查询距离当前现在6个月的数据
select name,submittime from enterprise where submittime between date_sub(now(),interval 6 month) and now();
查询上个月的数据

SELECT DATE_ADD(DATE_FORMAT(now(),'%Y-%m-%d'),INTERVAL 0-DAYOFWEEK(now()) day);-- 上周最后一天
SELECT DATE_ADD(DATE_FORMAT(now(),'%Y-%m-%d'),INTERVAL 0-DAYOFMONTH(now()) day);-- 上周最后一天
