关键每类都有两条数据.也就是说每类最多只两条.如5类查询出来是最多10条,4类查询出来的最多是8条
[解决办法]
需要用吗？
如果需要用，关联一下就可以了。
[解决办法]
SELECT A.*,c.name --加C.name
FROM News as A,bigclass C --加bigclass C
where A.bigclassid=c.bigclassid and --加A.bigclassid=c.bigclassid and 连接条件
cid in (select top 2 cid from News where bigclassID=A.bigclassID order by cid des)
corder by a.bigclassid,a.cid desc--加排序
