Oracle / Postgres Interface

Hi All,

I would appreciate any input on this dilemma:

1. I have DataBase-A which is Oracle on Server A with FunctionA
(PLSQL)
2. I have DataBase-B which is Postgress on Server B with FunctionB
(PgSQL)
3. I need to call FunctionA from FunctionB

I don't mind rewriting PgSQL to some other language in Postgress if need
be.

Can I do this? If Yes, How?

Please reply as soon as possible.

Thanks,

Sameer

As far as I know, the on'y way to do this is to write a Postgres
function (function B) in C that links with the Oracle client libraries,
connects to Oracle, and calls your function A.

If performance isn't an issue it might be faster to get going using a PerlU
function in Postgres that uses DBD::Oracle to connect to Oracle.

It's the same thing but you don't have to learn two new C APIs. If you already
know how to use Pro*C and the postgres C API then there's probably no benefit.
