Updatable ResultSets need to check for an empty ResultSet because

isBeforeFirst and isAfterLast both return false for an empty result
so the checking to make sure the user is on a valid row wasn't
working.

Also don't allow an insert without specifying at least one column
value because INSERT INTO tab() values() is a syntax error.
