sql-server - SUM 和 JOIN 显示在一条记录中

Question

我有三个表:Table1 (AF)、Table2 (MC) 和 Table3 (SC)

我目前对这些表有一个查询，如下所示:

SELECT
AF.[Product Number],
AF.[Week End Date],
AF.[Inv Change Cost],
AF.[Gross Sales Lbs],
AF.[Production Lbs],
MC.[Actual Usage Cost] AS MeatCost,
SC.[Actual Usage Cost] AS SeasonCost
FROM Table1 AF
FULL JOIN Table2 MC ON MC.[Product Number] = AF.[Product Number] AND MC.[Week Ending Date] = AF.[Week End Date]
FULL JOIN Table3 SC ON SC.[Product Number] = AF.[Product Number] AND SC.[Week Ending Date] = MC.[Week Ending Date]
WHERE
AF.[Product Number] = '96443' AND
AF.[Week End Date] = '2/4/2017' AND
MC.[Rout Line Name] = 'Total Cost' AND
SC.[Rout Line Name] = 'Total Cost'

返回以下内容:

Prod # | WE Date | IC Cost | Gross Sales | Prod Lbs | Meat Cost | Season Cost |
96443    2/4/2017  -123456   1000           2000       5000        10000
96443    2/4/2017  -123456   1000           2000       5000        20000
96443    2/4/2017  -123456   1000           2000       6000        10000
96443    2/4/2017  -123456   1000           2000       6000        20000

但是，我希望能够对肉类和季节进行求和，以便表格如下所示:

Prod # | WE Date | IC Cost | Gross Sales | Prod Lbs | Meat Cost | Season Cost |
96443    2/4/2017  -123456    1000          2000      11000       30000

我已经尝试了以下语句，但我得到了所有四个记录的两个总和的总和，这不是我想要返回的值:

SELECT
AF.[Product Number],
AF.[Week End Date],
AF.[Inv Change Cost],
AF.[Gross Sales Lbs],
AF.[Production Lbs],
SUM(MC.[Actual Usage Cost]) AS MeatCost,
SUM(SC.[Actual Usage Cost]) AS SeasonCost
FROM Table1 AF
JOIN Table2 MC ON MC.[Product Number] = AF.[Product Number] AND MC.[Week Ending Date] = AF.[Week End Date]
JOIN Table3 SC ON SC.[Product Number] = AF.[Product Number] AND SC.[Week Ending Date] = MC.[Week Ending Date]
WHERE
AF.[Product Number] = '96443' AND
AF.[Week End Date] = '2/4/2017' AND
MC.[Rout Line Name] = 'Total Cost' AND
SC.[Rout Line Name] = 'Total Cost'
GROUP BY
AF.[Product Number],
AF.[Week End Date],
AF.[Inv Change Cost],
AF.[Gross Sales Lbs],
AF.[Production Lbs];

返回结果:

Prod # | WE Date | IC Cost | Gross Sales | Prod Lbs | Meat Cost | Season Cost |
96443    2/4/2017  -123456   1000          2000       22000       60000

我是否需要对所有字段求和才能获得所需的结果？

更新:

我尝试过这个声明:

SELECT
AF.[Product Number],
AF.[Week End Date],
AF.[Inv Change Cost],
AF.[Gross Sales Lbs],
AF.[Production Lbs],
MC.MeatCost,
SC.SeasonCost
FROM Table1 AF
    JOIN(
        SELECT [Product Number], [Week Ending Date], SUM([Actual Usage Cost]) AS MeatCost
        FROM Table2
        GROUP BY [Product Number], [Week Ending Date]
        )MC ON
        AF.[Product Number] = MC.[Product Number] AND
        AF.[Week End Date] = MC.[Week Ending Date]
    JOIN(
        SELECT [Product Number], [Week Ending Date], SUM([Actual Usage Cost]) AS SeasonCost
        FROM Table3
        GROUP BY [Product Number], [Week Ending Date]
        )SC ON
        SC.[Product Number] = MC.[Product Number] AND
        SC.[Week Ending Date] = MC.[Week Ending Date]
WHERE
AF.[Product Number] = '96443' AND
AF.[Week End Date] = '2/4/2017';

但是，我得到了与之前尝试相同的结果。

使用这个例子并尝试这样的事情......

CREATE TABLE #Table1 (id INT IDENTITY(1,1), ProdNum INT, WeekEndDate DATETIME, InvChangeCost NUMERIC(18,2), GrossSales NUMERIC(18,2), ProductionLibs NUMERIC(18,2))

INSERT INTO #Table1( ProdNum ,WeekEndDate ,InvChangeCost ,GrossSales ,ProductionLibs)
VALUES(96443,    '2/4/2017',  -123456,   1000,           2000)

CREATE TABLE #Table2 (id INT IDENTITY(1,1), ProdNum INT, WeekEndDate DATETIME, MeatCost NUMERIC(18,2))

INSERT INTO #Table2( ProdNum ,WeekEndDate ,MeatCost)
VALUES(96443,    '2/4/2017',  5000)
INSERT INTO #Table2( ProdNum ,WeekEndDate ,MeatCost)
VALUES(96443,    '2/4/2017',  6000)

CREATE TABLE #Table3 (id INT IDENTITY(1,1), ProdNum INT, WeekEndDate DATETIME, SeasonCost NUMERIC(18,2))

INSERT INTO #Table3( ProdNum ,WeekEndDate ,SeasonCost)
VALUES(96443,    '2/4/2017',  1000)
INSERT INTO #Table3( ProdNum ,WeekEndDate ,SeasonCost)
VALUES(96443,    '2/4/2017',  2000)

SELECT t1.*
        , t2.MeatCost
        , t3.SeasonCost
FROM #Table1 t1
    JOIN (
            SELECT ProdNum, WeekEndDate, SUM(MeatCost) AS MeatCost
            FROM #Table2 
            GROUP BY ProdNum, WeekEndDate
         )t2 ON
        t1.ProdNum = t2.ProdNum AND
        t1.WeekEndDate = t2.WeekEndDate
    JOIN (
            SELECT ProdNum, WeekEndDate, SUM(SeasonCost) AS SeasonCost
            FROM #Table3 
            GROUP BY ProdNum, WeekEndDate
         )t3 ON
        t3.ProdNum = t2.ProdNum AND
        t3.WeekEndDate = t2.WeekEndDate


DROP TABLE #Table1  
DROP TABLE #Table2
DROP TABLE #Table3
