<select id="findEventDetailInfo" resultMap="BaseResultMap" parameterType="Java.lang.Long"> SELECT <include refid="Base_Column_List"/>,1 as businessType1,2 as businessType2 FROM evt_t_event e where e.id = #{id,jdbcType=BIGINT} AND e.db_status = 1 </select>
总结
以上为个人经验,希望能给大家一个参考,也希望大家多多支持编程客栈(www.cppcnsYusnhZz.com)。
