查询本季度数据

?

1	select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(now());

查询上季度数据

?

1	select * from `ht_invoice_information` where QUARTER(create_date)=QUARTER(DATE_SUB(now(),interval 1 QUARTER));

查询本年数据

?

1	select * from `ht_invoice_information` where YEAR (create_date)= YEAR (NOW());

查询上年数据

?

1	select * from `ht_invoice_information` where year (create_date)= year (date_sub(now(),interval 1 year ));

查询当前这周的数据

?

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

查询上周的数据

?

1	SELECT name ,submittime FROM enterprise WHERE YEARWEEK(date_format(submittime, '%Y-%m-%d' )) = YEARWEEK(now())-1;

查询上个月的数据

?

1 2 3 4 5 6

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

查询当前月份的数据

?

1	select name ,submittime from enterprise  where date_format(submittime, '%Y-%m' )=date_format(now(), '%Y-%m' )

查询距离当前现在6个月的数据

?

1	select name ,submittime from enterprise where submittime between date_sub(now(),interval 6 month ) and now();

PS:下面看下mysql如何查询当天信息？

原来不是太熟悉SQL查询语句，什么都是用到了再去查去找，还好网络提供给我们很多支持。今天又用到了一个语句，一时间真想不出怎么解决，到网上看了看，感觉就有一个，怎么那么简单啊。需要积累的东西真是太多了。

今天就把我这个简单的问题记录下来吧!算是一个积累：

mysql查询当天的所有信息：

?

1	select * from test where year (regdate)= year (now()) and month (regdate)= month (now()) and day (regdate)= day (now())

这个有一些繁琐，还有简单的写法：

?

1	select * from table where date (regdate) = curdate();

date()函数获取日期部分, 扔掉时间部分，然后与当前日期比较即可
