Using Mysql on Joomla 2.5. Here is my code. Works great except doesn't show results where no users (u) attached to team (t).
$query = "SELECT DISTINCT(t.id) as id,t.*, GROUP_CONCAT(DISTINCT ' ',MID(u.first_name,1,1) ,'.',u.last_name) as name
FROM #__bl_teams as t
LEFT JOIN (#__bl_teamcord as tc, #__users as u) ON(FIND_IN_SET(t.id,tc.teams)AND tc.u_id = u.id)
WHERE
t.id != 0
AND t.id != 1
AND ".$season_id." = t.s_id
GROUP BY t.id
ORDER BY t.t_name";
$db->setQuery($query);
$rows = $db->loadObjectList();
foreach($rows as $row){
echo $row->id.' - '.$row->name.'<br />';
}
