hibernte+mysql纯sql查询问题

以下代码始终报错:

/** * 获得换车动态 * @return */public List<Object[]> getTransDynamic(){Object result = super.commonDao.execute(new IHibernateCallback() {public Object doInHibernate(Session session) {String sql ="select "+"(select ms.nickname from Memberstatus as ms where ms.MemberId=t.FPMemberId) as fpname, "+"(select ms.nickname from Memberstatus as ms where ms.MemberId=t.SPMemberId)  as spname, "+"(case t.Status "+"when '1' then '正在换车' "+"when '2' then '换车完成' "+"end) as st, "+"t.StartTime, "+"t.`FPMemberId` as fpid, "+"t.`SPMemberId` as spid "+"from `Transfer` as t "+"where t.Status in ('1','2') and t.EndTime<=sysdate() "+"order by t.StartTime "+"limit 0,7 ";return session.createSQLQuery(sql).list();}});return result==null?null:(List<Object[]>)result;}

错误信息如下：

观察控制台的输出：

    select
        (select
            ms.nickname
        from
            Memberstatus as ms
        where
            ms.MemberId=t.FPMemberId) as fpname,
        (select
            ms.nickname
        from
            Memberstatus as ms
        where
            ms.MemberId=t.SPMemberId)  as spname,
        (case t.Status 
            when '1' then '正在换车' 
            when '2' then '换车完成'
        end) as st,
        t.StartTime,
        t.`FPMemberId` as fpid,
        t.`SPMemberId` as spid
    from
        `Transfer` as t
    where
        t.Status in (
            '1','2'
        )
        and t.EndTime<=sysdate()
    order by
        t.StartTime limit 0,
        7

将以上sql粘贴到mysql工具中执行完全没有任何问题，这就怪了。

最后折腾处理如下：

select * from (原来的查询sql) as 别名

最后行了!

完整如下：

/** * 获得换车动态 * @return */public List<Object[]> getTransDynamic(){Object result = super.commonDao.execute(new IHibernateCallback() {public Object doInHibernate(Session session) {String sql ="select * from (" +"select "+"(select ms.nickname from Memberstatus as ms where ms.MemberId=t.FPMemberId) as fpname, "+"(select ms.nickname from Memberstatus as ms where ms.MemberId=t.SPMemberId)  as spname, "+"(case t.Status "+"when '1' then '正在换车' "+"when '2' then '换车完成' "+"end) as st, "+"t.StartTime, "+"t.`FPMemberId` as fpid, "+"t.`SPMemberId` as spid "+"from `Transfer` as t "+"where t.Status in ('1','2') and t.EndTime<=sysdate() "+"order by t.StartTime "+"limit 0,7 "+") as model";return session.createSQLQuery(sql).list();}});return result==null?null:(List<Object[]>)result;}
