SQL问题
我有一个新闻类别表，其有10个类别。还有个新闻表，有各个类别的新闻。
我想查询新闻表中各个类别的前5条新闻。这该怎么弄？
[解决办法]
简单写了一个.放到查询分析器里直接执行即可
try it!
declare @type table(tid int,tname varchar(50))declare @news table(nid INT IDENTITY (1,1),tid int,news varchar(100))insert into @type values(1,'A')insert into @type values(2,'B')insert into @type values(3,'C')insert into @news values(1,'xxx1')insert into @news values(1,'xxx2')insert into @news values(1,'xxx3')insert into @news values(1,'xxx4')insert into @news values(1,'xxx5')insert into @news values(1,'xxx6')insert into @news values(1,'xxx7')insert into @news values(2,'xxxa1')insert into @news values(2,'xxxb2')insert into @news values(2,'xxxc3')insert into @news values(2,'xxxd4')insert into @news values(2,'xxxe5')insert into @news values(2,'xxxf6')insert into @news values(2,'xxxf7')select * from @news ns where ns.nid in (select top 5 nid from @news n where n.tid = ns.tid)
