简单来说就是

create table #firsttable (orderid INT PRIMARY KEY IDENTITY(1,1),tableid2 int)
临时表
insert into #firsttable(tableid2) select top 20 id from dbo.TABLE1 t1 order by t1.aa desc, t1.id
比如查21-30的数据,那查出前30个记录插入到临时表中
select tableid2,dbo.TABLE1.* from #firsttable inner join dbo.TABLE1 on #firsttable.tableid2=dbo.TABLE1.id where orderid>(select max(orderid) from (select top 10 orderid from #firsttable) as t) order by orderid
drop table #firsttable
临时表中把id>第20条的数据取出来,剩下的就是要的数据,用inner join 联合查出.

后来我又发现一个更高效的

先说说基本原理，比如3页，每页10条，就是求21-30条数据，总共30条记录我们是知道的，用
set Rowcount 30设置只查前30条数据，用@n=10(pagesize) select @n=@n-1,Case @n<10 then @sql=sql+id+',' from 从而得到21,22,23,24....30字符串，＠n<10代表从上往下数，最后10个

--如果@PageCount为NULL值,则计算总页数(这样设计可以只在第一次计算总页数,以后调用时,把总页数传回给存储过程,避免再次计算总页数,对于不想计算总页数的处理而言,可以给@PageCount赋值)
