Databases support versioning? What planet do you live on?

Maybe you're talking about the Subversion database?

    What planet do you live on?

    One where people have a modicum of imagination?

    select code from modules where function eq 'sort' and type eq 'in-place' and version >= 3.7;

    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    Lingua non convalesco, consenesco et abolesco.
    Rule 1 has a caveat! -- Who broke the cabal?

      That's not versioning, it's a query.

      I thought database versioning was one of the "classic hard problems" with databases. Have you found a magical solution to this problem that the rest of us have missed? I look forward to your "modicum of imagination" on this topic.

        I thought database versioning...

        Re-read the context. Modules have version numbers. Sometimes you need to retain access to an older version of a module for one application, whilst moving to using the latest version for new applications. Retaining access to both (or more) versions of the module within the same Perl installation is a problem not currently easily addressable.

        The simple expedient of adding a "Version" field to the "Modules" table would allow each application to request any of: the latest version; a specified version; any version before (or after) a given version; etc.

        In this context, I chose the word "versioning" to describe that possibility.

        Whatever other interpretation you have chosen to read into my use of that word in this context--is wrong.
