123 |
SELECT * FROM blog_article WHERE year( FROM_UNIXTIME( BlogCreateTime ) ) = year( curdate( )) |
Second, query quarterly data

12 |
SELECT ArticleId, quarter( FROM_UNIXTIME( `BlogCreateTime` ) ) FROM `blog_article` |
Other previous sections: Querying data for the quarter
123 |
SELECT * FROM blog_article WHERE quarter( FROM_UNIXTIME( BlogCreateTime ) ) = quarter( curdate( )) |

select * from spf_booking where month(booking_time) = month(curdate()) and week(booking_time) = week(curdate()) |
Iv. time period
N Days of recording
1 |
WHERE TO_DAYS(NOW()) - TO_DAYS(时间字段) <= N |
Record of the day
1 |
where date (时间字段)= date (now()) |
Or
1 |
where to_days(时间字段) = to_days(now()); |
Query one week
1 |
select * from table where DATE_SUB(CURDATE(), INTERVAL 7 DAY) <= date (column_time); |
Query one months
1 |
select * from table where DATE_SUB(CURDATE(), INTERVAL INTERVAL 1 MONTH) <= date (column_time); |
Query ' 06-03 ' to ' 07-08 ' for all birthdays during this time period:
12 |
Select * From user Where DATE_FORMAT(birthday, ‘%m-%d‘ ) >= ‘06-03‘ and DATE_FORMAT(birthday, ‘%m-%d‘ )<= ‘07-08‘ ; |
Statistics quarterly data, table Time field: Savetime
1 |
group by concat(date_format(savetime, ‘%Y ‘ ),FLOOR((date_format(savetime, ‘%m ‘ )+2) /3 )) |
Or
123 |
select YEAR(savetime)*10+((MONTH(savetime)-1) DIV 3) +1,count(*) from yourTable group by YEAR(savetime)*10+((MONTH(savetime)-1) DIV 3) +1; |
Five, group query
1. Group of the Year
2. Monthly Group
3, first group by year, and then by the monthly group
4. GROUP BY month
1 |
SELECT count(ArticleId), date_format(FROM_UNIXTIME( `BlogCreateTime`), ‘%y%m‘ ) sdate FROM `blog_article` group by sdate |
Results:
123456789101112131415161718192021 |
Count ( ArticleId ) sdate 17 0901 11 0902 5 0903 6 0904 2 0905 1 0907 12 0908 6 0909 11 0910 3 0911 |

I want to do a statistic, the database is MySQL, the daily, weekly, monthly number of records
when the table is created by adding a field to indicate the date, and then check the SQL manual ...
123 |
select count (*) from ' table ' where ' date ' = ' {One day} ' Select count (*) from ' table ' where date_format (' date %V ' ) = ' {a week} ' Select count (*) from ' table ' where date_format (' date ) = ' {a month} ' |
Another way:
12 |
select count( * ) from projects where editdate >= ‘2007-11-9 00:00:00‘ and editdate <= ‘2007-11-9 24:00:00‘ ; |
The third method:
of the Week
12 |
SQL codeselect count(*) as cnt,week(editdate) as weekflg from projects where year(editdate) =2007 group by weekflg |
Monthly
12 |
SQL codeselect count(*) as cnt,month(editdate) as monthflg from projects where year (editdate)=2007 group by monthflg |
Every day
1 |
SQL codeselect count(*) as cnt from projects group by date (editdate) |
