備註

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.
