按两个不同的日期和时间分组mysql

Question

I need to generate a report based on date and time .

My database table has payments recorded with amount and created datetime .

And, I need to group data like sum of payments from 9:30pm yesterday to 9:29pm today

(ie) instead of group by date(created_date). And then records between these time range .

I have the last two months records in my payments table.

Any help will be appreciated.

Thanks

Answer 1

Just add 2.5 hours to each date/time. This is most easily represented at 150 minutes:

group by date(created_date + interval 150 minute) 

Answer 2

Thanks for all the answers.

I ended up with this one - group by 24 hours

SELECT CONCAT( CONCAT(DATE(DATE_SUB(created, INTERVAL '21:30' HOUR_MINUTE)),
' 21:30:00') , ' - ' ,CONCAT(DATE(DATE_ADD(created, INTERVAL '2:30' HOUR_MINUTE)),
'  21:29:59') ) AS tintin, COUNT(*)  FROM test GROUP BY DATE(DATE_SUB(created, 
INTERVAL '21:30' HOUR_MINUTE)) ORDER BY DATE(created) DESC ; 

got some idea from here
