I've left out the user table as this info is already available in $vbulletin->userinfo, so the JOIN is avoided -> lighter query.

PHP Code:

<?php 
if ($vbulletin->userinfo['usergroupid']==6) 
{
    $result = $vbulletin->db->query_read("SELECT * FROM test WHERE test_ID = " . $vbulletin->userinfo['userid']);
    while ($row = $vbulletin->db->fetch_array($result))
    {
        echo $row['test_name'];
    }
}
?>

Also, if there is only one record for ewach userid it could be simpilified to

PHP Code:

<?php 
if ($vbulletin->userinfo['usergroupid']==6 ) 
{
    $row = $vbulletin->db->query_first("SELECT * FROM test WHERE test_ID = " . $vbulletin->userinfo['userid']);
    echo $row['test_name'];
}
?>
