SqlStatement Element for SubscriptionClass/IndexSqlSchema (ADF)

備註

If you add or delete an IndexSqlSchema element, updating the application re-creates the subscription class to which it corresponds. SQL Server 2005 Notification Services renames existing subscription tables by appending Old to the name and then creates new subscription tables. Existing subscription table indexes remain unchanged.

If you want to copy data between the old and new subscription tables, you must do so after updating the application. For more information, see 更新應用程式.

範例

The following example shows how to create an index named StockSubIndex on the SubscriberId field of the StockSubscriptions table in the application database.

<IndexSqlSchema>
    <SqlStatement>
    CREATE INDEX StockSubIndex
    ON StockSubscriptions (SubscriberId)
    </SqlStatement>
</IndexSqlSchema>
