You want to unload data from the ORDERS, ORDER_ITEMS, and PRODUCTS database tables to four os flat files by using the External Table Population methods. To achieve this objective, you execute the following command:
Create TABLE orders_ext
(order_id, order_date, product_id, product_name,quantity)
ORGANIZATION EXTERNAL
(
TYPE ORACLE_DATAPUMP
DEFAULT DIRECTORY ext_dir
LOCATION (‘orders1.dmp’,’orders2.dmp’,’orders3.dmp’,’orders4.dmp’)
)
PARALLEL
AS
SELECT
o.order_id,o.order_date,p.product_id,p.product_name,i.quanity
FROM orders o,products p,order_items i
WHERE o.order_id = i.order_id and i.product_id = p.product_id;
After successful execution of the command, you find that only two files have been created and not four. Which option do you need to change to achieve your objective?
