GRANT Asymmetric Key Permissions (Transact-SQL)

Syntax

GRANT { permission  [ ,...n ] } 
    ON ASYMMETRIC KEY ::asymmetric_key_name 
       TO database_principal [ ,...n ]
    [ WITH GRANT OPTION ]
    [ AS granting_principal ]

Arguments

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

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

• database_principal
  Specifies the principal to which the permission is being granted. 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.

• GRANT OPTION
  Indicates that the principal will also be given the ability to grant the specified permission to other principals.

• AS granting_principal
  Specifies a principal from which the principal executing this query derives its right to grant 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.

Permissions

The grantor (or the principal specified with the AS option) must have either the permission itself with GRANT OPTION, or a higher permission that implies the permission being granted.

If using the AS option, these additional requirements apply.

Object owners can grant permissions on the objects they own. Principals with CONTROL permission on a securable can grant permission on that securable.

Grantees of CONTROL SERVER permission, such as members of the sysadmin fixed server role, can grant any permission on any securable in the server. Grantees of CONTROL permission on a database, such as members of the db_owner fixed database role, can grant any permission on any securable in the database. Grantees of CONTROL permission on a schema can grant any permission on any object within the schema.
