Is there a doc anywhere that talks about when a field is Null and when it is Empty string?
It my testing I have seen that for a Hosted Feature Service if a user leaves a field blank, or if it is not relevant, it it gets empty string. This is true even for Int/Dec which is not possible in most Arc. But when you download that data to a GDB int and decimal convert to Null, but strings stay empty string. Dates not sure yet.
For now I have been adding code to my scripts to check for both "" and Null.
I want to make sure I know the pattern correctly. Will there ever be a way to have strings be Null? Or would this need to be post processing to match our legacy data.
