查询结果中,如何取指定行的前10行和后10行的数据?
按条件查询出来的记录有100条,我想取指定行的前10行和后10行,比如指定第30行,也就是要取出第20行到第40行间的数据改如何取呢?其中有ID标识
------解决方案--------------------取n到m条记录的语句
1.
select top m * from tablename where id not in (select top n * 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
