Actually, there is still something that I don't understand, you replaced
my where clause joining table i and c with a left join. However, I would
like that condition to always be joining. To my understanding, left join
returns records of c even if there would be no corresponding record in i
(same with t with the second join). Here I have a table of clients, one
of clients that are registered this year 'i' and one table that keep
track of clients tickets. In my query, I would like to return ticket
counts only for the clients that are registered this year. With your
query it returns tickets for former clients as well.
