Create Role

Summary

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 delimiters, 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 delimiters.

Syntax

arcpy.management.CreateRole(input_database, role, {grant_revoke}, {user_name})

Parameter	Explanation	Data Type
input_database	The connection file to a database or enterprise geodatabase. Connect as a database administrator user.	Workspace
role	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)	Specifies whether to add 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. This is the default. REVOKE —Revokes the role from the specified user or users, thereby removing them from the role.	String
user_name (Optional)	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

Derived Output

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

Code sample

CreateRole example 1 (Python window)

Creates a database role named editors.

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

CreateRole example 2 (Python window)

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

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

CreateRole example 3 (Python window)

Grants an existing database role, readers, to user auditor.

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

CreateRole example 4 (Python window)

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

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

CreateRole example 5 (stand-alone script)

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.
