Top 10 Most-Watched Shows

MediumSQL · PostgreSQL

Problem

Write a SQL query to find the top 10 most-watched shows in the last month.

Use the previous calendar month and define most-watched by the number of viewing sessions. Include shows with no sessions during that month only when needed to complete the top 10, and break ties by show_id ascending.

Output

  1. One row per show with columns show_id, show_title, and watch_count
  2. Include only the top 10 shows, ordered by watch_count descending and show_id ascending
