我有两个实体,Order和Orderline,具有一对多的关系。我有一个列表,我只需要订单中的数据,但是Doctrine会查询每个订单的订单。我没有在查询中加入Orderlines。如何阻止Doctrine查询订单?
控制器中使用的查询:
$query = $em->createQuery("SELECT o FROM SomeBundle:Order o JOIN o.shop s JOIN s.user u WHERE u.id = :user_id AND o.status = :status")
->setParameter('user_id', $user->getId())
->setParameter('status', 'paid');
$orders = $query->getResult();
Order类中的一对多注释:
/**
* @ORM\OneToMany(targetEntity="Orderline", mappedBy="order")
*/
protected $orderlines;
Orderline类中的多对一注释:
/**
* @ORM\ManyToOne(targetEntity="Order", inversedBy="orderlines")
*/
protected $order;
答案 0 :(得分:5)
使用Doctrine\ORM\Query::HINT_FORCE_PARTIAL_LOAD
提示学说$query = $em->createQuery("SELECT partial o.{id} FROM SomeBundle:Order o JOIN o.shop s JOIN s.user u WHERE u.id = :user_id AND o.status = :status")
->setParameter('user_id', $user->getId())
->setParameter('status', 'paid');
$query->setHint(Doctrine\ORM\Query::HINT_FORCE_PARTIAL_LOAD, 1);
$orders = $query->getResult();
OR
