In ArcGIS 10, is there a way to add a field to a feature class even if it currently contains data?

To do this programmatically, use IClass.AddField. (Do NOT use IFieldsEdit.AddField on an existing dataset). |

In Python, using the ArcPy site package, you'd use arcpy.AddField_management(.....) You cannot modify the actual field name of an existing field. I would LOVE to be able to do that, but even if they implement it, I bet it'll be similar to renaming in SQL. That is, the net effect is a renamed field, but the underlying operation is: make new field with new field name, copy contents from old field, drop old field name. |
