我需要帮助。我有两个用户帐户，一个是学生帐户，另一个是专家帐户。学生帐户页面发送一个经过解析并存储在数据库中的问题。然后将此问题转发给专家帐户以查看并回答。来自专家的答案随后存储在数据库中，然后转发到学生账户以获得结果。
我的问题是这个。我有一个结果页面，一旦学生输入完他/她的问题并将其发送到数据库，就会出现该页面。此结果页面显示学生输入的问题和系统的答案。
我不知道如何显示答案。我把每件事都建立在我的行号基础上。发送到数据库的问题转到tbl_questions，答案转到tbl_answers。我有另一个名为tbl_link_qa的表，它通过行号将tbl_questions和tbl_answers连接起来。问题显示为与问题相关的答案。
有人能帮我吗？
难道不应该简单地说：
select <relevant fields> from tbl_link_qa qa
inner join tbl_answers a on a.answer_id = qa.answer_id
where qa.question_id = :questionId
