mysql 按年份、季度、月度、周、日SQL统计查询
一、年度查询
查询 本年度的数据
SELECT *
FROM blog_article
WHERE year( FROM_UNIXTIME( BlogCreateTime ) ) = year( curdate( ))
二、查询季度数据
查询数据附带季度数
SELECT ArticleId, quarter( FROM_UNIXTIME( `BlogCreateTime` ) )
FROM `blog_article`
其他的同前面部分：查询 本季度的数据
SELECT *
FROM blog_article
WHERE quarter( FROM_UNIXTIME( BlogCreateTime ) ) = quarter( curdate( ))
三、查询月度数据
本月统计(MySQL)
select * from booking where month(booking_time) =
month(curdate()) and year(booking_time) = year(curdate())
本周统计(MySQL)
select * from spf_booking where month(booking_time) =
month(curdate()) and week(booking_time) = week(curdate())
四、时间段
N天内记录
WHERE TO_DAYS(NOW()) - TO_DAYS(时间字段) <= N
当天的记录
where date(时间字段)=date(now())
或
where to_days(时间字段) = to_days(now());
查询一周：
select * from table where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date(column_time);
查询一个月：
select * from table where DATE_SUB(CURDATE(), INTERVAL INTERVAL 1 MONTH) <= date(column_time);
查询'06-03'到'07-08'这个时间段内所有过生日的会员：
Select * From user Where
DATE_FORMAT(birthday,'%m-%d') >= '06-03' and DATE_FORMAT(birthday,'%m-%d')
<= '07-08';
统计一季度数据，表时间字段为：savetime
group by concat(date_format(savetime, '%Y '),FLOOR((date_format(savetime, '%m ')+2)/3))
或
select YEAR(savetime)*10+((MONTH(savetime)-1) DIV 3) +1,count(*)
from yourTable
group by YEAR(savetime)*10+((MONTH(savetime)-1) DIV 3) +1;
五、分组查询
1、年度分组
2、月度分组
3、先按年度分组，再按月度分组
4、按年月分组
SELECT count(ArticleId), date_format(FROM_UNIXTIME( `BlogCreateTime`),'%y%m') sdate FROM `blog_article` group by sdate
结果：
count( ArticleId ) sdate
17 0901
11 0902
5 0903
6 0904
2 0905
1 0907
12 0908
6 0909
11 0910
3 0911
其他方法参考：
我想做一个统计，数据库是mysql，统计出每天，每周，每月的记录数
建表的时候加个字段表示日期，然后查sql手册...
select count(*) from `table` where `date`='{某天}'
select count(*) from `table` where date_format(`date`,'%V')='{某周}'
select count(*) from `table` where date_format(`date`,'%c')='{某月}'
另一种方法：
select count( * ) from projects where editdate >= '2007-11-9 00:00:00' and editdate <=
'2007-11-9 24:00:00';
第三种方法：
每周的
SQL codeselect count(*) as cnt,week(editdate) as weekflg from projects where year(editdate)
=2007 group by weekflg
每月
SQL codeselect count(*) as cnt,month(editdate) as monthflg from projects where year
(editdate)=2007 group by monthflg
每天
SQL codeselect count(*) as cnt from projects group by date(edit
