Body
I have a small issue with making a friendship system database. now I have a table called friends let's say: table friends: <pre><code> you friend approve since _________________________________________________ wetube youtube 1 4-12-2012 facebook wetube 1 4-12-2012 </code></pre> and i have this query code to fetch the friends of user called wetube. <pre><code>mysql_query("SELECT f.* FROM friends f inner join users u on u.username = f.you WHERE f.friend = 'wetube' UNION ALL SELECT f.* FROM friends f inner join users u on u.username = f.friend WHERE f.you = 'wetube'"); </code></pre> now what I want exactly is how to fetch the friens of wetube and show it to him on his page. fixed: Finally I fixed the problem. so this is the table: <pre><code>CREATE TABLE IF NOT EXISTS `friends` ( `id` int(20) NOT NULL AUTO_INCREMENT, `you` varchar(255) NOT NULL, `friend` varchar(255) NOT NULL, `type` varchar(255) NOT NULL, `since` date NOT NULL, `message` text NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `id` (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=2 ; </code></pre> and this is the php code to fetch the user friends <pre><code><?php $username = $_SESSION['username']; $friends_sql = mysql_query("SELECT * FROM friends WHERE (friend = '$username' OR you = '$username') "); while($friends_row = mysql_fetch_assoc($friends_sql)){ if ($username == $friends_row['you']) { echo $friends_row['friend']." "; } elseif($username == $friends_row['friend']) { echo $friends_row['you']." "; } } ?> </code></pre> try it yourself it works 100%

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
