Better to use DQL for getting Column Count or Get Collection Then Count?

Question

I am quite sure that DQL will be the way to go, but I am wondering if Doctrine, i am using Doctrine 2, has someway to return the row count. I won't be using the rows itself, I just want the count.

Answer 1

I'm new to Doctrine2 but it looks like you can simply do this:

$query = $em->createQuery('SELECT COUNT(u.id) FROM Entities\User u');
$count = $query->getSingleScalarResult();
