        <Action>
        -- Generate Notifications
        INSERT INTO ScheduledNotifications
        ( SubscriberId, DeviceName, SubscriberLocale,
          StockSymbol, StockPrice )
        SELECT S.SubscriberId, S.DeviceName, 
            S.SubscriberLocale, C.StockSymbol, C.StockPrice
        FROM StockSubscriptions S JOIN StockEventChron C
        ON S.StockSymbol = C.StockSymbol 
        WHERE S.StockTriggerPrice &lt;= C.StockHighPrice 
        GROUP BY S.StockSymbol, C.StockHighPrice
        -- Maintain the subscription chronicle
        INSERT StockSubscriptionChron
        (SubscriberId, StockSymbol, StockPrice)
        SELECT S.SubscriberId, S.StockSymbol, C.StockHighPrice
        FROM StockSubscriptions S JOIN StockEventChron C
        ON S.StockSymbol = C.StockSymbol
        </Action>

    </ScheduledRule>
    <ScheduledRule>
        <RuleName>StockSubArchiveRule</RuleName>
        <Action>
        -- Maintain an archive table
        INSERT StockSubscriptionArchive
        (SubscriberId, StockSymbol, StockPrice, ArchiveDate)
        SELECT S.SubscriberId, S.StockSymbol, S.StockPrice, GETDATE()
        FROM StockSubscriptionsChron S
