Symfony2 & Doctrine: Create custom SQL-Query

Question

How can I create a custom SQL query in Symfony2 using Doctrine? Or without Doctrine, I don't care.

Doesn't work like this:

    $em = $this->getDoctrine()->getEntityManager();     $em->createQuery($sql);     $em->execute(); 

Thanks.

You can get the Connection object directly from the Entity Manager, and run SQL queries directly through that:

$em = $this->getDoctrine()->getManager(); // ...or getEntityManager() prior to Symfony 2.1 $connection = $em->getConnection(); $statement = $connection->prepare("SELECT something FROM somethingelse WHERE id = :id"); $statement->bindValue('id', 123); $statement->execute(); $results = $statement->fetchAll(); 

However, I'd advise against this unless it's really necessary... Doctrine's DQL can handle almost any query you might need.
