Mysql query running COUNT every time the same value is fetched - php

Question

I am currently using Laravels QueryBuilder to fetch all users and the number of open tickets they have.
The query looks like this:
return DB::table('users')
->leftjoin('tickets', 'users.organisation', '=', 'tickets.organisation')
->leftjoin('tickets_statuses', 'tickets.ticket_id', '=', 'tickets_statuses.ticket_id')
->select(
'users.organisation',
DB::raw('COUNT(tickets.ticket_id) as tickets')
)
->where('tickets_statuses.status_id', 0)
->where('users.admin', false)
->groupby('users.organisation')
->get();
The issue is, I may have 6 users that belong to the same organisation. So if 80 open tickets belong to the organisation, the query would do 80 x 6 for some reason resulting in 480 open ticket count when it should be 80.

As you can see, multiple users belong to an organisation. Now if I ran the following query:
SELECt ticket_id from tickets where organisation = 'Corkery Group';
I receive the following:
80 rows in set (0.00 sec)
From the query, I am wanting to get the organisation name and count all the tickets that belong to an organisation.
When I run the original query, it returns a result set of 480 rows when it should only return 80 rows.

Answer 1

There was a very good answer here Why do the results of this MySQL query get multiplied by each other? that put me in the right direction.
In my scenario, for every user with an organisation the COUNT() would be executed. The issue is, if I have 6 users which are part of one organisation, it's going to run the COUNT() statement six times.
So going back to my query, I didn't need the users table. It was irrelevant because I was only trying to access organisations with tickets & the organisation name - all of which are stored in the tickets & tickets_statuses tables. Which left me with a working query:
return DB::table('tickets')
->leftjoin('tickets_statuses', 'tickets.ticket_id', '=', 'tickets_statuses.ticket_id')
->select('tickets.organisation', DB::raw('COUNT(tickets.ticket_id) as tickets'))
->where('tickets_statuses.status_id', 0)
->groupby('tickets.organisation')
->havingRaw('COUNT(tickets.ticket_id) > 1')
->get();
