数据库还是用Northwind数据库。就用Orders表为例子吧，假设每页都显示10条记录。
我们先查询第一页的数据。
SELECT *
FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY OrderID ) AS RowNumber ,
*
FROM Orders
) T
WHERE RowNumber BETWEEN 1 AND 10
这里用到一个函数ROW_NUMBER() OVER函数，这个函数的语法是ROW_NUMBER() OVER(PARTITION BY COLUMN ORDER BY COLUMN)
简单的说ROW_NUMBER()从1开始，为每一条分组记录返回一个数字，这里的ROW_NUMBER() OVER (ORDER BY OrderID) 是先把OrderID列升序，再为升序以后的每条记录返回一个序号。
接下来，查询第二页的数据。
SELECT *
FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY OrderID ) AS RowNumber ,
*
FROM Orders
) T
WHERE RowNumber BETWEEN 11 AND 20
由此可以推断出，第N页的数据为
SELECT *
FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY OrderID ) AS RowNumber ,
*
FROM Orders
) T
WHERE RowNumber BETWEEN (N-1)*10+1 AND N*10
写成通用的SQL语句如下：
BEGIN
DECLARE @PageSize INT --每页显示条数
DECLARE @PageIndex INT --页码（从1开始）
SET @PageSize = 10
SET @PageIndex = 2
SELECT *
FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY OrderID ) AS RowNumber ,
*
FROM Orders
) T
WHERE RowNumber BETWEEN ( ( @PageIndex - 1 ) * @PageSize + 1 )
AND ( @PageIndex * @PageSize )
ORDER BY OrderID ASC
END
写成存储过程如下：
--存储过程
CREATE PROCEDURE P_GetPagedOrders2
@PageSize INT , --每页显示条数
@PageIndex INT , --页码（从1开始）
@RecordCount INT OUTPUT , --数据总数
@PageCount INT OUTPUT --总页数
AS
BEGIN
--获取数据总数
SELECT @RecordCount = COUNT(1)
FROM dbo.Orders
--计算总页数
SET @PageCount = @RecordCount / @PageSize
IF @RecordCount % @PageSize > 0
BEGIN
SET @PageCount = @PageCount + 1
END
--获取当前页的数据
SELECT *
FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY OrderID ) AS RowNumber ,
*
FROM Orders
) T
WHERE RowNumber BETWEEN ( ( @PageIndex - 1 ) * @PageSize + 1 )
AND ( @PageIndex * @PageSize )
ORDER BY OrderID ASC
END
测试存储过程
DECLARE @RecordCount int,
@PageCount int
EXEC [P_GetPagedOrders2]
@PageSize = 10,
@PageIndex = 2,
@RecordCount = @RecordCount OUTPUT,
@PageCount = @PageCount OUTPUT
SELECT @RecordCount as N‘@RecordCount‘,
@PageCount as N‘@PageCount‘
测试结果如下
