Thanks for all the replies. Jochem, thank you for this code, which will
take me all night to understand (though I bet it works). I also note
that SELECT DISTINCT worked here, too
Also as many of you noticed before me, the art_id was in there as a fly
in the ointment.
by that statement I ment the exact same thing Jochem ment in his 2nd
part; I have NO idea why you're selecting *ANYTHING* from the arts
table... it's *useless* if you don't need the data...
Thanks all!

This is something dumb I am doing but:
Trying to pull all names of publishers in db. This sql:
its a mysql question in disguise, maybe...:
SELECT DISTINCT art.art_id,art.publisher_id,publisher.publisher_name
FROM art
LEFT JOIN publisher
ON publisher.publisher_id=art.publisher_iduse,
on the other hand if you want to pull every article
from the DB then that won't do it. maybe you
need to be extracting the name of the article instead/aswell?
on the other hand if you are trying to display a list of
publishers, why are you selecting from the arts table?
SELECT p.publisher_id,p.publisher_name
FROM publisher p ORDER BY p publisher_id DESC
(maybe you only want to show publishers with listed 'art's?)
what does this do for you?:
SELECT COUNT(a.art_id) as art_count,a.publisher_id,p.publisher_name
FROM art a, publisher p
WHERE p.publisher_id=a.publisher_id
AND art_count > 0
GROUP BY a.publisher_id
SELECT art.art_id,art.publisher_id,publisher.publisher_name,
FROM art
LEFT JOIN publisher
ON publisher.publisher_id=art.publisher_id
pulls (in phpmyadmin) four rows:
artID pubID Publisher_name
1 7 The New York Times: Sunday Styles
2 3 The New York Sun
3 2 Metro NY
4 3 The New York Sun
I'm trying to make a sidebar which will make links to each unique
publisher name:
and/or something like.:
<?php
// $result = DB::doMagic();
$seenAlready = array();
$templet = '<ul class="sidebar-menu"><a class="img-link" href="'
. $_SERVER['PHP_SELF']
. '?p=%1$s" title="%2$s">%2$s</a></ul>';
while ($cartoon = mysql_fetch_assoc($result)) {
if (in_array($cartoon['publisher_id'], $seenAlready))
continue;
$seenAlready[] = $cartoon['publisher_id'];
$pub_sidebar[] = sprintf($templet,
$cartoon['publisher_id'],
$cartoon['publisher_name']);
}
while ($cartoon = mysql_fetch_assoc($result)) {
$pub_sidebar[] = "<ul class='sidebar-menu'><a class='img-link'
href='{$_SERVER['PHP_SELF']}?p={$cartoon['publisher_id']}'
title=\"{$cartoon['publisher_name']}\">{$cartoon['publisher_name']}</a></ul>";
}
This prints:
The New York Times: Sunday Styles
The New York Sun
Metro NY
The New York Sun
I'd like to stop the NY Sun from appearing twice! What have i missed
here?
Thanks in advance!
