Arguments

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

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

• TO <server_principal>
  Specifies the principal to which the permission is denied.

• AS <grantor_principal>
  Specifies the principal from which the principal executing this query derives its right to deny the permission.

• SQL_Server_login
  Specifies a SQL Server login.

• SQL_Server_login_mapped_to_Windows_login
  Specifies a SQL Server login mapped to a Windows login.

• SQL_Server_login_mapped_to_Windows_group
  Specifies a SQL Server login mapped to a Windows group.

• SQL_Server_login_mapped_to_certificate
  Specifies a SQL Server login mapped to a certificate.

• SQL_Server_login_mapped_to_asymmetric_key
  Specifies a SQL Server login mapped to an asymmetric key.

• server_role
  Specifies a server role.

Remarks

Permissions at the server scope can be denied only when the current database is master.

Information about server permissions can be viewed in the sys.server_permissions catalog view, and information about server principals can be viewed in the sys.server_principals catalog view. Information about membership of server roles can be viewed in the sys.server_role_members catalog view.

A server is the highest level of the permissions hierarchy. The most specific and limited permissions that can be denies on a server are listed in the following table.

Server permission	Implied by server permission
ADMINISTER BULK OPERATIONS	CONTROL SERVER
ALTER ANY AVAILABILITY GROUP	CONTROL SERVER
ALTER ANY CONNECTION	CONTROL SERVER
ALTER ANY CREDENTIAL	CONTROL SERVER
ALTER ANY DATABASE	CONTROL SERVER
ALTER ANY ENDPOINT	CONTROL SERVER
ALTER ANY EVENT NOTIFICATION	CONTROL SERVER
ALTER ANY EVENT SESSION	CONTROL SERVER
ALTER ANY LINKED SERVER	CONTROL SERVER
ALTER ANY LOGIN	CONTROL SERVER
ALTER ANY SERVER AUDIT	CONTROL SERVER
ALTER ANY SERVER ROLE	CONTROL SERVER
ALTER RESOURCES	CONTROL SERVER
ALTER SERVER STATE	CONTROL SERVER
ALTER SETTINGS	CONTROL SERVER
ALTER TRACE	CONTROL SERVER
AUTHENTICATE SERVER	CONTROL SERVER
CONNECT SQL	CONTROL SERVER
CONTROL SERVER	CONTROL SERVER
CREATE ANY DATABASE	ALTER ANY DATABASE
CREATE ANY AVAILABILITY GROUP	ALTER ANY AVAILABILITY GROUP
CREATE DDL EVENT NOTIFICATION	ALTER ANY EVENT NOTIFICATION
CREATE ENDPOINT	ALTER ANY ENDPOINT
CREATE TRACE EVENT NOTIFICATION	ALTER ANY EVENT NOTIFICATION
EXTERNAL ACCESS ASSEMBLY	CONTROL SERVER
SHUTDOWN	CONTROL SERVER
UNSAFE ASSEMBLY	CONTROL SERVER
VIEW ANY DATABASE	VIEW ANY DEFINITION
VIEW ANY DEFINITION	CONTROL SERVER
VIEW SERVER STATE	ALTER SERVER STATE

Permissions

Requires CONTROL SERVER permission or ownership of the securable. If you use the AS clause, the specified principal must own the securable on which permissions are being denied.

Examples

A. Denying CONNECT SQL permission to a SQL Server login and principals to which the login has regranted it

The following example denies CONNECT SQL permission to the SQL Server login Annika and to the principals to which she has granted the permission.

USE master;
DENY CONNECT SQL TO Annika CASCADE;
GO

B. Denying CREATE ENDPOINT permission to a SQL Server login using the AS option

The following example denies CREATE ENDPOINT permission to the user ArifS. The example uses the AS option to specify MandarP as the principal from which the executing principal derives the authority to do so.

USE master;
DENY CREATE ENDPOINT TO ArifS AS MandarP;
GO
