示例

This example shows a populated Action element for a ScheduledRule. The Transact-SQL statements use a notification function to create notifications, and also insert subscription data into a chronicle table.

<Action>
-- Insert notifications into scheduled notification class view
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;
-- Update 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>
