同一条sql语句内有两个相同的子查询，有没有什么好方法优化下？？？
如题：

sql语句如下：

SQL code

select top 15 * from ( select * from table where sid=1004 ) as M  where id > (select max (id)                from (select top (15 * (20 - 1)) id                        from ( select * from table where sid=1004 ) as M                      where order by id                     ) as T              ) order by id

就是一个旧系统中的分页语句，
想稍微优化下，
想到用表变量，
但觉得好麻烦，
希望各位给出更好的方法

为什么不分开来写呢？

select * into #a from table where sid=1004
select top (15 * (20 - 1)) id itno #b from #a where order by id
select top 15 * from #a where id > (select max (id) from #b ) order by id

--修正一下，刚才变量写返了

SQL code

declare @pagesize int set @pagesize=15 --每页15条declare @pageindex int set @pageindex=2 --第20页;with maco as(    select row_number() over (order by id) as num,* from [table] where sid=1004)select * from maco where num between (@pagesize*(@pageindex-1)+1) and @pageindex*@pagesize
