的MS Access/SQL Server的語法（我猜）

Question

此查詢：

SELECT sentmails.[VersandDatum], 
     sentmails.[DatumMailGeplant], 
     mailintervals.[Interval], 
     definitions.[Subject], 
     users.[Name], 
     sentmails.[MailArt], 
     Objekte.[Name], 
     sentmails.[Erledigt], 
     sentmails.[ID] 
    FROM Objekte 
RIGHT JOIN (users RIGHT JOIN (definitions RIGHT JOIN (mailintervals RIGHT JOIN (sentmails) ON mailintervals.ID=sentmails.Intervall) ON definitions.ID=sentmails.Noti_ID) ON users.UID=sentmails.Funktion) ON Objekte.OId=sentmails.Objekt_ID 

...作品在MS Access QBE罰款，但在SQL Server，它返回一個 「不正確的語法附近 '）'」 的錯誤。我真的想知道爲什麼：

• 連接需要在括號內？
• 沒有更多的外部連接在SQL Server？
• 需要更多括號嗎？

Answer 1

您的JOIN語法不正確。您應該單獨加入每個表格，而無需嵌套括號。你可能想要類似的東西：

SELECT sentmails.[VersandDatum] 
    , sentmails.[DatumMailGeplant] 
    , mailintervals.[Interval] 
    , definitions.[Subject] 
    , users.[Name] 
    , sentmails.[MailArt] 
    , Objekte.[Name] 
    , sentmails.[Erledigt] 
    , sentmails.[ID] 
FROM Objekte 
RIGHT JOIN sentmails ON Objekte.OId = sentmails.Objekt_ID 
RIGHT JOIN users ON users.UID = sentmails.Funktion 
RIGHT JOIN definitions ON definitions.ID = sentmails.Noti_ID 
RIGHT JOIN mailintervals ON mailintervals.ID = sentmails.Intervall 

Here's a starting point in MSDN。

MS Access有一個稍微不同的JOIN語法。使用這個來代替：

SELECT 
    sentmails.[VersandDatum], 
    sentmails.[DatumMailGeplant], 
    mailintervals.[Interval], 
    definitions.[Subject], 
    users.[Name], 
    sentmails.[MailArt], 
    Objekte.[Name], 
    sentmails.[Erledigt], 
    sentmails.[ID] 
FROM Objekte 
RIGHT JOIN sentmails ON Objekte.OId=sentmails.Objekt_ID 
RIGHT JOIN definitions definitions.ID=sentmails.Noti_ID 
RIGHT JOIN mailintervals ON mailintervals.ID=sentmails.Intervall 
RIGHT JOIN users ON users.UID=sentmails.Funktion
