Create Database User

Summary

Creates a database user with privileges sufficient to create data in the database.

Usage

• This tool can be used only with Oracle, Microsoft SQL Server, or PostgreSQL. This tool is not supported with cloud database services.

• For Oracle and SQL Server, if an operating system login already exists, the Create Database User tool can add that login as a user to the specified database.

• You cannot create a database user for a Windows group.

• This tool creates shared log file tables for the user when run on a geodatabase in Oracle.

• Users created in the database have the following privileges granted to them:

  DBMS	Privileges
  Oracle	CREATE PROCEDURE CREATE SESSION CREATE SEQUENCE CREATE TABLE CREATE TRIGGER CREATE VIEW SELECT ON DBA_ROLES
  PostgreSQL	CONNECT TEMPORARY USAGE on the sde schema if the user is created in a geodatabase or a database that has the ST_Geometry type installed SELECT, INSERT, UPDATE, and DELETE on the geometry_columns and geography_columns views and SELECT on the spatial_ref_sys view if PostGIS is installed in the database
  SQL Server	CREATE TABLE CREATE PROCEDURE CREATE VIEW

• If the login does not exist in the SQL Server instance or PostgreSQL database cluster, the Create Database User tool adds the login, creates a user in the database specified for the Input Database Connection, and creates a schema for the user in the database. The specified database is set as the user's default database in SQL Server.

• If the login already exists in the SQL Server instance, the Create Database User tool adds the user to the database specified for the Input Database Connection and creates a matching schema. The user's default database is not changed in SQL Server.

• If the login already exists in the PostgreSQL database cluster, the Create Database User tool creates a matching schema in the database specified for the Input Database Connection.

• You cannot create a user named sde with this tool. The sde user is a geodatabase administrator user and requires more privileges than the Create Database User tool grants.

• You cannot use delimiters, such as double quotation marks, when specifying a user name. The user name can only contain characters supported by the underlying database management system when provided without delimiters.

Syntax

arcpy.management.CreateDatabaseUser(input_database, {user_authentication_type}, user_name, {user_password}, {role}, {tablespace_name})

Parameter	Explanation	Data Type
input_database	Specify the connection file to a database or enterprise geodatabase in Oracle, PostgreSQL, or SQL Server. Be sure that the connection is made as a database administrator user. When connecting to Oracle, you must connect as the sys user.	Workspace
user_authentication_type (Optional)	Specify the authentication type for the user. If you specify OPERATING_SYSTEM_USER, an operating system login must already exist for the user you want to create. Operating system users are only supported for SQL Server and Oracle databases. DATABASE_USER —Create a database-authenticated user. This is the default. If your database management system is not configured to allow database authentication, do not use this option. OPERATING_SYSTEM_USER —Create an operating system-authenticated user. The corresponding login must already exist. If your database management system is not configured to allow operating system authentication, do not use this option.	Boolean
user_name	Type a name for the new database user. If you chose to create a database user for an operating system login, the user name must match the login name.	String
user_password (Optional)	Type a password for the new user. The password policy of the underlying database is enforced. If you chose to create a database user for an operating system login, no input is required.	Encrypted String
role (Optional)	If you want to add the new user to an existing database role, specify the name of the role.	String
tablespace_name (Optional)	When creating a user in an Oracle database, type the name of the tablespace to be used as the default tablespace for the user. You can specify a preconfigured tablespace, or, if the tablespace does not already exist, it will be created in the Oracle default storage location with its size set to 400 MB. If no tablespace is specified, the user's default tablespace will be set to the Oracle default tablespace.	String

Derived Output

Name	Explanation	Data Type
out_result	Whether the tool completed successfully.	Boolean

Code sample

CreateDatabaseUser example 1 (Python window)

Sample script uses a predefined database connection file (oracledb1.sde) to create a database user in Oracle, and creates a default tablespace (sdetbs) for the user.

import arcpy
arcpy.CreateDatabaseUser_management("C:/myconnections/oracledb1.sde", 
                                    "DATABASE_USER", "map", "Pam987", "sdetbs")

CreateDatabaseUser example 2 (Python window)

Sample script creates an input workspace (pgconn.sde) in a folder named connections, and creates a database login role and schema in PostgreSQL.

import arcpy
arcpy.CreateDatabaseConnection_management("C:/connections", "pgconn.sde", 
                                          "POSTGRESQL", myserver, mypgdb, 
                                          "DATABASE_AUTH", "ela", "3L@pwd", 
                                          "SAVE_USERNAME")
arcpy.CreateDatabaseUser_management("C:/connections/pgconn.sde", 
                                    "DATABASE_USER", "dataowner", "N0look")

CreateDatabaseUser example 3 (Python window)

Sample script creates a database user mapped to an existing operating system login (mynet\vorhoos) in SQL Server and uses a predefined database connection file (connection_ssi.sde).

import arcpy
arcpy.CreateDatabaseUser_management("C:/gdbconnections/connection_ssi.sde", 
                                    "OPERATING_SYSTEM_USER", "mynet\\vorhoos")
