Create Role (Data Management)—ArcGIS Pro

Summary

Creates a database role, allowing you to add users to or remove them from the role.

Usage

This tool can be used with Oracle, Microsoft SQL Server, or PostgreSQL only.
You cannot use delimiters, such as double quotation marks, when specifying the role. 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 to create. If it's an existing role, type the name for the role you want to add users to or remove them from.	String
grant_revoke (Optional)	Specifies whether the role will be added to a user or list of users or a user or list of users will be removed from the role. GRANT —The role will be granted to the specified user or users, making them a member of the role. This is the default.

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")
