2,406 PointsCounting with SQL
SELECT COUNT(*) FROM books WHERE genre = "Science Fiction" AS scifi_book_count;
Trying to return the number of books in a database that are in the "Science Fiction" genre, and alias it. Tried a few different variations but not sure what I'm doing wrong.
Thanks!

SELECT COUNT(*) AS scifi_book_count FROM books WHERE genre = "Science Fiction";
