备注

Field names can contain letters, numbers, and the special characters _, #, @, and $. They must also conform to Microsoft SQL Server identifier conventions. For more information about SQL Server identifiers, see 标识符.

SQL Server 2005 Notification Services reserves the following field names. Do not create notification fields with these names:

• DeliveryChannelName
• DeliveryStatusCode
• DeviceAddress
• DeviceName
• DeviceTypeName
• DistributorWorkItemId
• ExpirationTime
• LinkNotificationId
• NotificationId
• NotificationBatchId
• SentTime
• SubscriberId
• SubscriberLocale

重要提示：
If you update a FieldName element, updating the application deletes and re-creates the notification class to which it corresponds. This includes dropping and re-creating the SQL Server tables used by this notification class. Any data existing in the original notification class tables is permanently deleted.

示例

The following example shows a FieldName element.

<FieldName>StockPrice</FieldName>
