One-to-one relationship on delete
Hello, I have a parent table called asset and a child table called user. user table has a 1-1 relationship with asset as 1 user can only use 1 asset. And 1 asset can only belong to 1 user.
The thing is, at the point of asset creation, it is possible that there is no user yet until after some times, which means user could potentially be empty for a long time.
Now, I want to set up a relationship such that if I delete an asset, it will delete the user too. I have set up the relationship as Cascade. But, I noticed that when I delete the user, it also deletes the asset, which I don't want.
How do I set it such that:
- If I delete
asset, it deletes its associateduser - If I delete
user, nothing happens toasset
TL;DR
The developer wants to set up a one-to-one relationship between the `asset` and `user` tables. They want to ensure that deleting an `asset` will also delete the associated `user`, but deleting a `user` will not affect the `asset`.
To achieve this, the developer should set up a one-to-one relationship with the DELETE CASCADE option from the `asset` table to the `user` table. This way, deleting an `asset` will automatically delete its associated `user`. However, the relationship from the `user` table to the `asset` table should not have any delete actions defined, so deleting
