Jonathan Polansky" jonathan#polansky.com.
We now check for session variable changes using strlen($sessval).crc32($sessval).
Formerly we only used crc32().
Informix SelectLimit() problem with $ADODB_COUNTRECS fixed.
Fixed informix SELECT FIRST x DISTINCT, and not SELECT DISTINCT FIRST x - reported by F Riosa
Now default adodb error handlers ignores error if @ used.
If you set $conn->autoRollback=true, we auto-rollback persistent connections for odbc, mysql, oci8, mssql.
Default for autoRollback is false. No need to do so for postgres.
As interbase requires a transaction id (what a flawed api), we don't do it for interbase.
Changed PageExecute() to use non-greedy preg_match when searching for "FROM" keyword.
2.20 9 July 2002
Added CacheGetOne($secs2cache,$sql), CacheGetRow($secs2cache,$sql), CacheGetAll($secs2cache,$sql).
Added $conn->OffsetDate($dayFraction,$date=false) to generate sql that calcs
date offsets. Useful for scheduling appointments.
Added connection properties: leftOuter, rightOuter that hold left and right
outer join operators.
Added connection property: ansiOuter to indicate whether ansi outer joins supported.
New driver mssqlpo, the portable mssql driver, which converts string
concat operator from || to +.
Fixed ms access bug - SelectLimit() did not support ties - fixed.
Karsten Kraus (Karsten.Kraus#web.de), contributed error-handling code to ADONewConnection.
Unfortunately due to backward compat problems, had to rollback most of the changes.
Added new parameter to GetAssoc() to allow returning an array of key-value pairs,
ignoring any additional columns in the recordset. Off by default.
Corrected mssql $conn->sysDate to return only date using convert().
CacheExecute() improved debugging output.
Changed rs2html() so newlines are converted to BR tags. Also optimized rs2html() based
on feedback by "Jerry Workman" jerry#mtncad.com.
Added support for Replace() with Interbase, using DELETE and INSERT.
Some minor optimizations (mostly removing & references when passing arrays).
Changed GenID() to allows id's larger than the size of an integer.
Added force_session property to oci8 for better updateblob() support.
Fixed PageExecute() which did not work properly with sql containing GROUP BY.
2.12 12 June 2002
Added toexport.inc.php to export recordsets in CSV and tab-delimited format.
CachePageExecute() does not work - fixed - thx John Huong.
Interbase aliases not set properly in FetchField() - fixed. Thx Stefan Goethals.
Added cache property to adodb pager class. The number of secs to cache recordsets.
SQL rewriting bug in pageexecute() due to skipping of newlines due to missing /s modifier. Fixed.
Max size of cached recordset due to a bug was 256000 bytes. Fixed.
Speedup of 1st invocation of CacheExecute() by tuning code.
We compare $rewritesql with $sql in pageexecute code in case of rewrite failure.
2.11 7 June 2002
Fixed PageExecute() rewrite sql problem - COUNT(*) and ORDER BY don't go together with
mssql, access and postgres. Thx to Alexander Zhukov alex#unipack.ru
DB2 support for CHARACTER type added - thx John Huong huongch#bigfoot.com
For ado, $argProvider not properly checked. Fixed - kalimero#ngi.it
Added $conn->Replace() function for update with automatic insert if the record does not exist.
Supported by all databases except interbase.
2.10 4 June 2002
Added uniqueSort property to indicate mssql ORDER BY cols must be unique.
Optimized session handler by crc32 the data. We only write if session data has changed.
adodb_sess_read in adodb-session.php now returns ''correctly - thanks to Jorma Tuomainen, webmaster#wizactive.com
Mssql driver did not throw EXECUTE errors correctly because ErrorMsg() and ErrorNo() called in wrong order.
Pointed out by Alexios Fakos. Fixed.
Changed ado to use client cursors. This fixes BeginTran() problems with ado.
Added handling of timestamp type in ado.
Added to ado_mssql support for insert_id() and affected_rows().
Added support for mssql.datetimeconvert=0, available since php 4.2.0.
Made UnixDate() less strict, so that the time is ignored if present.
Changed quote() so that it checks for magic_quotes_gpc.
Changed maxblobsize for odbc to default to 64000.
2.00 13 May 2002
Added drivers informix72 for pre-7.3 versions, and oci805 for
oracle 8.0.5, and postgres64 for postgresql 6.4 and earlier. The postgres and postgres7 drivers
are now identical.
Interbase now partially supports ADODB_FETCH_BOTH, by defaulting to ASSOC mode.
Proper support for blobs in mssql. Also revised blob support code
is base class. Now UpdateBlobFile() calls UpdateBlob() for consistency.
Added support for changed odbc_fetch_into api in php 4.2.0
with $conn->_has_stupid_odbc_fetch_api_change.
Fixed spelling of tablock locking hint in GenID( ) for mssql.
Added RowLock( ) to several databases, including oci8, informix, sybase, etc.
Fixed where error in mssql RowLock().
Added sysDate and sysTimeStamp properties to most database drivers. These are the sql
functions/constants for that database that return the current date and current timestamp, and
are useful for portable inserts and updates.
Support for RecordCount() caused date handling in sybase and mssql to break.
Fixed, thanks to Toni Tunkkari, by creating derived classes for ADORecordSet_array for
both databases. Generalized using arrayClass property. Also to support RecordCount(),
changed metatype handling for ado drivers. Now the type returned in FetchField
is no longer a number, but the 1-char data type returned by MetaType.
At the same time, fixed a lot of date handling. Now mssql support dmy and mdy date formats.
Also speedups in sybase and mssql with preg_match and ^ in date/timestamp handling.
Added support in sybase and mssql for 24 hour clock in timestamps (no AM/PM).
Extensive revisions to informix driver - thanks to Samuel CARRIERE samuel_carriere#hotmail.com
Added $ok parameter to CommitTrans($ok) for easy rollbacks.
Fixed odbc MetaColumns and MetaTables to save and restore $ADODB_FETCH_MODE.
Some odbc drivers did not call the base connection class constructor. Fixed.
Fixed regex for GetUpdateSQL() and GetInsertSQL() to support more legal character combinations.
1.99 21 April 2002
Added emulated RecordCount() to all database drivers if $ADODB_COUNTRECS = true
(which it is by default). Inspired by Cristiano Duarte (cunha17#uol.com.br).
Unified stored procedure support for mssql and oci8. Parameter() and PrepareSP()
functions implemented.
Added support for SELECT FIRST in informix, modified hasTop property to support
this.
Changed csv driver to handle updates/deletes/inserts properly (when Execute() returns true).
Bind params also work now, and raiseErrorFn with csv driver. Added csv driver to QA process.
Better error checking in oci8 UpdateBlob() and UpdateBlobFile().
Added TIME type to MySQL - patch by Manfred h9125297#zechine.wu-wien.ac.at
Prepare/Execute implemented for Interbase/Firebird
Changed some regular expressions to be anchored by /^ $/ for speed.
Added UnixTimeStamp() and UnixDate() to ADOConnection(). Now these functions
are in both ADOConnection and ADORecordSet classes.
Empty recordsets were not cached - fixed.
Thanks to Gaetano Giunta (g.giunta#libero.it) for the oci8 code review. We
didn't agree on everything, but i hoped we agreed to disagree!
1.90 6 April 2002
Now all database drivers support fetch modes ADODB_FETCH_NUM and ADODB_FETCH_ASSOC, though
still not fully tested. Eg. Frontbase, Sybase, Informix.
NextRecordSet() support for mssql. Contributed by "Sven Axelsson" sven.axelsson#bokochwebb.se
Added blob support for SQL Anywhere. Contributed by Wade Johnson wade#wadejohnson.de
Fixed some security loopholes in server.php. Server.php also supports fetch mode.
Generalized GenID() to support odbc and mssql drivers. Mssql no longer generates GUID's.
Experimental RowLock($table,$where) for mssql.
Properly implemented Prepare() in oci8 and ODBC.
Added Bind() support to oci8 to support Prepare().
Improved error handler. Catches CacheExecute() and GenID() errors now.
Now if you are running php from the command line, debugging messages do not output html formating.
Not 100% complete, but getting there.
1.81 22 March 2002
Restored default $ADODB_FETCH_MODE = ADODB_FETCH_DEFAULT for backward compatibility.
SelectLimit for oci8 improved - Our FIRST_ROWS optimization now does not overwrite existing hint.
New Sybase SQL Anywhere driver. Contributed by Wade Johnson wade#wadejohnson.de
1.80 15 March 2002
Redesigned directory structure of ADOdb files. Added new driver directory where
all database drivers reside.
Changed caching algorithm to create subdirectories. Now we scale better.
Informix driver now supports insert_id(). Contribution by "Andrea Pinnisi" pinnisi#sysnet.it
Added experimental ISO date and FetchField support for informix.
Fixed a quoting bug in Execute() with bind parameters, causing problems with blobs.
Mssql driver speedup by 10-15%.
Now in CacheExecute($secs2cache,$sql,...), $secs2cache is optional. If missing, it will
take the value defined in $connection->cacheSecs (default is 3600 seconds). Note that
CacheSelectLimit(), the secs2cache is still compulsory - sigh.
Sybase SQL Anywhere driver (using ODBC) contributed by Wade Johnson wade#wadejohnson.de
1.72 8 March 2002
Added @ when returning Fields() to prevent spurious error - "Michael William Miller" mille562#pilot.msu.edu
MetaDatabases() for postgres contributed by Phil pamelant#nerim.net
Mitchell T. Young (mitch#youngfamily.org) contributed informix driver.
Fixed rs2html() problem. I cannot reproduce, so probably a problem with pre PHP 4.1.0 versions,
when supporting new ADODB_FETCH_MODEs.
Mattia Rossi (mattia#technologist.com) contributed BlobDecode() and UpdateBlobFile() for postgresql
using the postgres specific pg_lo_import()/pg_lo_open() - i don't use them but hopefully others will
find this useful. See
for an example of usage.
Added UpdateBlobFile() for uploading files to a database.
Made UpdateBlob() compatible with oci8po driver.
Added noNullStrings support to oci8 driver. Oracle changes all ' ' strings to nulls,
so you need to set strings to ' ' to prevent the nullifying of strings. $conn->noNullStrings = true;
will do this for you automatically. This is useful when you define a char column as NOT NULL.
Fixed UnixTimeStamp() bug - wasn't setting minutes and seconds properly. Patch from Agusti Fita i Borrell agusti#anglatecnic.com.
Toni Tunkkari added patch for sybase dates. Problem with spaces in day part of date fixed.
1.71 18 Jan 2002
Sequence start id support. Now $conn->Gen_ID('seqname', 50) to start sequence from 50.
CSV driver fix for selectlimit, from Andreas - akaiser#vocote.de.
Gam3r spotted that a global variable was undefined in the session handler.
Mssql date regex had error. Fixed - reported by Minh Hoang vb_user#yahoo.com.
DBTimeStamp() and DBDate() now accept iso dates and unix timestamps. This means
that the PostgreSQL handling of dates in GetInsertSQL() and GetUpdateSQL() can
be removed. Also if these functions are passed '' or null or false, we return a SQL null.
GetInsertSQL() and GetUpdateSQL() now accept a new parameter, $magicq to
indicate whether quotes should be inserted based on magic quote settings - suggested by
dj#4ict.com.
Reformated docs slightly based on suggestions by Chris Small.
1.65 28 Dec 2001
Fixed borland_ibase class naming bug.
Now instead of using $rs->fields[0] internally, we use reset($rs->fields) so
that we are compatible with ADODB_FETCH_ASSOC mode. Reported by Nico S.
Changed recordset constructor and _initrs() for oci8 so that it returns the field definitions even
if no rows in the recordset. Reported by Rick Hickerson (rhickers#mv.mv.com).
Improved support for postgresql in GetInsertSQL and GetUpdateSQL by
"mike" mike#partner2partner.com and "Ryan Bailey" rebel#windriders.com
1.64 20 Dec 2001

Added more tests to test suite to cover ADODB_FETCH_* and ADODB_ERROR_HANDLER.
Added firebird (ibase) driver
Added borland_ibase driver for interbase 6.5
1.63 13 Dec 2001
Absolute to the adodb-lib.inc.php file not set properly. Fixed.
1.62 11 Dec 2001
Major speedup of ADOdb for low-end web sites by reducing the php code loading and compiling
cycle. We conditionally compile not so common functions.
Moved csv code to adodb-csvlib.inc.php to reduce adodb.inc.php parsing. This file
is loaded only when the csv/proxy driver is used, or CacheExecute() is run.
Also moved PageExecute(), GetSelectSQL() and GetUpdateSQL() core code to adodb-lib.inc.php.
This reduced the 70K main adodb.inc.php file to 55K, and since at least 20K of the file
is comments, we have reduced 50K of code in adodb.inc.php to 35K. There
should be 35% reduction in memory and thus 35% speedup in compiling the php code for the
main adodb.inc.php file.
Highly tuned SelectLimit() for oci8 for massive speed improvements on large files.
Selecting 20 rows starting from the 20,000th row of a table is now 7 times faster.
Thx to Tomas V V Cox.
Allow . and # in table definitions in GetInsertSQL and GetUpdateSQL.
See ADODB_TABLE_REGEX constant. Thx to Ari Kuorikoski.
Added ADODB_PREFETCH_ROWS constant, defaulting to 10. This determines the number
of records to prefetch in a SELECT statement. Only used by oci8.
Added high portability Oracle class called oci8po. This uses ? for bind variables, and
lower cases column names.
Now all database drivers support $ADODB_FETCH_MODE, including interbase, ado, and odbc:
ADODB_FETCH_NUM and ADODB_FETCH_ASSOC. ADODB_FETCH_BOTH is not fully implemented for all
database drivers.
1.61 Nov 2001
Added PO_RecordCount() and PO_Insert_ID(). PO stands for portable. Pablo Roca
[pabloroca#mvps.org]
GenID now returns 0 if not available. Safer is that you should check $conn->hasGenID
for availability.
M'soft ADO we now correctly close recordset in _close() peterd#telephonetics.co.uk
MSSQL now supports GenID(). It generates a 16-byte GUID from mssql newid()
function.
Changed ereg_replace to preg_replace in SelectLimit. This is a fix for mssql.
Ereg doesn't support t or n! Reported by marino Carlos xaplo#postnuke-espanol.org
Added $recordset->connection. This is the ADOConnection object for the recordset.
Works with cached and normal recordsets. Surprisingly, this had no affect on performance!
1.54 15 Nov 2001
Fixed some more bugs in PageExecute(). I am getting sick of bug in this and will have to
reconsider my QA here. The main issue is that I don't use PageExecute() and
to check whether it is working requires a visual inspection of the html generated currently.
It is possible to write a test script but it would be quite complicated :(
More speedups of SelectLimit() for DB2, Oci8, access, vfp, mssql.
1.53 7 Nov 2001
Added support for ADODB_FETCH_ASSOC for ado and odbc drivers.
Tuned GetRowAssoc(false) in postgresql and mysql.
Stephen Van Dyke contributed ADOdb icon, accepted with some minor mods.
Enabled Affected_Rows() for postgresql
Speedup for Concat() using implode() - Benjamin Curtis ben_curtis#yahoo.com
Fixed some more bugs in PageExecute() to prevent infinite loops
1.52 5 Nov 2001
Spelling error in CacheExecute() caused it to fail. $ql should be $sql in line 625!
Added fixes for parsing [ and ] in GetUpdateSQL().
1.51 5 Nov 2001
Oci8 SelectLimit() speedup by using OCIFetch().
Oci8 was mistakenly reporting errors when $db->debug = true.
If a connection failed with ODBC, it was not correctly reported - fixed.
_connectionID was inited to -1, changed to false.
Added $rs->FetchRow(), to simplify API, ala PEAR DB
Added PEAR DB compat mode, which is still faster than PEAR! See adodb-pear.inc.php.
Removed postgres pconnect debugging statement.
1.50 31 Oct 2001
ADOdbConnection renamed to ADOConnection, and ADOdbFieldObject to ADOFieldObject.
PageExecute() now checks for empty $rs correctly, and the errors in the docs on this subject have been fixed.
odbc_error() does not return 6 digit error correctly at times. Implemented workaround.
Added ADORecordSet_empty class. This will speedup INSERTS/DELETES/UPDATES because the return
object created is much smaller.
Added Prepare() to odbc, and oci8 (but doesn't work properly for oci8 still).
Made pgsql a synonym for postgre7, and changed SELECT LIMIT to use OFFSET for compat with
postgres 7.2.
Revised adodb-cryptsession.php thanks to Ari.
Set resources to false on _close, to force freeing of resources.
Added adodb-errorhandler.inc.php, adodb-errorpear.inc.php and raiseErrorFn on Freek's urging.
GetRowAssoc($toUpper=true): $toUpper added as default.
Errors when connecting to a database were not captured formerly. Now we do it correctly.
1.40 19 September 2001
PageExecute() to implement page scrolling added. Code and idea by Iván Oliva.
Some minor postgresql fixes.
Added sequence support using GenID() for postgresql, oci8, mysql, interbase.
Added UpdateBlob support for interbase (untested).
Added encrypted sessions (see adodb-cryptsession.php). By Ari Kuorikoski <kuoriari#finebyte.com>
1.31 21 August 2001
Many bug fixes thanks to "GaM3R (Cameron)" <gamr#outworld.cx>. Some session changes due to Gam3r.
Fixed qstr() to quote also.
rs2html() now pretty printed.
Jonathan Younger jyounger#unilab.com contributed the great idea GetUpdateSQL() and GetInsertSQL() which
generates SQL to update and insert into a table from a recordset. Modify the recordset fields
array, then can this function to generate the SQL (the SQL is not executed).
"Nicola Fankhauser" <nicola.fankhauser#couniq.com> found some bugs in date handling for mssql.
Added minimal Oracle support for LOBs. Still under development.
Added $ADODB_FETCH_MODE so you can control whether recordsets return arrays which are
numeric, associative or both. This is a global variable you set. Currently only MySQL, Oci8, Postgres
drivers support this.
PostgreSQL properly closes recordsets now. Reported by several people.
Added UpdateBlob() for Oracle. A hack to make it easier to save blobs.
Oracle timestamps did not display properly. Fixed.
1.20 6 June 2001
Now Oracle can connect using tnsnames.ora or server and service name
Extensive Oci8 speed optimizations.
Oci8 code revised to support variable binding, and /*+ FIRST_ROWS */ hint.
Worked around some 4.0.6 bugs in odbc_fetch_into().
Paolo S. Asioli paolo.asioli#libero.it suggested GetRowAssoc().
Escape quotes for oracle wrongly set to '. Now '' is used.
Variable binding now works in ODBC also.
Jumped to version 1.20 because I don't like 13 :-)
1.12 6 June 2001
Changed $ADODB_DIR to ADODB_DIR constant to plug a security loophole.
Changed _close() to close persistent connections also. Prevents connection leaks.
Major revision of oracle and oci8 drivers.
Added OCI_RETURN_NULLS and OCI_RETURN_LOBS to OCIFetchInto(). BLOB, CLOB and VARCHAR2 recognition
in MetaType() improved. MetaColumns() returns columns in correct sort order.
Interbase timestamp input format was wrong. Fixed.
1.11 20 May 2001
Improved file locking for Windows.
Probabilistic flushing of cache to avoid avalanche updates when cache timeouts.
Cached recordset timestamp not saved in some scenarios. Fixed.
1.10 19 May 2001
Added caching. CacheExecute() and CacheSelectLimit().
Added csv driver. See .
Fixed SelectLimit(), SELECT TOP not working under certain circumstances.
Added better Frontbase support of MetaTypes() by Frank M. Kromann.
1.01 24 April 2001
Fixed SelectLimit bug. not quoted properly.
SelectLimit: SELECT TOP -1 * FROM TABLE not support by Microsoft. Fixed.
GetMenu improved by glen.davies#cce.ac.nz to support multiple hilited items
FetchNextObject() did not work with only 1 record returned. Fixed bug reported by $tim#orotech.net
Fixed mysql field max_length problem. Fix suggested by Jim Nicholson (jnich#att.com)
1.00 16 April 2001
Given some brilliant suggestions on how to simplify ADOdb by akul. You no longer need to
setup $ADODB_DIR yourself, and ADOLoadCode() is automatically called by ADONewConnection(),
simplifying the startup code.
FetchNextObject() added. Suggested by Jakub Marecek. This makes FetchObject() obsolete, as
this is more flexible and powerful.
Misc fixes to SelectLimit() to support Access (top must follow distinct) and Fields()
in the array recordset. From Reinhard Balling.
0.96 27 Mar 2001
ADOConnection Close() did not return a value correctly. Thanks to akul#otamedia.com.
When the horrible magic_quotes is enabled, back-slash () is changed to double-backslash (\).
This doesn't make sense for Microsoft/Sybase databases. We fix this in qstr().
Fixed Sybase date problem in UnixDate() thanks to Toni Tunkkari. Also fixed MSSQL problem
in UnixDate() - thanks to milhouse31#hotmail.com.
MoveNext() moved to leaf classes for speed in MySQL/PostgreSQL. 10-15% speedup.
Added null handling in bindInputArray in Execute() -- Ron Baldwin suggestion.
Fixed some option tags. Thanks to john#jrmstudios.com.
0.95 13 Mar 2001
Added postgres7 database driver which supports LIMIT and other version 7 stuff in the future.
Added SelectLimit to ADOConnection to simulate PostgreSQL's "select * from table limit 10 offset 3".
Added helper function GetArrayLimit() to ADORecordSet.
Fixed mysql metacolumns bug. Thanks to Freek Dijkstra (phpeverywhere#macfreek.com).
Also many PostgreSQL changes by Freek. He almost rewrote the whole PostgreSQL driver!
Added fix to input parameters in Execute for non-strings by Ron Baldwin.
Added new metatype, X for TeXt. Formerly, metatype B for Blob also included
text fields. Now 'B' is for binary/image data. 'X' for textual data.
Fixed $this->GetArray() in GetRows().
Oracle and OCI8: 1st parameter is always blank -- now warns if it is filled.
Now hasLimit and hasTop added to indicate whether
SELECT * FROM TABLE LIMIT 10 or SELECT TOP 10 * FROM TABLE are supported.
0.94 04 Feb 2001
Added ADORecordSet::GetRows() for compatibility with Microsoft ADO. Synonym for GetArray().

Interbase driver did not call ibase_pconnect(). Fixed.
0.93 18 Jan 2002
Fixed GetMenu bug.
Simplified Interbase commit and rollback.
Default behaviour on closing a connection is now to rollback all active transactions.
Added field object handling for array recordset for future XML compatibility.
Added arr2html() to convert array to html table.
0.92 2 Jan 2002
Interbase Commit and Rollback should be working again.
Changed initialisation of ADORecordSet. This is internal and should not affect users. We
are doing this to support cached recordsets in the future.
Implemented ADORecordSet_array class. This allows you to simulate a database recordset
with an array.
Added UnixDate() and UnixTimeStamp() to ADORecordSet.
0.91 21 Dec 2000
Fixed ODBC so ErrorMsg() is working.
Worked around ADO unrecognised null (0x1) value problem in COM.
Added Sybase support for FetchField() type
Removed debugging code and unneeded html from various files

0.70 15 Nov 2000
Calls by reference have been removed (call_time_pass_reference=Off) to ensure compatibility with future versions of PHP,
except in Oracle 7 driver due to a bug in php_oracle.dll.
PostgreSQL database driver contributed by Alberto Cerezal (acerezalp#dbnet.es).
Oci8 driver for Oracle 8 contributed by George Fourlanos (fou#infomap.gr).
Added mysqlt database driver to support MySQL 3.23 which has transaction
support.
Oracle default date format (DD-MON-YY) did not match ADOdb default date format (which is YYYY-MM-DD). Use ALTER SESSION to force the default date.
Error message checking is now included in test suite.
MoveNext() did not check EOF properly -- fixed.
0.60 Nov 8 2000
Fixed some constructor bugs in ODBC and ADO. Added ErrorNo function to ADOConnection

ADOdb Library for PHP
ADOdb is a suite of database libraries that allow you to connect to multiple
databases in a portable manner. Download from
This allows you to query, update and insert records using a portable API.
- The ADOdb data dictionary docs are at docs-datadict.htm.
This allows you to create database tables and indexes in a portable manner.
- The ADOdb database performance monitoring docs are at docs-perf.htm.
This allows you to perform health checks, tune and monitor your database.
- The ADOdb database-backed session docs are at docs-session.htm.
Installation
Make sure you are running PHP4.0.4 or later. Unpack all the files into a directory accessible by your webserver.
To test, try modifying some of the tutorial examples. Make sure you customize the connection settings correctly. You can debug using:
<?php
include('adodb/adodb.inc.php');
$db = ADONewConnection($driver); # eg. 'mysql' or 'oci8'
$db->debug = true;
$db->Connect($server, $user, $password, $database);
$rs = $db->Execute('select * from some_small_table');
print "<pre>";
print_r($rs->GetRows());
print "</pre>";
?>

Tips on Writing Portable SQL for Multiple Databases for PHP
ӣƵ
Tips on Writing Portable SQL
Updated 6 Oct 2006. Added OffsetDate example.
Updated 18 Sep 2003. Added Portable Native SQL section.
If you are writing an application that is used in multiple environments and
operating systems, you need to plan to support multiple databases. This article
is based on my experiences with multiple database systems, stretching from 4th
Dimension in my Mac days, to the databases I currently use, which are: Oracle,
FoxPro, Access, MS SQL Server and MySQL. Although most of the advice here applies
to using SQL with Perl, Python and other programming languages, I will focus on PHP and how
the database abstraction library
offers some solutions.
Most database vendors practice product lock-in. The best or fastest way to
do things is often implemented using proprietary extensions to SQL. This makes
it extremely hard to write portable SQL code that performs well under all conditions.
When the first ANSI committee got together in 1984 to standardize SQL, the database
vendors had such different implementations that they could only agree on the
core functionality of SQL. Many important application specific requirements
were not standardized, and after so many years since the ANSI effort began,
it looks as if much useful database functionality will never be standardized.
Even though ANSI-92 SQL has codified much more, we still have to implement portability
at the application level.
Selects
The SELECT statement has been standardized to a great degree. Nearly every
database supports the following:
SELECT [cols] FROM [tables]
[WHERE conditions]
[GROUP BY cols]
[HAVING conditions]
[ORDER BY cols]
But so many useful techniques can only be implemented by using proprietary
extensions. For example, when writing SQL to retrieve the first 10 rows for
paging, you could write...
Database
SQL Syntax
DB2
select * from table fetch first 10 rows only
Informix
select first 10 * from table
Microsoft SQL Server and Access
select top 10 * from table
MySQL and PostgreSQL
select * from table limit 10
Oracle 8i
select * from (select * from table) where rownum <= 10
This feature of getting a subset of data is so useful that in the PHP class
library ADOdb, we have a SelectLimit( ) function that allows you to hide the
implementation details within a function that will rewrite your SQL for you:
$connection->SelectLimit('select * from table', 10);
Selects: Fetch Modes
PHP allows you to retrieve database records as arrays. You can choose to have
the arrays indexed by field name or number. However different low-level PHP
database drivers are inconsistent in their indexing efforts. ADOdb allows you
to determine your prefered mode. You set this by setting the variable $ADODB_FETCH_MODE
to either of the constants ADODB_FETCH_NUM (for numeric indexes) or ADODB_FETCH_ASSOC
(using field names as an associative index).
The default behaviour of ADOdb varies depending on the database you are using.
For consistency, set the fetch mode to either ADODB_FETCH_NUM (for speed) or
ADODB_FETCH_ASSOC (for convenience) at the beginning of your code.
Selects: Counting Records
Another problem with SELECTs is that some databases do not return the number
of rows retrieved from a select statement. This is because the highest performance
databases will return records to you even before the last record has been found.
In ADOdb, RecordCount( ) returns the number of rows returned, or will emulate
it by buffering the rows and returning the count after all rows have been returned.
This can be disabled for performance reasons when retrieving large recordsets
by setting the global variable $ADODB_COUNTRECS = false. This variable is checked
every time a query is executed, so you can selectively choose which recordsets
to count.
If you prefer to set $ADODB_COUNTRECS = false, ADOdb still has the PO_RecordCount(
) function. This will return the number of rows, or if it is not found, it will
return an estimate using SELECT COUNT(*):
$rs = $db->Execute("select * from table where state=$state");
$numrows = $rs->PO_RecordCount('table', "state=$state");
Selects: Locking
SELECT statements are commonly used to implement row-level locking of tables.
Other databases such as Oracle, Interbase, PostgreSQL and MySQL with InnoDB
do not require row-level locking because they use versioning to display data
consistent with a specific point in time.
Currently, I recommend encapsulating the row-level locking in a separate function,
such as RowLock($table, $where):
$connection->BeginTrans( );
$connection->RowLock($table, $where);
# some operation
if ($ok) $connection->CommitTrans( );
else $connection->RollbackTrans( );
Selects: Outer Joins
Not all databases support outer joins. Furthermore the syntax for outer joins
differs dramatically between database vendors. One portable (and possibly slower)
method of implementing outer joins is using UNION.
For example, an ANSI-92 left outer join between two tables t1 and t2 could
look like:
SELECT t1.col1, t1.col2, t2.cola
FROM t1 LEFT JOIN t2 ON t1.col = t2.col
This can be emulated using:
SELECT t1.col1, t1.col2, t2.cola FROM t1, t2
WHERE t1.col = t2.col
UNION ALL
SELECT col1, col2, null FROM t1
WHERE t1.col not in (select distinct col from t2)
Since ADOdb 2.13, we provide some hints in the connection object as to legal
join variations. This is still incomplete and sometimes depends on the database
version you are using, but is useful as a general guideline:
$conn->leftOuter: holds the
operator used for left outer joins (eg. '*='), or false if not known or not
available.
$conn->rightOuter: holds the
operator used for right outer joins (eg '=*'), or false if not known or not
available.
$conn->ansiOuter: boolean
that if true means that ANSI-92 style outer joins are supported, or false if
not known.
Inserts
When you create records, you need to generate unique id's for each record.
There are two common techniques: (1) auto-incrementing columns and (2) sequences.
Auto-incrementing columns are supported by MySQL, Sybase and Microsoft Access
and SQL Server. However most other databases do not support this feature. So
for portability, you have little choice but to use sequences. Sequences are
special functions that return a unique incrementing number every time you call
it, suitable to be used as database keys. In ADOdb, we use the GenID( ) function.
It has takes a parameter, the sequence name. Different tables can have different
sequences.
$id = $connection->GenID('sequence_name');
$connection->Execute("insert into table (id, firstname, lastname)
values ($id, $firstname, $lastname)");
For databases that do not support sequences natively, ADOdb emulates sequences
by creating a table for every sequence.
Binding
Binding variables in an SQL statement is another tricky feature. Binding is
useful because it allows pre-compilation of SQL. When inserting multiple records
into a database in a loop, binding can offer a 50% (or greater) speedup. However
many databases such as Access and MySQL do not support binding natively and
there is some overhead in emulating binding. Furthermore, different databases
(specificly Oracle!) implement binding differently. My recommendation is to
use binding if your database queries are too slow, but make sure you are using
a database that supports it like Oracle.
ADOdb supports portable Prepare/Execute with:
$stmt = $db->Prepare('select * from customers where custid=? and state=?');
$rs = $db->Execute($stmt, array($id,'New York'));
Oracle uses named bind placeholders, not "?", so to support portable binding, we have Param() that generates
the correct placeholder (available since ADOdb 3.92):
$sql = 'insert into table (col1,col2) values ('.$DB->Param('a').','.$DB->Param('b').')';
# generates 'insert into table (col1,col2) values (?,?)'
# or 'insert into table (col1,col2) values (:a,:b)'
$stmt = $DB->Prepare($sql);
$stmt = $DB->Execute($stmt,array('one','two'));
Portable Native SQL
ADOdb provides the following functions for portably generating SQL functions
as strings to be merged into your SQL statements (some are only available since
ADOdb 3.92):
Function
Description
DBDate($date)
Pass in a UNIX timestamp or ISO date and it will convert it to a date
string formatted for INSERT/UPDATE
DBTimeStamp($date)
Pass in a UNIX timestamp or ISO date and it will convert it to a timestamp
string formatted for INSERT/UPDATE
SQLDate($date, $fmt)
Portably generate a date formatted using $fmt mask, for use in SELECT
statements.
OffsetDate($date, $ndays)
Portably generate a $date offset by $ndays.
Concat($s1, $s2, ...)
Portably concatenate strings. Alternatively, for mssql use mssqlpo driver,
which allows || operator.
IfNull($fld, $replaceNull)
Returns a string that is the equivalent of MySQL IFNULL or Oracle NVL.
Param($name)
Generates bind placeholders, using ? or named conventions as appropriate.
$db->sysDate Property that holds the SQL function that returns today's date
$db->sysTimeStamp Property that holds the SQL function that returns the current
timestamp (date+time).
$db->concat_operator Property that holds the concatenation operator
$db->length Property that holds the name of the SQL strlen function.
$db->upperCase Property that holds the name of the SQL strtoupper function.
$db->random Property that holds the SQL to generate a random number between 0.00 and 1.00.
$db->substr Property that holds the name of the SQL substring function.
DDL and Tuning
There are database design tools such as ERWin or Dezign that allow you to generate data definition language commands such as ALTER TABLE or CREATE INDEX from Entity-Relationship diagrams.
However if you prefer to use a PHP-based table creation scheme, adodb provides you with this feature. Here is the code to generate the SQL to create a table with:
- Auto-increment primary key 'ID',
- The person's 'NAME' VARCHAR(32) NOT NULL and defaults to '',
- The date and time of record creation 'CREATED',
- The person's 'AGE', defaulting to 0, type NUMERIC(16).
Also create a compound index consisting of 'NAME' and 'AGE':
$datadict = NewDataDictionary($connection);
$flds = "
ID I AUTOINCREMENT PRIMARY,
NAME C(32) DEFAULT '' NOTNULL,
CREATED T DEFTIMESTAMP,
AGE N(16) DEFAULT 0
";
$sql1 = $datadict->CreateTableSQL('tabname', $flds);
$sql2 = $datadict->CreateIndexSQL('idx_name_age', 'tabname', 'NAME,AGE');
Data Types
Stick to a few data types that are available in most databases. Char, varchar
and numeric/number are supported by most databases. Most other data types (including
integer, boolean and float) cannot be relied on being available. I recommend
using char(1) or number(1) to hold booleans.
Different databases have different ways of representing dates and timestamps/datetime.
ADOdb attempts to display all dates in ISO (YYYY-MM-DD) format. ADOdb also provides
DBDate( ) and DBTimeStamp( ) to convert dates to formats that are acceptable
to that database. Both functions accept Unix integer timestamps and date strings
in ISO format.
$date1 = $connection->DBDate(time( ));
$date2 = $connection->DBTimeStamp('2002-02-23 13:03:33');
We also provide functions to convert database dates to Unix timestamps:
$unixts = $recordset->UnixDate('#2002-02-30#'); # MS Access date =gt; unix timestamp
For date calculations, we have OffsetDate which allows you to calculate dates such as yesterday and next week in a RDBMS independant fashion. For example, if we want to set a field to 6 hour from now, use:
$sql = 'update table set dtimefld='.$db->OffsetDate($db->sysTimeStamp, 6/24).' where ...';
The maximum length of a char/varchar field is also database specific. You can
only assume that field lengths of up to 250 characters are supported. This is
normally impractical for web based forum or content management systems. You
will need to be familiar with how databases handle large objects (LOBs). ADOdb
implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to
update fields holding Binary Large Objects (eg. pictures) and Character Large
Objects (eg. HTML articles):
# for oracle
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1,empty_blob())');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
# non-oracle databases
$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)');
$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
Null handling is another area where differences can occur. This is a mine-field,
because 3-value logic is tricky.
In general, I avoid using nulls except for dates and default all my numeric
and character fields to 0 or the empty string. This maintains consistency with
PHP, where empty strings and zero are treated as equivalent, and avoids SQL
ambiguities when you use the ANY and EXISTS operators. However if your database
has significant amounts of missing or unknown data, using nulls might be a good
idea.
ADOdb also supports a portable .

You say eether and I say eyether,
You say neether and I say nyther;
Eether, eyether, neether, nyther -
Let's call the whole thing off !

I love this song, especially the version with Louis Armstrong and Ella singing
duet. It is all about how hard it is for two people in love to be compatible
with each other. It's about compromise and finding a common ground, and that's
what this article is all about.
PHP is all about creating dynamic web-sites with the least fuss and the most
fun. To create these websites we need to use databases to retrieve login information,
to splash dynamic news onto the web page and store forum postings. So let's
say we were using the popular MySQL database for this. Your company has done
such a fantastic job that the Web site is more popular than your wildest dreams.
You find that MySQL cannot scale to handle the workload; time to switch databases.
Unfortunately in PHP every database is accessed slightly differently. To connect
to MySQL, you would use mysql_connect(); when you decide to upgrade to
Oracle or Microsoft SQL Server, you would use ocilogon() or mssql_connect()
respectively. What is worse is that the parameters you use for the different
connect functions are different also.. One database says po-tato, the other
database says pota-to. Oh-oh.
Let's NOT call the whole thing off
A database wrapper library such as ADODB comes in handy when you need to ensure portability. It provides
you with a common API to communicate with any supported database so you don't have to call things off.
ADODB stands for Active Data Objects DataBase (sorry computer guys are sometimes
not very original). ADODB currently supports MySQL, PostgreSQL, Oracle, Interbase,
Microsoft SQL Server, Access, FoxPro, Sybase, ODBC and ADO. You can download
ADODB from
Object that performs the connection to the database, executes SQL statements
and has a set of utility functions for standardising the format of SQL statements
for issues such as concatenation and date formats.
Other Useful Functions
$recordset->Move($pos) scrolls to that particular row. ADODB supports forward
scrolling for all databases. Some databases will not support backwards scrolling.
This is normally not a problem as you can always cache records to simulate backwards
scrolling.
$recordset->RecordCount() returns the number of records accessed by the
SQL statement. Some databases will return -1 because it is not supported.
$recordset->GetArray() returns the result as an array.
rs2html($recordset) is a function that is generates a HTML table based on the
$recordset passed to it. An example with the relevant lines in bold:
include('adodb.inc.php');
include('tohtml.inc.php'); /* includes the rs2html function */
$conn = ADONewConnection('mysql');
$conn->PConnect('localhost','userid','password','database');
$rs = $conn->Execute('select * from table');
rs2html($rs); /* recordset to html table */
There are many other helper functions that are listed in the documentation available at .
Advanced Material
Inserts and Updates
Let's say you want to insert the following data into a database.
ID = 3
TheDate=mktime(0,0,0,8,31,2001) /* 31st August 2001 */
Note= sugar why don't we call it off
When you move to another database, your insert might no longer work.
The first problem is that each database has a different default date format.
MySQL expects YYYY-MM-DD format, while other databases have different defaults.
ADODB has a function called DBDate() that addresses this issue by converting
converting the date to the correct format.
The next problem is that the don't in the Note needs to be quoted. In
MySQL, we use don\'t but in some other databases (Sybase, Access, Microsoft
SQL Server) we use don''t. The qstr() function addresses this issue.
So how do we use the functions? Like this:
$sql = "INSERT INTO table (id, thedate,note) values ("
. $ID . ','
. $db->DBDate($TheDate) .','
. $db->qstr($Note).")";
$db->Execute($sql);
ADODB also supports $connection->Affected_Rows() (returns the
number of rows affected by last update or delete) and $recordset->Insert_ID()
(returns last autoincrement number generated by an insert statement). Be forewarned
that not all databases support the two functions.
MetaTypes
You can find out more information about each of the fields (I use the words
fields and columns interchangebly) you are selecting by calling the recordset
method FetchField($fieldoffset). This will return an object with
3 properties: name, type and max_length.
For example:
$recordset = $conn->Execute("select adate from table");
$f0 = $recordset->FetchField(0);
Then $f0->name will hold 'adata', $f0->type
will be set to 'date'. If the max_length is unknown, it will be set to
-1.
One problem with handling different databases is that each database often calls
the same type by a different name. For example a timestamp type is called
datetime in one database and time in another. So ADODB has a special
MetaType($type, $max_length) function that standardises the types
to the following:
C: character and varchar types
X: text or long character (eg. more than 255 bytes wide).
B: blob or binary image
D: date
T: timestamp
L: logical (boolean)
I: integer
N: numeric (float, double, money)
In the above date example,
$recordset = $conn->Execute("select adate from table");
$f0 = $recordset->FetchField(0);
$type = $recordset->MetaType($f0->type, $f0->max_length);
print $type; /* should print 'D' */
Select Limit and Top Support
ADODB has a function called $connection->SelectLimit($sql,$nrows,$offset) that allows
you to retrieve a subset of the recordset. This will take advantage of native
SELECT TOP on Microsoft products and SELECT ... LIMIT with PostgreSQL and MySQL, and
emulated if the database does not support it.
Caching Support
ADODB allows you to cache recordsets in your file system, and only requery the database
server after a certain timeout period with $connection->CacheExecute($secs2cache,$sql) and
$connection->CacheSelectLimit($secs2cache,$sql,$nrows,$offset).
PHP4 Session Handler Support
ADODB also supports PHP4 session handlers. You can store your session variables
in a database for true scalability using ADODB. For further information, visit
Commercial Use Encouraged
If you plan to write commercial PHP applications that you want to resell, you should consider ADODB. It has been released using the lesser GPL, which means you can legally include it in commercial applications, while keeping your code proprietary. Commercial use of ADODB is strongly encouraged! We are using it internally for this reason.
