Параметры

subscriptionClass
The parent SubscriptionClass for the SubscriptionConditionEventRule. The rule is evaluated for condition-based subscriptions in the specified subscription class.

name
A String, between 1 and 255 characters in length, that specifies the event rule name.

You cannot change the name. To rename a rule, you must remove it and then add a rule that has the new name.

Замечания

The name string must be unique within the application.

This constructor sets a default ActionTimeout value of 30 minutes.

Пример

The following example shows how to define a condition-based, event-driven subscription rule and add it 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)
