ADOdb old Changelog - v4.x

See the Current Changelog. Older changelogs: v3.x, v2.x.

4.990 - 11 Jul 2008

Added support for multiple recordsets in mysqli Geisel Sierote . See http://phplens.com/lens/lensforum/msgs.php?id=15917
Malcolm Cook added new Reload() function to Active Record. See http://phplens.com/lens/lensforum/msgs.php?id=17474
Thanks Zoltan Monori [monzol#fotoprizma.hu] for bug fixes in iterator, SelectLimit, GetRandRow, etc.
Under heavy loads, the performance monitor for oci8 disables Ixora views.
Fixed sybase driver SQLDate to use str_replace(). Also for adodb5, changed sybase driver UnixDate and UnixTimeStamp calls to static.
Changed oci8 lob handler to use & reference $this->_refLOBs[$numlob]['VAR'] = &$var.
We now strtolower the get_class() function in PEAR::isError() for php5 compat.
CacheExecute did not retrieve cache recordsets properly for 5.04 (worked in 4.98). Fixed.
New ADODB_Cache_File class for file caching defined in adodb.inc.php.
Farsi language file contribution by Peyman Hooshmandi Raad (phooshmand#gmail.com)

New API for creating your custom caching class which is stored in $ADODB_CACHE:

include "/path/to/adodb.inc.php";
$ADODB_CACHE_CLASS = 'MyCacheClass';
    
class MyCacheClass extends ADODB_Cache_File
{
    function writecache($filename, $contents,$debug=false){...}
    function &readcache($filename, &$err, $secs2cache, $rsClass){ ...}
        :
}
    
$DB = NewADOConnection($driver);
$DB->Connect(...);  ## MyCacheClass created here and stored in $ADODB_CACHE global variable.
    
$data = $rs->CacheGetOne($sql); ## MyCacheClass is used here for caching...

Memcache supports multiple pooled hosts now. Only if none of the pooled servers can be contacted will a connect error be generated. Usage example below:

$db = NewADOConnection($driver);
$db->memCache = true; /// should we use memCache instead of caching in files
$db->memCacheHost = array($ip1, $ip2, $ip3); /// $db->memCacheHost = $ip1; still works
$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);

4.98 - 13 Feb 2008

Fixed adodb_mktime problem which causes a performance bottleneck in $hrs.
Added mysqli support to adodb_getcount().
Removed MYSQLI_TYPE_CHAR from MetaType().

4.97 - 22 Jan 2008

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 - 24 Sept 2007

ADOdb perf for oci8 now has non-table-locking code when clearing the sql. Slower but better transparency. Added in 4.96a and 5.02a.
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 $nrows check.
Active record optimizations. Added support for assoc arrays in Set().
Now GetOne returns null if EOF (no records found), and false if error occurs. Use ErrorMsg()/ErrorNo() to get the error.
Also CacheGetRow and CacheGetCol will return false if error occurs, or empty array() if EOF, just like GetRow and GetCol.
Datadict now allows changing of types which are not resizable, eg. VARCHAR to TEXT in ChangeTableSQL. -- Mateo Tibaquirá
Added BIT data type support to adodb-ado.inc.php and adodb-ado5.inc.php.
Ldap driver did not return actual ldap error messages. Fixed.
Implemented GetRandRow($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 no longer deletes all files directories. Only *.cache files deleted.
DB2 timestamp format changed to var $fmtTimeStamp = 'Y-m-d-H:i:s';
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.

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
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().
Transpose now adds the field names as the first column after transposition.
Added === check in ADODB_SetDatabaseAdapter for $db, adodb-active-record.inc.php. Thx Christian Affolter.
Added ErrorNo() to adodb-active-record.inc.php. Thx ante#novisplet.com.

4.93 - 10 Oct 2006

Added support for multiple database connections in performance monitoring code (adodb-perf.inc.php). Now all sql in multiple database connections can be saved into one database ($ADODB_LOG_CONN).
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 INT in oci8 to return correct precision in $fld->max_length, MetaColumns(). Thx Eloy Lafuente Plaza.

Fixed postgres connection bug: http://phplens.com/lens/lensforum/msgs.php?id=11057.
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);

4.91 - 2 Aug 2006

Major session code rewrite... See session docs.
PDO bindinputarray() was not set properly for MySQL (changed from true to false).

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.

4.90 - 8 June 2006

Changed adodb_countrec() in adodb-lib.inc.php to allow LIMIT to be used as a speedup to reduce no of records counted.

Rolled back MetaType() changes for mysqli done in prev version.

Datadict change by chris, cblin#tennaxia.com data mappings from:

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.
Added ifnull handling for postgresql (using coalesce).

- 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.

4.53 - 28 Sept 2004

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.
Empty() used in getupdatesql without strlen() check. Fixed.
Added unsigned detection to mysql and mysqli drivers. Thx to dan cech.
Added hungarian language file. Thx to Halászvári Gábor.
Improved fieldname-type formatting of datadict SQL generated (adding $widespacing parameter to _GenField).
Datadict oci8 DROP CONSTRAINTS misspelt. Fixed. Thx Mark Newnham.
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" RalfBecker#digitalROCK.de contributed new sapdb data-dictionary driver and a large patch that implements field and table renaming for oracle, mssql, postgresql, mysql and sapdb. See the new RenameTableSQL() and RenameColumnSQL() functions.
We now check ExecuteCursor to see if PrepareSP was initially called.
Changed oci8 datadict to use MODIFY for $dd->alterCol. Thx Mark Newnham.

4.52 - 10 Aug 2004

Bug found in Replace() when performance logging enabled, introduced in ADOdb 4.50. Fixed.

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

4.51 - 29 July 2004

Added adodb-xmlschema 1.0.2. Thx dan and richard.
Added new adorecordsetext* classes. If ADOdb extension installed for mysql, mysqlt and oci8 (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 support for clob's for mssql, UpdateBlob(). Thx to gfran#directa.com.br
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.

Optimizations to MoveNext() for mysql and oci8. Misc speedups to Get* functions.

4.50 - 6 July 2004

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.

4.23 - 16 June 2004

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;

$this->_transactionID = ibase_trans($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>";</pre>

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().

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.

4.21 - 20 Mar 2004

We no longer in SelectLimit for VFP driver add SELECT TOP X unless an ORDER BY exists.
Pim Koeman contributed dutch language file adodb-nl.inc.php.
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.

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.

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.
