CREATE APPLICATION ROLE (Transact-SQL)

  • Άρθρο

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance

Adds an application role to the current database.

Transact-SQL syntax conventions

Syntax

  
CREATE APPLICATION ROLE application_role_name   
    WITH PASSWORD = 'password' [ , DEFAULT_SCHEMA = schema_name ]

Arguments

application_role_name
Specifies the name of the application role. This name must not already be used to refer to any principal in the database.

PASSWORD ='password'
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.

DEFAULT_SCHEMA =schema_name
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.

Remarks

Important

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.

Note

Schemas aren't equivalent to database users. Use System catalog views to identify any differences between database users and schemas.

Permissions

Requires ALTER ANY APPLICATION ROLE permission on the database.

Examples

The following example creates an application role called weekly_receipts that has the password 987Gbv876sPYY5m23 and Sales as its default schema.

CREATE APPLICATION ROLE weekly_receipts   
    WITH PASSWORD = '987G^bv876sPY)Y5m23'   
    , DEFAULT_SCHEMA = Sales;  
GO
