I have the following query so far:
$shopQuery = $qb->select('DISTINCT u')
->from("BlahUserBundle:User", 'u')
->innerJoin('u.followers', 'followers')
->andWhere('followers.id != :userId')
->setParameter('userId', $user->getId())
->orWhere('') //or where those user who doesn't have a follower yet
//->setMaxResults(5)
;
I am trying to find a way to query all users who doesn't have a follower and whose follower is not my self (in this case my self is $user->getId()). How do I do so?
Try this
$shopQuery = $qb->from("BlahUserBundle:User", 'u')
->leftJoin(
'u.followers',
'followers',
'on',
'followers.id != :userId'
)
->where('followers.id IS NULL')
->setParameter('userId', $user->getId());
$shopQuery->getQuery()->getResults();

This is my function where I'm trying to show the User history. For this I need to display the user's current credits along with his credit history.
This is what I am trying to do:
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb->select(array('a','u'))
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin('User\Entity\User', 'u', \Doctrine\ORM\Query\Expr\Join::WITH, 'a.user = u.id')
->where("a.user = $users ")
->orderBy('a.created_at', 'DESC');
$query = $qb->getQuery();
$results = $query->getResult();
return $results;
}
However, I get this error :
[Syntax Error] line 0, col 98: Error: Expected Doctrine\ORM\Query\Lexer::T_WITH, got 'ON'
Edit: I replaced 'ON' with 'WITH' in the join clause and now what I see is only 1 value from the joined column.
If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin('a.user', 'u')
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.
If no association is available, then the query looks like following
public function getHistory($users) {
$qb = $this->entityManager->createQueryBuilder();
$qb
->select('a', 'u')
->from('Credit\Entity\UserCreditHistory', 'a')
->leftJoin(
'User\Entity\User',
'u',
\Doctrine\ORM\Query\Expr\Join::WITH,
'a.user = u.id'
)
->where('u = :user')
->setParameter('user', $users)
->orderBy('a.created_at', 'DESC');
return $qb->getQuery()->getResult();
}
This will produce a resultset that looks like following:
array(
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
array(
0 => UserCreditHistory instance,
1 => Userinstance,
),
// ...
)
i'm facing a strange problem: here is the deal.
When i am doing this:
$query = $this->createQueryBuilder('s')
->select('s')
->leftJoin('s.Cluster', 'u')
->where('u.id = 15')
->orWhere('u.id=37')
->getQuery()
->getResult();
var_dump(count($query));
the output is 2
but if i do :
$query = $this->createQueryBuilder('s')
->select('s')
->leftJoin('s.Cluster', 'u')
->where('u.id = 15')
->orWhere('u.id=37');
$query
->getQuery()
->getResult();
var_dump(count($query));
the output is 1.. can someone explain? i don't understand where it could come from
I try to convert this query to the querybuilder:
SELECT *, landingpages_content.id as cid FROM `landingpages_content` LEFT JOIN content ON landingpages_content.content_id = content.id WHERE content.enabled = 1 AND landingpages_content.landingpage_id = ? ORDER BY landingpages_content.`order`
This is my QueryBuilder code:
$queryBuilder
->select('*, landingpages_content.id as cid')
->from('landingpages_content', 'landingpages_content')
->leftJoin('landingpages_content.content_id', 'content.id', null)
->where('content.enabled = 1')
->andWhere('landingpages_content.landingpage_id = :id')
->setParameter('id', $id)
->orderBy('landingpages_content.`order`', 'ASC');
It returns
InvalidArgumentException: The query builder cannot have joins.
You are using leftJoin method wrong. Try something like this:
$queryBuilder
->select('*, landingpages_content.id as cid')
->from('landingpages_content', 'landingpages_content')
->leftJoin('landingpages_content.content', 'content', 'ON', 'landingpages_content.content_id = content.id')
->where('content.enabled = 1')
->andWhere('landingpages_content.landingpage_id = :id')
->setParameter('id', $id)
->orderBy('landingpages_content.order', 'ASC');

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.
Actually if you are using the Symfony2 repository class you could also do the following:
$in = $this->getEntityManager()->getRepository('Custom:MembreService')
->createQueryBuilder('ms')
->select('identity(ms.m)')
->where(ms.id != ?1);
$q = $this->createQueryBuilder('m')
->where($q->expr()->notIn('m.id', $in->getDQL()))
->setParameter(1, $service);
return $q->getQuery()->execute();
You can use (NOT) MEMBER OF:
<?php
$query = $em->createQuery('SELECT m.id FROM Custom\Entity\Membre WHERE :service NOT MEMBER OF m.services');
$query->setParameter('service', $service);
$ids = $query->getResult();
See the documentation for more examples.
