Замечания

When you use a condition action, you must specify which view or table contains the event data. This view or table is in a schema.

• If the input is the view named after the event class, the schema is the application schema. The application schema can be specified when defining the application database, or it can be the default value of dbo. For more information, see Определение базы данных приложений.
• If the input is an event chronicle, the schema is defined in the CREATE TABLE statement that creates the event chronicle. This is usually the same as the application schema. For more information, see Определение хроники для класса событий.

For more information about condition actions, see Определение условных действий.

Пример

The following example shows how to define a condition action. The query in the Transact-SQL expression selects data from the MyAppSchema.WeatherEventRule 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.WeatherEventRule;
    </SqlExpression>
</ConditionAction>
