Hello! I can't get through Challenge task "Getting the Length of a String"
My answer is: SELECT title, LENGTH(title) AS length FROM books AS longest_length ORDER BY length DESC LIMIT 1; I checked this answer in a database, it's correct.

This statement has no syntax errors, but it does something different from what the challenge asked for. This kind of "false positive" is a common problem when testing challenge code outside of the challenge.
The challenge asked that the column that shows the calculation result to be aliased as "longest_length" but this code names that column "length" instead.
This code also creates an alias for the table, but that isn't needed for this challenge.

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