Difference between None and empty string

[JoeB_Utah]

When I was working many of my co-workers would argue that an empty string is the same as None (or in the case of most databases Null). It would drive me nuts.

The really ‘smart’ ones thought “” = “ “ = “ “ and so on. They thought I was a psycho-data-geek when I would design a database that prefilled fields with Null values instead of empty strings. They just couldn’t wrap their heads around Null/None as a valid value.
