주의

Use the FunctionValue class to use custom database logic to determine an argument value. Your user-defined function must have a scalar return type.

You must specify the user-defined function and parameters in the FunctionValue constructor or using the Parameters and Name properties.

예

The following example shows the definition of a user-defined function, and then uses this function to evaluate events:

// Subscription based on the following function definition:

/*
create function SoundexMatch(@x nvarchar(max), @y nvarchar(max))
returns bit
as
begin
    if soundex(@x) = soundex(@y)
        return 1

    return 0
end
 * */

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

// Define a condition that uses the function to evaluate
// if the condition is true.
s.Condition = new BooleanLeafCondition(new FunctionValue(
    db.UserDefinedFunctions["SoundexMatch", "dbo"],
    new FieldValue("ProductName"),
    "Rood-250 Black, 48"));

// Add subscription.
s.Add();
