CREATE APPLICATION ROLE (Transact-SQL)
Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance
Adds an application role to the current database.
CREATE APPLICATION ROLE application_role_name WITH PASSWORD = 'password' [ , DEFAULT_SCHEMA = schema_name ]
To view Transact-SQL syntax for SQL Server 2014 and earlier, see Previous versions documentation.
Specifies the name of the application role. This name must not already be used to refer to any principal in the database.
Specifies the password that database users will use to activate the application role. You should always use strong passwords. password must meet the Windows password policy requirements of the computer that is running the instance of SQL Server.
Specifies the first schema that will be searched by the server when it resolves the names of objects for this role. If DEFAULT_SCHEMA is left undefined, the application role will use DBO as its default schema. schema_name can be a schema that does not exist in the database.
Password complexity is checked when application role passwords are set. Applications that invoke application roles must store their passwords. Application role passwords should always be stored encrypted.
Application roles are visible in the sys.database_principals catalog view.
For information about how to use application roles, see Application Roles.
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 APPLICATION ROLE permission on the database.
The following example creates an application role called
weekly_receipts that has the password
Sales as its default schema.
CREATE APPLICATION ROLE weekly_receipts WITH PASSWORD = '987G^bv876sPY)Y5m23' , DEFAULT_SCHEMA = Sales; GO
