Invitation and roundup from Stuart Ainsworth.
Topic d’jour? JOINS (I’m in a fundamentals mood lately). Note that I also like creative and esoteric posts, so if you can find a way to apply SQL as a metaphorical language for community activity, I’ll read it and enjoy it. If you just want to tell me in a simple fashion the difference between a HASH and MERGE join, I’m cool with that, too.
