我無法使該SQL正常工作，有人可以發現它嗎？

Question

SELECT 
    [Stock Conversion Items].SCID, 
    [Stock Conversion Items].[Result PC], 
    [Stock Conversion Items].[Quantity], 
    [Stock Conversion].[Date], 
    [products/stock].[Description] 
FROM 
    [Stock Conversion Items] 
INNER JOIN [Stock Conversion] 
    ON [Stock Conversion Items].SCID = [Stock Conversion].SCID 
INNER JOIN [products/stock] 
    ON [Stock Conversion Items].[Result PC] = [products/stock].[Product Code] 
ORDER BY [Stock Conversion Items].SCID;

這段代碼很容易解釋，基本上我遇到了根本無法解決的語法運算符錯誤。

Answer 1

重新格式化查詢，使其看起來像這樣：

SELECT sci.SCID, sci.[Result PC], sci.Quantity, sci.Date, s.Description
FROM [Stock Conversion Items] sci
INNER JOIN [Stock Conversion] sc 
   ON sci.SCID = sc.SCID 
INNER JOIN [products/stock] s 
   ON sci.[Result PC] = s.[Product Code] 
ORDER BY sci.SCID;

在該語句中唯一可能失敗的是on子句。 您確定兩個SCID列以及[Result PC]和[Product Code]列都屬於同一類型嗎？

Answer 2

由於某種原因，Access似乎想在第一個聯接周圍加上括號。 這似乎可行：

SELECT [Stock Conversion Items].SCID, [Stock Conversion Items].[Result PC], [Stock Conversion Items].Quantity, [Stock Conversion].Date, [products/stock].Description
FROM ([Stock Conversion] INNER JOIN [Stock Conversion Items] ON [Stock Conversion].SCID = [Stock Conversion Items].SCID) INNER JOIN [products/stock] ON [Stock Conversion Items].[Result PC] = [products/stock].[Product Code];

Answer 3

        SELECT [Stock Conversion Items].SCID,
     [Stock Conversion Items].[Result PC],
     [Stock Conversion Items].Quantity,
     [products/stock].Description,
     [Stock Conversion].[SC Date],
     [Stock Conversion].[Created By]

     FROM [Stock Conversion Items]
      INNER JOIN ([products/stock] INNER JOIN [Stock Conversion]
        ON [products/stock].[Product Code] = [Stock Conversion].[Source PC])
        ON [Stock Conversion Items].SCID = [Stock Conversion].SCID;

因此，這就是Access提出的解決我的問題的方法，設法使事情正常運行，認為可能是數據類型不匹配。 所以，謝謝Sweko。
