今天在网上看��C��(ji��n)几个解决sql2000的分��|��询方�?br>写在�q�里(没有��试)

四种�Ҏ(gu��)��取表里n到m条纪录：(x��)

1.
select top m * into 临时�?或表变量) from tablename order by columnname -- ��top m�W�插�?br>set rowcount n
select * from 表变�?order by columnname desc

2.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc

3.如果tablename里没有其他identity列，那么�Q?br>select identity(int) id0,* into #temp from tablename

取n到m条的语句为：(x��)
select * from #temp where id0 >=n and id0 <= m

如果你在执行select identity(int) id0,* into #temp from tablename�q�条语句的时候报�?那是因�ؓ(f��)你的DB中间的select into/bulkcopy属性没有打开要先执行�Q?br>exec sp_dboption 你的DB名字,'select into/bulkcopy',true

4.如果表里有identity属性，那么��单：(x��)
select * from tablename where identitycol between n and m
