ListVersions

摘要

列出工作空间中的数据版本。

说明

可以指定连接文件的路径或者要素服务 URL 作为函数的参数，或者将工作空间环境设置为连接文件或要素服务 URL，并调用不带任何参数的 ListVersions 函数。

注：

不能将 arcpy.da.ListVersions 函数与 arcpy.ListVersions 函数相混淆，后者用于返回一个已连接用户有权使用的版本名称列表。

语法

ListVersions (sde_workspace)

参数	说明	数据类型
sde_workspace	An enterprise geodatabase workspace or a feature service with version management capability enabled.	String

返回值

数据类型	说明
Version	Version 对象的列表。

代码示例

ListVersions 示例 1

识别上周修改的所有数据库版本。

import arcpy
import datetime

# Use datetime to establish current date/time
now = datetime.datetime.now()

sdeConnection = "C:/MyProject/toolboxDEFAULTVersion.sde"

# Compare lastModified property of each version to current date, and 
#  print version name if the version was modified in the last 7 days.
for version in arcpy.da.ListVersions(sdeConnection):
    if (now - version.lastModified).days < 7:
        print(version.name)

ListVersions 示例 2

请删除所有属于特定用户不具有任何子版本的数据库版本。

import arcpy

sdeConnection = "C:/MyProject/toolboxDEFAULTVersion.sde"

for version in arcpy.da.ListVersions(sdeConnection):
    # 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.management.DeleteVersion(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.management.ReconcileVersions(myFS,
                                   'ALL_VERSIONS',
                                   'sde.DEFAULT',
                                   listToRec,
                                   'NO_LOCK_ACQUIRED',
                                   'ABORT_CONFLICTS',
                                   'BY_OBJECT',
                                   'FAVOR_EDIT_VERSION',
                                   'POST',
                                   'KEEP_VERSION')
