1.
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
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:
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
4.
如果表里有identity属性,那么简单:
select * from tablename where identitycol between n and m
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
2.
select top n * from
(select top m * from tablename order by columnname) a
order by columnname desc

如果表里有identity属性,那么简单:
select * from tablename where identitycol between n and m
tb_userinfo.age,tb_userinfo.cname,tb_userinfo.ctype,tb_userinfo.cpic_60
from tb_friendship inner join tb_userinfo on tb_friendship.cid= tb_userinfo.cid
group by tb_friendship.cid,tb_userinfo.cname,tb_userinfo.ctype,tb_userinfo.ctype,
tb_userinfo.cpic_60,tb_userinfo.age)
选择的字段太多了.
tb_userinfo.age,tb_userinfo.cname,tb_userinfo.ctype,tb_userinfo.cpic_60 from tb_friendship inner join tb_userinfo on tb_friendship.cid= tb_userinfo.cid
where tb_userinfo.cid not in (select top 3 tb_friendship.cid
from tb_friendship inner join tb_userinfo on tb_friendship.cid= tb_userinfo.cid )
group by tb_friendship.cid,tb_userinfo.cname,tb_userinfo.ctype,tb_userinfo.ctype,
tb_userinfo.cpic_60,tb_userinfo.age

5.如果表里有identity属性,那么简单:
select * from tablename where identitycol between n and m 如果是sql server 2005 可以这样写:
select top 20 * from T order col
except
select top 2 * from T order col
