Wow. On the back of the completely wrong Code Challenge 8 “solution” we move on to the marvels of Challenge 10 where the entire instructions are:

Write a query using a window function with ROW_NUMBER and ORDER BY to see where each row falls in the amount of gross .

And from this we have to magically guess this precise solution in this precise order:

SELECT ROW_NUMBER()
OVER (
  ORDER BY gross
) AS 'row_num', title, week, gross
FROM box_office;

This is just terrible.

Yeah, this one was particularly bad. The initial instructions to the test say that there are multiple ways to solve the problems and that they don’t care how you do it, so long as the result is correct. Then you get to this question, and if you don’t have the code letter perfect, they reject it. Mine was wrong because I started the first SELECT criteria on line 2 and they want it on line 1 right beside the word SELECT. That is a totally trivial difference. Many times SELECT is on line 1 by itself and the SELECT criteria start on line 2. This should not be a problem.
