ArcMap

创建角色

描述

用于创建数据库角色，并且允许您向角色中添加用户或从角色中移除用户。

使用方法

  • 该工具仅适用于 Oracle、Microsoft SQL Server 或 PostgreSQL。

  • 指定角色时不能使用双引号等定界符。 因此，在不提供定界符的情况下，角色仅能包含基础数据库管理系统支持的字符。

语法

arcpy.management.CreateRole(input_database, role, {grant_revoke}, {user_name})
参数说明数据类型
input_database

到数据库或企业级地理数据库的连接文件。 数据库管理员用户的身份进行连接。

Workspace
role

要创建的数据库角色的名称。 如果角色已存在，请输入要为其添加用户或移除用户的角色的名称。

String
grant_revoke
（可选）

指定是将角色添加到用户或用户列表，还是从角色中移除用户或用户列表。

  • GRANT —将角色授予给指定用户，从而使用户成为角色的成员。 这是默认设置。
  • REVOKE —撤销授予给指定用户的角色，从而将其从角色中移除。
String
user_name
（可选）

要更改角色成员资格的用户的名称。 要指定多个用户，请输入以逗号分隔的用户名（无空格）。

String

派生输出

名称说明数据类型
out_result

工具是否成功执行。

Boolean

代码示例

CreateRole 示例 1（Python 窗口）

创建名为 editor 的数据库角色。

import arcpy
arcpy.CreateRole_management("C:\\gdbconnections\\gdb_oracle.sde", "editors")
CreateRole 示例 2（Python 窗口）

创建数据库组角色 drafters 并将其授予给用户 eng1 和 eng2。

import arcpy
arcpy.CreateRole_management("C:\\dbconnections\\db_postg.sde", "drafters", 
                            "GRANT", "eng1,eng2")
CreateRole 示例 3（Python 窗口）

将现有数据库角色 readers 授予用户 auditor。

import arcpy
arcpy.CreateRole_management("C:\\connectionfiles\\db_ss.sde", "readers", 
                            "GRANT", "auditor")
CreateRole 示例 4（Python 窗口）

从数据库用户 intern1、intern2 和 intern3 撤销数据库角色（创建者）。

import arcpy
arcpy.CreateRole_management("D:\\myconnectionfiles\\mygdb.sde", "creators", 
                            "REVOKE", "intern1,intern2,intern3")
CreateRole 示例 5（独立脚本）

以下独立脚本可以提供特定于使用选项的站点的信息：

  • 创建用作 input_database 的数据库连接文件。
  • 创建数据库角色。
  • 将用户添加到新角色。
