Description:
------------
data not retreive when second parameter is column name (not index)

Therefore
      db2_result($stmt, 1) is work

      db2_result($stmt, 'breed') does not work

 

Reproduce code:
---------------
<?php
$sql = 'SELECT name, breed FROM animals WHERE weight < ?';
$stmt = db2_prepare($conn, $sql);
db2_execute($stmt, array(10));
while (db2_fetch_row($stmt)) {
    $name = db2_result($stmt, 0);
    $breed = db2_result($stmt, 'breed');
    print "name=$name breed=$breed";
}
?>

Expected result:
----------------
name=Tom    breed=cat

Actual result:
--------------
name=Tom    breed=
