每次只取固定行数的sql语句

select top 10 *
from(
select top 20 * from EMP order by sal ) a
order by a.sal desc

有主键：
select top 10 * from 表 where 主键 not in(select top 10 主键 from 表)
没有主键：
select id=identity(int,1,1),* into #tb from 表
select * from #tb where id between 11 and 20

declare @i int
set @i=0
select top 10 * from death where id between (1+10*i) and (10+(10*i))
set @i=@i+1

create proc getTop
as
declare @i int
set @i=0
select top 10 * from death where id between (1+10*i) and (10+(10*i))
set @i=@i+1

select top 10 * from
(
select top 20 * from death order by id
)
a order by a.id desc

--取n到m条记录的语句 --1.
select top m * from tablename where id not in (select top n id from tablename) --2.
select top m * into 临时表(或表变量) from tablename order by columnname -- 将top m笔插入
set rowcount n
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：
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 identitycol between n and m

用minus关键字可实现集合的相减select top 20 * from test
minus
select top 10 * from test
可得到11~20条记录同理：
select top 30 * from test
minus
select top 20 * from test
可得到21~30条记录

以上可得到原始顺序的区间记录，优于用order得到的结果
