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

This question doesn't clearly state how it wants longest_length formatted.

Tried a few different methods of stringing together the title and the length, but it doesn't like any of them. :/

Hi Jesse!

This passes:

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

And/But there are other ways to get the same or even better results.

I hope that helps.

Stay safe and happy coding!

Yeah, I realized after a while that the question wasn't asking to concatenate the title with the length into longest_length, but to simply select both. x.X

Thank you for your help!

Thanks a lot! Yes, it passes. It's very frustrating doing this kind of challenge where no answer seems to be correct.
