Osservazioni

Each event rule must be associated with a single event class. Notification Services fires the event rule only after processing event batches from the specified event class.

Esempio

The following examples show how to define an event rule and then add it to a subscription class:

// Add a rule to generate basic event-triggered notifications
SubscriptionEventRule flightEventRule = 
    new SubscriptionEventRule(flightSubscriptions, 
    "FlightSubscriptionsEventRule");
flightEventRule.Action = "INSERT INTO FlightNotifications " + 
    "(SubscriberId, DeviceName, SubscriberLocale, " + 
    "LeavingFrom, GoingTo, Price) " + 
    "SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, " + 
    "E.LeavingFrom, E.GoingTo, E.Price " + 
    "FROM FlightEvents E, FlightSubscriptions S " + 
    "WHERE     E.LeavingFrom     = S.LeavingFrom " + 
    "AND    E.GoingTo    = S.GoingTo " + 
    "AND    E.Price    < S.Price";
flightEventRule.ActionTimeout = new TimeSpan(0, 1, 0);
flightEventRule.EventClassName = "FlightEvents";
flightSubscriptions.SubscriptionEventRules.Add(flightEventRule);

' Add a rule to generate basic event-triggered notifications
Dim flightEventRule As SubscriptionEventRule = _
    New SubscriptionEventRule(flightSubscriptions, _
        "FlightSubscriptionsEventRule")
flightEventRule.Action = _
    "INSERT INTO FlightNotifications " + _
    "(SubscriberId, DeviceName, SubscriberLocale, " + _
    "LeavingFrom, GoingTo, Price) " + _
    "SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, " + _
    "E.LeavingFrom, E.GoingTo, E.Price " + _
    "FROM FlightEvents E, FlightSubscriptions S " + _
    "WHERE E.LeavingFrom = S.LeavingFrom " + _
    "AND E.GoingTo = S.GoingTo " + _
    "AND E.Price < S.Price"
flightEventRule.ActionTimeout = New TimeSpan(0, 1, 0)
flightEventRule.EventClassName = "FlightEvents"
flightSubscriptions.SubscriptionEventRules.Add(flightEventRule)
