Symfony DQL Postgresql组不工作

Question

我刚从mysql切换到postgresql，我的工作dql查询停止工作。

这是我的dql

SELECT p
        FROM AppBundle:Photo p
                JOIN AppBundle:Like l  WITH p = l.photo
           WHERE p.isModerated = :isModerated
            AND p.isActive = :isActive
                        AND p.category IN(:categories)
                        AND p.creationDate <= :begin
                        AND p.creationDate >= :end
                        GROUP BY p.id
            ORDER BY l.creationDate DESC

获取下一个错误

SQLSTATE[42803]: Grouping error: 7 ERROR: column "l1_.creation_date" must appear in the GROUP BY clause or be used in an aggregate function
LINE 1: ... p0_.creation_date >= $4 GROUP BY p0_.id ORDER BY l1_.creati...

据我所知，它表示按列分组应该在SELECT中。我不是在那里。我只需选择p（AppBundle：Photo），仅此而已。应该在dql中编辑什么才能使其正常工作？

谢谢。

Answer 1

我刚刚将ORDER BY l.creationDate DESC替换为ORDER BY p.creationDate DESC

它对我有用。据我所知，ORDER BY列应该是SELECTed
