arcpy.da.Editor - RuntimeError: start edit session

[JakeSkinner]

Hello,

ArcGIS 10.4.1

SQL Server 2014

I’m trying to update a versioned feature class within an enterprise geodatabase with the following script:

import arcpy
from arcpy import env
env.workspace = r"D:\Data\GIS.sde"

fc = "Util_SW_outfall"
 
# Start an edit session
edit = arcpy.da.Editor(env.workspace)

# Change second parameter to True for versioned data
edit.startEditing(False, True)
edit.startOperation()

# Update field
with arcpy.da.UpdateCursor(fc, ['County']) as cursor:
    for row in cursor:
        row[0] = 'test'
        cursor.updateRow(row)

# Stop Edit Session
edit.stopOperation()
edit.stopEditing(True)

del cursor‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

However, I receive the following error:

Traceback (most recent call last):

  File "<string>", line 254, in run_nodebug

  File "<module1>", line 21, in <module>

RuntimeError: start edit session

I was able to get the above to work with a File Geodatabase feature class.  I feel like my turkey coma is allowing me to miss something simple, but can’t figure it out.  Anyone have any suggestions?

I have a very similar problem, but the script works when running alone, it has the exactly behavior as yours when running inside a python tool box. Reading your explanation about get it done with gdb at least give me some hope, thanks. But I am very frustrated with the impossibility of using a sde connection correctly, probably I have to change my map service to a gdb now, instead of my microsoft sql table. Somebody knows if it is a reported bug (I'm using 10.3.1) or we are just missing something?
