Top Movies by Region

MediumSQL · PostgreSQL

Problem

Write a query to find the top three most-watched movies on Disney+ for each region over the last 30 days.

Use the movies and viewing_events tables. Count viewing events, include only events from the last 30 days relative to the current date, and return exactly three movies per region when available. Ties are resolved by ascending movie_id.

Output

  1. One row per ranked movie and region
  2. Columns: region, movie_title, watch_count, and movie_rank
  3. Sort by region ascending, then movie_rank ascending
