I have a website. Visitors can register. Every user can send messages to another user. There are in/out boxes. I want when a user deletes a message from his box the other user to still have it.

My question is can this be made with only one field in the table?

Why?
I couldn’t think of good solution. Curiousity, friends!

    Yes.

    With one column, the flow would require a nullable column.

    • NULL means both have them.
    • If one deletes – UPDATE that user’s id in the column.
    • When the other user deletes it – you can DELETE the record.

    I strongly advice using a more robust architecture though, less columns doesn’t equal better.

    @cwallenpoole Has a good example, try it out.
