permission

Specifies a permission that can be denied on a symmetric key. For a list of the permissions, see the Remarks section later in this topic.

ON SYMMETRIC KEY ::asymmetric_key_name

Specifies the symmetric key on which the permission is being denied. The scope qualifier (::) is required.

TO <database_principal>

Specifies the principal from which the permission is being revoked.

CASCADE

Indicates that the permission being denied is also denied to other principals to which it has been granted by this principal.

AS <database_principal>

Specifies a principal from which the principal executing this query derives its right to deny the permission.

Database_user

Specifies a database user.

Database_role

Specifies a database role.

Application_role

Specifies an application role.

Database_user_mapped_to_Windows_User

Specifies a database user mapped to a Windows user.

Database_user_mapped_to_Windows_Group

Specifies a database user mapped to a Windows group.

Database_user_mapped_to_certificate

Specifies a database user mapped to a certificate.

Database_user_mapped_to_asymmetric_key

Specifies a database user mapped to an asymmetric key.

Database_user_with_no_login

Specifies a database user with no corresponding server-level principal.

Information about symmetric keys is visible in the sys.symmetric_keys catalog view.

A symmetric key is a database-level securable contained by the database that is its parent in the permissions hierarchy. The most specific and limited permissions that can be denied on a symmetric key are listed in the following table, together with the more general permissions that include them by implication.

VIEW DEFINITION

Requires CONTROL permission on the symmetric key or ALTER ANY SYMMETRIC KEY permission on the database. If you use the AS option, the specified principal must own the symmetric key.

The following example denies ALTER permission on the symmetric key SamInventory42 to the database user HamidS.

USE AdventureWorks2012;
DENY ALTER ON SYMMETRIC KEY::SamInventory42 TO HamidS;
