Question

我尝试在单个表上的单个查询中检索多个计数。

return $this->getEntityManager()->createQuery(
        'SELECT COUNT(c1) AS enabled, COUNT(c2) AS disabled, COUNT(c3) AS locked
        FROM AcmeUserBundle:User c1, AcmeUserBundle:User c2, AcmeUserBundle:User c3
        WHERE c1.enabled = 1
        AND c2.enabled = 0
        AND c3.locked = 1'
    )->getSingleResult();

通过这个动作，我得到了这个结果：

array [
  "enabled" => "4"
  "disabled" => "4"
  "locked" => "4"
]

我期望的结果是：

array [
  "enabled" => "2"
  "disabled" => "1"
  "locked" => "1"
]

我得到了整个表格的简单计数。

有些人知道我能做到吗？

SQL查询错误。您正在进行三个表的交叉连接，但是您想要计算满足表中某些条件的行：

SELECT SUM(CASE WHEN u.enabled = 1 THEN 1 ELSE 0 END) as enabled,
       SUM(CASE WHEN u.enabled = 0 THEN 1 ELSE 0 END) as disabled,
       SUM(CASE WHEN u.locked = 1 THEN 1 ELSE 0 END) as locked
FROM AcmeUserBundle:User u

Symfony主义多重计数
