> SELECT genre, COUNT(genre) "genre_count" FROM books WHERE genre NOT NULL GROUP BY genre; whats wrong?
SELECT genre, COUNT(genre) "genre_count" FROM books WHERE genre NOT NULL GROUP BY genre;
it does count each genre and display the table as asked. Whats wrong?
I think you mean:
Select genre, count(genre) as "genre_count" from books Group by genre Having genre IS NOT NULL;
