hibernte+mysql纯sql查询问题

以下代码始终报错: /** * 获得换车动态 * @return */public ListObject[] getTransDynamic(){Object result = super.commonDao.execute(new IHibernateCallback() {public Object doInHibernate(Session session) {String sql =select +(select ms.nickname

以下代码始终报错:

/**
	 * 获得换车动态
	 * @return
	 */
	public List 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)result;
	}

错误信息如下：

观察控制台的输出：

Hibernate:
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
2013-59-03 10:59:26could not read column value from result set: FPMemberId; Column 'FPMemberId' not found.

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 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)result;
	}
