Question

在一个月内，按AccountNo分开，必须输出3天内超过10,000金额的所有交易。

这是一个示例表：

AccountNo-----Date------------Amount
1-------------5/1/17----------8000
1-------------5/3/17----------1000
1-------------5/4/17----------1000
1-------------5/6/17----------1000
2-------------5/7/17----------3000
2-------------5/10/17---------2000
2-------------5/13/17---------2000
2-------------5/13/17---------3000
3-------------5/14/17---------3000
3-------------5/15/17---------3000
3-------------5/16/17---------9000
4-------------5/17/17---------1000
5-------------5/18/17---------1000
5-------------5/19/17---------1000
5-------------5/20/17---------1000

结果必须是：

AccountNo-----Date------------Amount
1-------------5/1/17----------8000
1-------------5/3/17----------1000
1-------------5/4/17----------1000
2-------------5/7/17----------3000
2-------------5/10/17---------2000
2-------------5/13/17---------2000
2-------------5/13/17---------3000
3-------------5/14/17---------3000
3-------------5/15/17---------3000
3-------------5/16/17---------9000

有一个代码给我，但它还没有完全正常工作。

Select A.*
 From  YourTable A
 Cross Apply (
            Select RT1 = sum(case when [Date] <= B2.TstDate then [Amount] else 0 end)
                  ,RT2 = sum(case when [Date] >= B2.TstDate then [Amount] else 0 end)
         From  YourTable B1
         Cross Join (Select TstDate=A.[Date]) B2
         Where [Date] between DateAdd(DAY,-2,A.[Date]) and DateAdd(DAY,2,A.[Date])
           and Year([Date])=Year(TstDate)
           and Month([Date])=Month(TstDate)
     ) B
 Where RT1>=10000 or RT2>=10000

Answer 1

公用表表达式：TransInfo

TransInfo是一个包含帐户，年，月，日，金额的表

主要查询：

[Tmiddle]查询根据每个帐号每月每天的金额添加一个row_number
[Tmiddle]再次与TransInfo合并，将结果限制为一个月的前3个AS [Touter]，其中前3名> = 10.000
最外面的查询再次将结果与表格相结合，以再次获得完整的交易信息

简而言之：

按每个帐户每年每月最多3笔金额过滤数据
检查金额总和＆gt; = 10.000
显示结果

查询：

WITH [TransInfo] ([AccountNo], [Year], [Month], [Day], [Amount], [Rownumber])
AS
(
    SELECT [AccountNo]
          ,[Year]
          ,[Month]
          ,[Day]
          ,[Amount]
          ,ROW_NUMBER() OVER 
          (
              PARTITION BY [AccountNo], 
              [Year],
              [Month] 
              ORDER BY [Amount] DESC
          ) AS [Rownumber]
    FROM
    (
        SELECT [AccountNo]
                ,DATEPART(YEAR, [Date]) AS [Year]
                ,DATEPART(MONTH, [Date]) AS [Month]
                ,DATEPART(DAY, [Date]) AS [Day]
                ,SUM([Amount]) AS [Amount]
        FROM [Test].[dbo].[Data]
        GROUP BY [AccountNo], 
                    DATEPART(MONTH, [Date]), 
                    DATEPART(YEAR, [Date]),
                    DATEPART(DAY, [Date])
    ) AS [Tinner]
)
SELECT [Data].[AccountNo]
      ,[Data].[Date]
      ,[Data].[Amount]
FROM [Test].[dbo].[Data]
INNER JOIN
(
    SELECT [TransInfo].[AccountNo]
          ,[TransInfo].[Year]
          ,[TransInfo].[Month]
          ,[TransInfo].[Day]
          ,[TransInfo].[Amount]
    FROM [TransInfo]
    INNER JOIN
    (
        SELECT [AccountNo]
              ,[Year]
              ,[Month]
        FROM [TransInfo] 
        WHERE [TransInfo].[Rownumber] <= 3
        GROUP BY [TransInfo].[AccountNo], 
                 [TransInfo].[Year],
                 [TransInfo].[Month]
        HAVING SUM ([TransInfo].[Amount]) >= 10000
    ) AS [Tmiddle]
    ON [Tmiddle].[AccountNo] = [TransInfo].[AccountNo]
    AND [Tmiddle].[Year] = [TransInfo].[Year]
    AND [Tmiddle].[Month] = [TransInfo].[Month]
    WHERE [TransInfo].[Rownumber] <= 3
) AS [Touter]
ON [Data].[AccountNo] = [TOuter].[AccountNo]
AND DATEPART(YEAR, [Data].[Date]) = [TOuter].[Year]
AND DATEPART(MONTH, [Data].[Date]) = [TOuter].[Month]
AND DATEPART(DAY, [Data].[Date]) = [TOuter].[Day]

结果：左边是查询结果，右边是完整表

Answer 2

这是否按预期工作？ 根据“3天内”的含义，您可能需要将2更改为3。

SELECT DISTINCT C.*
FROM YourTable C
INNER JOIN (
SELECT a.AccountNo, a.Date
FROM YourTable a
INNER JOIN YourTable b
ON a.AccountNo = b.AccountNo
AND DATEADD(DAY, 2, a.Date) <= b.Date AND b.Date >= a.Date
GROUP BY a.AccountNo, a.Date 
HAVING SUM(b.Amount) > 10000
) d
ON C.AccountNo = d.AccountNo
AND DATEADD(DAY, 2, D.Date) <= C.Date AND C.Date >= D.Date

在3天内输出超过一定金额的交易
