The API with the problem is the SQL language. It's there that the columns
become inaccessible. It seems silly for the language to let you create
variables that you can't reference.
Yes it's true that you could access them from the result set but that's even
worse. You have variables that you can't access from within the language but
that can escape to the outside world to cause real effects.
