Null and Not Null "Mike Hammonds" <mhammonds@knowledgeinenergy.com>
Re: Null and Not Null "Robert B. Easter" <reaster@comptechnews.com>
Hi Mike, Your question is sort of broad. Could you be more specific? However, a general reply to your broad question (and a source of confusion for many people) is that Null does not mean "empty", rather it means "undefined" (as in "the answer to a poorly formed question") -- which is why Null = Null is false.
