我有两个实体 Person 和 Nursery,它们之间有一个ManyToMany
关系,有一个JoinTable
。我想进行这个 2 个 sql 查询:
1) 找到与托儿所相关的所有员工(= 人)nursery_id
select p.* from person p inner join nursery_staff ns on p.id = ns.staff_id inner join nursery n on ns.nursery_id = n.id where n.id=1 and p.nursery_staff_role <> 'MANAGER';
2)找到有staff_id的工作人员,并确保他与托儿所有联系nursery_id
select p.* from person p inner join nursery_staff ns on p.id = ns.staff_id inner join nursery n on ns.nursery_id = n.id where n.id=2 and p.id=4 and p.nursery_staff_role <> 'MANAGER';
为此,我在 PersonRepository 中有以下 2 个查询:
1 )
public function findAllStaffLinkedToANursery($nursery_id)
{
$qb = $this->_em->createQueryBuilder();
$qb->select('p')
->from($this->_entityName, 'p')
->innerJoin('VSCrmBundle:Nursery', 'n')
->where('n.id = :id')
->andWhere('p.nurseryRole <> :profession')
->setParameters(array('id' => $nursery_id, 'profession' => 'MANAGER'));
return $qb->getQuery()->getResult();
}
2)
public function findOneByNurseryAndStaffId($nursery_id, $staff_id)
{
$qb = $this->_em->createQueryBuilder();
$qb->select('p')
->from($this->_entityName, 'p')
->innerJoin('VSCrmBundle:Nursery', 'n')
->where('p.id = :pid')
->andWhere('n.id = :nid')
->andWhere('p.nurseryRole <> :staffRole')
->setParameters(array(
'pid' => $staff_id,
'nid' => $nursery_id,
'staffRole' => 'MANAGER'
));
return $qb->getQuery()->getOneOrNullResult();
}
但在这两种情况下,查询都不关心nursery_id,这给了我不受nursery_id依赖的工作人员。例如,id=4 的人与 id=2 的托儿所没有链接,但此查询向我显示了此人。
编辑:我对 dql 查询有相同的结果:
php bin/console doctrine:query:dql "select p.email from VSCrmBundle:Person p inner join VSCrmBundle:Nursery n where n.id=2 and p.nurseryRole <> 'MANAGER'"
也许这是您加入托儿所实体的方式。尝试从 Person 实体属性加入它,如下所示:
public function findAllStaffLinkedToANursery($nursery_id)
{
$qb = $this->_em->createQueryBuilder();
$qb->select('p')
->from($this->_entityName, 'p')
->innerJoin('p.nursery', 'n')
->where('n.id = :id')
->andWhere('p.nurseryRole <> :profession')
->setParameters(array('id' => $nursery_id, 'profession' => 'MANAGER'));
return $qb->getQuery()->getResult();
}
这当然只在人具有托儿所属性并且与教义 ORM 映射的情况下才有效。如果存储库扩展了 Doctrine\ORM\EntityRepository,您还可以简化它:
public function findAllStaffLinkedToANursery($nursery_id)
{
$qb = $this->createQueryBuilder('p');
$qb->innerJoin('p.nursery', 'n')
->where('n.id = :id')
->andWhere('p.nurseryRole <> :profession')
->setParameters(array('id' => $nursery_id, 'profession' => 'MANAGER'));
return $qb->getQuery()->getResult();
}
好的,感谢塞普尔图拉,我的代码可以工作!我说这个:
public function findAllStaffLinkedToANursery($nursery_id)
{
$qb = $this->createQueryBuilder('p');
$qb->innerJoin('p.nurseries', 'n')
->where('n.id = :id')
->andWhere('p.nurseryRole <> :profession')
->setParameters(array('id' => $nursery_id, 'profession' => 'MANAGER'));
return $qb->getQuery()->getResult();
}
