I want to get better at databases. I had already been working with them on my own when I had the opportunity to take a class in them, but I kinda fucked off thinking that my suprr 1337 PHP MySQL experience was enough; and I am kinda regretting that now that I have the experience to know that I don't really know shit. Like, I know shit, enough to be dangerous, but...
Anyone got any good resources on the topic? Down to read it all; Theory, hands on query crafting, etc. Things related to the care and feeding of the elephant database would be a plus, too.
