Expected results
Solution postgres
SELECT
M.actor_id,
M.first_name,
M.last_name
FROM actor_movie M
INNER JOIN actor_tv T
ON T.actor_id = M.actor_id;
Explanation
This query selects the actor ID, first name, and last name from two tables: "actor_movie" and "actor_tv". It then joins these two tables on the "actor_id" column to only show actors who have worked in both movies and TV shows.
