Example

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)
