Initializes a new instance of the FilterRule class with a table or view input and one or more property statements.

Namespace: Microsoft.SqlServer.NotificationServices.Rules
Assembly : Microsoft.SqlServer.NotificationServices.Rules (in microsoft.sqlserver.notificationservices.rules.dll)

Syntax

'Declaration
Public Sub New ( _
    inputType As InputType, _
    ParamArray propertyStatements As PropertyStatement() _
)

public PropertyRule (
    InputType inputType,
    params PropertyStatement[] propertyStatements
)

public:
PropertyRule (
    InputType^ inputType, 
    ... array<PropertyStatement^>^ propertyStatements
)

public PropertyRule (
    InputType inputType, 
    PropertyStatement[] propertyStatements
)

public function PropertyRule (
    inputType : InputType, 
    ... propertyStatements : PropertyStatement[]
)

Parameter

inputType
The InputType that represents the input table or view. This parameter sets the InputType property.

propertyStatements
Zero or more PropertyStatement objects used to evaluate the input. This parameter sets the PropertyStatements property.

Hinweise

If you define zero PropertyStatement objects using the propertyStatements parameter, you must define at least one PropertyStatement using the PropertyStatements property. If you define multiple statements, the result of evaluating this rule is the result of the first statement with a matching Condition criteria, or NULL if no criteria is met.

Beispiel

The following example shows how to define a property rule that defines three properties: Few, Some, and Alot. It uses this property rule to define a subscription to events where Quantity equals Few:

// Define a new property that defines "Few," "Some," and "Alot"
// of inventory. 
PropertyRule quantityCategory = new PropertyRule(
    new ViewInputType(eventView),
    new PropertyStatement(new SimpleLeafCondition(
        new FieldValue("Quantity"),
        SimpleOperator.LessThan, 100), "Few"),
    new PropertyStatement(new BetweenLeafCondition(
        new FieldValue("Quantity"), 100, 200), "Some"),
    new PropertyStatement(new SimpleLeafCondition(
            new FieldValue("Quantity"),
            SimpleOperator.GreaterThan, 200),
        "Alot"));

// Create subscription and define basic properties.
s = new Subscription(nsApplication, subscriptionClassName);
s.SubscriberId = "Scott";
s.Enabled = true;
s.RuleName = "InventoryTrackerRule";
s.SetFieldValue("DeviceName", "myDevice");
s.SetFieldValue("SubscriberLocale", "en-us");


// Use the new property to return only products with "few" remaining
// in inventory. Note that the category definition can be reused.
s.Condition = new SimpleLeafCondition(
    new RuleValue(quantityCategory),
    SimpleOperator.Equals,
    "Few");

// Add subscription.
s.Add();
