[Q] Handle Informix + Oracle DB from same C++-program?

Hi,

I am investigating the possibility to have *one* C(++)-program that can insert, update, select... in both an Informix and Oracle database.

I wonder if this is possible at all as both vendors make use of the sqlca structure. The program would have to pass through Pro*C++ as well as ESQLC (this does not sound feasible, does it?). I do not *have* to be able to join between Informix and Oracle tables, but maybe in a year or so I want that, too.

Would ODBC help here? Remember, I need a C(++)-program. Which products can be of use (except Oracle-Gateways-to-Informix which is far too expensive)?
TIA
