文章有二个实例一个是sql2000的分页存储过程一个是sql2005的分页存储过程，有需要的同学可以拿去看看。

代码如下

CREATE PROCEDURE [dbo].[ProcCustomPage]
(
@Table_Name varchar(5000), --表名
@Sign_Record varchar(50), --主键
@Filter_Condition varchar(1000), --筛选条件,不带where
@Page_Size int, --页大小
@Page_Index int, --页索引
@TaxisField varchar(1000), --排序字段
@Taxis_Sign int, --排序方式 1为 DESC, 0为 ASC
@Find_RecordList varchar(1000), --查找的字段
@Record_Count int --总记录数
)
AS
BEGIN
DECLARE @Start_Number int

PRINT @sSQL

代码如下

CREATE PROCEDURE [dbo].[GetRecordFromPage]
