I wrote a 3-part blog series on #sql. It's about getting back to the basics and reinforcing your mental model of things like SELECT, WHERE, JOIN, and GROUP BY.
Part 1 out today!
My second #sql blog post is up with a mental model for understanding JOINs.
Sorry for the self-promo, but I'm particularly proud of these.
And the final #sql post tackling a step-by-step explanation of GROUP BY
This is something I struggled with a lot early on and I'm excited to share my mental model.
