Why doesn't this work?

Challenge Task 2 of 3

Select the "first_name" concatenated with the username in parentheses and alias it as "display_name". For example "Andrew (chalkers)". Note that there's a space between the end of the first_name and username in parentheses. The name of the table is "users". Type in your command below, then press Enter.

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

the display of the fullname and users are specific and the '(' are in the prototype of the display that why you have to treat the '(' as character not as symbol : ''' SELECT CONCAT(first_name," (",username,")") AS display_name FROM users; '''

Josh, CONCAT can take more than two values. In this case it needs 4: first_name<br> " ("<br> username<br> ")"<br> Note the space before the opening parenthesis.

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

Thank you! Of course, the parentheses need to be passed in as strings! I missed that.
