Замечания
If you want a notification field used to determine if notifications should be grouped when using digest delivery, set DigestGrouping to true. For example, if a calendar application notifies users of future events, you can set DigestGrouping to true on a computed DaysToEvent field so that only notifications for events on the same day are grouped into a single notification.
If you are using digest delivery but you do not set DigestGrouping to true on any fields, Microsoft SQL Server Notification Services will group messages within a notification batch that have the same SubscriberId, DeviceName, and SubscriberLocale values.
If you add, delete, or update a DigestGrouping 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.
Пример
The following example shows a DigestGrouping element set to true to indicate that the associated field should be used when determining whether to group notifications together for digest delivery.
<DigestGrouping>true</DigestGrouping>
