Hi I have two tables, person and rating. person contains only an id while rating contains id, person_id, value, and movie_id. Now what I want to do is to query for all the people who have rated two diffferent movies, say with id's 45 and 56. I know how to do this for a single movie at a time with the following query: SELECT person.id AS personId FROM person, rating WHERE person.id = rating.person_id AND rating.value = 5 AND rating.movie_id = 45. But how do I in a single query search for people who have rated both movies 45 and 56 with the value 5? Thanks!
