Hi
After upgrading Oracle from 11.2 to 12.1 (which required updating
cx_Oracle to 5.3 for some reason), {{manage.py inspectdb}} returns errors
{{{
# Unable to inspect table 'test_table'
# The error was: unorderable types: NoneType() > int()
}}}
My original install was 1.9, but upgrading to Django 1.10 gave the same
error. Oddly, the error in 1.9 came with a complete stack trace, while the
one in 1.10 only have the above error. Here's the stack from 1.9

The default database only contains tables that django itself has made and
that were not touched by any user directly.
