Challenge Task 1 of 1 In the library database there's a books table with the columns id, title, author, genre and first_published. Find the book with the longest title. Show the title and then the length. Alias the result of the length calculation to be longest_length. Only retrieve the longest book.

i wrote this query what's missing?

SELECT title, length(title) as longest_lenght FROM books order by longest_lenght desc limit 1;
