Notas

Event chronicles are optional; use the Chronicle element and its child elements only if you need to maintain event information outside of the event tables used by an event class. A common reason to use event chronicles is to store and maintain event data for scheduled subscriptions. For more information, see Definir crónicas para una clase de evento.

Importante:
If you delete a Chronicle element, updating the application deletes and re-creates the event class to which the chronicle corresponds. This includes dropping and re-creating the Microsoft SQL Server tables and indexes used by the event class.

Ejemplo

The following example shows a Chronicle node that deletes any existing table named StockEventChon and then creates the StockEventChron event chronicle table.

<Chronicle>
    <ChronicleName>StockEventChron</ChronicleName>
    <SqlSchema>
        <SqlStatement>
        IF EXISTS (SELECT * FROM INFORMATION_SCHEMA.TABLES
            WHERE TABLE_NAME = &apos;StockEventChron&apos;)
        DROP TABLE StockEventChron
        </SqlStatement>
        <SqlStatement>
        CREATE TABLE StockEventChron
        (
        StockSymbol char(10),
        StockHighPrice money
        PRIMARY KEY (StockSymbol)
        )
        </SqlStatement>
    </SqlSchema>
</Chronicle>
