select * from
(select top 10 *
from (select top 20 *
from TABLE order by age) as TABLE1
order by age desc) as TABLE2
order by age;比如按照年龄排序,
首先,从TABLE中提取前20条记录,as为TABLE1;
然后,从TABLE1中倒序排列并提取前10条记录,as为TABLE2;
最后,显示查询记录,升序排列。

select *,identity(int,1,1) as id into #tmep from tb order by age
select * from temp where id between 11 and 20 --或
select * from
(select row_number() over (order by age) as id,* from tb) a
where id between 11 and 20
select top m * from tablename where id not in (select top n id from tablename order by id asc/*|desc*/) 2.
select top (n-m+1) * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入到临时表
set rowcount n --只取n条结果
select * from 表变量 order by columnname desc 3.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc
4.如果tablename里没有其他identity列,那么:
先生成一个序列,存储在一临时表中.
select identity(int) id0,* into #temp from tablename 取n到m条的语句为:
select * from #temp where id0 > =n and id0 <= m 如果你在执行select identity(int) id0,* into #temp from tablename这条语句的时候报错,那是因为你的DB中间的select into/bulkcopy属性没有打开要先执行:
exec sp_dboption 你的DB名字,'select into/bulkcopy',true
5.如果表里有identity属性,那么简单:
select * from tablename where identity_col between n and m 6.SQL2005开始.可以使用row_number() over()生成行号
;with cte as
(
select id0=row_number() over(order by id),* from tablename
)
select * from cte where id0 between n to m
select * from (select top 10 *
from (select top 20 *
from TABLE order by age) as TABLE1 order by age desc) as TABLE2
order by age;
