MySQL: Group By & Count Multiple Fields

Question

If I have a single field, say, project_id where I want to count the occurrences, I would do something like:

select project_id, count(project_id) as count fro         


        

Answer 1

select project_id, service_id, count(*) as count 
from tbl group by project_id, service_id
order by count(*) desc

Just add service_id to your group by and select list. That should do it.

EDIT -

As per comment from @Rajah it seems that for your expected output, you need to use

order by project_id asc, service_id asc
