Maybe something like this would work for you:
http://trac.osgeo.org/mapserver/ticket/2129
I did this a few years ago for a client but it was between Oracle
developers and never got put in the trunk code. I don't work with an
Oracle instance at the moment but there is a patch and you might be able
to adapt it to your needs.
