This may be a dumb question, but did you actually fetch the db query's results and put them in
$row before trying to use $row? In MySQL you could do something like:
$query = "select * from my_table";
$result = mysql_query($query);
$row = mysql_fetch_array($result); //this statement would need to be inside of a loop if there is
more than one result
