Notas

If you define multiple statements, a statement with an Exclude action takes precedence over a statement with an Include action. If no Include statement is defined, inputs are included by default. Otherwise, inputs are excluded by default.

Ejemplo

The following example shows a filter with one filter statement. The filter includes rows from the Production.Location table where the Name value is Subassembly. This filter is then used in a LinkLeafCondition, which joins the event and location data, including only those events that meet the filter conditions.

// Subscribe to products in Subassembly location. This
// requires select permissions on all tables in the sample.

//Specify server and database.
Server server = new Server("MyServer");
Database db = server.Databases[nsApplication.DatabaseName];

// Specify tables and views used by the condition.
Table locationTable = db.Tables["Location", "Production"];
Table inventoryTable = db.Tables["ProductInventory", "Production"];
View eventView = db.Views["InventoryTrackerEvents",
    "NS_InventoryTrackerApplication"];

// Filter defining "Subassembly" locations.
FilterRule toolCrib = new FilterRule(
    new TableInputType(db.Tables["Location", "Production"]),
    new SimpleLeafCondition(new FieldValue("Name"),
        SimpleOperator.Equals, "Subassembly"));

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

// Define a condition using the filter.
s.Condition = new LinkLeafCondition(
    LinkLeafOperator.Any,
    toolCrib,
    new JoinClause(eventView.Columns["ProductId"],
        inventoryTable.Columns["ProductId"]),
    new JoinClause(inventoryTable.Columns["LocationId"],
        locationTable.Columns["LocationId"]));

// Add subscription.
s.Add();
