Question

我正在尝试在DQL中加入2个查询，但我收到的错误是，

[Semantical Error] line 0, col 114 near '(select u.email': Error: Class '(' is not defined. 我经历过 https://stackoverflow.com/questions/24600439/error-in-nested-subquery-in-dql-class-is-not-defined。但我无法弄明白。请帮忙。我的查询如下：

     $filterQuery = "SELECT tempResult1.email as email,tempResult1.name as name , tempResult1.id as user 
                    FROM (select u.email as email,a.name as name , u.id as user
                    FROM
                        Application\Entity\Userhasrole  uhr 
                        INNER JOIN 
                        Application\Entity\Oauthrole r with uhr.applicationrole = r.id
                        INNER JOIN
                        Application\Entity\Application a with r.application = a.id
                        INNER JOIN
                        Application\Entity\Oauthusers u 

                    ) tempResult1
                    LEFT JOIN 
                    (SELECT uhr1.user as user  FROM Application\Entity\Userhasrole  uhr1 where 
                      a.id = :applicationId
                    ) tempResult2
                    with tempResult1.user = tempResult2.user";
    $queryObject = $this->getEntityManager()
            ->createQuery($filterQuery);
    $queryObject->setParameter('applicationId', $applicationId);
    $result = $queryObject->getResult();

你混合了Doctrine2的两个概念：

使用SQL
使用DQL

如果要实现所需，建立表选择而不是实体选择，则应使用EntityManager::createNativeQuery()方法并将SQL查询设置为参数。

EntityManager::createQuery()仅用于DQL查询

加入2会导致Doctrine抛出错误
