Замечания
Credentials provide SQL Server authenticated users with an identity outside of SQL Server, on the local machine or on the network domain.
Credentials can also be used when a SQL Server authenticated user needs access to a domain resource, such as a file location to store a backup.
To get Credential object properties, users can be a member of the public fixed server role.
To set Credential object properties and run the Alter method, users must have ALTER ANY CREDENTIAL permission on the parent server, or be a member of the sysadmin fixed server role.
To create a credential, users must have ALTER ANY CREDENTIAL permission on the parent server, or be a member of the sysadmin fixed server role.
To drop a credential, users must have ALTER ANY CREDENTIAL permission on the parent server, or be a member of the sysadmin fixed server role.
Thread Safety
Все общие статические члены этого типа (Shared в Microsoft Visual Basic) можно использовать в многопоточных операциях. Потокобезопасная работа с членами экземпляров типа не гарантируется.
Безопасность многопоточности
Любые открытые статический (Shared в Visual Basic) элементы этого типа потокобезопасны. Потокобезопасность с элементами экземпляров не гарантируется.
