Sql server 2005带来的分页便利

核心提示：select threadid from (select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads) as T where T.Pos > 100000 and T.Pos < 100030===如果里面

select threadid from
(
select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads
) as T
where T.Pos > 100000 and T.Pos < 100030

===========================================

如果里面的这个表cs_threads数据量超大，比如，几亿条记录，那这个方法应该是有问题的

因为，select threadid from
(
select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads
) as T
where T.Pos > 100000 and T.Pos < 100030
这个语句是把select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads它全部取出来，然后在SQL的外面进行分页的，没在SQL2005上测试过，因为原先在Oracle(大型网站数据库平台)上这样的写法是不好的，Oracle(大型网站数据库平台)中这样写比较好：select threadid from
(
select threadid, ROW_NUMBER() OVER (order by stickydate) as Pos from cs_threads a where a.pos<100030
) as T
where T.Pos > 100000
