In the library database there's a books table. There are id, title, author, genre and first_published columns.
I'm trying to figure out what is going on with my code. When I run the code, the result is exactly what the question is asking for. It gives me the name of each genre without duplicating it and it gives me the number of books in each. Even though I'm correct, I still can't get credit if I just skip to the next lesson.

I noticed that as I was going through the SQL course (just finished today) I would run into this issue only when I wasn't selecting the information in the order that it was asked for. This was usually me unconsciously thinking that if I was going to present that data, I felt it would be better presented in a different order. Be sure that you are populating the result table exactly as it is asked for. Hope this helps XD
