Describes a scheduled rule that uses condition actions to generate notifications.

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

Syntax

'Declaration
Public NotInheritable Class SubscriptionConditionScheduledRule
    Inherits NamedSmoObject

public sealed class SubscriptionConditionScheduledRule : NamedSmoObject

public ref class SubscriptionConditionScheduledRule sealed : public NamedSmoObject

public final class SubscriptionConditionScheduledRule extends NamedSmoObject

public final class SubscriptionConditionScheduledRule extends NamedSmoObject

Remarks

A SubscriptionConditionScheduledRule object is a subscription rule that runs during each generator quantum that has subscriptions to process, and runs against scheduled subscriptions that use conditions.

A SubscriptionClass object can have zero or more SubscriptionConditionScheduledRule objects. A SubscriptionClass object can also use the following types of subscription rules: SubscriptionConditionEventRule, SubscriptionEventRule, and SubscriptionScheduledRule.

For more information about subscription rules, see Defining Subscription Rules.

Add individual SubscriptionConditionScheduledRule objects to a SubscriptionClass object using the SubscriptionConditionScheduledRules property, which returns a SubscriptionConditionScheduledRuleCollection object.

Example

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

// Add a rule to generate condition-based, scheduled notifications
SubscriptionConditionScheduledRule flightConditionScheduledRule = 
    new SubscriptionConditionScheduledRule(
    flightSubscriptions, "FlightConditionScheduledRule");
flightConditionScheduledRule.ActionTimeout = 
    new TimeSpan(0, 2, 0);
flightConditionScheduledRule.SqlLoginName = "MyLowPrivLogin";
flightConditionScheduledRule.SqlUserName = "MyLowPrivUser";
flightConditionScheduledRule.InputTypeName = "FlightEventChronicle";
flightConditionScheduledRule.InputTypeSchema = "MyAppSchema";
flightConditionScheduledRule.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.FlightConditionScheduledRule;";
flightSubscriptions.SubscriptionConditionScheduledRules.Add(
    flightConditionScheduledRule);

' Add a rule to generate condition-based, scheduled notifications
Dim flightConditionScheduledRule As _
    SubscriptionConditionScheduledRule = _
    New SubscriptionConditionScheduledRule( _
    flightSubscriptions, "FlightConditionScheduledRule")
flightConditionScheduledRule.ActionTimeout = _
    New TimeSpan(0, 2, 0)
flightConditionScheduledRule.SqlLoginName = "MyLowPrivLogin"
flightConditionScheduledRule.SqlUserName = "MyLowPrivUser"
flightConditionScheduledRule.InputTypeName = _
    "FlightEventChronicle"
flightConditionScheduledRule.InputTypeSchema = "MyAppSchema"
flightConditionScheduledRule.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.FlightConditionScheduledRule;"
flightSubscriptions.SubscriptionConditionScheduledRules.Add( _
    flightConditionScheduledRule)
