帶有左連接，Where子句和Sum（）的SQL語句？

Question

我真的在努力處理下面的SQL。我嘗試了很多不同的東西，而且我無法讓他們工作。

我基本上需要做的是LEFT OUTER JOIN這個工作的SQL語句：

SELECT "TABLE1"."Sheet Number", 
     "TABLE1"."ID Number", 
     "TABLE1"."Identification", 
     "TABLE1"."Job Date", 
     "TABLE1"."p2c", 
     "TABLE2"."Range", 
     "TABLE1"."bcr", 
     "TABLE1"."Dataset ID", 
     "TABLE1"."ACC", 
     "TABLE1"."GNC", 
     "TABLE1"."Year", 
     "TABLE1"."Period", 
     "TABLE1"."Week", 
     "TABLE1"."Job_ID" 
FROM  "DATABASE"."dbo"."TABLE2" "TABLE2" LEFT OUTER JOIN "DATABASE"."dbo"."TABLE1" "TABLE1" 
     ON (((("TABLE2"."Contract"="TABLE1"."GNC") 
     AND ("TABLE2"."FromPeriod"="TABLE1"."Period")) 
     AND ("TABLE2"."FromWeek"="TABLE1"."Week")) 
     AND ("TABLE2"."FromYear"="TABLE1"."Year")) 
WHERE "TABLE1"."ACC"='ACCOUNT57' 
     AND "TABLE1"."Dataset ID"=5 
     AND "TABLE1"."bcr"=1 
     AND "TABLE2"."Range"='Week' 
ORDER BY "TABLE1"."Sheet Number" 

這一個：

SELECT "SALES"."JobId", 
     "SALES"."Total", 
     SUM("SALES"."Total") AS JOBTOTAL 
FROM "DATABASE"."dbo"."SALES" "SALES" 
GROUP BY "SALES"."JobId" 
ON "SALES"."JobId"="TABLE1"."Job_ID" 

但是其他的聯接是造成我困惑的一個很大的/嘗試實施我在網上找到的解決方案時感到沮喪。我讀過它可能是WHERE和GROUP BY語句不是很好玩？

但我似乎無法得到任何解決方案，我發現在線工作。我試過的一個解決方案看起來像是用括號內的SUM（）和GROUP BY（我的底部語句）包裝了SQL語句並加入了它？

有人能幫忙嗎？

謝謝你的時間。

SELECT 
    t1.Sheet Number, 
    t1.ID Number, 
    t1.Identification, 
    t1."Job Date", 
    t1.p2c, 
    t1."Range", 
    t1.bcr, 
    t1.Dataset ID, 
    t1.ACC, 
    t1.GNC, 
    t1."Year", 
    t1.Period, 
    t1."Week", 
    t1.Job_ID, 
    SUM(s.Total) AS JOBTOTAL 
FROM  
    dbo.TABLE1 t1 
    LEFT JOIN dbo.Sales s 
     ON t.Job_Id = s.Job_id 
WHERE 
    t1.ACC='ACCOUNT57' 
    AND t1.Dataset ID=5 
    AND t1.bcr=1 
    AND EXISTS (SELECT * 
      FROM 
       dbo.TABLE2 t2 
      WHERE 
       t1.GNC = t2.Contract 
       AND t1.Period = t2.FromPeriod 
       AND t1."Week" = t2.FromWeek 
       AND t1."Year" = t2.FromYear 
       AND t2."Range"='Week') 
GROUP BY 
    t1.Sheet Number, 
    t1.ID Number, 
    t1.Identification, 
    t1."Job Date", 
    t1.p2c, 
    t1."Range", 
    t1.bcr, 
    t1.Dataset ID, 
    t1.ACC, 
    t1.GNC, 
    t1."Year", 
    t1.Period, 
    t1."Week", 
    t1.Job_ID 
ORDER BY 
    t1.Sheet Number 

你也可以這樣來做：

SELECT DISTINCT 
    t1.Sheet Number, 
    t1.ID Number, 
    t1.Identification, 
    t1."Job Date", 
    t1.p2c, 
    t1."Range", 
    t1.bcr, 
    t1.Dataset ID, 
    t1.ACC, 
    t1.GNC, 
    t1."Year", 
    t1.Period, 
    t1."Week", 
    t1.Job_ID, 
    s.JOBTOTAL 
FROM  
    dbo.TABLE1 t1 

    INNER JOIN dbo.TABLE2 t2 
    ON t1.GNC = t2.Contract 
    AND t1.Period = t2.FromPeriod 
    AND t1."Week" = t2.FromWeek 
    AND t1."Year" = t2.FromYear 
    AND t2."Range"='Week' 

    LEFT JOIN (SELECT 
       SUM(s.Total) AS JOBTOTAL 
      FROM 
       dbo.Sales s 
      WHERE 
       t.Job_Id = s.Job_id) s 
WHERE 
    t1.ACC='ACCOUNT57' 
    AND t1.Dataset ID=5 
    AND t1.bcr=1 
ORDER BY 
    t1.Sheet Number
