Im not sure how to format concatenation operators
The concatenation operator in SQL Playground is two pipes
||, so to concatenate first_name with last_name, with a space between them, (if they are in a table named people and you want the return field to be called
full_name) you would do:
SELECT first_name || " " || last_name AS full_name FROM people
Put anything that you want to add to the results (like spaces, punctuation, angle brackets, etc.) in quotes. If you're still having trouble, post what you're trying and we can advise you on what needs to be corrected.
