Summary
Each input feature layer or table view will have its workspace modified to connect to the requested version.
Usage
-
Only works with feature layers and table views.
-
The ArcSDE connection file used to create the input feature layer or table view will not be edited by this tool. Only the open workspace of the Feature Layer/Table View is changed to connect to the specified version.
-
Transactional and historical views are supported.
Syntax
ChangeVersion_management (in_features, version_type, {version_name}, {date})
Parameter | Explanation | Data Type |
in_features | The feature layer or table view to connect to using the specified version. | Feature Layer; Table View |
version_type | The type of version to change to.
| String |
version_name (Optional) | Name of the version to change to. Optional if using historical versions. | String |
date (Optional) | Date of the historical version to change to. | Date |
Code sample
ChangeVersion Example (Python Window)
The following Python window script demonstrates how to use the ChangeVersion function in immediate mode.
import arcpy
from arcpy import env
env.workspace = r'c:\Connections\toolbox.sde'
arcpy.MakeFeatureLayer_management(r'TOOLBOX.Redlands\TOOLBOX.street','RedlandsStreets')
arcpy.MakeFeatureLayer_management(r'TOOLBOX.Redlands\TOOLBOX.streams','RedlandsStreams')
arcpy.MakeFeatureLayer_management(arcpy.SelectLayerByLocation_management("RedlandsStreams","WITHIN_A_DISTANCE","RedlandsStreets","100 Meters","NEW_SELECTION",'#'),
'StreamsNearStreets','','','')
arcpy.ChangeVersion_management('RedlandsStreets','TRANSACTIONAL', 'TOOLBOX.proposedStreets2k9','')
arcpy.MakeFeatureLayer_management(arcpy.SelectLayerByLocation_management("RedlandsStreams","WITHIN_A_DISTANCE","RedlandsStreets","100 Meters","NEW_SELECTION",'#'),
'NewStreamsNearStreets','','','')
ChangeVersion example (Stand-alone script)
Use the ChangeVersion tool in a typical versioned analysis workflow.
# Name: ChangeVersion.py
# Description: Use the ChangeVersion tool in a typical versioned analysis workflow.
# Quick check of additional streams within a pre-determined distance
# of new proposed street development.
# Import system modules
import arcpy
import sys
import os
# Set environments
arcpy.env.workspace = sys.path[0] + os.sep + "toolbox.sde"
# Create the layers
arcpy.MakeFeatureLayer_management(r'TOOLBOX.Redlands\TOOLBOX.street','RedlandsStreets')
arcpy.MakeFeatureLayer_management(r'TOOLBOX.Redlands\TOOLBOX.streams','RedlandsStreams')
# Perform analysis on the Default version to determine
# current number of streams within 100 meters of streets.
selection1 = arcpy.SelectLayerByLocation_management("RedlandsStreams",
"WITHIN_A_DISTANCE",
"RedlandsStreets",
"100 Meters",
"NEW_SELECTION",
'#')
arcpy.MakeFeatureLayer_management(selection1,'StreamsNearStreets','','','')
print("Streams within 100 Meters of current streets: {}".format(
arcpy.GetCount_management("StreamsNearStreets")[0]))
# Change to the development version
arcpy.ChangeVersion_management('RedlandsStreets',
'TRANSACTIONAL',
'TOOLBOX.proposedStreets2k9',
'')
# Perform the same analysis on the development version to see the effect of the proposed changes.
selection2 = arcpy.SelectLayerByLocation_management("RedlandsStreams",
"WITHIN_A_DISTANCE",
"RedlandsStreets",
"100 Meters",
"NEW_SELECTION",
'#')
arcpy.MakeFeatureLayer_management(selection2,'NewStreamsNearStreets','','','')
print("Streams projected to be within 100 Meters of streets after proposed street additions: {}".format(
arcpy.GetCount_management("NewStreamsNearStreets")[0]))
