> Did I forget to add `WHERE deleted_at IS NULL` again?

This seems like an unaddressed use case on the part of the RDBMS to me, a feature that shouldn’t be reinvented by ORMs or each individual project.

Instead, you should be able to just do DELETE SOFT FROM … in your queries and have the DB make the rows unavailable in all queries.

Or maybe even set it up, so that regular DELETE is treated like a soft delete, so that suddenly all of the ORMs and users wouldn’t be able to drop data on accident.

Maybe allow overwriting it with DELETE /*+DELETE_HARD*/ FROM … if you so choose, as well as do SELECT /*+WITH_SOFT_DELETED*/ … if you don’t want to introduce any historical incompatibility.

If such features don’t exist at the DB or a DB extension level, then we’ll be doomed to deal with ORMs reimplementing it which will be pretty bad if you ever need more than one tech stack connected to it, alongside the issues of all of your queries needing additional conditions.
