# Compare lastModified property of each version to current date, and 
#  print version name if the version was modified in the last 7 days.

    # Delete any versions owned by "RJones" that don't have any children
    #
    if version.name.split(".")[0] == "RJones" and not version.children:
        print("Deleting version {0}".format(version.name))
        arcpy.DeleteVersion_management(sdeConnection, version.name)
ListVersions 示例 3

协调并提交具有特定说明的版本。本示例将使用启用了版本管理功能的要素服务。

# Import system modules import arcpy
# Sign into ArcGIS Enterprise arcpy.SignInToPortal("https://myserver.mydomain.com/portal", 'portaladmin',                      'my.password')
# Create a variable for the feature service URL myFS = "https://myserver.mydomain.com/server/rest/services/BranchVersioningData/FeatureServer"
# Use the ListVersions function to get a list of versions versions = arcpy.da.ListVersions(myFS)
# Create a list of version to reconcile listToRec = []
# For each version in the list, append only those that have the "READY TO POST" 
# description for version in versions:
    if "READY FOR POST" in version.description.upper():
        listToRec.append(version.name)        
# Reconcile and post the versions arcpy.ReconcileVersions_management(myFS,
                                   'ALL_VERSIONS',                                   'sde.DEFAULT',                                   listToRec,                                   'NO_LOCK_ACQUIRED',                                   'ABORT_CONFLICTS',                                   'BY_OBJECT',                                   'FAVOR_EDIT_VERSION',                                   'POST',                                   'KEEP_VERSION')
