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

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 have a select with SQL which is working perfectly, but I cannot translate this query to DQL with createQueryBuilder().
Here's my query:
SELECT distinct c.name_id
FROM cultures AS c
LEFT JOIN ilots AS i ON i.exploitation_id = 1
My current code:
return $this->createQueryBuilder('c')
->leftJoin(Ilots::class, 'i', 'ON', 'i.exploitation = 1')
->distinct()
->getQuery()
->getResult();
And the error:
[Syntax Error] line 0, col 74: Error: Expected end of string, got 'ON'
In DQL ON doesn't exist, you have to use WITH instead.
return $this->createQueryBuilder('c')
->leftJoin(Ilots::class, 'i', 'WITH', 'i.exploitation = 1')
->distinct()
->getQuery()
->getResult();

If there is relationship between the Entity:
$qb = $this->entityManager->createQueryBuilder('c')
->select('c')
->distinct()
->from('cultures', 'c')
->leftJoin('c.ilots', 'i')
->where('i.exploitation = 1')
;
return $qb->getQuery()->getResult();
I have few tables, and get resuts for it.
$qb = $this->createQueryBuilder('a');
$qb->select("a, c, ac")
->leftJoin('a.categories', 'c')
->leftJoin('a.comments', 'ac')
->where('c.slug = :category')
->setParameter('category', $category)
->orderBy('a.name', 'ASC');
return $qb->getQuery();
I want this result, order by comments (ac) count. How can I solve this?
$qb = $this->createQueryBuilder('a');
$qb->select("a, c, ac, count(a.comments) AS HIDDEN nbcomments")
->leftJoin('a.categories', 'c')
->leftJoin('a.comments', 'ac')
->where('c.slug = :category')
->setParameter('category', $category)
->orderBy('a.name', 'ASC')
->addOrderBy('nbcomments', 'ASC');
return $qb->getQuery();
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.
