springdata的Query注解写的sql一直报错(Encountered ?400报错

SELECT Q.qid,Q.userid,Q.content,Q.nickname,Q.rid,Q.create_time,R.id,R.content,R.lawyername FROM client_question AS Q JOIN client_reply AS R WHERE Q.rid =  R.id AND Q.qid = ''

这是SQL 其中有两张表的一个字段相同,语句在sqlyong运行没有问题

但是在Jpa里面

    @Query(nativeQuery = true,
            value = "SELECT Q.qid,Q.userid,Q.content,Q.nickname,Q.rid,Q.create_time,R.id,R.content,R.lawyername FROM client_question AS Q JOIN client_reply AS R WHERE Q.rid =  R.id AND Q.qid = :Qid")
    List<Map<String,Object>> findByQid(@Param("Qid")String Qid);

报错如下
