This is the part I love.  There is no definitive answer, no place to go
to find these things.  Hopefully we'll solve that with the new website.
Here's another one I found:

WHERE MYNAME BETWEEN 'LAVERNE' AND 'SHIRLEY'

>From what I've read, in some databases, this will include records where
MYNAME is LAVERNE, but not SHIRLEY, whereas some databases will include
both and some will include neither:
http://www.w3schools.com/sql/sql_between.asp.

Hopefully there's something about this in the ISO SQL99 standard, but
I'm not up to ponying up $90 to download five PDF files (or $530 for the
printed versions!).
