Hey Sevdiye you have some typos in the code you shared but KRIS has some great hints to get you going :thumbsup:

If you havent already worked through this challenge, your solution should look like this

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

Some hints:

  • the alias for longest title is "longest_length"
  • You can order by this alias: ORDER BY longest_length DESC
  • You will need to limit your results to one record
