Doctrine 2 WHERE IN clause using a collection of entities

Question

I\'m attempting to build a query in Doctrine 2 that finds all Vacancy entities which are related to any of the given VacancyWorkingHours entities.<

Answer 1

Try to set IDs as parameter

$ids = array();
foreach($workingHours as $w) {
    $ids[] = $w->getId();
}

Then

$q = $this->createQueryBuilder('v')
    ->select('v')
    ->andWhere('v.workingHours IN (:workingHours)')
    ->setParameter('workingHours', $ids);
;

Answer 2

I think the DQL will work better for that.

$em = $this->getDoctrine()->getEntityManager();
$query = $em->createQuery(
    'SELECT v
    FROM YourAppYourBundle:YourEntity v // exemple AcmeexampleBundle:YourEntity
    WHERE v.workingHours IN :workingHours'
)->setParameter('workingHours', $workingHours->toArray());

$vacancies = $query->getResult();

Answer 3

I suggest using DQL in this way:

$qb = $this->createQueryBuilder('v')
    ->andWhere($qb->expr()->in('v.workingHours', $ids));
;

And let Doctrine handle the expression & quotation work for you.

Answer 4

A pull request I made about this has been merged into Doctrine ORM 2.5, so you can simply do this now:

$q = $this->createQueryBuilder('v')
    ->select('v')
    ->andWhere('v.workingHours IN (:workingHours)')
    ->setParameter('workingHours', $workingHours);
;

The latest version of Doctrine now allows collection parameters and will automatically make use of the primary key of each of the collection entries.
