mysql - SQL - Count of each category of film ED CHASE has been in -


this question has answer here:

i'm trying return table category.name , count of number of films ed chase in in category. query should return every category if ed chase hasn't been in film in category.

this schema:

all have far way select category names. haven't been able tie ed chase in way though.

select category.name film_category inner join category on film_category.category_id = category.category_id,

i've tried join these results film_actor, keep getting syntax errors when trying that.

select category.name film_category inner join category on film_category.category_id = category.category_id, inner join film_actor on film_category.film_id = film_actor.film_id

try this:

select c.category_id, c.name, count(a.actor_id) category c left join film_category fc on c.category_id = fc.category_id left join film f on fc.film_id = f.film_id left join film_actor fa on f.film_id = fa.film_id  left join actor on fa.actor_id = a.actor_id ,                          a.first_name = 'ed' , a.last_name = 'chase' group c.category_id, c.name

the query returns 1 record each category if category has no films associated it. can change , use inner join film_category in case want categories having at least one associated film.
