What will be an ideal response?
Consider a relation schema MyAccount (StockSymbol, Quantity, Price), which records the user's stock holdings: the name of the stock, quantity, and current price. StockSymbol is a key. The user wants a small window on her desktop to show the following view:
CREATE VIEW MyTotals(StockSymbol, Total) AS SELECT M.StockSymbol, M.Quantity * M.Price FROM MyAccount MThe stock broker allows the user to compute the value of the view only once a day, so periodic recomputation of the view is not an option. However, the broker allows triggers that re whenever an update to the rows of MyAccount occurs. Write a row-level trigger that can provide the user with an up-to-date view of the above kind.
