One small gotcha that Anders Karlsson pointed out to me through Paul DuBois: This one-query union syntax doesn't allow you to use the ALL keyword after UNION (since the UNION keyword isn't even there). That means it will always eliminate duplicate rows (like DISTINCT). That hasn't come up when I've used it, since I've never been selecting result sets that could contain duplicate rows, but it's something to keep in mind. -- Keith C.
