I doubt anyone here has any interest, but this is an exceptionally solid, high-level yet hands-on, SQL CRASH course. After a discouragingly long search, trying to find something neither too theoretical nor too basic (boring), I found this just yesterday. I am about 1.5 hours into the 4 hours (running videos as 2x normal speed) and I have seen enough to highly recommend this. A wonderful teacher; very to the point, and providing lots of hands on queries to run, yourself, on the provided database with SQLite and Postgres (haven't hit the Postgres yet).
Anyway, a really high quality, hands-on tutorial, and not just a come-on to spend money (he does ask for a donation, but he doesn't require it to give value). I'll probably donate something at the end.
Oh, BTW, A much belated “thank you” to Zimbler for recommending https://www.amazon.com/Advanced-Engineering-Mathematics-Erwin-Kreyszig a few years ago. I can't claim I've exactly completed the book, but I am buying my 2nd copy (too heavy to carry on the plane;-). It's nice to see math with pretty nearly everything explained in physics terms. (Even if I don't know the physics, it is much more motivating for me to have practical reasons to do the problems).
Who here was an engineer or physicist? I'm looking for other recommendations that might allow me to take some short cuts without missing the point of the journey entirely.
And I now return you to your regular programming!
