Denies permissions on an asymmetric key.

Transact-SQL Syntax Conventions

Syntax

DENY { permission  [ ,...n ] } 
    ON ASYMMETRIC KEY :: asymmetric_key_name 
        TO database_principal [ ,...n ]
    [ CASCADE ]
        [ AS denying_principal ]

Arguments

• permission
  Specifies a permission that can be denied on an asymmetric key. Listed below.

• ON ASYMMETRIC KEY **::**asymmetric_key_name
  Specifies the asymmetric key on which the permission is being denied. The scope qualifier "::" is required.

• database_principal
  Specifies the principal to which the permission is being denied. One of the following:

  • database user
  • database role
  • application role
  • database user mapped to a Windows login
  • database user mapped to a Windows group
  • database user mapped to a certificate
  • database user mapped to an asymmetric key
  • database user not mapped to a server principal.

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

• denying_principal
  Specifies a principal from which the principal executing this query derives its right to deny the permission. One of the following:

  • database user
  • database role
  • application role
  • database user mapped to a Windows login
  • database user mapped to a Windows group
  • database user mapped to a certificate
  • database user mapped to an asymmetric key
  • database user not mapped to a server principal.

Remarks

An asymmetric 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 granted on an asymmetric key are listed below, together with the more general permissions that include them by implication.

Asymmetric Key permission	Implied by asymmetric key permission	Implied by database permission
CONTROL	CONTROL	CONTROL
TAKE OWNERSHIP	CONTROL	CONTROL
ALTER	CONTROL	ALTER ANY ASYMMETRIC KEY
REFERENCES	CONTROL	REFERENCES
VIEW DEFINITION	CONTROL	VIEW DEFINITION

Permissions

Requires CONTROL permission on the asymmetric key. If the AS clause is used, the specified principal must own the asymmetric key.
