SqlStatement Element for SubscriptionClass/IndexSqlSchema (ADF)

Contains a Transact-SQL statement that creates a SQL Server index for the subscription table.

    <SubscriptionClass>
        ...
        <IndexSqlSchema>
            <SqlStatement>

Remarks

If you add, delete, or update the indexing SqlStatement element, updating the application deletes and re-creates the subscription class to which it corresponds. This includes dropping and re-creating the SQL Server tables and indexes used by this subscription class. Any data existing in the original SQL Server tables is permanently deleted.

Example

The following example shows a SqlStatement element that creates an index on the StockSubscriptions table.

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