Hi
After upgrading Oracle from 11.2 to 12.1, {{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.
