Thank you for your idea, Mark,
To explain more about the problem
Before we have 2 databases which they both have same sturcture and
same database objects names. We have 2 set of D2K forms and reports to
access to each database.
After merging, we looking for move data from database B to
database A but still be able to access by using the different of forms and
reports. However the tables which be move from database B to datbase A,
will be rename to
_B.
The developer just throw me a fire ball that what-if they don't
modify the forms and reposts, is it possible to have one set of the forms
access the _B

Also, depending on your requirements (which I don't fully understand)
another approach may involve using views:
The CUSTOMERS view could point to either CUSTOMERS_A, CUSTOMERS_B or even
the merge of both tables (select * from customers_a union all select *
from
customers_b) if required. Of course you may introduce primary and foreign
key problems, but like I said - I don't fully understand your requirement
so I'm just throwing ideas up in the air.

Please respond to
ORACLE-L
You can drop or rename CUSTOMERS to, say, CUSTOMERS_A, and then create
synonym CUSTOMERS pointing to CUSTOMERS_B. Or rename CUSTOMERS_B to
CUSTOMERS.

Subject: Transparent database objects after merging
Hello Gurus,
I'm working merging 2 databases which have sane structure of
database objects into one database. However, after merging, the business
policies and regulations force us to have 2 set of database objects; for
example :
Database A has CUSTOMERS table.
Database B has CUSTOMERS table.
After merging database A will have CUSTOMERS and CUSTOMERS_B (data from
database B). I just wonder that is there any way that we don't need to
change our script in forms and reports to point into a new table name but
still can access to the data in the new table ( CUSTOMERS_B) not
CUSTOMERS.
Thank you for any comment and suggestion.
