I'm using ArcPro 2.2.1
How do I set a date to Null instead of 1/1/1900 in the field calculator of a table in a file geodatabase?
My work around was to do this in 10.4.1 and calculate a set of records to NULL but I'd like to break the habit!
With Python as the expression type, you can calculate to None
That's not such a bad habit; what's wrong with that approach?
You're right...I suppose I have about 4 years to figure this out
I would be remiss it I didn't ask... did it work in PRO 2.2? or was this just since the update today
I tried it before and after the update today.
I had tried none
but not None
Thanks
I'm trying to accomplish the same thing - set the value for a date field to Null. However, I'm using ArcGIS Desktop 10.3, with a file geodatabase feature class stored on my org's network server. I had already tried the answer given here (calculate the field using Python and enter None), but I got the following error: "An unexpected failure occurred. No rows were updated."
When I try to edit the field for an individual feature, there is a drop-down for selecting a date from a calendar. When I try to just delete the field value for one feature, I also get an error. Anyone know how to get around this?
I'm guessing that the field properties do not allow null values. With alter field you should be able to fix it if that's the problem: Alter Field—Help | ArcGIS for Desktop
I thought about this too, but it says "Null values allowed."
I can't enter a valid date for the value either. It may be that I just don't have permission to edit this field or this feature class.
Have you been able to edit this feature class/table in the past? What version of arcgis created the file geodatabase and/or the feature class itself? I can't remember if the sun has set on 10.3; it's gotta be close though.
It' like us Joe... mature
