Hi!

No, those 1,2,3,4,5 are just the columns needed for the query to be valid, some of them are being printed on screen and some of them aren’t. This has been explained by Zaid in the lectures, maybe watch them again.

I know that sql can be a bit confusing in the beginning so look for information in internet, here’s an example:
