Databases Reporting with SQL Working with Text Getting the Length of a String

Help with a challenge - LENGTH()

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.

My Answer: SELECT title, LENGTH(title) AS "longest_length" FROM books ORDER BY DESC LIMIT 1;

Result: Bummer: There's something wrong with your SQL statement. Please review your code and try again.

Hi James. I think you want to order by length(title).
