I had a discussion about this one with another tmd user - do you want both to work or both to return empty datasets?
Similar question to selecting columns - there are contexts where you want nonexistant columns to be silently ignored and contexts in which you expect an error in all cases.
Honestly not sure which direction to go.

I opt for throwing an exception in both cases. It's a similar case to Clojure vector which is index based. ([] 0)
throws IOOBE.
