적용 대상: Microsoft Fabric의 SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics SQL 데이터베이스

개체는 ServerPermission 개체에 사용 권한 집합 또는 개별 서버 권한을 할당하는 ServerPermissionSet 데 사용됩니다. 서버 수준 권한의 경우 피부여자는 로그온을 참조합니다. Windows에서 인증된 로그온은 Windows 사용자 이름으로 나열됩니다. 이 코드 샘플이 실행되면 피부여자의 사용 권한을 취소하고 메서드를 사용하여 EnumServerPermissions 제거되었는지 확인합니다.

DatabasePermissionSet 개체 및 ObjectPermissionSet 개체를 사용하여 비슷한 방법으로 데이터베이스 권한 및 데이터베이스 개체 권한을 할당할 수 있습니다.

예시

제공된 코드 예제를 사용하려면 프로그래밍 환경, 프로그래밍 템플릿 및 애플리케이션을 만들 프로그래밍 언어를 선택해야 합니다. 자세한 내용은 Visual Studio .NET에서 Visual C# SMO 프로젝트 만들기를 참조하세요.

Visual Basic에서 서버 사용 권한 부여

이 코드 예제는 지정된 로그인에 Create Endpoint 및 Alter Any Endpoint 권한을 부여한 다음, 권한을 열거하고 표시합니다. 사용 권한 중 하나가 해지된 다음 사용 권한이 다시 열거됩니다. 이 예제에서는 지정된 로그인에 시작할 지정된 권한이 있다고 가정합니다.
