DB aside the query you are looking for is very simple SQL. The only real trick is using
SUM(case when status = 1/0 then 1 else 0 end
to obtain the proper counts.
Any reference materials covering table joining and group by will give you the syntax and examples needed to write your
query.
The lack of response is because most people are not going to bother answering very simple queries that beginner
referencematerials cover adequately. Plus, you didn't display any effort in attempting to solve the question yourself;
youcan do this by showing and and asking what you did wrong as opposed to simply asking for an answer.
