In-database archiving is a neat, new 12c-functionality that lets you logically “delete” rows by changing a flag in a column: A “soft-delete”. How does this functionality work in relation to foreign keys?

In-database archiving + ANSI re-architecture = bug
I had a task to clean up some data and I decided to use in-database archiving, a new feature in 12c. As I was working I noticed some unexpected resultsets along the way. I was quite puzzled for a little time, so I set up a test-case and realized that I’ve struck on a bug. The bug seems related to the ANSI re-architecture-features of the optimizer.
- nice theory...
