连接3个表-MySQL

我有三张桌子：

主题：

ID_subject    Subject_name

问题:

ID_question   Question   ID_subject

答复

ID_answer     Answer     ID_question

---

是否可以选择结果将是第三个主题的所有答案？我试图进行双重连接，但没有成功，它返回了我所有的答案

这将返回您要查找的结果：

SELECT a.ID_answer, a.Answer FROM Answers a 
JOIN Questions q ON q.ID_question = a.ID_question
JOIN Subjects s ON s.ID_subject = q.ID_subject
WHERE s.ID_subject = ID_of_third_subject
