Does anyone have any good SQL resources?

I've never touched SQL but some friends said that its a language you can basically learn in an afternoon, so I put it on my CV and applied to some jobs that say they want SQL lol. But now I've actually gotten an interview and I'd like to not get caught out as bullshitting - is it as easy as my friends say and do any of yall have some good resources about learning/using it? In the past I've had pdfs that take you from nothing to profiecency in a language and I'd love something similar, but now that I've graduated I don't have access to stuff like that anymore. I have a shittonne of experience in python if that helps (although at a glance nothing i'm seeing online looks much like python, but i'm told that you can implement it through python or something?)

Most stuff I can find quickly either try to make you pay for it or they're videos instead of text and that doesn't really play well with the adhd. Do you guys have anything? Thanks for the help scamming a corporation comrades
