Selecht from multiple databases PHP

Excuse my bad English

But I need this to work:

<? 
$media2 = mysql_query("SELECT id,content1,page FROM database WHERE page='website'") or die (mysql_error());
$media3 = mysql_query("SELECT id,text FROM db") or die (mysql_error());
if($spelen2 = mysql_fetch_assoc($media2)) 
while ($spelen3 = mysql_fetch_assoc($media3)); {
?>

<?
    if(empty($spelen2['content1']))
    {
     echo'';
    } else { 
     echo'Something';
    }
    ?>

<? } ?>

I want if empty to show all items from db. If not, show content from datbase. I can't seem to make it work.
