If you add or delete fields, updating the application deletes and re-creates the event class. This includes dropping and re-creating the SQL Server tables and indexes used by this event class. Any data existing in the original event class tables is permanently deleted.

<Field>
    <FieldName>StockSymbol</FieldName>
