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.
This bundle requires the following:
- pdo_dblib
- FreeTDS
DBLib requires FreeTDS. We can't go into detail about configuring FreeTDS, but the connection configured should look something like following:
[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:
# Doctrine Configuration
doctrine:
dbal:
driver_class: PDODblibBundle\Doctrine\DBAL\Driver\PDODblib\Driver
host: mssql_freetds
And in your autoload.php
register the new bundle:
$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:
-
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
You can find a patch for some of the short-comings of pdo_dblib on SVN.

See: Revision 300647 - lastInsertId Revision 300628 - transaction support
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
:
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:
- Map any non-compatible column types to string
- Hack the Doctrine core to skip any tables without primary keys
