I just bombed my database midterm today. But I definitely would not say it’s my fault. I COULD have gotten 8 on 10 for the multiple choice part but I did not realize that there is something called standard SQL incoherence. In other words, SQL is an evil language that tries to be standardized but fails pathetically to do so. For instance, EXCEPT and MINUS are supposed to be equal in different implementations. If you only learned one and not the other, you are fucked up the ass by those zombies in Zelda.
