注释

To get LinkedServer object properties, users can be a member of the public fixed server role.

To set LinkedServer object properties, users must have ALTER ANY LINKED SERVER permission on the server or be a member of the sysadmin fixed server role.

To create or drop a linked server, users must have ALTER ANY LINKED SERVER permission on the server or be a member of the sysadmin fixed server role.

To enumerate tables or columns on the linked server, users must have SELECT permission on the schema.
