Artikkeli

Gets or sets the digest grouping setting, which specifies if the field is used to determine which notifications are combined into a digest.

Namespace: Microsoft.SqlServer.Management.Nmo
Assembly: Microsoft.SqlServer.Smo (in microsoft.sqlserver.smo.dll)

Syntax

'Declaration
Public Property DigestGrouping As Boolean

public bool DigestGrouping { get; set; }

public:
property bool DigestGrouping {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_DigestGrouping ()

/** @property */
public void set_DigestGrouping (boolean value)

public function get DigestGrouping () : boolean

public function set DigestGrouping (value : boolean)

Property Value

true if the field is used to determine digest grouping; otherwise, false.

Remarks

The DigestGrouping property is optional, and the default value is false.

If you want a field used to determine if notifications should be grouped when using digest delivery, 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, Notification Services groups 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.

Example

The following examples show how to define a notification field that is used to group digest notifications, and then add the field to the collection of notification fields for a notification class:

// Define a LeavingFrom notification field and use it for grouping 
// digest messages. Add it to the end of the field collection
NotificationField notificationOrgin = 
    new NotificationField(flightNotifications, "LeavingFrom");
notificationOrgin.Type = "nvarchar(6)";
notificationOrgin.DigestGrouping = true;
flightNotifications.NotificationFields.Add(notificationOrgin);

' Define a LeavingFrom field and use it for grouping
' digest messages. Add it to the end of the collection.
Dim notificationOrgin As NotificationField = _
    New NotificationField(flightNotifications, "LeavingFrom")
notificationOrgin.Type = "nvarchar(6)"
notificationOrgin.DigestGrouping = True
flightNotifications.NotificationFields.Add(notificationOrgin)
