我们如何在Symfony 2中使用doctrine执行此查询:
SQL:
SELECT p.* FROM messages, (SELECT * from posts ORDER BY created_at DESC) as p GROUP BY p.category_id ORDER BY message.created_at;
问题:每个表都必须是像MyProjectMyBundle这样的实体:MyEntity,(SELECT *来自帖子ORDER BY created_at DESC)不是实体......
Symfony 2(不起作用):
$query = $em->createQuery('SELECT p.*
FROM MyProjectMyBundle:Messages,
(SELECT * from posts ORDER BY created_at DESC) as p
GROUP BY p.category_id ORDER BY message.createdAt');
我们可以包含像Mysql这样的其他查询吗?一个解决方案?

我相信Doctrine不允许你在From语句中创建子查询。但是,您可以将常规sql键入doctrine。
