Обсуждение: How to select a postgresql table inside Oracle
Hi, I have a need to select some data in a Oracle database from a Postgresql table. I know how to do this among Oracle instances, eg. Select * from table@another_instance.
Are there similar approach without replicate the database tables?
Thanks in advance.

Probably the most simple way is using a dblink http://archives.postgresql.org/pgsql-hackers/2003-06/msg00361.php other way, you can use a plperlu and DBI interface http://www.pgsql.cz/index.php/PL/Perlu_-_Untrusted_Perl_%28en%29 Regards Pavel Stehule > > > Thanks in advance.

Or perhaps I do not understand your question.
