Question

我有以下HQL

SELECT distinct demand  FROM MyDemand demand  
where demand in (   SELECT invd FROM MyDemand invd    
                      JOIN invd.MyDemandLine line    
                      JOIN line.Restr restr    
                where restr.Order=:order)

问题是生成的SQL是：

...........
 where
        (
            inventoryd0_.id, inventoryd0_.invNo
        ) in (
            select
                (inventoryd6_.id,
                inventoryd6_.invNo)
            from
                MyDemand inventoryd6_ 
................

问题是sql在＆＃34;，＆＃34;失败了。来自＆＃34; inventoryd6_.id，inventoryd6_.invNo＆＃34;。如果我从SQL中删除环境括号，一切正常。我使用Hibernate 3。?.这是休眠中的错误还是我做错了什么？

我将查询更改为：

SELECT distinct demand  FROM MyDemand demand  
where exists (   SELECT 'x' FROM MyDemand invd    
                      JOIN invd.MyDemandLine line    
                      JOIN line.Restr restr    
                where restr.Order=:order
                  and invd=demand)

Hql选择里面的子句
