i'd like to filter the leads in the hopper by birthday.
but i don't know how to do that.
in the sql database the field named DATE_OF_BIRTHDAY.
my request:
only leads with birthday of today or before should be phoned.
the first leads should be the customers with the birthday today and then every customer who had birthday in the past.
DATE_OF_BIRTHDAY <= now() GROUP BY DATE_OF_BIRTHDAY
is it possible, if yes, how?

thanks a lot
best regards
philip
