谁能告诉我一下orader by的问题

Question

我在用access的时候，出现了一个问题，不知道为什么ORDER BY 不起作用，谁能帮我解答一下。

SELECT announce_master.counter

,(SELECT TOP 1 m_group.gname

FROM m_user,m_group,group_info

WHERE announce_master.uid = m_user.uid

AND m_user.uid = group_info.uid

AND m_group.gid = group_info.gid
AND group_info.uid = m_user.uid

AND m_group.gid <> '00000000000000000000000000000000'

AND m_group.gid <> '11111111111111111111111111111111'

ORDER BY m_group.viewid) as gname

FROM ((announce_master

LEFT OUTER JOIN m_user ON announce_master.uid = m_user.uid)

LEFT OUTER JOIN announce_category ON announce_master.category_id = announce_category.category_id)

WHERE

announce_master.counter IN (28,9,10,11,12,29,30)

ORDER BY 2 ASC

Answer 1

1、刚才没看见，你用了两个Order by ，Order by和top一起用的时候可能查出来多于你要的结果

2、order by 不支持表达式
