SQL concatenation question won't be resolved as correct answer.

A concatenation question in "Reporting with SQL" course asks to concatenate addresses in a database table in a specific format. When I submit my answer, I get incorrect response with the following comment: "Your query didn't retireve the addresses in the correct format. Expecting 2532 2nd ST, San Diego, California 90222. USA not 2532 2nd ST, San Diego, California 90222. USA."

When I copy and paste both formats in the correction to my computer's notepad, I find them both to be exactly the same.

My code is as follow: 

SELECT street || "," || " " || city || "," || " " || state || " " || zip || "." || " " || country FROM addresses;

I also tried 

SELECT street || ", " city || ", " || state || " " || zip || ". " || country FROM addresses;

Can someone please help?

Thank you

You forgot to write an alias for this query

SELECT street || ", " || city || ", " || state || " " || zip || ". " || country AS address FROM addresses;

That was the problem. The error message did not indicate it. Thank you!
