Sample Solution:
-- Selecting director first names, last names, and movie titles
-- Using the 'director' table
SELECT dir_fname, dir_lname, mov_title
FROM director
-- Performing natural join with 'movie_direction' to link directors with movies
NATURAL JOIN movie_direction
-- Further joining with 'movie' using natural join to get additional movie details
NATURAL JOIN movie
-- Completing the join with 'movie_cast' to associate roles with the movies
NATURAL JOIN movie_cast
-- Filtering for rows where the role is not NULL and the movie title is 'Eyes Wide Shut'
WHERE role IS NOT NULL AND mov_title = 'Eyes Wide Shut';
Sample Output:
dir_fname | dir_lname | mov_title
----------------------+----------------------+----------------------------------
Stanley | Kubrick | Eyes Wide Shut
(1 row)
Code Explanation:
The said query in SQL that retrieves the first name and last name of the director, as well as the title of the movie, and returns only the rows where the role is not null, and the movie title is "Eyes Wide Shut".
The NATURAL JOIN clauses connect the four tables together using their common column names. The director and movie_direction are joined on their shared dir_id, movie_direction and movie are joined on their shared mov_id, and movie and movie_cast are joined on their shared mov_id.
The WHERE clause filters the results to only include rows where the role column is not null that means at least one actor is associated with the movie and the mov_title column is "Eyes Wide Shut".
Alternative Solutions:
Using INNER JOIN:
SELECT d.dir_fname, d.dir_lname, m.mov_title
FROM director d
JOIN movie_direction md ON d.dir_id = md.dir_id
JOIN movie m ON md.mov_id = m.mov_id
JOIN movie_cast mc ON m.mov_id = mc.mov_id
WHERE mc.role IS NOT NULL
AND m.mov_title = 'Eyes Wide Shut';
Explanation:
This query uses INNER JOINs to combine the director, movie_direction, movie, and movie_cast tables based on their respective IDs. It then applies a WHERE clause to filter for movies with the title 'Eyes Wide Shut' and selects the director's first name, last name, and the movie title.
Using JOIN with ON Clause:
SELECT d.dir_fname, d.dir_lname, m.mov_title
FROM director d
JOIN movie_direction md ON d.dir_id = md.dir_id
JOIN movie m ON md.mov_id = m.mov_id
JOIN movie_cast mc ON m.mov_id = mc.mov_id
WHERE mc.role IS NOT NULL
AND m.mov_title = 'Eyes Wide Shut';
Explanation:
This query also uses JOINs with explicit ON clauses to combine the tables. It applies a WHERE clause to filter for movies with the title 'Eyes Wide Shut' and selects the director's first name, last name, and the movie title.
Using WHERE Clause with Table Aliases:
SELECT d.dir_fname, d.dir_lname, m.mov_title
FROM director d, movie_direction md, movie m, movie_cast mc
WHERE d.dir_id = md.dir_id
AND md.mov_id = m.mov_id
AND m.mov_id = mc.mov_id
AND mc.role IS NOT NULL
AND m.mov_title = 'Eyes Wide Shut';
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 'Eyes Wide Shut' and selects the director's first name, last name, and the movie title.
