Question

我是SQL的新手......

我正在使用以下三个表：

表：广告系列

Campaign SourcePhone  StartDate  EndDate
A         1112223333  20140303   20140309
B         2223334444  20140303   20140309
C         1112223333  20140310   20140316
D         3334445555  20140217   20150217

表：PhoneMapping（将SourcePhone从广告系列映射到订单表）

SourcePhone TransferToPhone
1112223333  9998887777
1112223333  8887776666
2223334444  7776665555
3334445555  6665554444
3334445555  5554443333

表：订单

Date     TransferToPhone Orders
20140304 9998887777      3
20140304 8887776666      4
20140304 6665554444      34
20140305 7776665555      7
20140305 9998887777      5
20140306 9998887777      10
20140306 8887776666      13
20140307 8887776666      7
20140309 7776665555      1
20140311 9998887777      35
20140313 8887776666      8
20140315 9998887777      22
20140305 6665554444      11

我一直在尝试提出一个将连接这三个表并提供以下结果的查询。基本上，我需要为每个广告系列，SourcePhone＃，转移到电话号码和日期范围（每个广告系列的StartDate和EndDate之间）提供一笔TotalOrders。以下是我期待查询提供的结果（我认为我做了正确的数学运算）。非常感谢任何帮助！

预期结果：

Campaign    SourcePhone TransferToPhone StartDate   EndDate     TotalOrders
A           1112223333  9998887777      20140303    20140309    18
A           1112223333  8887776666      20140303    20140309    24
B           2223334444  7776665555      20140303    20140309    8
C           1112223333  9998887777      20140310    20140316    57
C           1112223333  8887776666      20140310    20140316    8
D           3334445555  6665554444      20140217    20150217    45

以下是我尝试过的内容，但不会根据日期范围对数据进行分组：

SELECT  C.Campaign, C.SourcePhone, PM.TransferToPhone, C.StartDate , C.EndDate, O.TotalOrders
FROM    Campaigns AS C
    INNER JOIN 
         (SELECT SourcePhone, TransferToPhone
           FROM            PhoneMapping
           WHERE        (TransferToPhone IS NOT NULL)) AS PM ON C.SourcePhone = PM.SourcePhone 
           INNER JOIN
             (SELECT        TransferToPhone, SUM(Orders) AS TotalOrders
               FROM            Orders
               WHERE        (Orders IS NOT NULL) 
               Group by TransferToPhone) AS O ON PM.TransferToPhone = O.TransferToPhone

GROUP BY C.Campaign, C.SourcePhone, PM.TransferToPhone, C.StartDate , C.EndDate

这能满足您的需求吗？

SELECT  C.Campaign,
        C.SourcePhone,
        P.TransferToPhone,
        C.StartDate,
        C.EndDate,
        SUM(O.TotalOrders)
FROM Campaigns C
  JOIN PhoneMapping P
    ON C.SourcePhone = P.SourcePhone
  JOIN Orders O
    ON O.TransferToPhone = P.TransferToPhone
GROUP BY C.Campaign, C.StartDate, C.EndDate, P.SourcePhone, P.TransferToPhone

SQL Server;尝试加入三个表，聚合和分组结果
