Thank you for your idea, Mark,
To explain more about the problem Before we have 2 databases which they both have same sturcture andsame 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 <table>_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 <table>_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.
Regards,
Mark.

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. HTH. Arup Nanda
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.
Ukrit K,
