create table a
(
typeid int,
styelid int,
userid int
)
insert into a (1,1,1) insert into a (1,1,2) insert into a (1,1,3)
insert into a (1,2,4) insert into a (1,2,5) insert into a (1,2,6)
insert into a (1,3,7) insert into a (1,3,8) insert into a (1,3,9)
insert into a (2,1,10) insert into a (2,1,11) insert into a (2,1,12)
insert into a (2,2,13) insert into a (2,2,14) insert into a (2,2,15)
insert into a (2,3,16) insert into a (2,3,17) insert into a (2,3,18)
根据上面的测试数据,我想要得到每种typeid的每种Style的前2条记录,不想用游标,用游标的话可以解决,但是速度太慢了.
看哪位大哥可以帮下忙的,谢谢了
