SubscriptionScheduledRule Class

Represents a scheduled rule that contains actions, not condition actions.

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

public sealed class SubscriptionScheduledRule : NamedSmoObject
public final class SubscriptionScheduledRule extends NamedSmoObject
public final class SubscriptionScheduledRule extends NamedSmoObject

The SubscriptionScheduledRule class represents a rule that uses simple parameter-based Transact-SQL queries to generate notifications for scheduled subscriptions.

Each SubscriptionScheduledRule object must specify an action, which is a Transact-SQL query that does the work of the rule. A subscription class can have multiple SubscriptionScheduledRule objects, and can also have SubscriptionConditionScheduledRule, SubscriptionEventRule, and SubscriptionConditionEventRule objects.

SubscriptionScheduledRule objects are associated with a subscription class through the SubscriptionScheduledRules property.

The following examples show how to define a scheduled rule and add it to a subscription class:

// Add a rule to generate basic scheduled notifications
SubscriptionScheduledRule flightScheduledRule = 
    new SubscriptionScheduledRule(
    flightSubscriptions, "FlightScheduledRule");
flightScheduledRule.Action = "INSERT INTO FlightNotifications " + 
    "(SubscriberId, DeviceName, SubscriberLocale, " +
    " LeavingFrom, GoingTo, Price) " + 
    " SELECT S.SubscriberId, S.DeviceName, S.SubscriberLocale, " +
    " EC.LeavingFrom, EC.GoingTo, EC.Price " + 
    " FROM FlightEventChronicle EC, FlightSubscriptions S " +
    " WHERE EC.LeavingFrom = S.LeavingFrom " + 
    " AND EC.GoingTo = S.GoingTo " +
    " AND EC.Price < S.Price";
flightScheduledRule.ActionTimeout = new TimeSpan(0, 0, 30);

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
