What is the name of the library database for this question? Normally it's told that the database name is "x".

select count(books) as scifi_book_count from library_database where genre = "Science Fiction";

This is my code for this challenge task. Normally the name of the database is given but here it is not, and the error I get is "SQL Error: No such table: ... "

Thank you.

The table name is contained in the challenge question.

The question is "In the library database, how many books are with the genre of "Science Fiction"? Alias the result as scifi_book_count."

Notice how some of the words are in a different font? These are hints about the database structure. It looks like you guessed (correctly) that "genre" was a column name. Similarly, "books" is the table name.
