SQL：語法錯誤（缺少運算符）

Question

我不是那種善於SQL在所有

我有一個MS Access數據庫的兩個表

|ID| Name |Surname|Postion|   |EmpID|ManID| 
----------------------------   ------------- 
|1 |Scrooge|McDuck |Manager|   |3 |1 | 
|2 |Daisy |Duck |Manager|   |7 |1 | 
|3 |Donald |Duck |Support|   |6 |2 | 
|4 |Minny |Mouse |Support|   |4 |2 | 
|5 |Mickey |Mouse |Support|   |2 |1 | 
|6 |Goofy |  |Support|   |1 |2 | 
|7 |Pluto |  |Support|   |5 |2 | 
|8 |Huey |Duck |Support| 
|9 |Dewey |Duck |Support| 
|10|Louie |Duck |Support| 

我需要編寫SQL語句產生下面的輸出

| Name |Surname|Postion|Manager Name|Manager Positon|   
------------------------    
|Donald |Duck |Support|Scrooge  |Manager   
|Pluto |  |Support|Scrooge  |Manager   
|Goofy |  |Support|Daisy  |Manager   
|Minny |Mouse |Support|Daisy  |Manager  
|Daisy |Duck |Support|Scrooge  |Manager   
|Scrooge|McDuck |Manager|Daisy  |Manager   
|Mickey |Mouse |Manager|Daisy  |Manager 

我的代碼看起來是這樣的，到目前爲止（我一直在尋找的淨，看看它是如何做和爲什麼）

SELECT Employee.Name,Employee.Surname,Employee.Position,Manager.Name as ManagerName 
FROM Employee 
INNER JOIN Stafflink ON Employee.ID=Stafflink.EmpID 
INNER JOIN Employee Manager ON Manager.ID=Stafflink.ManID; 

我知道這個問題是回答Sql table output

，但它似乎不工作，並生成錯誤：

Syntax error (Missing operator)

任何援助將不勝感激。

MS Access有多個JOIN秒的非典型的要求，他們被封閉在嵌套()團體，如：

FROM 
    ((t1 INNER JOIN t2 ON t1.id = t2.id) 
    INNER JOIN t3 ON t2.id = t3.id) 

你FROM條款應該表示爲：

SELECT Employee.Name,Employee.Surname,Employee.Position,Manager.Name as ManagerName 
FROM ((
    Employee 
    INNER JOIN Stafflink ON Employee.ID=Stafflink.EmpID) 
    INNER JOIN Employee Manager ON Manager.ID=Stafflink.ManID);
