SQLSERVER Pager store procedure分页存储过程

代码如下：

SET ANSI_NULLS ON 
GO 
SET QUOTED_IDENTIFIER ON 
GO 

CREATE PROCEDURE [dbo].[Pagination] 
@Page int = 1, -- 当前页码 
@PageSize int = 10, -- 每页记录条数(页面大小) 
@Table nvarchar(500), -- 表名或视图名，甚至可以是嵌套SQL：(Select * From Tab Where ID>1000) Tab 
@Field nvarchar(800) = '*', -- 返回记录集字段名，","隔开，默认是"*" 
@OrderBy nvarchar(100) = 'ID ASC', -- 排序规则 
@Filter nvarchar(500), -- 过滤条件 
@MaxPage smallint output, -- 执行结果 -1 error, 0 false, maxpage true 
@TotalRow int output, -- 记录总数 /* 2007-07-12 22:11:00 update */ 
@Descript varchar(100) output -- 结果描述
