To generate a count of certain column. I can't see what's wrong with my SQL code

My god. It's a simple question but I just can't see what's wrong with it.

Challenge: In the library database, how many books are with the genre of "Science Fiction"? Alias the result as scifi_book_count. The books table has the columns id, title, author, genre and first_published.

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

1 Answer

Your alias should come right after what you are aliasing, like this

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