A long time ago back in Micosoft SQL server 6 there was one issue that really bugged the living crap out of me. You could not rename a column name. Now why this was I have no idea except there was some lazy programmer who decided this was too much work. Then the heridad day came when version 7 came a long and that was gone. All RDMS systems were now basically functionally equal. I have now found the one item that make me sad and angry all in one thought.
