    Default need help with cfquery

    This should be an easy one ... unfortunately I am a n00b to sql and CF. I am
    trying to display a certain column in a table, the most recent one. I have a
    column row setup as an int value giving a new number on each submission. I want
    to display the highest number, but no that value itself. Basically I have a
    table with id and articletext, I want to display the articletext column that
    has the highest id number. Hope that makes sense. I know the attached code is
    completely wrong but I cannot figure out what function I need to use.

    I am trying to create a way that users can log in, create an article, and post
    it on the site, like a blog but not as advanced. This is my first big web
    programming db driven project. Thanks a lot for any help!



    <cfquery name="article" datasource="anti_sql">
    SELECT id, articletext, artcldate
    FROM articles
    HAVING id
    WHERE id=MAX(id)
    </cfquery>

    Default Re: need help with cfquery

    Now I want to display the articles previous to that. Is there any easy way to
    create a sql statement that displays the previous ID numbers. I know I can do
    this:

    SELECT id, articletext, artcldate, artclauthor, artclname
    FROM articles
    ORDER BY id DESC

    But that creates a jumbled mess like so: [url]http://mindaugas.us/show.cfm[/url]

    I would like to be able to dsiplay one article at a time. So I need something
    like this?

    SELECT id, articletext, artcldate, artclauthor, artclname
    FROM articles
    WHERE id=(SELECT LAST(id) FROM articles)

    but sql 2k doesn't have last I think, plus that would select the last one, I
    need the second to most recent.

    Sorry for the total n00b questions this is the first time I have done anything
    with db's. I am trying to get a head start in school and for my own benefit. I
    really appreciate any help. Links to good sql tutorials are good also ;)
