Description:
------------
Getting PDO exception (SQLSTATE[HY000]: General error: 2036) when using aggregate function on PHP5 via PDO and MySQL5. (No problem when using MySQL4 or without PDO).

PHP 5.2.0RC2-dev
MySQL 5.0.19





Reproduce code:
---------------
// MySQL

CREATE TABLE `test` (
  `ids` int(11) NOT NULL,
  `value` int(11) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

-- 
-- Dumping data for table `test`
-- 

INSERT INTO `test` VALUES (10, 23);
INSERT INTO `test` VALUES (10, 13);

// PHP


$query = 'SELECT AVG(value) FROM test WHERE ids=10 GROUP BY ids';

$dbh = new PDO($dsn, $user, $password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$rs = $dbh->query($query);
$result = $rs->fetchAll(PDO::FETCH_ASSOC);
print_r($result);

Expected result:
----------------
Array
(
    [0] => Array
        (
            [AVG(value)] => 18.0000
        )

)


Actual result:
--------------
Fatal error:  Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 2036
