Valeur de propriété
The SubscriptionConditionEventRuleCollection for the subscription class.
Notes
The SubscriptionConditionEventRuleCollection represents the set of condition-based event rules for the subscription class. Use this collection to get, add, and remove SubscriptionConditionEventRule objects for the subscription class.
If you add or delete a rule, updating the application re-creates the subscription class to which it corresponds. Notification Services renames the existing subscription tables by appending Old to the table name and then creates new tables. Existing subscription table indexes are left unchanged.
If you want to transfer data between the old and new subscription tables, it must be done manually. For more information, see Mise à jour d'une application.
Exemple
The following examples show how to define and add a condition-based, event-driven subscription rule to a subscription class:
// Add a rule to generate condition-based, event notifications
SubscriptionConditionEventRule flightConditionEventRule =
new SubscriptionConditionEventRule(
flightSubscriptions, "FlightConditionEventRule");
flightConditionEventRule.EventClassName = "FlightEvents";
flightConditionEventRule.ActionTimeout = new TimeSpan(0, 2, 0);
flightConditionEventRule.SqlLoginName = "MyLowPrivLogin";
flightConditionEventRule.SqlUserName = "MyLowPrivUser";
flightConditionEventRule.InputTypeName = "FlightEvents";
flightConditionEventRule.InputTypeSchema = "MyAppSchema";
flightConditionEventRule.SqlExpression =
"INSERT INTO MyAppSchema.FlightNotifications (SubscriberId, " +
"DeviceName, SubscriberLocale, LeavingFrom, GoingTo, Price) " +
"SELECT [Subscription.SubscriberId], [Subscription.DeviceName], " +
"[Subscription.SubscriberLocale], " +
"[Input.LeavingFrom], [Input.GoingTo], [Input.Price] " +
"FROM MyAppSchema.FlightConditionEventRule;";
flightSubscriptions.SubscriptionConditionEventRules.Add(
flightConditionEventRule);
' Add a rule to generate condition-based, event notifications
Dim flightConditionEventRule As _
SubscriptionConditionEventRule = _
New SubscriptionConditionEventRule( _
flightSubscriptions, "FlightConditionEventRule")
flightConditionEventRule.EventClassName = "FlightEvents"
flightConditionEventRule.ActionTimeout = New TimeSpan(0, 2, 0)
flightConditionEventRule.SqlLoginName = "MyLowPrivLogin"
flightConditionEventRule.SqlUserName = "MyLowPrivUser"
flightConditionEventRule.InputTypeName = "FlightEvents"
flightConditionEventRule.InputTypeSchema = "MyAppSchema"
flightConditionEventRule.SqlExpression = _
"INSERT INTO MyAppSchema.FlightNotifications " + _
"(SubscriberId, DeviceName, SubscriberLocale, LeavingFrom, " + _
"GoingTo, Price) SELECT [Subscription.SubscriberId], " + _
"[Subscription.DeviceName], [Subscription.SubscriberLocale], " + _
"[Input.LeavingFrom], [Input.GoingTo], [Input.Price] " + _
"FROM MyAppSchema.FlightConditionEventRule;"
flightSubscriptions.SubscriptionConditionEventRules.Add( _
flightConditionEventRule)
