I'd like to select members who are not in specific service. I have 3 tables :
membre
service
membre_service
(relation between membre
and service
)I'm using doctrine 2 and in SQL my query is :
SELECT m.* FROM membre m WHERE m.`id` NOT IN (
SELECT ms.membre_id FROM membre_service ms WHERE ms.service_id != 29
)
In Doctrine, I do :
$qb = $this->_em->createQueryBuilder();
$qb2 = $qb;
$qb2->select('m.id')
->from('Custom\Entity\MembreService', 'ms')
->leftJoin('ms.membre', 'm')
->where('ms.id != ?1')
->setParameter(1, $service);
$qb = $this->_em->createQueryBuilder();
$qb->select('m')
->from('Custom\Entity\Membre', 'm')
->where($qb->expr()->notIn('m.id', $qb2->getDQL())
);
$query = $qb->getQuery();
//$query->useResultCache(true, 1200, __FUNCTION__);
return $query->getResult();
I got the following error :
Semantical Error] line 0, col 123 near 'm WHERE ms.id': Error: 'm' is already defined.
The same alias cannot be defined 2 times in the same query
$qb = $this->_em->createQueryBuilder();
$qb2 = $qb;
$qb2->select('m.id')
->from('Custom\Entity\MembreService', 'ms')
->leftJoin('ms.membre', 'm')
->where('ms.id != ?1');
$qb = $this->_em->createQueryBuilder();
$qb->select('mm')
->from('Custom\Entity\Membre', 'mm')
->where($qb->expr()->notIn('mm.id', $qb2->getDQL())
);
$qb->setParameter(1, $service);
$query = $qb->getQuery();
return $query->getResult();
Ideally you should use many-to-many relation for your entity, in this case your query is going to be much simpler.
