Re: unique constraint violation on 8i import but not on 9i

Do the import with the ignore=y option then.

As Alex already said - PK is enabled AFTER table data is loaded.

After you load everything up you will end up without that violated PK and some related FK's.

Do the "select col1, col2 from that_nasty_table group by having count(*) > 1" and see what is causing duplicates. Maybe this will give some clue.
