取n到m条记录的语句？未作测试，仅作参考。

1.
select top m * from tablename where id not in (select top n id 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 

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

SELECT TOP 页大小 *
FROM table1
WHERE id NOT IN
          (
          SELECT TOP 页大小*(页数-1) id FROM table1 ORDER BY id
          )
ORDER BY id
--方法2：
--适用于 SQL Server 2000/2005
SELECT TOP 页大小 *
FROM table1
WHERE id >
          (
          SELECT ISNULL(MAX(id),0) 
          FROM 
                (
                SELECT TOP 页大小*(页数-1) id FROM table1 ORDER BY id
                ) A
          )
ORDER BY id
--方法3：
--适用于 SQL Server 2005
SELECT TOP 页大小 * 
FROM 
        (
        SELECT ROW_NUMBER() OVER (ORDER BY id) AS RowNumber,* FROM table1
        ) A
WHERE RowNumber > 页大小*(页数-1)
--方法四 适用于 SQL Server 2005
DECLARE @pagenum AS INT, @pagesize AS INT 
SET @pagenum = 2 
SET @pagesize = 3 
SELECT * 
FROM (SELECT ROW_NUMBER() OVER(ORDER BY newsid DESC) AS rownum, 
        newsid, topic, ntime, hits 
      FROM news) AS D 
WHERE rownum BETWEEN (@pagenum-1)*@pagesize+1 AND @pagenum*@pagesize 
ORDER BY newsid DESC
说明，页大小：每页的行数；页数：第几页。使用时，请把“页大小”和“页大小*(页数-1)”替换成数字。
