Row to Column transformation on an update form

Question

I'm trying to create an updateable HTML-DB application that does the following. Any idea, the best way to do this?
Converts table rows into HTML-DB columns.
Create table INV_ORDERS
(Month date,
Beg_Inv number,
Planned_orders number
select * from INV_ORDERS;
Month Beg_Inv Planned_Orders
NOV-2005 10 20
DEC-2005 30 40
JAN-2006 50 60
How can I pivot it to be:
NOV-2005 DEC-2006 JAN-2006
Beg_Inv 10 30 50
Planned_Orders 20 40 60
The pivot numbers need to be updatable (via HTML-DB).
Thank you.

Answer 1

As it stands, your problem definition is quite "hard". Each column in the HTML DB tabular form belongs to a different physical row. You could try creating the tabular form off of a view that does the pivot and writing a INSTEAD OF trigger on that view, but it is not going to be easy.
But why?
What problem are you trying to solve, maybe we can suggest a different approach?
