没有order by 的 top n吗select top 100-n from table order by 排序字段 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 identity(int) id0,* into #temp from tablename select * from #temp where id0 > =n-100 and id0 <= n
取N-100太多了, 取N-2吧 -- ============================================= -- Author: T.O.P -- Create date: 20091201 -- Version: SQL SERVER 2000 -- ============================================= declare @tb table(q int) insert @tb select 1 union all select 2 union all select 3 union all select 4 union all select 5 --取N-2的记录select top 2 * from @tb order by q desc--测试结果: /*q ----------- 5 4(所影响的行数为 2 行) */
SELECT * FROM vehicle WHERE ROWNUM<=n minus SELECT * FROM vehicle WHERE ROWNUM<n-100;
select top 100+1 * from (select top n * from tablename ) as t order by id desc
第一个是oracle里,第二个是server里
表table,一共有n条记录,现在想取出n-100到n之间的记录! select top 100 * from [table] where id not in(select top (n-100) id from [table] order by id) order by id
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 * from #temp where id0 > =n-100 and id0 <= n
取N-100太多了, 取N-2吧
