[数据库]SQL Server利用RowNumber()内置函数与Over关键字实现通用分页存储过程(支持单表或多表结查集分页)


SQL Server利用RowNumber()内置函数与Over关键字实现通用分页存储过程,支持单表或多表结查集分页,存储过程如下:

/******************/--Author:梦在旅途(www.Zuowenjun.cn)--CreateDate:2015-06-02--Function:分页获取数据/******************/create procedure [dbo].[sp_DataPaging](@selectsql	nvarchar(200),--查询字段SQL,不含select,支持灵活写法,如:col1,col3,isnull(col4,'') as col4@fromsql	nvarchar(500),--查询表及条件SQL,不含from,若包含条件请加上where,如:table where col1='test'@orderbysql nvarchar(100),--查询排序SQL,不含order by,如:id order by desc@pagesize	int=20,--每页显示记录数@pageno		int=1,--当前查询页码,从1开始@returnrecordcount bit=1 --是否需要返回总记录数,若设为1,则返回两个结果表)asbegin	declare @sqlcount nvarchar(500),@sqlstring nvarchar(max)		set @sqlstring=N'from (select row_number() over (order by ' + @orderbysql + N') as rowId,' + @selectsql + N' from '				+ @fromsql +N') as t'	if(@returnrecordcount=1)	begin		set @sqlcount=N'select count(rowId) as resultcount ' + @sqlstring		exec(@sqlcount)	end	set @sqlstring=N'select * ' + @sqlstring + ' where rowId between ' + convert(nvarchar(50),(@pageno-1)*@pagesize+1)+' and '+convert(nvarchar(50),@pageno*@pagesize)		exec(@sqlstring)	end

 用法如下:

--单表查询exec [dbo].[sp_DataPaging] '*','AssetDetail','assetsingleno',10,1--多表查询exec [dbo].[sp_DataPaging] 'a.*','Inventory a left join AssetDetail b on a.StoreNo=b.StoreNo and a.CompanyID=b.CompanyIDinner join Asset c on b.AssetID=c.ID and b.CompanyID=c.CompanyID','a.id',20,3,1

结果显示如下(如上多表查询):
