I would update the IDs using SQL before dumping if possible. If necessary clone the tables, adjust the IDs and then dump. SQL has better tools than most languages/scripts to adjust values in columns across multiple entities. Plus it should be easier to build some test queries in SQL to validate that your ID adjustments were valid.

Hi Folks:

I'm looking at directions or help in extracting data from production and alter employee id information while extracting.  But at the same time maintain referential integrity across tables. Is it possible to dump data to flat file and then run some script to change emp id data on all files.  I'm looking for a easy solution.

Thanks,
