数据库中的格式如下，，是个记录明细表，要求对明细表进行按日汇总倒序输出。
用下面的SQL语句可以进行按日汇总并且可以分页输出
DECLARE @Days TABLE(日期 DATETIME)DECLARE @StartDate datetime='2014-04-05 14:22:20'–汇总的开始日期DECLARE @EndDate datetime='2015-04-08 15:21:33'–汇总的结束日期DECLARE @start DATETIMEDECLARE @E2_UserName varchar(100)='CN000001'–用户名DECLARE @StartID INT=1–分页使用的获取记录的开始IDDECLARE @EndID INT =15–分页使用的获取记录的结束ID,测试为15条数据SET @start = CONVERT(VARCHAR, @StartDate, 23 )+' 00:00:00'WHILE @start <= CONVERT(VARCHAR, @EndDate, 23 )+' 00:00:00'BEGININSERT INTO @Days VALUES(@start)SET @start = DATEADD(DAY, 1, @start)END;WITH orderList AS (SELECT ROW_NUMBER() OVER (ORDER BY 日期 DESC)AS Row,–这里规定了是按日期倒序排列SUM(MD_TuiJianJiang) AS 'MD_TuiJianJiang',SUM(MD_JianDianJiang) AS 'MD_JianDianJiang',SUM(MD_RiFenHong) AS 'MD_RiFenHong',SUM(MD_JiHuo) AS 'MD_JiHuo',SUM(MD_TGZXJiang) AS 'MD_TGZXJiang',SUM(MD_LingDaoJiang) AS 'MD_LingDaoJiang',SUM(MD_ShiChangJiang) AS 'MD_ShiChangJiang',SUM(MD_Help) AS 'MD_Help',SUM(MD_Luckly) AS 'MD_Luckly',SUM(MD_FanBuJiang) AS 'MD_FanBuJiang',SUM(MD_Month) AS 'MD_Month',SUM(MD_CheckIN) AS 'MD_CheckIN',SUM(TOTAL) AS 'TOTAL',日期 FROM (SELECTSUM(ISNULL([MD_TuiJianJiang],0)) AS 'MD_TuiJianJiang',SUM(ISNULL([MD_JianDianJiang],0)) AS 'MD_JianDianJiang',SUM(ISNULL([MD_RiFenHong],0)) AS 'MD_RiFenHong',SUM(ISNULL([MD_JiHuo],0)) AS 'MD_JiHuo',SUM(ISNULL([MD_TGZXJiang],0)) AS 'MD_TGZXJiang',SUM(ISNULL([MD_LingDaoJiang],0)) AS 'MD_LingDaoJiang',SUM(ISNULL([MD_ShiChangJiang],0)) AS 'MD_ShiChangJiang',SUM(ISNULL([MD_Help],0)) AS 'MD_Help',SUM(ISNULL([MD_Luckly],0)) AS 'MD_Luckly',SUM(ISNULL([MD_FanBuJiang],0)) AS 'MD_FanBuJiang',SUM(ISNULL([MD_Month],0)) AS 'MD_Month',SUM(ISNULL([MD_CheckIN],0)) AS 'MD_CheckIN',SUM(ISNULL(MD_TuiJianJiang+MD_RiFenHong+MD_JianDianJiang+MD_JiHuo,0)) AS 'TOTAL',–ISNULL(DAY(MD_Datetime),DAY(B.日期)) AS 'MD_Datetime',ISNULL([E2_UserName],@E2_UserName) AS 'E2_UserName',B.日期FROM [E2_MoneyDetails]RIGHT JOIN @Days B ON CONVERT(VARCHAR, MD_Datetime, 23 )+' 00:00:00'=B.日期 AND [E2_UserName]=@E2_UserNameWHERE B.日期 BETWEEN DATEADD(DAY, -1, @StartDate) AND @EndDateGROUP BY B.日期,E2_UserName) EGROUP BY 日期)SELECT *FROM orderlistWHERE Row BETWEEN @StartID AND @EndID
最终的结果样式为
有时不但是必要的，而且是很有必要的。
