在Symfony 2中是否有更好的方法来构建复杂查询?我的真实查询非常复杂,但可以简化为"A和((B和C)或(B和D))"之类的东西(我知道数学方程是"A和B和(C或D)",但我的真实询问无法简化)。我有使用andWhere和orX的经验,但我的问题是如何在'orX'内部使用'and'/'expr()->andX'。
下面的例子(问题是关于orX内部的伪代码部分):
$qBuilder = $repo->createQueryBuilder('s')
->select('s.id')
->Where('s.FirstName = :fname')
->Where('s.LastName = :lname')
->andWhere($qBuilder->expr()->orX(
(':email is not empty AND s.Email = :email'),
(':phone is not empty AND s.HomePhone = :phone ),
(':phone is not empty AND s.StudentMobile = :phone ),
(':mphone is not empty AND s.HomePhone = :mphone),
(':mphone is not empty AND s.StudentMobile = :mphone)
))
->setParameter('fname', strtolower($fname))
->setParameter('lname', strtolower($lname))
->setParameter('email', $email)
->setParameter('phone', $phoneNumber)
->setParameter('mphone', $studentmobile);
只需在内部创建一个andX()
表达式。所有表达式函数都是可嵌套的
->andWhere($qb->expr()->orX(
$qb->expr()->andX(':email is not empty', 's.Email = :email'),
$qb->expr()->andX(':phone is not empty', 's.HomePhone = :phone'),
$qb->expr()->andX(':phone is not empty', 's.StudentMobile = :phone'),
$qb->expr()->andX(':mphone is not empty', 's.HomePhone = :mphone'),
$qb->expr()->andX(':mphone is not empty', 's.StudentMobile = :mphone')
))
