 New Comment:

This is a serious bug in the PDO. Look at the example more closely.
Variable $res has nothing to do with errenous query.

Running errenous query and not expecting exception is bogus.

Description:
------------
Iteration using foreach throws "previous" and irrelevant exception.
Exception is throwed after last iteration.

Test script:
---------------
$conn = new PDO("mysql:dbname=test");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$res = $conn->query('SELECT * FROM categories');

try {
	$conn->query('ERROR');
} catch (PDOException $e) { // exception is catched
}

foreach ($res as $k => $v); // now is throwed exception $e !!!


Expected result:
----------------
do nothing



------------------------------------------------------------------------
