SELECT genre, COUNT(genre) AS genre_count FROM books GROUP BY genre; Can you please tell me what is wrong with this

SELECT genre, COUNT(genre) AS genre_count FROM books GROUP BY genre;

Can you please tell me what is wrong with this query. It checks out in the SQL playground.

To get the count of books, you need to count the titles (not the genre).

Therefore if you change COUNT(genre) to COUNT(title) in your statement, that should deliver the result.

No problem!
