[Ross Elliott]

Thanks for the offer. I'd be more than willing to re-compile from source :-)

Ross,

Whew!  Thats a quite a table.

No, there is currently no way to request a particular column be used as
the FID but it wouldn't be hard to add some sort of a hack.  The
decision rule currently is implemented circa line 204 of ogrocitablelayer.cpp.
This could easiliy be altered to check for an environment variable or some
other configuration means to indicate a field name.

I would like to spend some time working on the Oracle driver but currently my
partition with Oracle is inaccessable (damn Fedora Core 2 bootloader
screwer-upper).

So, if you are in a position to recompile your binaries from source I could make
a small adjustment to the code for you.

Best regards,
