SQL存储过程分页(通用的拼接SQL语句思路实现)
多表通用的SQL存储过程分页
案例一:
USE [Community] GO /****** Object: StoredProcedure [dbo].[Common_PageList] Script Date: 2016/3/8 13:44:58 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[Common_PageList] ( @tab nvarchar(200),---表名 @strFld nvarchar(max), --字段字符串 @strWhere nvarchar(max), --where条件 @PageIndex int, --页码 @PageSize int, --每页容纳的记录数 @Sort nvarchar(255), --排序字段及规则,不用加order by @Total int output --总数 ) AS declare @strSql nvarchar(max) set nocount on; set @strSql=' SELECT * FROM (SELECT ROW_NUMBER() OVER(ORDER BY ' + @Sort + ') AS rownum, ' + @strFld + ' FROM ' + @tab + ' where 1=1 ' + @strWhere + ') AS Dwhere WHERE rownum BETWEEN ' + CAST(((@PageIndex-1)*@PageSize + 1) as nvarchar(20)) + ' and ' + cast((@PageIndex*@PageSize) as nvarchar(20)) exec (@strSql) --print @strSql set @strSql='SELECT @Total = COUNT(0) FROM ' + @tab + ' WHERE 1=1 ' + @strWhere --print @strSql EXECUTE sp_executesql @strSql,N'@Total INT OUTPUT',@Total OUTPUT set nocount off; GO
分页功能可以简化整合成统一的 SQL语句分页壳子 功能:
USE [Community] GO /****** Object: StoredProcedure [dbo].[GetMySocialList] Script Date: 2016/3/17 15:20:18 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author: 熊学浩 -- Create date: 2016-03-17 -- Description: “我的圈子"列表 -- ============================================= CREATE PROCEDURE [dbo].[GetMySocialList] -- Add the parameters for the stored procedure here @MemberID int, --用户ID @PageIndex int, --页码 @PageSize int, --每页容纳的记录数 @Total int output --总数 AS declare @strSql nvarchar(max); BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; --主查询 set @strSql='SELECT S.CMSocialID, S.SocialName, S.SocialDescription, S.SocialLogo, S.SocialAuthority, S.Integral, S.SocialState, S.IsAvailable, SC.CheckState, SC.Notes, SM.CMSocialMemberID, SM.MemberID, SM.MemberName, SM.MemberIntegral, SM.EnterTime, SM.MemberState, SM.MemberRank, SM.IsRecommend FROM (SELECT * FROM CMSocialMember WHERE MemberID='+ CAST(@MemberID as nvarchar(20))+' AND IsDelete<>1 AND IsAvailable=1) AS SM INNER JOIN CMSocial AS S ON S.CMSocialID=SM.CMSocialID LEFT JOIN ( SELECT * FROM ( SELECT ROW_NUMBER() OVER (PARTITION BY CMSocialID ORDER BY CreateTime DESC) AS group_index ,* FROM CMSocialCheck WHERE IsDelete<>1 ) AS SCsub WHERE SCsub.group_index=1 ) AS SC ON SC.CMSocialID=SM.CMSocialID '; --WHERE S.IsAvailable = 1 print(@strSql); --拼接分页壳子 set @strSql='SELECT A.* FROM ( SELECT ROW_NUMBER() OVER (ORDER BY ASub.CMSocialID DESC) AS RowNumber,* FROM (' + @strSql + ' ) AS ASub ) AS A WHERE RowNumber BETWEEN ' + CAST(((@PageIndex-1)*@PageSize + 1) as nvarchar(20)) + ' AND ' + CAST((@PageIndex*@PageSize) as nvarchar(20)); print(@strSql); exec (@strSql); --获取总记录数 set @strSql='SELECT @Total = COUNT(1) FROM( (SELECT CMSocialID FROM CMSocialMember WHERE MemberID=1 AND IsDelete<>1 AND IsAvailable=1) AS SM INNER JOIN CMSocial AS S ON S.CMSocialID=SM.CMSocialID )'; print(@strSql); EXECUTE sp_executesql @strSql,N'@Total INT OUTPUT',@Total OUTPUT; SET NOCOUNT OFF; END GO
也可以结合存储过程和实物:
USE [TestDB] GO /****** Object: StoredProcedure [dbo].[GetPageDataList] Script Date: 11/16/2017 14:13:46 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author: <Author,,熊学浩> -- Create date: <Create Date,,2017/11/16> -- Description: <Description,,Sql存储过程分页> -- ============================================= CREATE PROC [dbo].[GetPageDataList] ( @TableName varchar(5000), --表名 @Fields varchar(5000) = '*', --字段名(全部字段为*) @OrderField varchar(5000), --排序字段(必须!支持多字段) @OrderType varchar(5000), --排序类型 @sqlWhere varchar(5000) = Null, --条件语句(不用加where) @pageSize int, --每页多少条记录 @pageIndex int = 1 , --指定当前为第几页 @TotalPage int output, --返回总页数 @totalRecord int output --计算总记录数 --返回总记录数 ) AS begin Begin Tran --开始事务 Declare @sql nvarchar(500); if (@SqlWhere='' or @sqlWhere=NULL) set @sql = 'select @totalRecord = count(*) from ' + @TableName else set @sql = 'select @totalRecord = count(*) from ' + @TableName + ' where ' + @sqlWhere EXEC sp_executesql @sql,N'@totalRecord int OUTPUT',@totalRecord OUTPUT--计算总记录数 --计算总页数 select @TotalPage=CEILING((@totalRecord+0.0)/@PageSize) if (@SqlWhere='' or @sqlWhere=NULL) set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField +' ' + @Ordertype+' ) as rowId,' + @Fields + ' from ' + @TableName else set @sql = 'Select * FROM (select ROW_NUMBER() Over(order by ' + @OrderField +' ' + @Ordertype+' ) as rowId,' + @Fields + ' from ' + @TableName + ' where ' + @SqlWhere --处理页数超出范围情况 if @PageIndex<=0 Set @pageIndex = 1 if @pageIndex>@TotalPage Set @pageIndex = @TotalPage --处理开始点和结束点 Declare @StartRecord int Declare @EndRecord int set @StartRecord = (@pageIndex-1)*@PageSize + 1 set @EndRecord = @StartRecord + @pageSize - 1 --继续合成sql语句 set @Sql = @Sql + ') as ' + @TableName + ' where rowid between ' + Convert(varchar(50),@StartRecord) + ' and ' + Convert(varchar(50),@EndRecord) --print @Sql Exec(@Sql) --------------------------------------------------- If @@Error <> 0 Begin RollBack Tran Return -1 End Else Begin Commit Tran Return @totalRecord ---返回记录总数 End end GO
