주의

An application is not required to have event classes. The Transact-SQL queries that generate notifications can obtain data from other sources.

중요:
If you delete the EventClasses group of elements, updating the application deletes the event classes, including all related SQL Server tables and indexes. Any data existing in the original event class tables is permanently deleted.

예

The following example shows an EventClasses element that has placeholders for two event classes. For an example of an event class, see EventClass Element (ADF).

<EventClasses>
    <EventClass>
    <!-- Define first event class here -->
    </EventClass>
    <EventClass>
    <!-- Define second event class here -->
    </EventClass>
</EventClasses>
