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

Issue with answering code challenge of length of title in SQL

Whenever I try to enter queries for this code challenge, there are always communication errors being reported. Is there any reason why this is happening and how to overcome this issue?

Hi Andrew, I seem to be having the same issue with the loss of connection for this challenge, I'm using the below query. I have tried this within the workspace using the customer table and username column and it worked fine.

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

Apologies, the challenge should work now :)

SELECT title, MAX(LENGTH(title)) AS longest_length FROM books;
