如何按日期分组而不是按时间分组

Question

My query return like below

date                    count
November 19,2019,11:58 PM 2
November 19,2019,11:59 PM 2

Is there any way to do like

November 19,2019 4
November 20,2019 2

Answer 1

Seems your date is not a standard mysql date time format. We need to format it first using str_to_date function.

select cast(str_to_date(dateC, '%M %d,%Y,%h:%i') as date), count(1) from Test
group by cast(str_to_date(dateC, '%M %d,%Y,%h:%i') as date)

see dbfiddle .

Answer 2

follow this query:

I get this result when I execute the query

select count(*) from listings  group by date(created)
