SQL select and count at the same time

Question

I am trying to select all from stuff and count the total amount of items in morestuff where stuff id = morestuff id.

select *,
    COUNT(morestuff.items) as total
from stuff,
    morestuff
where stuff.id = '{$id}'
    and morestuff.id = stuff.id

Obviously there is something wrong with my query, can anyone help?

Answer 1

SELECT s.*, coalesce(ms.Count, 0) as Count
FROM stuff s
left outer join (
    select id, count(*) as Count
    from morestuff
    group by id
) ms on s.id = ms.id
WHERE s.id='{$id}'
