ALTER ROLE (Transact-SQL)

Changes the name of a database role.

Topic link icon Transact-SQL Syntax Conventions


ALTER ROLE role_name WITH NAME = new_name

role_name

Is the name of the role to be changed.

WITH NAME =new_name

Specifies the new name of the role. This name must not already exist in the database.

Changing the name of a database role does not change ID number, owner, or permissions of the role.

Database roles are visible in the sys.database_role_members and sys.database_principals catalog views.

Caution noteCaution

Beginning with SQL Server 2005, the behavior of schemas changed. As a result, code that assumes that schemas are equivalent to database users may no longer return correct results. Old catalog views, including sysobjects, should not be used in a database in which any of the following DDL statements have ever been used: CREATE SCHEMA, ALTER SCHEMA, DROP SCHEMA, CREATE USER, ALTER USER, DROP USER, CREATE ROLE, ALTER ROLE, DROP ROLE, CREATE APPROLE, ALTER APPROLE, DROP APPROLE, ALTER AUTHORIZATION. In such databases you must instead use the new catalog views. The new catalog views take into account the separation of principals and schemas that was introduced in SQL Server 2005. For more information about catalog views, see Catalog Views (Transact-SQL).

Requires ALTER ANY ROLE permission on the database, or ALTER permission on the role, or membership in the db_securityadmin.

The following example changes the name of role buyers to purchasing.

USE AdventureWorks2008R2;
ALTER ROLE buyers WITH NAME = purchasing;
GO
