备注

If you are using digest delivery and you want to use a notification field to group messages, set DigestGrouping to true. For example, if a flight application sends notifications for multiple carriers, you can set DigestGrouping to true on the Carrier field so that the notifications for a carrier 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 2005 Notification Services will group messages within a notification batch that have the same SubscriberId, DeviceName, and SubscriberLocale values.

ms145287.note(zh-cn,SQL.90).gif重要提示:
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.

示例

The following example shows a DigestGrouping element set to true to indicate that the application uses the StockSymbol field to determine whether to group individual notifications together for digest delivery.

<Field>
    <FieldName>StockSymbol</FieldName>
    <FieldType>char(10)</FieldType>
    <DigestGrouping>true</DigestGrouping>
</Field>
