Joining two tables and then selecting only info based on criteria in a third table

Question

So I joined two tables but I only want to select info from that join based on criteria defined in another table. I only want info from the first join where the actors name is in the popactor table.

select  h.movie,
        h.released,
        a.rating,
        h.actor
  from  hollywood.stars h
    inner join starmovies a on h.movie =a.title
    inner join popactor p on p.actor = h.actor
  where h.movie = a.title and p.actor = h.actor;

Answer 1

First your where clause is useless as the 2 conditions are already in the ON clause of your joins so you could get rid of it. Then you have two ways to achieve what you are looking for : As suggested in comments :

select 
  h.movie,
  h.released,
  a.rating,
  h.actor
from 
  hollywood.stars h
  inner join starmovies a on h.movie = a.title
where h.actor IN (select actor FROM popactor) 

OR as you already did :

select  
  h.movie,
  h.released,
  a.rating,
  h.actor
from 
  hollywood.stars h
  inner join starmovies a on h.movie =a.title
  inner join popactor p on p.actor = h.actor

Of course, if h.actor nor p.actor is the actor name on which you want to filter, you need to replace these fields in both queries with the right ones.
