EXPLAIN Cheatsheet
Posted by Sheeri Cabral on Apr 22, 2008
At the 2008 MySQL Conference and Expo, The Pythian Group gave away EXPLAIN cheatsheets. They were very nice, printed in full color and laminated to ensure you can spill your coffee* on it and it will survive.
For those not at the conference, or those that want to make more, the file is downloadable as a 136Kb PDF at explain-diagram.pdf
* or tea, for those of us in the civilized world.

Thanks for the cheatsheet. I appreciate it. I will have it at my desk to spill coffee on. Guess that means I am not civilized :)

Thanks, Sheeri. My laminated copy is attached safely at my desk. Bring some more of this goodness!
That was by far my favorite handout.
