  $conn=odbc_connect($dsn,'user','passwd');

  $query="call multiplerowsets";

    $result=odbc_exec($conn,$query);
    $row=odbc_fetch_array ($result); var_dump(odbc_next_result($result));
    $row=odbc_fetch_array ($result); var_dump(odbc_next_result($result));
    $row=odbc_fetch_array ($result); var_dump(odbc_next_result($result));
