Using the latest PHP windows package (PHP 5.1.3-dev from 19 feb.) PDO throws an PDOException with message 'SQLSTATE[]: <<Unknown error>>: 0' when executing an SQL statement (UPDATE or DELETE) where the WHERE restriction matches zero records in an MSAccess database.

The following ext. are loaded in php.ini:

Using php-cgi.exe and IIS

Reproduce code:
Table 'test' description:
field 'user' text(50) | field 'role' text(50)
$situation = 1; //value can be 1 or 2

$DBPath = "d:\\webroot\\database\\pdobug.mdb";
$MSAccessDB = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb)};Dbq=".$DBPath.";");

$SQL1 = "INSERT INTO test VALUES( 'testuser','testrole');";
$SQL2 = "UPDATE test SET role='administrator' WHERE user='testuser' AND role='testrole';";
$SQL3 = "DELETE FROM test WHERE user='testuser';";

	case 1:
		$MSAccessDB->exec($SQL2); //ok
		$MSAccessDB->exec($SQL2); //error
	case 2:
		$MSAccessDB->exec($SQL3); //ok
		$MSAccessDB->exec($SQL3); //error

Expected result:
a blank page as output and changes to the database log:
- Always first a new row added.
- In situation 1: the new row changed.
- In situation 2: the new row deleted.

Actual result:
This is the error in in situation 1:

Fatal error:  Uncaught exception 'PDOException' with message 'SQLSTATE[]: <<Unknown error>>: 0  (SQLExecDirect[0] at ext\pdo_odbc\odbc_driver.c:230)' in D:\webroot\www\test\pdobug.php:20
Stack trace:
#0 D:\webroot\www\test\pdobug.php(20): PDO->exec('UPDATE test SET...')
#1 {main}
  thrown in D:\webroot\www\test\pdobug.php on line 20

The error in situation 2 is exacly the same, except line numbers etc. of course.
