ArcGIS Help 10.2 - 创建角色 (Data Management)

摘要

创建角色工具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。

用法

此工具只能与 Oracle、Microsoft SQL Server 或 PostgreSQL 配合使用。
指定该角色时，无法使用分隔符（例如双引号）。因此，当该角色不使用分隔符时，该角色只能包含基础数据库管理系统支持的字符。

语法

CreateRole_management (input_database, role, {grant_revoke}, {user_name})

参数	说明	数据类型
input_database	指定到数据库或企业级地理数据库的连接文件。必须使用直连（而非 ArcSDE 服务），并且以数据库管理员用户身份进行连接。	Workspace
role	输入要创建的数据库角色的名称。如果此角色已经存在，则请输入您需要添加或删除的用户所用的角色的名称。	String
grant_revoke (可选)	指定是否将角色授予给用户或用户列表，或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 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)	输入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（无空格）分隔的用户名称。	String

代码实例

创建角色 (CreateRole) 示例 1

在 Oracle 地理数据库中创建数据库角色 editors。

CreateRole_management("C:\Documents and Settings\administrator\Application Data\ESRI\ArcCatalog\gdb_oracle.sde", "editors", "", "")

创建角色 (CreateRole) 示例 2

在 PostgreSQL 数据库集群中创建数据库组角色 drafters 并将其授予用户 eng1 和 eng2。

#Import arcpy module
import arcpy

CreateRole_management("C:\Documents and Settings\administrator\Application Data\ESRI\ArcCatalog\db_postg.sde", "drafters", "GRANT", "eng1,eng2")

创建角色 (CreateRole) 示例 3

将现有数据库角色 readers 授予 SQL Server 数据库中的用户 auditor。

#Import arcpy module
import arcpy

CreateRole_management("C:\Documents and Settings\administrator\Application Data\ESRI\ArcCatalog\db_ss.sde", "readers", "GRANT", "auditor")

创建角色 (CreateRole) 示例 4

撤销授予给数据库用户 intern1、intern2 和 intern3 的数据库角色 creators。

#Import arcpy module
import arcpy

CreateRole_management("D:\myconnectionfiles\mygdb.sde", "creators", "REVOKE", "intern1,intern2,intern3")

创建角色 (CreateRole) 示例 5

以下独立脚本可以使用选项提供站点特定的信息，从而
