I'm trying to compare data values in 2 separate feature classes and find out what has changed.
FCnew | FIELDA (shapefile or feature class)
FCmaster | FIELDA (feature class in a fgdb)
FCnew is periodically being updated by external source - this can have new values or have original values removed.
FCmaster is the master table I manage. This consists of the original FCnew values, and will change periodically from the FCnew.
What I currently do in arcpy is join a master set of objects to FCnew attributes and then truncate FCmaster and append current records.
Now I want to show what has changed as well....ideally saved to a text file.
So all I want to do is compare the 2 fields (FIELDA) and print out what values are different.
I've had a look at table compare etc... but find it hard to just tell me what values have changed from one field.
I was thinking of building dictionaries of each set in arcpy and somehow comparing those lists?
Any help would be greatly appreciated.
Just put me onto the right course....!
