Beispiel
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 <= 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>
