Count Rows in Doctrine QueryBuilder
Acyra’s Question:
I’m using Doctrine’s QueryBuilder to build a query, and I want to get the total count of results from the query.
$repository = $em->getRepository('FooBundle:Foo');
$qb = $repository->createQueryBuilder('n')
->where('n.bar = :bar')
->setParameter('bar', $bar);
$query = $qb->getQuery();
//this doesn't work
$totalrows = $query->getResult()->count();
I just want to run a count on this query to get the total rows, but not return the actual results. (After this count query, I’m going to further modify the query with maxResults for pagination.)
Something like:
$qb = $entityManager->createQueryBuilder();
$qb->select('count(account.id)');
$qb->from('ZaysoCoreBundle:Account','account');
$count = $qb->getQuery()->getSingleScalarResult();
For people who are using only Doctrine DBAL and not the Doctrine ORM, they will not be able to access the getQuery() method because it doesn’t exists. They need to do something like the following.
$qb = new QueryBuilder($conn);
$count = $qb->select("count(id)")->from($tableName)->execute()->fetchColumn(0);
