ms access / sql server 语法（我猜）

此查询：

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

...在 ms access qbe 中工作正常，但在 sql server 中它返回“')'附近的语法不正确”错误。我真的很想知道为什么：

连接需要放在括号中？
sql server 中不再有外连接了吗？
哪里需要更多括号？

this query:

       mailintervals.[Interval],

       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

...works fine in ms access qbe, but in sql server it returns a "incorrect syntax near ')'" error. I'm really wondering why:

the joins need to be in brackets?
no more outer joins in sql server?
somewhere more brackets needed?

MS Access 的 JOIN 语法略有不同。使用这个代替：

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

MS Access has a slightly different JOIN syntax. Use this instead:

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

您的 JOIN 语法不正确。您应该单独连接每个表，而不使用嵌套括号。您可能想要类似的内容：

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

这是 MSDN 中的起点。

Your JOIN syntax is incorrect. You should be joining each table individually, without nested parentheses. You probably want something like:

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.
