Remarks

Database User Permissions

A database user 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 database user are listed in the following table, together with the more general permissions that include them by implication.

Database user permission Implied by database user permission Implied by database permission
CONTROL CONTROL CONTROL
IMPERSONATE CONTROL CONTROL
ALTER CONTROL ALTER ANY USER
VIEW DEFINITION CONTROL VIEW DEFINITION

Database Role Permissions

A database role 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 database role are listed in the following table, together with the more general permissions that include them by implication.

Database role permission Implied by database role permission Implied by database permission
CONTROL CONTROL CONTROL
TAKE OWNERSHIP CONTROL CONTROL
ALTER CONTROL ALTER ANY ROLE
VIEW DEFINITION CONTROL VIEW DEFINITION

Application Role Permissions

An application role 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 an application role are listed in the following table, together with the more general permissions that include them by implication.

Application role permission Implied by application role permission Implied by database permission
CONTROL CONTROL CONTROL
ALTER CONTROL ALTER ANY APPLICATION ROLE
VIEW DEFINITION CONTROL VIEW DEFINITION

Permissions

Requires CONTROL permission on the specified principal, or a higher permission that implies CONTROL permission.

Grantees of CONTROL permission on a database, such as members of the db_owner fixed database role, can deny any permission on any securable in the database.

Examples

A. Denying CONTROL permission on a user to another user

The following example denies CONTROL permission on the AdventureWorks2012 user Wanida to user RolandX.

USE AdventureWorks2012;  
DENY CONTROL ON USER::Wanida TO RolandX;  
GO  

B. Denying VIEW DEFINITION permission on a role to a user to which it was granted with GRANT OPTION

The following example denies VIEW DEFINITION permission on the AdventureWorks2012 role SammamishParking to database user JinghaoLiu. The CASCADE option is specified because user JinghaoLiu was granted VIEW DEFINITION permission WITH GRANT OPTION.

USE AdventureWorks2012;  
DENY VIEW DEFINITION ON ROLE::SammamishParking   
    TO JinghaoLiu CASCADE;  
GO  

C. Denying IMPERSONATE permission on a user to an application role

The following example denies IMPERSONATE permission on user HamithaL to the AdventureWorks2012 application role AccountsPayable17.

||
|-|
|Applies to: SQL Server 2008 through SQL Server 2016, SQL Database.|

USE AdventureWorks2012;  
DENY IMPERSONATE ON USER::HamithaL TO AccountsPayable17;  
GO
