Answer 1

And just so you can see....
We can also get the totals and even break down the cursors to show individual orders within each of the companys...
SQL> select * from test;
CO ORDER_NUMBER    ITEM_ID   QUANTITY ITEM_DESC
A          1001          1         10 apple
B          1002          2         50 banana
B          1002          1         30 orange
B          1003          2         40 pear
B          1003          1         70 grapefruit
