    Wow, that's kind of stupid that there's no before.
  • James · 10 months ago
    Why do you need a before? If its the first one, you use first, if its the second one, you use after first.

    Actually "HEAD FIRST SQL" (book by O'Rielly publications) states there is "BEFORE, AFTER, FIRST, SECOND, THIRD" but I can only get FIRST and AFTER to work using MySQL 5.1

    That's why I came here for a different opinion.

    I think the book is wrong :(

    Try looking at MySQL refman page:
    http://dev.mysql.com/doc/refman/5.1/en/alter-ta...
    The location, if present, must be "FISRT" or "AFTER column", there is no other option.

    If the book is about MySQL 5.1 its really wrong, but isn t it about ANSI SQL or anything else?

    "...with a datatype of VARCHAR(80), use the..." then you say "...ADD email VARCHAR(60)" what i'm getting at here is 80 then 60. small typo.

    @KG - SQL comes in many flavors. PregreSQL and MySQL and MS SQLServer all use slightly different variations on SQL, with varying support for various language constructs. I can only assume they are all derived from some original SQL language specification.
