9/29    MySQL question:  If I create a table where one column is an ENUM such
        as ENUM('a','b','c') can I later expand the enumerated values to say
        add 'd' to the possibilities, or do I have to rebuild the whole table?
        \_ Not really (although I think this makes MySQL silently rebuilt
           the table anyway):
             ALTER TABLE foo CHANGE bar bar ENUM ('a','b','c','d');
           -geordan
           \_ Slightly shorter:
              ALTER TABLE foo MODIFY bar ENUM ('a','b','c','d');
