Best way to make a table of non-unique rows, unique?

Gang,

I have some tables from a vendor using OLD, OLD, OLD, non-relational architecture which allows duplicate rows. I need to find a way to make the rows in these tables capable of having uniqueness for a unique key, even it the rows are "copied" and kept updated to like-type tables.

Since I can't touch the original tables because they are from a vendors app., I was thinking of copying the rows in the original tables to new tables with an added column wherein I could put something like a datatimestamp to make the row unique. I'd like to use something at the database level like a trigger or stored procedure but, if necessary, I'll write an old fashion program to do the work.

The reason for all this is that I'm using DataPropagator to map and keep in sync tables in a data warehouse in a separate LPAR and DataPropagator has to build a unique key over the target tables based on whatever makes rows unique in the source tables. Well, if the source tables have duplicates, I have to find a way around that or DataPropagator won't work for the last 11 tables I have to map/keep in sync.

Thanks in advance,

David Odom
