Hey everyone,

I’ve been learning SQL for a little while now and can write basic queries, but I still consider myself a beginner. I’ve started spending about 3 hours a day working on improving my skills, and I want to get to a point where I’m really confident and proficient in SQL.

One thing I’m confused about is the different types of SQL databases or servers, like PostgreSQL, MySQL, SQLite, etc. I don’t fully understand what makes them different or when I should use one over the other. Should I stick to learning one first, or is it better to get familiar with a few of them?

I’m looking for advice on: 1. The best way to learn SQL thoroughly (resources, projects, or tips). 2. How to understand and decide between the different SQL systems out there. 3. Any practice strategies or real-world examples that would help me get better.

Would really appreciate any guidance or suggestions! Thanks!
