有没有更好的方法在 Symfony 2 中构建复杂查询?我的真实查询非常复杂,但可以简化为“A and ((B and C) or (B and D))”(我知道数学方程为“A and B and (C or D)”,但是我的真实查询无法简化)。我有使用andWhere 和orX 的经验,但我的问题是如何在'orX' 中使用'and' / 'expr()->andX'。

下面的示例(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andX()里面做一个 expr 。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')
))
