请教如何实现查询第20至30条数据？

[cakexiang]

就像MYSQL里边的limit

[xiangchengboy]

很经典的题目：select top 30 * from table where id not in(select top 20 id from table order by id asc) order by id asc

Thanks a lot

取n到m行

1. 
select top m * from tablename where id not in (select top n id from tablename order by id asc/*|desc*/) 

2. 
select top m * 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 top 10 *
from
(
select top 30 * from tb) t
order by XX desc

[SQL77]

SELECT IDD=IDENTITY(INT,1,1),* INTO #T FROM TB
SELECT * FROM #T WHERE IDD BETWEEN 20 AND 30

多种方法，学习。。。

[yyyyyhhhhwwww]

[Quote=引用 4 楼 sql77 的回复:]
SQL codeSELECT IDD=IDENTITY(INT,1,1),*INTO #TFROM TBSELECT*FROM #TWHERE IDDBETWEEN20AND30
[/Quote]

此解较不错！顶了！

[caobingyi]

学习了

[zhu_chuan_hang]

select top 10 *
from(select top 30 * from tb)
order by X desc
