Hi : This was a difficult question but i understood i needed to use LAG. However, in your solution, you get the LAG functions but dont use the second LAG. Can you clarify your solution and explain me a bit better.
Also is there a tips and tricks when finding out which options (group by having, case, or window functions)?
