Sample Solution:

-- Selecting columns 'mov_title', 'mov_year', 'mov_time', 'mov_dt_rel', 'mov_rel_country'
-- from the 'movie' table
-- Filtering results where 'mov_rel_country' is not in the specified list ('UK')
SELECT mov_title, mov_year, mov_time, 
       mov_dt_rel AS Date_of_Release, 
       mov_rel_country AS Releasing_Country
FROM movie
WHERE mov_rel_country NOT IN ('UK');

Sample Output:

                     mov_title                      | mov_year | mov_time | date_of_release | releasing_country

(3 rows)

Code Explanation:

The said query in SQL which selects the movie title, year, duration, date of release, and releasing country from the 'movie' table, but only for movies that were not released in the UK.

Alternative Solutions:

Using IN Operator:


SELECT mov_title, mov_year, mov_time, 
       mov_dt_rel AS Date_of_Release, 
       mov_rel_country AS Releasing_Country
FROM movie
WHERE mov_rel_country NOT IN ('UK');

Explanation:

This solution uses the NOT IN operator to exclude movies released in the UK from the result set.

EXISTS Clause:


SELECT mov_title, mov_year, mov_time, 
       mov_dt_rel AS Date_of_Release, 
       mov_rel_country AS Releasing_Country
FROM movie m
WHERE NOT EXISTS (
    SELECT 1
    FROM movie
    WHERE mov_rel_country = 'UK' AND mov_id = m.mov_id
);

Explanation:

This solution uses the EXISTS clause to check for the existence of a movie with a UK release in a subquery. If no such movie is found, it includes the record in the final result set.

Using a JOIN:


SELECT m.mov_title, m.mov_year, m.mov_time, 
       m.mov_dt_rel AS Date_of_Release, 
       m.mov_rel_country AS Releasing_Country
FROM movie m
JOIN (
    SELECT mov_id
    FROM movie
    WHERE mov_rel_country <> 'UK'
) AS filtered ON m.mov_id = filtered.mov_id;

Explanation:

This solution performs an inner join between the movie table and a subquery that selects mov_id for movies not released in the UK. This ensures that only relevant records are included in the final result set.
