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 customer’s name and purchase amount, sorted by the MAP METHOD you created.
