Summary

The Create Role tool creates a database role and lets you add users to or remove users from the role.

Usage

This tool can only be used with Oracle, Microsoft SQL Server, or PostgreSQL.
You cannot use delimeters, such as double-quote marks, when specifying the role. Therefore, the role can only contain characters supported by the underlying database management system when provided without delimeters.

Syntax

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

Parameter	Explanation	Data Type
input_database	Specify the connection file to a database or enterprise geodatabase. You must use a direct connection (not an ArcSDE service), and connect as a database administrator user.	Workspace
role	Type the name of the database role you want to create. If the role already exists, type the name of the role for which you want to add users or remove users.	String
grant_revoke (Optional)	Specify whether to grant the role to a user or list of users or remove a user or list of users from the role. GRANT —Grants the role to the specified user or users, thereby making them a member of the role REVOKE —Revokes the role from the specified user or users, thereby removing them from the role	String
user_name (Optional)	Type the name of the user for which you want to change role membership. To specify multiple users, type the user names separated by commas (no spaces).	String

Code sample

CreateRole example 1

Creates a database role, editors, in a geodatabase in Oracle.

arcpy.CreateRole_management("C:\\gdbconnections\\gdb_oracle.sde", "editors")

CreateRole example 2

Creates a database group role, drafters, in a PostgreSQL database cluster and grants it to users eng1 and eng2.

#Import arcpy module
import arcpy

arcpy.CreateRole_management("C:\\dbconnections\\db_postg.sde", "drafters", "GRANT", "eng1,eng2")

CreateRole example 3

Grants an existing database role, readers, to user auditor in a SQL Server database.

#Import arcpy module
import arcpy

arcpy.CreateRole_management("C:\\connectionfiles\\db_ss.sde", "readers", "GRANT", "auditor")

CreateRole example 4

Revokes the database role, creators, from database users intern1, intern2, and intern3.

#Import arcpy module
import arcpy

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

CreateRole example 5

The following stand-alone script allows you to provide information specific to your site using options to:

Create a database connection file, which is used as the input_database.
Create a database role.
Add users to the new role.
