I wrote up an article from my hackathon entry which explains how to solve a pretty difficult SQL problem:  https://github.com/burggraf/dead-or-alive/blob/main/SQL_Challenge.md

Let me know if you have any feedback on this article.  Is this SQL actually very easy and I’m just more of a noob than I thought, or would you consider it intermediate, or advanced SQL?   Is this how you solve problems like this with SQL?
