Howdy ya'll,

​

I've been working my way through a SQL course on Udemy (The Complete SQL Bootcamp 2022: Go From Zero to Hero) and have been enjoying it greatly so far. I feel like for the first half of the course I was retaining a ton, but as new topics have continued, I'm struggling to retain them simply due to not being able to practice as much since we've stopped using a larger practice database.

​

What recommendations do ya'll have for either practicing SQL to make sure I remember stuff, or how to find free, public databases to play around with? For reference, I would prefer ways to practice that have solutions I can reference in case I get stuck.

​

Right now, I don't have much use for SQL in my daily life since I'm not a data scientist or analyst, but I wanted to learn because I find the idea of interacting with databases fascinating. I'm sure being aware of all the possibilities in SQL puts me ahead of the game, but I want to make sure I don't just forget it all after finishing the bootcamp (which is outstanding btw).
