備註
Subscription class names must conform to SQL Server identifier naming conventions and must be unique within the application. For more information about SQL Server identifier naming conventions, see 識別碼.
If you update the SubscriptionClassName element, updating the application re-creates the subscription class to which it corresponds. Notification Services renames the existing subscription tables by appending Old to the table name and then creates new tables. Existing subscription table indexes are left unchanged.
If you want to transfer data between the old and new subscription tables, it must be done manually. For more information, see 更新應用程式.
