Hinweise

If you delete a Chronicle element, updating the application re-creates the subscription class to which it corresponds. SQL Server 2005 Notification Services renames the existing tables for the subscription class by appending "Old" to the table names. Existing subscription table indexes are left unchanged. If you want to transfer data between the old and new subscription tables, it must be done manually. For more information, see Aktualisieren einer Anwendung.

Beispiel

The following example shows a Chronicle element that deletes any existing table named StockSubscriptionChron and then creates the StockSubscriptionChron chronicle table.

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