    seems like there’s an issue with case 3. the person_id and from surveillance_records doesn’t match up with the person_id in the hotel_checkins table when joined on hotel-checkin_id

        Yeah we have IDEs to color keywords for us these days. Caps is just extra work

          Capital letters are bigger, thus they use bigger bytes and use too much disk space and memory. That’s why most programming languages use lowercase, and why the most common loop variable is i.

    I tried to hit F5 to run a query and it refreshed the page lol

    edit: I’m also slightly annoyed that the table names are a mix of singular and plural

      I have some time to kill before having to run some errands. I’ve started with the first one and it’s pretty fun!

      Said “fuck yeah” a couple times to myself when I got the answer right. I’ve not used SQL before but I’ve got a decent grasp (as in I get the basics) on programming languages so it’s somewhat intuitive to me

      Thanks for the links!! I look forward to continuing when I get back

      My gosh, these are incredible. Thank you for sharing them. I cried at Select Star; that is legitimate art.
