Import a database

Question

Hi,
I want to import a database A(Source) to another database B(Target).
Scenario is as follows
Database A
HIN          Name          Father          Date
1234501     Rahul          Suresh          01/01/2011
Database B
HIN          Name          Father          Date
1234502     Rahul          Suresh          05/05/2011
HIN will be same, except for last two digits, for particular user
Its a possibility that the particular user could exist in Database B.So,My requirement is to first check the HIN for any user,if all digits are same, except last two digits,then the Name & Father will be checked and if both are also same then the data from Database A to be added (not overwrite) to Database B.
The result should be like this:
Database B
HIN          Name          Father          Date
1234502     Rahul          Suresh          05/05/2011
1234502     Rahul          Suresh          01/01/2011
How can it be possible,Please help me out.
Thanx

You can do it with SQL and PL/SQL
If you want to do it with Data Pump, check REMAP_DATA parameter (it's available at 11g). Using this parameter you can remap the data at it is being inserted into the database. Check the following links:
