MySQL查询的方式非常多，以下为您介绍的MySQL查询实现的是查询本周、上周、本月、上个月份的数据，假设您对MySQL查询方面感兴趣的话，***还是一看

查询当前这周的数据 

SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now()); 

查询上周的数据 
SELECT name,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime,'%Y-%m-%d')) = YEARWEEK(now())-1; 

查询当前月份的数据 
select name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(now(),'%Y-%m') 

查询距离当前如今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 name,submittime from enterprise where date_format(submittime,'%Y-%m')=date_format(DATE_SUB(curdate(), INTERVAL 1 MONTH),'%Y-%m') 

select * from `user` where DATE_FORMAT(pudate,'%Y%m') = DATE_FORMAT(CURDATE(),'%Y%m') ; 

select * from user where WEEKOFYEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = WEEKOFYEAR(now()) 

select * 
from user 
where MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()) 

select * 
from [user] 
where YEAR(FROM_UNIXTIME(pudate,'%y-%m-%d')) = YEAR(now()) 
and MONTH(FROM_UNIXTIME(pudate,'%y-%m-%d')) = MONTH(now()) 

select * 
from [user] 
where pudate between 上月最后一天 
and 下月第一天

今天
select * from 表名 where to_days(时间字段) = to_days(now());
昨天
select * from 表名 where to_days(now())-to_days(时间字段) = 1;
近7天
select * from 表名 where date_sub(curdate(), interval 7 day) <= date(时间字段);
