> Change Expression.isDeterministic() to return an ENUM with three values
> DETERMINISTIC -  the expression returns the same output every time given the same input.
> UNDETERMINISTIC_ROW - the expression should be computed for every row
> UNDETERMINISTIC_STMT - the expression should be be computed for a given statement only once
> See PHOENIX-1001
