谁来帮忙优化一下这条SQL语句

[wangfei99168]

其实就是从视图中搜索第16条记录之后的15条记录。
使用的数据库为SQL 2000
求更优化的语句！！

SELECT * FROM V_view WHERE sortID =89 AND id IN (SELECT TOP 15 id FROM V_view WHERE sortID =89 AND id NOT IN(SELECT TOP 15 id FROM V_view WHERE sortID =89 ORDER BY id desc ) ORDER BY id desc ) ORDER BY id desc

谢谢大侠们！

select top 15 * from (
select top(16+15) * from tb order by id desc
) aa order by id desc

[LMAOhuaNL]

select top 15 * from (
select top(16+15) * from tb order by id desc
) aa order by id desc

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 15 * from tb
where id not in 
(select top 16 id from tb order by id asc/*|desc*/) 
order by id asc/*|desc*/

[我腫了]

select top 31 * from tb
except
select top 16 * from tb

取第十六条到第二十条
select top 30 * from tb
except
select top 15 * from tb

[Quote=引用 8 楼 bbbbbben 的回复:]
取第十六条到第二十条
select top 30 * from tb
except
select top 15 * from tb
[/Quote]


又打错了 是 取第十六条到第三十条

[Warren]

应该和“先降序取30条，在从这30条里升序去15条”等价吧？

;with DESC_top30
as
(
  select top 30 *
  from V_view 
  where sortID = 89
  order by ID desc
)
select top 15 *
from DESC_top30
order by ID asc 

[xiaoxiangqing]

SELECT top 15 * FROM V_view WHERE sortID =89 AND id IN (select top 30 id FROM V_view WHERE sortID =89 order by id desc) order by id desc
