## 5.19 - 2014-04-23

**NOTE:**
This release suffers from a [known issue with Associative Fetch Mode](https://github.com/ADOdb/ADOdb/issues/20)
(i.e. when $ADODB_FETCH_MODE is set to ADODB_FETCH_ASSOC).
It causes recordsets to return empty strings (no data) when using some database drivers.
The problem has been reported on MSSQL, Interbase and Foxpro, but possibly affects
other database types as well; all drivers derived from the above are also impacted.

- adodb: GetRowAssoc will return null as required. See PHPLens Issue No: 19289
- adodb: Fix GetRowAssoc bug introduced in 5.17, causing function to return data from previous fetch for NULL fields. See PHPLens Issue No: 17539
- adodb: GetAssoc will return a zero-based array when 2nd column is null. See https://sourceforge.net/p/adodb/bugs/130/
- adodb: Execute no longer ignores single parameters evaluating to false. See https://sourceforge.net/p/adodb/patches/32/
- adodb: Fix LIMIT 1 clause in subquery gets stripped off. See PHPLens Issue No: 17813
- adodb-lib: Fix columns quoting bug. See https://sourceforge.net/p/adodb/bugs/127/
- Added new ADODB_ASSOC_CASE_* constants. Thx to Damien Regad.
- sessions: changed lob handling to detect all variations of oci8 driver.
- ads: clear fields before fetching. See PHPLens Issue No: 17539
- mssqlnative: fixed many FetchField compat issues. See PHPLens Issue No: 18464. Also date format changed to remove timezone.
- mssqlnative: Numerous fixes and improvements by Mark Newnham
    - Driver supports SQL Server 2005, 2008 and 2012
    - Bigint data types mapped to I8 instead of I
    - Reintroduced MetaColumns function
    - On SQL Server 2012, makes use of new CREATE SEQUENCE statement
    - FetchField caches metadata at initialization to improve performance
    - etc.
- mssqlnative: Fix Insert ID on prepared statement, thanks to Mike Parks. See PHPLens Issue No: 19079
- mssql: timestamp format changed to `Y-m-d\TH:i:s` (ISO 8601) to make them independent from DATEFORMAT setting, as recommended on
  [Microsoft TechNet](http://technet.microsoft.com/en-us/library/ms180878%28v=sql.105%29.aspx#StringLiteralDateandTimeFormats).
- mysql/mysqli: Fix ability for MetaTables to filter by table name, broken since 5.15. See PHPLens Issue No: 19359
- odbc: Fixed MetaTables and MetaPrimaryKeys definitions in odbc driver to match adoconnection class.

  [#9](https://github.com/ADOdb/ADOdb/issues/9)
- sybase: Fix null values returned with ASSOC fetch mode
  [#10](https://github.com/ADOdb/ADOdb/issues/10)
- Added Composer support
  [#7](https://github.com/ADOdb/ADOdb/issues/7)

## 5.18 - 2012-09-03

- mssqlnative: Prepare() did not work previously. Now calling Prepare() will work but the sql is not actually compiled. Unfortunately bind params are passed to sqlsrv_prepare and not to sqlsrv_execute. make Prepare() and empty function, and we still execute the unprepared stmt.
- mysql: FetchField(-1), turns it is is not possible to retrieve the max_length. Set to -1.
- mysql-perf: Fixed "SHOW INNODB STATUS". Change to "SHOW ENGINE INNODB STATUS"

## 5.17 - 2012-05-18

- oci8: Changed to use newer oci API to support PHP 5.4.
- adodb.inc.php: Changed GetRowAssoc to more generic code that will work in all scenarios.

- mysqli: added support for persistent connections 'p:'.
- mssqlnative: ADODB_FETCH_BOTH did not work properly. Fixed.
- mssqlnative: return values for stored procedures where not returned! Fixed. See PHPLens Issue No: 18919

## 5.11 - 2010-05-05

- mysql: Fixed GetOne() to return null if no records returned.
- oci8 perf: added stats on sga, rman, memory usage, and flash in performance tab.
- odbtp: Now you can define password in $password field of Connect()/PConnect(), and it will add it to DSN.
- Datadict: altering columns did not consider the scale of the column. Now it does.
- mssql: Fixed problem with ADODB_CASE_ASSOC causing multiple versions of column name appearing in recordset fields.
- oci8: Added missing & to refLob.

- oci8: Now you can get column info of a table in a different schema, e.g. MetaColumns("schema.table") is supported.
- odbc_mssql: Fixed missing $metaDatabasesSQL.
- xmlschema: Changed declaration of create() to create($xmls) to fix compat problems. Also changed constructor adoSchema() to pass in variable instead of variable reference.
- ado5: Fixed ado5 exceptions to only display errors when $this->debug=true;
- Added DSN support to sessions2.inc.php.
- adodb-lib.inc.php. Fixed issue with _adodb_getcount() not using $secs2cache parameter.
- adodb active record. Fixed caching bug. See PHPLens Issue No: 18288.
- db2: fixed ServerInfo().
- adodb_date: Added support for format 'e' for TZ as in adodb_date('e')
- Active Record: If you have a field which is a string field (with numbers in) and you add preceding 0's to it the adodb library does not pick up the fact that the field has changed because of the way php's == works (dodgily). The end result is that it never gets updated into the database - fix by Matthew Forrester (MediaEquals). [matthew.forrester#mediaequals.com]
- Fixes RowLock() and MetaIndexes() inconsistencies. See PHPLens Issue No: 18236
- Active record support for postgrseql boolean. See PHPLens Issue No: 18246

- MSSQL: fixes for 5.2 compat. PHPLens Issue No: 18325
- Changed Version() to return a string instead of a float so it correctly returns 5.10 instead of 5.1.

## 5.10 - 2009-11-10

- New db2oci driver for db2 9.7 when using PL/SQL mode. Allows oracle style :0, :1, :2 bind parameters which are remapped to ? ? ?.
- adodb-db2.inc.php: fixed bugs in MetaTables. SYS owner field not checked properly. Also in $conn->Connect($dsn, null, null, $schema) and PConnect($dsn, null, null, $schema), we do a SET SCHEMA=$schema if successful connection.
- adodb-mysqli.inc.php: Now $rs->Close() closes all pending next resultsets. Thx Clifton mesmackgod#gmail.com
- Moved _CreateCache() from PConnect()/Connect() to CacheExecute(). Suggested by Dumka.
- Many bug fixes to adodb-pdo_sqlite.inc.php and new datadict-sqlite.inc.php. Thx Andrei B. [andreutz#mymail.ro]

- Fixed RowLock() parameters to comply with PHP5 strict mode in multiple drivers.

## 5.09 - 2009-06-25

- Active Record: You can force column names to be quoted in INSERT and UPDATE statements, typically because you are using reserved words as column names by setting ADODB_Active_Record::$_quoteNames = true;
- Added memcache and cachesecs to DSN. e.g.

    ``` php
    # we have a memcache servers mem1,mem2 on port 8888, compression=off and cachesecs=120
    $dsn = 'mysql://user:pwd@localhost/mydb?memcache=mem1,mem2:8888:0&cachesecs=120';
    ```

- Datadict: In order to support TIMESTAMP with subsecond accuracy, added to datadict the new TS type. Supported by mssql, postgresql and oci8 (oracle). Also changed oci8 $conn->sysTimeStamp to use 'SYSTIMESTAMP' instead of 'SYSDATE'. Should be backwards compat.
- Added support for PHP 5.1+ DateTime objects in DBDate and DBTimeStamp. This means that dates and timestamps will be managed by DateTime objects if you are running PHP 5.1+.
- Added new property to postgres64 driver to support returning I if type is unique int called $db->uniqueIisR, defaulting to true. See PHPLens Issue No: 17963
- Added support for bindarray in adodb_GetActiveRecordsClass with SelectLimit in adodb-active-record.inc.php.

- You can now change the return value of GetOne if no records are found using the global variable $ADODB_GETONE_EOF. The default is null. To change it back to the pre-4.99/5.00 behaviour of false, set $ADODB_GETONE_EOF = false;
- In Postgresql 8.2/8.3 MetaForeignkeys did not work. Fixed William Kolodny William.Kolodny#gt-t.net

## 5.05 - 2008-07-11

Released together with [v4.990](changelog_v4.x.md#4990---11-jul-2008)

- Added support for multiple recordsets in mysqli , thanks to Geisel Sierote geisel#4up.com.br. See PHPLens Issue No: 15917
- Malcolm Cook added new Reload() function to Active Record. See PHPLens Issue No: 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:

    ``` php
    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:

    ``` php
    $db = NewADOConnection($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);
    ```

## 5.04 - 2008-02-13

Released together with [v4.98](changelog_v4.x.md#498---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().

## 5.03 - 2008-01-22

Released together with [v4.97](changelog_v4.x.md#497---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. PHPLens Issue No: 17200
- Removed $arg3 from mysqli SelectLimit. See PHPLens Issue No: 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.

## 5.02 - 2007-09-24

Released together with [v4.96](changelog_v4.x.md#496---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 $nrows check.
- Active record optimizations. Added support for assoc arrays in Set().
- Now GetOne returns null if EOF (no records found), and false if error occurs. Use ErrorMsg()/ErrorNo() to get the error.
- Also CacheGetRow and CacheGetCol will return false if error occurs, or empty array() if EOF, just like GetRow and GetCol.
- Datadict now allows changing of types which are not resizable, eg. VARCHAR to TEXT in ChangeTableSQL. -- Mateo TibaquirÃ¡
- Added BIT data type support to adodb-ado.inc.php and adodb-ado5.inc.php.
- Ldap driver did not return actual ldap error messages. Fixed.
- Implemented GetRandRow($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.
- Changed parser for pgsql error messages in adodb-error.inc.php to case-insensitive regex.

## 5.01 - 2007-05-17

Released together with [v4.95](changelog_v4.x.md#495---17-may-2007)

- 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.
- 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.
- Adodb5 version,more error checking code now will use exceptions if available.
