주의

Field names must start with a letter or underscore character and can contain letters, numbers, and the characters _, #, @ and $. They must also conform to Microsoft SQL Server identifier conventions. For more information about SQL Server identifiers, see 식별자.

중요:
You cannot name a subscription field Created, Enabled, SubscriberId, SubscriptionId, or Updated. SQL Server 2005 Notification Services already uses these field names internally.

If you update a FieldName element, updating the application re-creates the subscription class to which it corresponds. A new subscription table is created, and the existing subscription table is renamed to SubscriptionTableNameOld. 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 응용 프로그램 업데이트.
