按月进行统计
[sql]
select DATE_FORMAT(date,'%Y-%m') as month,sum(money) as money
from finance
where DATE_FORMAT(date,'%Y')=2010 group by month
order by month
[/sql]
按周统计
查看MySQL的manual
%X Year for the week where Sunday is the first day of the week, numeric, four digits; used with %V
%x Year for the week, where Monday is the first day of the week, numeric, four digits; used with %v
其中
1如果周一为一周的第一天,则(小写) DATE_FORMAT(date,'%x %v')
2如果周日为一周的第一天,则(大写) DATE_FORMAT(date,'%X %V')
[sql]
select DATE_FORMAT(date,'%x年-第%v周') as week,sum(money) as money from finance_base where DATE_FORMAT(date,'%Y')=2010 group by week
select DATE_FORMAT(date,'%x年-第%v周') as week,sum(money) as money from finance_base where DATE_FORMAT(date,'%Y')=2010 group by week
[/sql]
本文提供了一种使用SQL查询按月和按周对财务数据进行汇总的方法。通过DATE_FORMAT函数,可以方便地将日期格式化为指定的月份或周数格式,并按此格式进行分组求和。
