Question

I need to COUNT() (or maybe another MySQL function) rows of my query, but I need diferent counts, like this:

What I am getting:

   id  | date       | costumer_id
  -----+------- ----+-------------
   1   | 2012-10-05 | 103
   2   | 2012-10-05 | 103
   3   | 2012-10-05 | 103
   4   | 2012-10-05 | 59
   5   | 2012-10-05 | 59
   6   | 2012-10-05 | 90

What I need:

   id  | date       | costumer_id | count
  -----+------------+-------------+------
   1   | 2012-10-05 | 103         | 3
   5   | 2012-10-05 | 59          | 2
   6   | 2012-10-05 | 90          | 1

You need a simple group by query. I suspect you are leaving the id in the group by. Try something like this:

select max(id), date, customer_id, count(*)
from t
group by date, customer_id
order by 1
