毫秒级百万数据分页存储过程

然后创建分页存储过程;这个是基于SQL 2005 的ROW_NUMBER的, SQL 2000 不适用; SQL 2008 我没有安装,所以也没有测试过!估计应该可以运行.

2种算法可以选择 1. 使用 BETWEEN ; 2. TOP ; 代码中已经注释了.

我测试了一下2种方法基本没有什么区别;代码如下:

  USE [DATA_TEMP]
 GO
 /****** 对象:  StoredProcedure [dbo].[im531_Page]    脚本日期: 11/26/2010 10:52:35 ******/
 SET ANSI_NULLS ON
 GO
 SET QUOTED_IDENTIFIER ON
 GO
