Beispiel

This example shows a populated Action element. The Transact-SQL statements insert a row into the chronicle table if the stock information doesn't exist, and update the stock information if a row already exists.

<Action>
-- Insert New Stock Symbols with Prices
INSERT dbo.StockEventsChron (StockSymbol, StockPrice)
SELECT e.StockSymbol, e.StockPrice
    FROM dbo.StockEvents AS e
    WHERE e.StockSymbol
        NOT IN (SELECT StockSymbol FROM dbo.StockEventsChron);
-- Update Existing Stock Symbols with New Prices
UPDATE dbo.StockEventsChron
    SET StockPrice = e.StockPrice
    FROM dbo.StockEvents AS e 
    JOIN dbo.StockEventsChron AS c
        ON e.StockSymbol = c.StockSymbol
        WHERE e.StockPrice &gt; c.StockPrice;
</Action>

This example shows how to call a stored procedure that maintains the event chronicle.

<Action>
EXEC MyStoredProcdure;
</Action>
