HOWTO Import Only Table's Data

I want to import data from one DB to another,
but only data without affecting the table structure and names.
In the import dialog box has only two options,
import tables and data
import tables only.
I want the third one ;)
import data only.
Is there any automatic way or do I have to make a VB sub?

What I'm doing now is to importing tables and data
to the second DB, but as u know this results in having every table
twice like Students Students1 Classes Classes1 and so on.
Then I'm removing one by one all the old tables and then renaming every the
Table1 to Table.
As you can imagine this is not a practical solution and it can be implemented only to small DBs, with a small number of tables.
In my case we are talking about a huge DB with over 20 tables,
and the above process (importing data) has to be done at least once per month.

Let me inform you that copying data and only data from one base to another is the only method suits in my case so please avoid suggesting alternative solutions.

Thanks in advance
