Notes

ms145895.note(fr-fr,SQL.90).gifImportant :
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.

Exemple

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>
