After getting lastest svn trunk I got the exception:

Fatal error: Uncaught exception 'Zend_Db_Statement_Exception' with message 'SQLSTATE[HYC00]: Optional feature not implemented' in R:\library\Zend\Db\Statement\Pdo.php:167 Stack trace:

Checking out the error I found that in issue 2101 there was a change done (http://framework.zend.com/code/browse/…), this change generates the problem, after commenting the line:

//while ($this->_stmt->nextRowset()) {}

the problem was solved.
