SQL Server 目前用到的两个分页存储过程

这篇文章主要为大家详细介绍了SQL Server 目前用到的两个分页存储过程，具有一定的参考价值，可以用来参考一下。

对此感兴趣的朋友，看看idc笔记做的技术笔记！

代码如下:

 
set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
go 
ALTER PROCEDURE [sq8reyoung].[fenye_num] 
( 
@TableNames NVARCHAR(200), 
@Filter nvarchar(200)) 
AS 
IF @Filter = '' 
SET @Filter = ' WHERE 1=1' 
ELSE 
SET @Filter = ' WHERE ' + @Filter 
EXECUTE('select count(*) from '+@TableNames+' '+@Filter) 

代码如下:

 
set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
go 
ALTER PROCEDURE [sq8reyoung].[fenye] 
@TableNames VARCHAR(200), --表名，可以是多个表，但不能用别名 
@PrimaryKey VARCHAR(100), --主键，可以为空，但@Order为空时该值不能为空 
@Fields VARCHAR(200), --要取出的字段，可以是多个表的字段，可以为空，为空表示select * 
@PageSize INT, --每页记录数 
@CurrentPage INT, --当前页，0表示第1页 
@Filter VARCHAR(200) = '', --条件，可以为空，不用填 where 
@Group VARCHAR(200) = '', --分组依据，可以为空，不用填 group by 
@Order VARCHAR(200) = '' --排序，可以为空，为空默认按主键升序排列，不用填 order by

END 
DECLARE @type varchar(50) 
DECLARE @prec int

SET @type = @type + '(' + CAST(@prec AS varchar) + ')' 
DECLARE @TopRows INT

DECLARE @sql NVARCHAR(4000)
