左聯接兩個表，然后僅將新行追加到表

Question

我試圖從tblForecast中獲取所有記錄，並從tblOpenJobs中獲取匹配記錄，並將它們追加到tblWorkingTable中，但前提是[tbWorkingTable中尚不存在[Job＃]。

第一部分（通過第一個左連接）工作正常，但是第二個左連接和Where語句失敗，出現語法錯誤：

查詢表達式'A. [Job＃] = B. [Job＃] LEFT JOIN tblWorkingTable AS C ON A. [Job＃] = C. [Job＃“中的語法錯誤（缺少運算符）。

我對SQL還是很陌生，所以我不確定我哪里出錯了。 我可能可以使它與兩個獨立的查詢一起工作，但是將其全部工作於一個中確實是理想的。

INSERT INTO tblWorkingTable ( [Rec'd], ForecastMonth, [Ship Week], [Commit Date], [Job #], Customer, [Part #], Released, [Forecast Qty], [Actual Qty], Shipped, [Sales Price], [Sales Value], Invoice, Comments )
SELECT B.[Rec'd], A.ForecastMonth, A.[Ship Week], A.[Commit Date], A.[Job #], A.Customer, A.[Part #], B.Released, A.Qty AS [Forecast Qty], B.Qty AS [Actual Qty], B.Shipped, A.[Sales Price], A.[Sales Value], A.Invoice, A.Comments
FROM tblForecast AS A 
LEFT JOIN tblOpenJobs AS B ON A.[Job #] = B.[Job #]
LEFT JOIN tblWorkingTable AS C ON A.[Job #] = C.[Job #]
Where ((C.[Job #]) is Null);

是的，我知道，這些字段名稱中不應包含特殊字符。 在數據導入期間，我需要為這些名稱分配其他名稱。

MS Access需要在連接周圍加上括號。 嘗試這個：

INSERT INTO tblWorkingTable ( [Rec'd], ForecastMonth, [Ship Week], [Commit Date], [Job #], Customer, [Part #], Released, [Forecast Qty], [Actual Qty], Shipped, [Sales Price], [Sales Value], Invoice, Comments )
    SELECT B.[Rec'd], A.ForecastMonth, A.[Ship Week], A.[Commit Date], A.[Job #], A.Customer, A.[Part #], B.Released, A.Qty AS [Forecast Qty],
           B.Qty AS [Actual Qty], B.Shipped, A.[Sales Price], A.[Sales Value], A.Invoice, A.Comments
    FROM (tblForecast AS A LEFT JOIN
          tblOpenJobs AS B
          ON A.[Job #] = B.[Job #] 
         ) LEFT JOIN
         tblWorkingTable AS C
         ON A.[Job #] = C.[Job #]
    WHERE C.[Job #] is Null;
