Description

I'm getting the following error when using inspectdb with an Oracle database. The column in question is a hidden column that's automatically created by the database, and doesn't need a model. The command runs fine if I add something to skip these columns. Here's a related issue in SQLAlchemy: ​https://github.com/sqlalchemy/sqlalchemy/issues/1513

Traceback (most recent call last):

Keywords: oracle inspectdb added
Summary: KeyError when running manage.py inspectdb against an Oracle database. → inspectdb crashes on Oracle databases with functional indexes.
Triage Stage: Unreviewed → Accepted

I'm aware there are hidden/internal columns on Oracle, so it seems valid. Would you like to provide a patch?
