W3Schools Online SQL Tutorial: https://www.w3schools.com/sql/default.asp

Dunno how far that will get you; certainly seems to cover the basics of syntax and so on. The harder part is the mindset, thinking in sets and being able to translate what you want to do into SQL. But I guess that's the hardest part of... Well, pretty much everything. And hard to package into lessons; maybe it's something everyone has to grok for themselves, so it can't hurt to try this first -- at least it seems free of charge. (I've looked up stuff, probably including SQL AFAICR, on W3Schools and never paid anything.)

I suppose one of the best things you could do is download some simple SQL client (and possibly server), SQLite or MariaDB or Firebird or something, and an example dataset like Northwind Trading or some such, and just start playing around.

Hope this helps!




Thanks for sharing! The idea of also downloading some stuff and just playing around is helpful. Might do that alongside courses
