插入语句

        insert into arc_rule_info(tb_nid,tb_name,detail,state,req_ext,add_time )values(#{tbNid,jdbcType=VARCHAR},#{tbName,jdbcType=VARCHAR},#{detail,jdbcType=VARCHAR},#{state,jdbcType=VARCHAR},#{reqExt,jdbcType=VARCHAR}, #{addTime,jdbcType=TIMESTAMP})
    

修改语句

  
        update arc_rule_info set

删除语句

  <delete id="delInfoById"  parameterType="java.util.HashMap">
        delete   from arc_rule_info  where id = #{id,jdbcType=BIGINT}
    delete>
