mysql - Symfony2 查询语法错误

Question

您好，我有以下联接查询。

return $this->getEntityManager()
        ->createQuery(
            "SELECT t1.taskId,t1.title,t1.dueDate,t1.modified,cb.forename,cb.surname,up.profilePhotoPath,
            (SELECT tp.metaData,tp.content FROM AppBundle:J1TaskPost tp order by tp.created DESC ) AS taskPost
            FROM AppBundle:J1Task as t1
            JOIN t1.assignees As ta
            JOIN t1.createdBy As cb
            JOIN AppBundle:J1UserProfile as up WITH t1.createdBy = up.user
            WHERE t1.deleted IS NULL and t1.status = false and ta.userid=$userId group by t1.taskId order by tp.created desc"
        )->getResult();

它抛出以下错误:

Syntax Error] line 0, col 130: Error: Expected Doctrine\ORM\Query\Lexer::T_FROM, got ','.

我无法找出上述查询中缺少的内容。

问题出在这一行:

"SELECT t1.taskId,t1.title,t1.dueDate,t1.modified,cb.forename,cb.surname,up.profilePhotoPath,
(SELECT tp.metaData,tp.content FROM AppBundle:J1TaskPost tp order by tp.created DESC ) AS taskPost

您需要选择taskPost 中的项目，但您在这里所做的是定义表。你可以做的是:

SELECT t1.taskId,t1.title,t1.dueDate,t1.modified,cb.forename,cb.surname,up.profilePhotoPath, taskPost.metaData, taskPost.content FROM
(SELECT tp.metaData,tp.content FROM AppBundle:J1TaskPost tp order by tp.created DESC ) AS taskPost,
