本文提供了几种在SQL Server 2000/2005中实现分页查询的方法，包括使用NOT IN、子查询及ROW_NUMBER()函数等技术来获取特定页的数据。

适用于SQL2000/2005

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

适用2000/2005

代码

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

适用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)

代码

---處理時候用代碼增加個ID INT IDENTITY
--方法1：
--适用于 SQL Server 2000/2005
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
