Osservazioni

A condition action allows for flexible rules created by subscribers. ConditionAction elements contain elements that describe the input source and the query used to generate notifications from input and subscription data.

For more information about condition actions, see Definizione di azioni condizionali.

Esempio

The following example shows how to define a condition action. The query in the Transact-SQL expression selects data from the MyAppSchema.FlightEventRule view, which contains data from the subscription class and from the MyAppSchema.WeatherEvents event view.

<ConditionAction>
    <SqlLogin>[MyLowPrivLogin]</SqlLogin>
    <SqlUser>[MyLowPrivUser]</SqlUser>
    <InputName>WeatherEvents</InputName>
    <InputSchema>MyAppSchema</InputSchema>
    <SqlExpression>
        INSERT INTO MyAppSchema.WeatherNotifications(SubscriberId, 
        DeviceName, SubscriberLocale, City, Forecast) 
        SELECT [Subscription.SubscriberId], [Subscription.DeviceName],
               [Subscription.SubscriberLocale], [Input.City], 
               [Input.Forecast])
        FROM MyAppSchema.FlightEventRule;
    </SqlExpression>
</ConditionAction>
