How to resolve foreign key change during import?

[minjie]

Hello,
I have to implement the following requirement: from an application, a
user can export some info retrieved from DB2, and later import the
info into another DB2 on another machine. The user is not supposed to
be knowledgeable about DB2, so he is not expected to manipulate the
data between the export and import. I have thought of the following
method: use the DB2 export and import utilities, and use DEL as file
format. The export will result in a file with data from a parent
table, and several other files with data from bunch of dependent
tables that have references to the parent table via foreign keys. I'll
import the parent table with 'modified by identityignore' option, in
which case the primary key value will be different from the original
one, which means all the foreign key values in other files have to be
modified to the new value during import. Is there a way to do so with
DB2?
Thanks.
