Confused why my query isn’t working here:

I think it is because I am trying to call on the second column as 2. Other than that, my query is the same as the hint. Are there circumstances where you can’t call on the column number like this?


I got the exact same problem, I’m guessing that when you want to use actual values of number (in this case 400)other than notation related by a number(like 2 in this incident) in the same sentence, it doesn’t work. Since ‘Group by 1’ works just fine.

But I might be wrong.
