代码中涉及的sql语句

<select id="selectLastQuestionId" resultType="int">
 select max(id) from sys_question
 </select>

 <select id="selectAllQuestion" resultMap="BaseResultMap">
 select * from sys_question order by create_time desc
</select>

<select id="selectByQuestionId" resultMap="BaseResultMap">
 select * from sys_question_answer
 where question_id=#{question_id}
 </select>

 <select id="selectLastAnswerId" resultType="int">
 select max(id) from sys_question_answer
 </select>

 <delete id="deleteByQUestionId">
 delete from sys_question_answer where question_id=#{question_id}
</delete>
