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 ) as begin 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.CompanyID inner 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):
