表finance有倆個欄位如下

date date

money double(15,2)

下面需要對錶 finance的2010年財務資料，按月進行統計

Sql程式碼

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

檢視MySQL的manual

   其中

1如果週一為一週的第一天,則(小寫) DATE_FORMAT(date,'%x %v')

2如果週日為一週的第一天,則(大寫) DATE_FORMAT (date,'%X %V')

Sql程式碼

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
