> As is pointed out in [1], if the operand is not a literal, the value returned
> by SqlOperatorBinding#getOperandLiteralValue is null.
> However, the two implementations in RexCallBinding and SqlCallBinding do not
> really follow. From the implementation point of view, they will call other
> two utilities methods which could throw exceptions [2], [3].
