推荐答案

你试过括号吗？ MS Access需要（即喜欢）多个JOINS周围的括号：

Have you tried it with parentheses? MS Access requires (i.e. likes) parentheses around multiple JOINS:

 SELECT     Task_Id,
            e2.emploeey_name AS W_FROM,
            e1.emploeey_name AS W_TO,
            t.Task_Details
 FROM       
 (
      tasks AS T
      INNER JOIN Employees AS e1 
           ON e1.Emploeey_id = T.Task_To
 )
 INNER JOIN Employees AS e2 
      ON e2.Emploeey_id = T.write_From
