Hibernate的HQL加入了連接表

Question

我想創建HQL查詢，那就是：

 query = "SELECT test From Result result " + 
        "JOIN result.test test JOIN result.user user " + 
        "WHERE test.id = :testId AND user.id = :userId " + 
        "AND result.permission.id = :permissionId"), 

，現在我想添加額外的問題（多對一與測試）和答案（多對一與問題）。如果我嘗試這樣的事情：

 query = "SELECT test From Result result " + 
        "JOIN result.test test JOIN result.user user JOIN test.questions as question" + 
        "WHERE test.id = :testId AND user.id = :userId " + 
        "AND result.permission.id = :permissionId") 

我得到一個exeption。

這裏有一個錯誤（需要有一個空格）

我不知道爲什麼你需要對問題進行加入...你不要在這裏使用它。
