创建数据库用户 (Data Management)

许可等级:BasicStandardAdvanced

摘要

创建数据库用户工具用于在数据库中创建具有足够权限可创建数据的数据库用户。

用法

语法

CreateDatabaseUser_management (input_database, {user_authentication_type}, user_name, {user_password}, {role}, {tablespace_name})
参数说明数据类型
input_database

指定 Oracle、PostgreSQL 或 SQL Server 中数据库或企业级地理数据库的连接文件。确保连接文件作为数据库管理员用户连接到数据库。连接到 Oracle 时,您必须以系统用户身份进行连接。

Workspace
user_authentication_type
(可选)

仅当要为其创建数据库用户的操作系统登录存在时,才使用此参数。仅适用于 SQL Server 和 Oracle 数据库。

  • DB创建经数据库验证的用户。这是默认设置。 如果 DBMS 没有配置为允许数据库身份验证,则不要使用此选项。
  • OSA创建经操作系统身份验证的用户。相应的登录必须已存在。 如果 DBMS 没有配置为允许操作系统身份验证,则不要使用此选项。
Boolean
user_name

为新数据库用户输入名称。

如果选择为操作系统登录帐户创建数据库用户,则用户名必须与登录名匹配。

String
user_password
(可选)

为新用户输入密码。将强制实施基础数据库的密码策略。

如果选择为操作系统登录创建数据库用户,则不需要输入。

Encrypted String
role
(可选)

如果要将新用户添加到现有数据库角色,则输入角色名称。

String
tablespace_name
(可选)

在 Oracle 数据库中创建用户时,输入要用作用户的默认表空间的表空间名称。可指定预配置表空间,如果表空间尚不存在,则将在 Oracle 默认存储位置创建大小设置为 400 MB 的表空间。如果未指定表空间,则用户的默认表空间将设置为 Oracle 默认表空间。

String

代码实例

创建用户 (CreateUser) 示例 1

在 Oracle 中创建数据库用户并为用户创建默认表空间

#Import arcpy module
import arcpy

CreateDatabaseUser_management("C:\Documents and Settings\user1\Application Data\ESRI\ArcCatalog\oracledb1.sde", "DB", "map", "Pam987", "sdetbs")
创建用户 (CreateUser) 示例 2

在 PostgreSQL 中创建输入工作空间和数据库用户

#Import arcpy module
import arcpy

CreateDatabaseConnection_management("Database Connections", "pgconn.sde", "POSTGRESQL", myserver, mypgdb, "DATABASE_AUTH", "ela", "3L@pwd", "SAVE_USERNAME")

CreateDatabaseUser_management("C:\Documents and Settings\u5\Application Data\ESRI\ArcCatalog\pgconn.sde", "DB", "dataowner", "N0look")
创建用户 (CreateUser) 示例 3

在 SQL Server 中创建映射到现有操作系统登录的数据库用户

#Import arcpy module
import arcpy

CreateDatabaseUser_management("C:\Documents and Settings\u5\Application Data\ESRI\ArcCatalog\connection_ssi.sde", "OSA", "mynet\vorhoos", "", "")
创建用户 (CreateUser) 示例 4

用于创建数据库用户的独立脚本
