屬性值
型別：System.String
A String value that specifies the name of the pull subscription.
備註
The Name property can only be retrieved by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.
Retrieving the Name property is equivalent to executing sp_helppullsubscription (Transact-SQL) or sp_helpmergepullsubscription (Transact-SQL).
