Challenge: Help a Reader Find Their Favorite Genre

You are doing your job as a librarian when a reader approaches you saying they're in the mood for books from the Fantasy genre. They ask you to quickly find all the books in that category.

Opgave

Swipe to start coding

Write an SQL query using the WHERE clause to find the titles of all the books where the genre is "Fantasy".

The books table includes the columns: id, title, author, genre, publication_year, and price.

Note

Strings in SQL are case-sensitive. Therefore 'fantasy' is not the same as 'Fantasy'.
