Here is what is going on at House-O-Pets: you have just set up a data warehouse system that contains copies of all your customer transactions in several new partitioned tables. You want to update all the warehouse customer records with a timestamp to record when you added the records into the data warehouse. You also want to run a parallel query on the customer object table that sorts customers by their purchase amounts.
Starting with the code in your downloaded file, modify the file to complete these tasks:
- Add a parallel update of the
CUSTOMER
table. Update the WAREHOUSE_DATE column with the current date and time.
- Add a
MAP METHOD
function called HIBUY
to the CUSTOMER_SALES
that returns the TOTAL_SALE_AMOUNT column.
- Add a parallel query on the
CUSTOMER_SALES
object table that lists the customers name and purchase amount, sorted by the MAP METHOD
you created.
