Yeah dude.
For something I love and want to use all the time, like Python, I'll make my own cheat sheet. For something like MySql, where I have to kick myself to pay attention every thirty seconds, there's no way I'm doing my own cheat sheet. I can barely bring myself to do the actual work.
Once you make the mental transition from "mysql" to "SQL" and actually treat it as a language, it gets interesting.

So I take it you must be used to reading documentation and picking up new languages pretty quickly? If you must keep going to the documentation to remember a function, copy it out. I don't see how needing to dig through out of order lists is any more useful than digging through long winded documentation. The point of a cheat sheet is not just remembering the thing, but finding it quickly.
This is an awesome resource.
