I try to use strftime('%d',time) function to make Group by () by the day. But the problem that I would like to define each day not like the usual day (from 00:00 to 23:59) but from 5:45 to 5:45 next day.



Is it possible to do in SQLlite?

          I believe that the following may do what you wish :-



          strftime('%d',time) - (strftime('%H:%M',time) < '05:45')


          That is if the time is before 05:45 then 1 (true) is subtracted from the day when determining the GROUP BY argument and thus becomes the previous day.

            strftime('%d',time) - (strftime('%H:%M',time) < '05:45')


            That is if the time is before 05:45 then 1 (true) is subtracted from the day when determining the GROUP BY argument and thus becomes the previous day.
