You can do this in way:

$qx=mysql_query("SELECT ORCASENO,ORORDNO From order_break WHERE ORCASENO='$bcode' AND ORDEST='$dest'");

$array = array();
while($rx=mysql_fetch_array($qx))
   $array[] = $rx['ORORDNO'];

if (count(array_unique($array)) > 1)
   echo 'Error';
else
{
   foreach($array as $value)
      echo $value;
}
