Notas
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.
