In this post, we'll dive into a master-level SQL question tackled by one of our seasoned experts. So without further ado, let's jump right in!
Scenario:
Imagine you're tasked with managing a database for a library. Your database contains three tables: `books`, `authors`, and `checkouts`. Each book has an associated author, and multiple copies of each book can be checked out by library members.
Question:
Write a SQL query to find the top 5 authors who have the most books checked out from the library.
Solution:
```sql
SELECT authors.author_name, COUNT(checkouts.book_id) AS num_checkouts
FROM authors
JOIN books ON authors.author_id = books.author_id
JOIN checkouts ON books.book_id = checkouts.book_id
GROUP BY authors.author_name
ORDER BY num_checkouts DESC
LIMIT 5;
```
This query starts by joining the `authors`, `books`, and `checkouts` tables together. Then, it counts the number of checkouts for each author, groups the results by author, orders them in descending order based on the number of checkouts, and finally limits the output to the top 5 authors.
