Hinweise

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

Alle öffentlichen, statischen Elemente dieses Typs (Shared in Microsoft Visual Basic) sind für Vorgänge mit mehreren Threads sicher. Bei Instanzmembern ist die Threadsicherheit nicht gewährleistet.
