Don't understand why my code isn't working: SELECT CONCAT(first_name," ",(username)) AS display_name FROM users;

I'm confused as to what I am doing wrong.

Hi Becca,

You'v missed the brackets on last name with double quotes inside, you are almost correct but wrong place.

Select the "first_name" followed by the username in parentheses and alias it as "display_name". For example "Andrew (chalkers)". There's a space between the end of the first_name and username in parentheses.

SELECT CONCAT(first_name, " (", username, ")") AS display_name FROM users;

Hope that helps.
