| If you add or delete an IndexSqlSchema element, updating the application deletes and re-creates the event class to which it corresponds. This includes dropping and re-creating the SQL Server tables and indexes used by this event class. Any data existing in the original SQL Server tables is permanently deleted. |
Ejemplo
The following example shows how to create an index named StockIndex on the StockSymbol field of the StockEvents table in the application database.
<IndexSqlSchema>
<SqlStatement>
CREATE INDEX StockIndex
ON StockEvents (StockSymbol)
</SqlStatement>
</IndexSqlSchema>
