PDO DBlib Driver for Symfony
This PDO DBLib bundle adds support for Microsoft SQL Server Doctrine 2. Take it with a grain of salt: Many of the Doctrine unit tests fail when using this driver. PHP's PDO_DBLIB driver does not support many of the features within doctrine. There is a patch in the PHP repo to add transaction and lastInsertId support, but this package has some minor work arounds., (*1)
This bundle requires the following: * pdo_dblib * FreeTDS, (*2)
DBLib requires FreeTDS. We can't go into detail about configuring FreeTDS, but the connection configured should look something like following:, (*3)
[mssql_freetds] host = 192.168.1.1 port = 1433 tds version = 8.0 client charset = UTF-8 text size = 20971520
In your Symfony2 project, modify your config.yml
as follows to use the DBlib bundle and the server setup under FreeTDS:, (*4)
# Doctrine Configuration doctrine: dbal: driver_class: PDODblibBundle\Doctrine\DBAL\Driver\PDODblib\Driver host: mssql_freetds
And in your autoload.php
register the new bundle:, (*5)
$loader->registerNamespaces(array( 'PDODblib' => __DIR__ . '/../vendor/bundles', ));
Getting everything together wasn't easy. You need to complete the following steps, checking each installation is successful by connecting with the appropriate tools:, (*6)
Install FreeTDS and configure a server connection, (*7)
Install the PHP DBLib extension -- verify with PHP script containing, (*8)
Install and configure the PDODblibBundle, (*9)
You can find a patch for some of the short-comings of pdo_dblib on SVN., (*10)
http://svn.php.net/viewvc/php/php-src/trunk/ext/pdo_dblib/dblib_driver.c?view=log, (*11)
See: Revision 300647 - lastInsertId Revision 300628 - transaction support, (*12)
Doctrine2's test suite does not allow you to add database drivers on the fly. If you want to test this package, modify Doctrine/DBAL/Driver/DriverManager::$_driverMap
:, (*13)
final class DriverManager { private static $_driverMap = array( /* ... snip ... */ 'pdo_dblib' => 'Doctrine\DBAL\Driver\PDODblib\Driver', ); }
It's possible, but not easy. Here's what I did:, (*14)
