求教个查询的语句！！！！！！！
select   top   20   *   from   users   order   by   id
用这条语句选出从users中选出20条数据后，怎么在从这20条中选择10条出来。
选择这20条的后10条。

------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
