How do I delete a feature from a ArcGIS for Server Feature server using arcpy?

Question asked by shawnkeizer on May 18, 2018

I have a feature service created using ArcGIS for Server and using python i want to select feature(s) based on OBJECTID and delete them. The user will be selecting the features to delete in Arcmap. I know i am able to create a local copy, delete them manualy and sync back to the service but i want to do all the lifting via python. Any help would be appreciated.


Below is what i have so far the section "Choose orginal features to delete" is what i can not get working, the rest of the code works fine.

# List selected data...

for row in cursor:
del cursor

# Delete features that were not selected...

for sel in selFeat:
sql += 'OBJECTID = ' + str(sel) + ' OR '
arcpy.SelectLayerByAttribute_management(out_name, selection_type='NEW_SELECTION', where_clause=sql[:-4])
arcpy.SelectLayerByAttribute_management(out_name, selection_type='SWITCH_SELECTION')

del row
del Cursor

#Stop/save edits
print "Stopping editing"
arcpy.SelectLayerByAttribute_management(in_layer_or_view=inLyr, selection_type='CLEAR_SELECTION')

arcpy.AddMessage('\n... Finished coping features :)\n')
