sqlServer千万数量级分页公共存储过程

 

通用的数据库分页存储过程：

if exists (select * from dbo.sysobjects where ID = object_ID(N'[dbo].[UP_Pagination]') and OBJECTPROPERTY(ID,N'IsProcedure') = 1)
drop procedure [dbo].[UP_Pagination]
GO

SET QUOTED_IDENTIFIER OFF 
GO
SET ANSI_NulLS OFF 
GO

CREATE PROCEDURE UP_Pagination

** 千万数量级分页存储过程 **
***************************************************************
参数说明:
1.tables :表名称,视图,多表查询可用视图做
2.PrimaryKey :主关键字
3.sort :排序语句，不带Order By 比如：NewsID Desc,OrderRows Asc
4.CurrentPage :当前页码
5.PageSize :分页尺寸
6.FIElds :查询字段,默认为 *
6.Filter :过滤语句，不带Where 
7.Group :Group语句,不带Group By
