在 SQL Server 中编写企业级地理数据库升级脚本

可以修改和使用在本主题中提供的其中一个 Python 脚本来连接和升级企业级地理数据库。

第一个脚本使用现有数据库连接文件来连接和升级地理数据库。

第二个脚本显示如何能够在用于升级地理数据库的相同脚本中提供连接信息。此脚本在您无法访问 ArcGIS for Desktop 时特别有用;您可以在安装了具有 Geodatabase Update 扩展模块的 ArcGIS Engine Runtime 或 ArcGIS for Server Enterprise(Standard 或 Advanced)的计算机上运行 Python 脚本、提供连接信息和升级地理数据库。

无论是使用现有数据库连接文件还是通过脚本中的参数,您所建立的与地理数据库之间的连接都是直连。运行脚本的计算机上必须有以下内容:

请确保升级之前已经阅读和执行过升级 SQL Server 中的地理数据库的准备工作中的步骤。

步骤:
  1. 将这些脚本之一复制到 ArcGIS for Desktop 中的 Python 窗口或任何 Python IDE(如 PythonWin 或 WING)。更改任何变量值来与您的站点信息相匹配。
    • 如果现有数据库连接文件使用直连并以地理数据库管理员(或 sysadmin 用户)的身份进行连接,则复制和修改以下脚本:
      # Name: upgradesdegdb_example.py
      # Description: Connect from a Windows computer 
      # with an existing database connection file 
      # and upgrade an enterprise geodatabase in SQL Server
      # Author: Esri
      
      # Import arcpy module
      import arcpy

      # Process: Upgrade Geodatabase
      arcpy.UpgradeGDB_management(Default_gdb, "PREREQUISITE_CHECK", "UPGRADE")
      
    • 如果计算机上没有用于编写升级脚本的数据库连接文件,则可复制和修改以下脚本:
