Замечания

If you add, delete, or update the indexing SqlStatement element, updating the application deletes and re-creates the subscription class to which it corresponds. This includes dropping and re-creating the SQL Server tables and indexes used by this subscription class. Any data existing in the original SQL Server tables is permanently deleted.

Пример

CREATE INDEX StockSubIndex
ON StockSubscriptions (SubscriberId);
</SqlStatement>
