        <result column="commit_status" property="commitStatus" />

    </resultMap>

    <select id="selectHomeworkByTeacherUserId" resultMap="BaseResultMap">
        SELECT
            d.dmmx_mc,h.id,h.title,h.content,h.modify_time
        FROM
            `base_dmmx` d JOIN homework h ON d.dmmx_code=h.subject_code
        WHERE
            d.dm_code = 'DM_ZXXKC' AND h.semester_id=3 AND h.create_person=13
        ORDER BY h.modify_time DESC
    </select>
