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 was wondering if I could possibly order multiple entities by their date of creation with the query builder in Symfony.
This is my query:
public function findContributions(Association $association)
{
return $this->createQueryBuilder('a')
->select('d, ms, m')
->addSelect('greatest(ms.createdAt, d.createdAt) AS date')
->from(Membership::class, 'ms')
->from(Donation::class, 'd')
->leftJoin('ms.member', 'm')
->Where('m.association = a.id')
->andWhere('d.association = a.id')
->orderBy('date', 'DESC')
->getQuery()
->getResult();
}
My results so far :
I would like to order by the column created_at located in both of my entities (membership and donation).
Is there any way I can achieve this?
Thank you !
I think you can use
public function addOrderBy($sort, $order = null); // Default $order = 'ASC'
Doing something like
return $this->createQueryBuilder('a')
->select('d, ms, m')
->addSelect('greatest(ms.createdAt, d.createdAt) AS date')
->from(Membership::class, 'ms')
->from(Donation::class, 'd')
->leftJoin('ms.member', 'm')
->Where('m.association = a.id')
->andWhere('d.association = a.id')
->orderBy('m.date', 'DESC')
->addOrderBy('d.date', 'DESC')
->getQuery()
->getResult();

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');
