Sample Solution:

-- Selecting specific columns from the tables movie, movie_direction, and director
SELECT movie.mov_title, mov_year, mov_dt_rel,
       mov_time,dir_fname, dir_lname 
-- Joining the movie and movie_direction tables based on the mov_id column
FROM movie
JOIN  movie_direction 
   ON movie.mov_id = movie_direction.mov_id
-- Joining the result with the director table based on the dir_id column
JOIN director 
   ON movie_direction.dir_id=director.dir_id
-- Filtering the result to include only records with mov_dt_rel before '01/01/1989'
WHERE mov_dt_rel < '01/01/1989'
-- Ordering the result by mov_dt_rel in descending order
ORDER BY mov_dt_rel DESC;

Sample Output:

                     mov_title                      | mov_year | mov_dt_rel | mov_time |      dir_fname       |      dir_lname

Code Explanation :

The said query in SQL which selects the movie title, year, release date, duration, director first name, and director last name for all movies that were released before January 1st, 1989. The results are sorted in descending order by release date.
The JOIN clause joins the movie table, movie_direction table, and director table based on the movie ID and director ID.
The WHERE clause filters the results to include only those movies that were released before January 1st, 1989.
Then sorts the results in descending order by release date.

Alternative Solutions:

Using WHERE Clause with Table Aliases:


SELECT m.mov_title, m.mov_year, m.mov_dt_rel, m.mov_time, d.dir_fname, d.dir_lname
FROM movie m, movie_direction md, director d
WHERE m.mov_id = md.mov_id
  AND md.dir_id = d.dir_id
  AND m.mov_dt_rel < '1989-01-01'
ORDER BY m.mov_dt_rel DESC;

Explanation:

This query uses the 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 released before January 1, 1989, and selects the movie title, year, release date, runtime, director's first name, and last name. The results are ordered by release date in descending order.
