Hi,

We have a table like this:

CUSTOMER_ID
PRODUCT_ID
FORMAT
STATUS
DATE_ADDED
DATE_MODIFIED

We also have a history table like this:

CUSTOMER_ID
PRODUCT_ID
FORMAT
STATUS
SOURCE
DATE_ADDED

We want to put a trigger on the first table such that when a record is
inserted or updated it will make the entry to the history table.
However, the problem is the 'SOURCE' column on the history table. It
is not present or needed in the first table.

Entries into the first table are done through a PL/SQL program. So,
what we want is that when the entry is made into the first table, it
fires the trigger to make the second entry. But, how can this be done
if the columns do not match? Is there a way to do this?
