Sql Server 2005 ROW_NUMBER 函数实现分页_sql

概述过去用SQL Server 2000分页的，大多都用到了临时表。SQL Server 2005 ROW_NUMBER 函数支持分页，性能据说也非常不错。Paging Records Using S 过去用sql Server 2000分页的，大多都用到了临时表。sql Server 2005 ROW_NUMBER 函数支持分页，性能据说也非常不错。

最近MSDN Magazine上的一篇文章10 Tips for Writing High-Performance Web Applications提到了有效的数据分页技术对提高ASP .NET程序性能的重要性；并给出了一个实现数据分页的stored procedure的例子，抄录如下：

CREATE PROCEDURE northwind_OrdersPaged

(
@PageIndex int,
@PageSize int
)

AS
BEGIN
DECLARE @PageLowerBound int
DECLARE @PageUpperBound int
DECLARE @RowsToReturn int
-- First set the rowcount
SET @RowsToReturn = @PageSize * (@PageIndex + 1)
SET ROWCOUNT @RowsToReturn
-- Set the page bounds
SET @PageLowerBound = @PageSize * @PageIndex
SET @PageUpperBound = @PageLowerBound + @PageSize + 1
-- Create a temp table to store the select results
CREATE table #PageIndex
(
    IndexID int IDENTITY (1,1) NOT NulL,
    OrderID int
)
-- Insert into the temp table
INSERT INTO #PageIndex (OrderID)
SELECT
    OrderID
FROM
    Orders
ORDER BY
    OrderID DESC
-- Return total count
SELECT COUNT(OrderID) FROM Orders
-- Return paged results
SELECT
    O.*
FROM
    Orders O,
    #PageIndex PageIndex
WHERE
    O.OrderID = PageIndex.OrderID AND
    PageIndex.IndexID > @PageLowerBound AND
    PageIndex.IndexID < @PageUpperBound
ORDER BY
    PageIndex.IndexID
END
