I have tried to use the UpdateCursor method in ArcGIS Desktop 10 SP1 (standalone python and the python window in arcCatalog) and 9.3.1 (standalone python) on an SDE table. I get errors with any method.
Suggestions? Workarounds? Is this a bug?
EDIT: The Insert Cursor and Search Cursor functions do not cause errors. This is not versioned.
EDIT2: Turns out the SDE table I was prototyping on did not have OIDs. Problem solved 🙂
