Alias is right, but count is wrong - why? https://teamtreehouse.com/library/reporting-with-sql/aggregate-and-numeric-fun

Challenge task 1 of 2 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.

Type in your command below. Code: ...SELECT COUNT(genre) AS sci_fi_book_count FROM books WHERE genre = "Science Fiction"; ...

it returns the correct alias , but a count of 6 which says it's wrong. I don't see what I am doing wrong.

Thank you

I found out what I was doing wrong - the alias should be "scifi_book_count" instead of "sc_fi_book_count". But the error message was telling me the count was wrong, which is misleading. This was the message: Type in your command below.

Bummer! Your query didn't perform the correct count.

I've made the same mistake myself. Good job on correcting your own error!
