我想从DQL中的子查询结果中执行SELECT.相当于在SQL中执行以下操作:

SELECT * FROM ( SELECT foo1,foo2 FROM bar ) where foo1='something';

我遇到的问题是它抱怨

Error: Class '(' is not defined

产生该错误的实际DQL是:

SELECT u FROM (
    SELECT u, COUNT(u) as total
        FROM Utterance u LEFT JOIN u.recordings r
        WHERE r.speaker IS NULL OR r.speaker <> 5
        GROUP BY u.id
    ) matched WHERE total < 5

重申一下,如何从子查询中执行选择？
