Sample Output:
act_fname | act_lname | role
----------------------+----------------------+--------------------------------
Woody | Allen | Alvy Singer
(1 row)
Sample Solution:
-- Selecting actor first names, last names, and roles
-- Using the 'actor' table
SELECT act_fname, act_lname, role
FROM actor
-- Joining with the 'movie_cast' table on act_id
JOIN movie_cast ON actor.act_id = movie_cast.act_id
-- Joining with the 'movie' table on mov_id and filtering for the movie 'Annie Hall'
JOIN movie ON movie_cast.mov_id = movie.mov_id AND movie.mov_title = 'Annie Hall';
Sample Output:
act_fname | act_lname | role
----------------------+----------------------+--------------------------------
Woody | Allen | Alvy Singer
(1 row)
Code Explanation:
The said query in SQL that retrieves the first name, last name, and role of actors who appear in the movie "Annie Hall".
The JOIN clauses connect the three tables together using their primary and foreign keys. This links the actor and movie_cast tables by their actor IDs, and the movie_cast and movie tables by their movie IDs.
The WHERE clause filters the results to only include actors who appear in the movie "Annie Hall".
Alternative Solutions:
Using INNER JOIN:
SELECT actor.act_fname, actor.act_lname, movie_cast.role
FROM actor
INNER JOIN movie_cast ON actor.act_id = movie_cast.act_id
INNER JOIN movie ON movie_cast.mov_id = movie.mov_id
WHERE movie.mov_title = 'Annie Hall';
Explanation:
This query uses INNER JOINs to combine the actor, movie_cast, and movie tables based on their respective IDs. It then applies a WHERE clause to filter for movies with the title 'Annie Hall' and selects the actor's first name, last name, and role.
Using WHERE Clause with Table Aliases:
SELECT a.act_fname, a.act_lname, mc.role
FROM actor a, movie_cast mc, movie m
WHERE a.act_id = mc.act_id
AND mc.mov_id = m.mov_id
AND m.mov_title = 'Annie Hall';
Explanation:
This query uses the older comma-separated syntax for joining tables and specifies the join conditions in the WHERE clause. It then applies a WHERE clause to filter for movies with the title 'Annie Hall' and selects the actor's first name, last name, and role.
