6,906 PointsReporting with sql, 2nd code challenge COUNT BY GROUP incorrect code
In the library database there's a books table. There are id, title, author, genre and first_published columns.
Write a query to count all the unique genres in the books table. Alias it as total_genres.
SELECT COUNT(DISTINCT(genre)) AS total_genre FROM books GROUP BY genre;
