Alternative Answer Using Case

in SQL / SQL Subqueries nested in SELECT and FROM

I started learning the 'case' statement, and I just couldn't not come back and rewrite this ̶u̶g̶l̶y̶ overcomplicated query XD

Could this query be less efficient though?

Hi A V!
Thanks for reaching out.

This query also solves the task, but the idea is to use subqueries.

Hope this helps.
Best,
Tsvetelin
