Description:
------------
PDO doesn`t throw Exception when querying a sql with syntax error as expected.

MySQL Client Version: 5.0.45
MySQL Server Version: 4.0.16

But if I connect to a MySQL5 server, it throws Exception correctly.

Same error happened in php-5.2.2

Reproduce code:
---------------
$dbt = new PDO("mysql:host=xxx;port=xxx;dbname=xxx",'xxx','xxx');
$dbt->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$a = $dbt->query("what happened?");

Expected result:
----------------
PDO should throw a Exception

Actual result:
--------------
nothing is throwed

Andrey, any ideas about this? Seems more like an issue outside PHP..

I also use PHP 5 and MySQL 4 and had the same problem. When I use PHPMyAdmin it says "Your PHP MySQL library version 5.0.18 differs from your MySQL server version 4.0.27. This may cause unpredictable behavior." This confirms the existence of the problem. It seems to be a well-known problem. Otherwise it could be useful to contact the developers of PHPMyAdmin to find out more about their experiences.

If the different client- and server-versions are simply not meant to be compatible and it isn't a bug, it seems useful to me to raise an E_WARNING or E_NOTICE. This could help a lot of people by warning them.
