Public Property RuleName As String

public string RuleName { get; set; }

public:
property String^ RuleName {
    String^ get ();
    void set (String^ value);

public function set RuleName (value : String)

Property Value

A string containing the name of a subscription rule, either event-driven or scheduled, that uses condition actions.

Remarks

In SQL Server 2000 Notification Services, subscribers create subscriptions by defining parameter values for pre-defined queries. In SQL Server 2005 Notification Services, your subscription classes can have condition actions, which allow subscribers to define more complex conditions.

If your application uses condition actions, your subscription management application must provide a Condition property and must also specify the RuleName for the condition.

The RuleName property specifies which subscription rule the subscription is for. This property is required for condition-based subscriptions so that the condition evaluator runs the conditions against the correct view.

For more information about conditions, see Defining Condition Actions.

Example

The following example shows how to define a condition for a subscription:

' Create the NSInstance object.
Dim testInstance As New NSInstance("InventoryTrackerInstance")
 
' Create the NSApplication object.
Dim testApplication As _
    New NSApplication(testInstance, "InventoryTracker")
 
' Create Subscription object.
Dim s As New Subscription(testApplication, _
    "InventoryTrackerSubscriptions")
 
' Define subscription properties
s.SubscriberId = "TestUser1"
s.Enabled = True
s.RuleName = "InventoryTrackerRule"
s("DeviceName") = "Work e-mail"
s("SubscriberLocale") = "en-US"
 
' Define OrCondition
s.Condition = New AndCondition( _
    New SimpleLeafCondition( _
        New FieldValue("ProductName"), _
        SimpleOperator.Equals, _
        "Road-250 Black, 48"), _
    New SimpleLeafCondition( _
        New FieldValue("LocationName"), _
        SimpleOperator.Equals, _
        "Final Assembly"), _
    New SimpleLeafCondition( _
        New FieldValue("Quantity"), _
        SimpleOperator.LessThanOrEqualTo, _
        35))
 
' Add subscription
s.Add()

// Create the NSInstance object.
NSInstance testInstance = 
    new NSInstance("InventoryTrackerInstance");

// Create the NSApplication object.
NSApplication testApplication =
    new NSApplication(testInstance, "InventoryTracker");

// Create Subscription object.
Subscription s = new Subscription(testApplication, 
    "InventoryTrackerSubscriptions");

// Define subscription properties
s.SubscriberId = "TestUser1";
s.Enabled = true;
s.RuleName = "InventoryTrackerRule";
s["DeviceName"] = "Work e-mail";
s["SubscriberLocale"] = "en-US";

// Define OrCondition
s.Condition = new AndCondition(
    new SimpleLeafCondition(new FieldValue("ProductName"),
                    SimpleOperator.Equals,
                    "Road-250 Black, 48"),
    new SimpleLeafCondition(new FieldValue("LocationName"),
                    SimpleOperator.Equals,
                    "Final Assembly"),
    new SimpleLeafCondition(new FieldValue("Quantity"),
                    SimpleOperator.LessThanOrEqualTo,
                    35)
);

// Add subscription
s.Add();
