Re: Transfer Data to another tablespace with different name

you want to make a copy, but preserve foreign keys. And I assume, you also want to preserve the table-name?
Which one should be the one which serves the Foreign Keys?

You also cannot have the same object twice within the same schema.

There might be methods how to keep the same data in two tables within the same schema; I would start checking streams or Replication.

If you want to make a copy of the tablespace, check maybe this will bring some inspiration ;-)

but first, please make sure what your demand is.

best regards,
