group by date_format for each day

Question

My I'm having problems with a query. Here is what I have

SELECT COUNT(id) as Counted
    FROM referral_code_logs
        GROUP BY DATE_FORMAT(time_stamp, '%c/%e/%y');

I am trying to see the amount of referrals each day has. The part I'm having problems with is the date_format.

Table layout

Here are how the time_stamps are entered in the Table: (month/day/year) month is 1-12 day is 0-31 year is YY

Time_stamps

Answer 1

You just need to add in the date to the select part:

SELECT DATE_FORMAT(STR_TO_DATE(time_stamp, '%c/%e/%y'), '%c/%e/%y') as DT
       ,COUNT(id) as Counted
    FROM referral_code_logs
        GROUP BY DATE_FORMAT(time_stamp, '%c/%e/%y');
