    Oracle Auto increment trigger HOWTO

    Oracle SQL Developer is full of nice feature, damned by a overwhelming options pane, like the one I will describe to you right now.

    Even if  Oracle databases (<12) does not support auto increment, you can easily ask to your sql data modeler to generate for you a sequence and a trigger in a automatic way.

    I am smarter syndrome

    Sometimes in University I found bold young guy saying something like:

    I will reimplement this in machine language because is faster

    I will reimplement this xyz C function by my own

    My program crash, I think there is a bug in HP UNIX socket implementation

    I will ge rid of this Java Garbage Collector because it is too slow. I will reimplement all the code in my C++ routine.

     

    Belive me: your code is doomed. A full list of guys have already done your same code, found a million bugs and corrected it in the tool you want to replace because they are shitty slow, to your eyes.

    I feel your pain because I made your same mistake. Keep reading.
