Sample Solution:
-- Selecting specific columns from the actor, movie_cast, movie_direction, director, and movie tables
SELECT dir_fname, dir_lname, mov_title, act_fname, act_lname, role
-- Joining the actor and movie_cast tables using the act_id column
FROM actor
JOIN movie_cast
ON actor.act_id = movie_cast.act_id
-- Joining the result with the movie_direction table using the mov_id column
JOIN movie_direction
ON movie_cast.mov_id = movie_direction.mov_id
-- Joining the result with the director table using the dir_id column
JOIN director
ON movie_direction.dir_id = director.dir_id
-- Joining the result with the movie table using the mov_id column
JOIN movie
ON movie.mov_id = movie_direction.mov_id
-- Filtering the result to include only records where act_fname is 'Claire' and act_lname is 'Danes'
WHERE act_fname = 'Claire'
AND act_lname = 'Danes';
Sample Output:
dir_fname | dir_lname | mov_title | act_fname | act_lname | role

Code Explanation :
The said query in SQL which selects the first name and last name of a director, the title of a movie, the first name and last name of an actor, and the role they played in the movie. It only includes movies where Claire Danes appeared.
A join is performed between the actor table and the movie_cast table using the act_id column, then joins the movie_direction table using the mov_id column from the movie_cast table, then joins the director table using the dir_id column from the movie_direction table, and finally joins the movie table using the mov_id column from the movie_direction table.
WHERE clauses are used to filter the search results to include only movies where Claire Danes appeared in one or more of them. It does this by checking that the actor's first name is "Claire" and the last name is "Danes".
Alternative Solutions:
Using EXISTS Clause:
SELECT dir_fname, dir_lname, mov_title, act_fname, act_lname, role
FROM actor
JOIN movie_cast ON actor.act_id = movie_cast.act_id
JOIN movie_direction ON movie_cast.mov_id = movie_direction.mov_id
JOIN director ON movie_direction.dir_id = director.dir_id
JOIN movie ON movie.mov_id = movie_direction.mov_id
WHERE EXISTS (
SELECT 1
FROM actor a
WHERE a.act_id = actor.act_id
AND a.act_fname = 'Claire'
AND a.act_lname = 'Danes'
);
Explanation:
This SQL query uses the EXISTS clause with a subquery to check if there exists an actor with the specified first and last name. If such an actor exists, the main query includes the corresponding movie and director information.
Using a Self-Join:
SELECT d1.dir_fname, d1.dir_lname, m1.mov_title, a1.act_fname, a1.act_lname, mc1.role
FROM actor a1
JOIN movie_cast mc1 ON a1.act_id = mc1.act_id
JOIN movie_direction md1 ON mc1.mov_id = md1.mov_id
JOIN director d1 ON md1.dir_id = d1.dir_id
JOIN movie m1 ON md1.mov_id = m1.mov_id
JOIN actor a2 ON a1.act_id = a2.act_id
WHERE a2.act_fname = 'Claire' AND a2.act_lname = 'Danes';
Explanation:
This SQL query involves a self-join on the actor table. It joins the actor table twice (as a1 and a2), allowing us to filter for actors with specific names (Claire Danes in this case) using the second instance (a2) in the WHERE clause.
Using a Subquery with IN Clause:
SELECT dir_fname, dir_lname, mov_title, act_fname, act_lname, role
FROM actor
JOIN movie_cast ON actor.act_id = movie_cast.act_id
JOIN movie_direction ON movie_cast.mov_id = movie_direction.mov_id
JOIN director ON movie_direction.dir_id = director.dir_id
JOIN movie ON movie.mov_id = movie_direction.mov_id
WHERE (act_fname, act_lname) IN (('Claire', 'Danes'));
Explanation:
This SQL query uses a subquery with an IN clause to filter the results for actors with the specified first and last name combination. It checks if the combination matches 'Claire Danes'.
