I'm not sure why I'm getting an error when trying to run this code. My notes show that this should be accurate.

SELECT title, LENGTH(title) AS length FROM books ORDER BY length DESC LIMIT 1;

You have two issues:

1) The alias name is longest_length

2) length is a function and can't be used on its own in an order by clause. You can however order by the alias longest_ length or by length(title).
