LswDoctrinePdoDblib

Doctrine 2 does support any method of connecting to SQL Server on a Linux box. Here's a simple driver that supports PDO DBlib. Many tests fail, but most are related to shortcomings of the PDODBlib driver. 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)

FreeTDS configuration

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 = 172.30.252.25
    port = 1433
    tds version = 8.0
    client charset = UTF-8
    text size = 20971520

Setting up bundle in Symfony

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:   Lsw\DoctrinePdoDblib\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',
));

Putting everything together

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
- Verify with ./tsql -S mssql_freetds -U yourusername -P yourpassword
Install the PHP DBLib extension -- verify with PHP script containing
- Verify $pdo = new PDO('dblib:host=mssql_freetds;dbname=yourdb', 'yourusername', 'yourpassword');
Install and configure the PDODblibBundle
- Verify Some kind of SQL against your database

FYI - PHP pdo_dblib patch

You can find a patch for some of the short-comings of pdo_dblib on SVN., _(*7)

http://svn.php.net/viewvc/php/php-src/trunk/ext/pdo_dblib/dblib_driver.c?view=log, _(*8)

See: Revision 300647 - lastInsertId Revision 300628 - transaction support, _(*9)

FYI - Doctrine Test Suite

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 as follows:, _(*10)

final class DriverManager
{
    private static $_driverMap = array(
        /* ... snip ... */
        'pdo_dblib' => 'Doctrine\DBAL\Driver\PDODblib\Driver',
    );
}
