https://sqlbolt.com/ and then https://sqlzoo.net/ were great places for me to start.

Thanks for sharing these resources. Can I ask you what was your initial context or environment that made you learn SQL first? I mean what did encourage you to go and look for a solution?

+1 to SQLBolt, which is a nice quick introduction you can do in an hour or two. The automatic feedback of execute-as-you-type is great.
