In an ecommerce database there's a customers table with id, username, first_name, last_name, password, email and phone c

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

What did I do wrong?

You have the right idea, you're just doing more than this problem actually wants. To clarify, what it wants you to do is:

Select 2 things: first initial of the first name and the last name, and alias one of them: first initial as initial.

The result should be a table with two columns like this:

initial       last_name
A             Smith
J             Jones
B             Franklin

I still dont understand, when i run it i get the error : Bummer! Expecting results like L & Chalkley not L & Chalkley. ;

I think the problem is because of the column

Oh so you dont need the '&' between the initial and last name. I got it now .. The wording of the error message confused me.

Also, something to note, it's unnecessary to alias last_name as anything, because the challenge doesn't ask for an alias, and aliasing it as itself like "last_name AS last_name" is redundant and changes nothing.
