Question

Answer 1

You don't specify whether this feature is needed as part of production code, or if you're trying to join the two tables to perform some one-time analysis. If it's the latter, you can use Microsoft Access to create a local mdb file that contains linked tables to the two databases, then write a local Access query that refers to those two tables. You could then use that mdb as a data source for various reporting tools.

The queries might not use indexes as efficiently as a native Oracle db link, but it would be better than nothing.

edit: Nevermind - I see that this was already suggested above.
