Doctrine: Counting an entity's items with a condition

Question

How can I count an entity\'s items with a condition in Doctrine? For example, I realize that I can use:

$usersCount = $dm->getRepository(\'User\')->count()

Well, you could use the QueryBuilder to setup a COUNT query:

Presuming that $dm is your entity manager.

$qb = $dm->createQueryBuilder();

$qb->select($qb->expr()->count('u'))
   ->from('User', 'u')
   ->where('u.type = ?1')
   ->setParameter(1, 'employee');

$query = $qb->getQuery();

$usersCount = $query->getSingleScalarResult();

Or you could just write it in DQL:

$query = $dm->createQuery("SELECT COUNT(u) FROM User u WHERE u.type = ?1");
$query->setParameter(1, 'employee');

$usersCount = $query->getSingleScalarResult();

The counts might need to be on the id field, rather than the object, can't recall. If so just change the COUNT(u) or ->count('u') to COUNT(u.id) or ->count('u.id') or whatever your primary key field is called.
