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
GOSET QUOTED_IDENTIFIER ON
GOCREATE 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 DwhereWHERE rownum BETWEEN ' + CAST(((@PageIndex-1)*@PageSize + 1) as nvarchar(20)) + ' and ' + cast((@PageIndex*@PageSize) as nvarchar(20))exec (@strSql)--print @strSqlset @strSql='SELECT @Total = COUNT(0) FROM ' + @tab + ' WHERE 1=1 ' + @strWhere --print @strSqlEXECUTE sp_executesql @strSql,N'@Total INT OUTPUT',@Total OUTPUTset 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
GOSET QUOTED_IDENTIFIER ON
GO-- =============================================

AS

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.IsRecommendFROM (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 = 1print(@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 AWHERE 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;
ENDGO

也可以结合存储过程和实物：
