此代码不起作用。有谁能够帮我?代码是:
class ResultRepository extends EntityRepository
{
public function findAllByUserResultVote($id_vote)
{
$query = $this->createQueryBuilder('r')
//associating tables...
->leftJoin('r.user' , 'u')
->leftJoin('r.answer' , 'a')
->leftJoin('r.vote' , 'v')
//Where idVote (Table result) == id (Table vote)
->where('r.idVote = :idVote')
->setParameter('idVote', $id_vote)
->getQuery();
return $query->getResult();
}
}
我有一个实体用户,答案,投票,结果。
我有4张桌子:
用户:id(主要),名称,...
投票:id(主要),问题,...
答案:id(主要),idVote,回答...
结果:id(主要),idUser(id表用户),idVote(id表投票),idAnswer(id表回答),...

谢谢你的答案,但那不是我的所作所为
结果也是一张表。这只包含id,我需要返回例如:
而不是: 1,6,5,3
这个: 1,u.name,v.question,a.answer
答案 0 :(得分:0)
public function findAllByUserResultVote($idVote)
{
$queryBuilder = $this->createQueryBuilder('r')
// From your question, it looks like you only want ids
->select('r.id, u.name, v.question, a.answer')
// join with Vote Entity
->leftJoin('r.vote' , 'v')
// join with User Entity
->leftJoin('r.user' , 'u')
// join with Answer Entity
->leftJoin('r.answer' , 'a')
// where id is same as $idVote
->andWhere('v.id = :id_vote')
->setParameter('id_vote', $idVote);
return $queryBuilder
->getQuery()
->getResult();
}
