下面是按周统计

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代码

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
