DENY Object Permissions (Transact-SQL)

Denies permissions on a member of the OBJECT class of securables. These are the members of the OBJECT class: tables, views, table-valued functions, stored procedures, extended stored procedures, scalar functions, aggregate functions, service queues, and synonyms.

permission

Specifies a permission that can be denied on a schema-contained object. For a list of the permissions, see the Remarks section later in this topic.

ALL

Denying ALL does not deny all possible permissions. Denying ALL is equivalent to denying all ANSI-92 permissions applicable to the specified object. The meaning of ALL varies as follows:

Scalar function permissions: EXECUTE, REFERENCES.

Table-valued function permissions: DELETE, INSERT, REFERENCES, SELECT, UPDATE.

Stored Procedure permissions: EXECUTE.

Table permissions: DELETE, INSERT, REFERENCES, SELECT, UPDATE.

View permissions: DELETE, INSERT, REFERENCES, SELECT, UPDATE.

PRIVILEGES

Included for ANSI-92 compliance. Does not change the behavior of ALL.

column

Specifies the name of a column in a table, view, or table-valued function on which the permission is being denied. The parentheses ( ) are required. Only SELECT, REFERENCES, and UPDATE permissions can be denied on a column. column can be specified in the permissions clause or after the securable name.

ms173724.Caution(en-US,SQL.90).gifCaution:
In SQL Server 2005 a table-level DENY does not take precedence over a column-level GRANT. This inconsistency in the permissions hierarchy has been preserved for backward compatibility.

ON [ OBJECT :: ] [ schema_name ] . object_name

Specifies the object on which the permission is being denied. The OBJECT phrase is optional if schema_name is specified. If the OBJECT phrase is used, the scope qualifier (::) is required. If schema_name is not specified, the default schema is used. If schema_name is specified, the schema scope qualifier (.) is required.

TO <database_principal>

Specifies the principal to which the permission is being denied.

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 objects is visible in various catalog views. For more information, see Object Catalog Views (Transact-SQL).

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

VIEW DEFINITION

Requires CONTROL permission on the object.

If you use the AS clause, the specified principal must own the object on which permissions are being denied.

A. Denying SELECT permission on a table

The following example denies SELECT permission to the user RosaQdM on the table Person.Address in the AdventureWorks database.

USE AdventureWorks;
DENY SELECT ON OBJECT::Person.Address TO RosaQdM;
GO

B. Denying EXECUTE permission on a stored procedure

The following example denies EXECUTE permission on the stored procedure HumanResources.uspUpdateEmployeeHireInfo to an application role called Recruiting11.

USE AdventureWorks;
DENY EXECUTE ON OBJECT::HumanResources.uspUpdateEmployeeHireInfo
    TO Recruiting11;
GO 

C. Denying REFERENCES permission on a view with CASCADE

The following example denies REFERENCES permission on the column EmployeeID in the view HumanResources.vEmployee to the user Wanida with CASCADE.

USE AdventureWorks;
DENY REFERENCES (EmployeeID) ON OBJECT::HumanResources.vEmployee 
    TO Wanida CASCADE;
GO
