"Expecting results of L Chalkley, not L Chalkley" error.

Don't quite understand why I am getting this, did I do something wrong? The code below generates the correct table. Does the code challenge expect something else?

SELECT SUBSTR(first_name, 1, 1) || " " || last_name AS "initial" FROM customers;

Hi.

Just did the exercise myself. The task doesn't want you to concatinate the results, it wants it in two different columns having the initial and last_name in separate columns. You are getting the correct information, but not in the expected way.

SELECT SUBSTR(first_name, 1, 1) AS 'initial', last_name FROM customers; -> should do the trick.

Fantastic thanks, the response to my incorrect answer didn't make it clear.

Isn't that exactly what I said, guesses and and all?

Perhaps you don't have the right number of columns.

You didn't provide a link to the challenge so I could check, but just guessing from the name of the alias, I'd bet it was intended to be applied only to the result of the function. And I'd also guess that the last name was intended to be a separate column, with no concatenation involved.

If that's not it, please provide a link the course page and I'll take another look.

Apologies, first time here in a while.

Here is the question as well in case I did not link the page correctly.

In an ecommerce database there's a customers table with id, username, first_name, last_name, password, email and phone columns. Create a report from the customers table that shows their first initial of their first name and alias it as initial. Select their last name too.

Thank you for the help, I appreciate it!
