I am finding that I am encountering variables containing null more often as I interface data to the IBM i that originated from other software and databases. How to handle nulls is becoming one of the more popular questions I am asked.
What is null? Dictionary.com defines it as:
- without value, effect, consequence, or significance.
- being or amounting to nothing; nil; lacking; nonexistent.
