Lesson 10 - View of Books Without Votes and Test with Invented Books

Dataset statusEasy SQL exercisesvv1

Exercise content

Create a view fp_books_without_votes that shows book_id and book_name for the books in books that have not received any votes in book_stars.
Insert these two invented books into the books table:
- 30001, 'Invented SQL Patterns', 'Imaginary Press'
- 30002, 'Fictional Data Stories', 'Imaginary Press'
Verify that the view also includes the two new books you just inserted.

Hints

Hint 1

The view must read from books and show only book_id and book_name. The required name is fp_books_without_votes.
Hint 2

You need to exclude the books that appear in book_stars. You can reason with a subquery on the already voted book_id values.
Hint 3

After CREATE VIEW, add two rows to books with INSERT. If the view is correct, it will include the new books too.
