Description:
------------
If PDO_MSSQL PDOStatement is called 2 times and the first returned no result than second one return strange result.

PDO_MYSQL works fine.

Tested on Apache and IIS

Reproduce code:
---------------
$pdo = new PDO("mssql:host=[host];dbname=[base]",[user],[pass]);

$sth = $pdo->prepare("SELECT id FROM sometable WHERE id=:parentId");

$sth->execute(array(':parentId'=>1));
//or
//$sth->bindValue(':parentId',1,PDO::PARAM_INT);
$res1 = $sth->fetchAll();
$sth->closeCursor();

$sth->execute(array(':parentId'=>2));
//or
//$sth->bindValue(':parentId',2,PDO::PARAM_INT);
$res2 = $sth->fetchAll();
$sth->closeCursor();

Expected result:
----------------
$res1 = array[0] //empty
$res2 = array[
  0 = array['value' => 3]
  1 = array['value' => 6]
]

Actual result:
--------------
$res1 = array[0] //empty
$res2 = array[
  0 = array['[]' => null]
  1 = array['[]' => null]
]

Statetment should be:
$sth = $pdo->prepare("SELECT value FROM sometable WHERE id=:parentId");

I couldn't connect to MSSQL so I've exchanged ntwdblib.dll (v.7.00.839) to (v.8.00.194).

No result is:
$res1 = array[0] //empty
$res2 = array[
  0 = array['[]' => null, 0 => null]
  1 = array['[]' => null, 0 => null]
]

( [] = ASCII 0x11 )

and should be:
$res2 = array[
  0 = array['value' => 3, 0 => 3]
  1 = array['value' => 6, 0 => 6]
]

Tried to reproduce with code in trunk, returns expected results.

$db->query("create table test (id int not null primary key)");
$db->query("insert into test(id) values(2)");

$sth = $db->prepare("SELECT id FROM test WHERE id=:parentId");

$sth->execute(array(':parentId'=>1));
$res1 = $sth->fetchAll();
var_dump($res1);

$sth->execute(array(':parentId'=>2));
$res2 = $sth->fetchAll();
var_dump($res2);


array(0) {
}
array(1) {
  [0]=>
  array(2) {
    ["id"]=>
    string(1) "2"
    [0]=>
    string(1) "2"
  }
}
