php - 選択クエリのエラー

Question

as400 db2 iseries を使用していますが、データベースからデータを取得できません。for ループを使用すると正常に動作しますが、while ループを使用するとエラーが発生します。ここで、参照用にコードを更新します...

コード：

$database = 'xxxxxx';
$user = 'xxx';
$password = 'xxx';
$hostname = 'x.x.x.x';

 include('adodb.inc.php');

     $db = ADONewConnection('odbc');
     $dsn = "DRIVER={iSeries Access ODBC Driver};SYSTEM=$hostname;DATABASE=$database;";
     if($db->Connect($dsn,$user,$password)){
         $query = "SELECT * FROM IND0301F.XMAGLF0 WHERE XMCDMA='I01' AND XMCDUB=''"; 
         $res = odbc_exec($query); 
         while( $row = odbc_fetch_array($res) ) { 
             echo $row['XMARCD'];  exit;
          } 
     }


<?php // no direct access 
  //defined('_JEXEC') or die('Restricted access');
?>
<?php
 set_time_limit(0); 
  //echo "Current User is ". $uname=$_SESSION['username']; 
?>
<?php
$database = 'IND0301F';
$user = 'QUSER';
$password = 'QUSER';
$hostname = '10.10.0.30';
?>



<?php
     include('adodb.inc.php');

     $db = ADONewConnection('odbc');
     $dsn = "DRIVER={iSeries Access ODBC Driver};SYSTEM=$hostname;DATABASE=$database;";
     if($db->Connect($dsn,$user,$password)){
         $sql_count = "SELECT COUNT(*) FROM IND0301F.XMAGLF0 WHERE XMCDMA='I01' AND XMCDUB=''"; 
         $rs_count = $db->Execute($sql_count);
         $result_count = $rs_count->GetArray();
         $count_rd = $result_count[0][0];  
         $sql = "SELECT * FROM IND0301F.XMAGLF0 WHERE XMCDMA='I01' AND XMCDUB=''";
         $rs = $db->Execute($sql);
         if (!$rs) echo "<p>no records</p>";
         else 
             {
             $result = $rs->GetArray();
?>
