mysql將資料按天,周,半月,月分組

最近有個需求,要求查出今天,一周,15天,乙個月的資料

created是時間戳

按天分組:

select sum(income) as income,

from_unixtime(created, '%y-%m-%d') as create_data
from `income`
group by create_data
order by create_data desc

select sum(income) as income,

from_unixtime(created, '%y-%u') as create_data
from `income`
group by create_data
order by create_data desc

如果時間為 2019-01-1,代表上半個月,2019-01-2代表下半個月

select sum(income) as income,

if(from_unixtime(created, '%d') <= 15, from_unixtime(created, '%y-%m-1'), from_unixtime(created, '%y-%m-2')) as create_data
from `income`
group by create_data
order by create_data desc

select sum(income) as income,

from_unixtime(created, '%y-%m') as create_data
from `income`
group by create_data
order by create_data desc
