apa yang salah dengan kueri Magento ini?

Baru saja memutakhirkan ke 1.9.2.2 untuk situs web teman dan mengalami masalah ini, saya memasang tambalan berikut di file,

[magento/app/code/core/Mage/CatalogRule/Model/Action/Index/Refresh.php]

Saya tidak bisa mengatakan efek onflow apa yang mungkin ada dan pembaruan di masa mendatang harus berhati-hati untuk tidak melewatkan fitur ini jika file ini ditimpa, tentu saja, tetapi untuk memulai tambahkan baris:

'rules_hash'            => new Zend_Db_Expr('NULL'),

untuk membuat pernyataan pilih terlihat sebagai berikut:

$select = $this->_connection->select()
        ->from($indexSelect, array())
        ->joinInner(
            array(
                'dates' => $this->_connection->select()->union(
                    array(
                        new Zend_Db_Expr(
                            'SELECT ' . $this->_connection->getDateAddSql(
                                $this->_connection->fromUnixtime($time),
                                -1,
                                Varien_Db_Adapter_Interface::INTERVAL_DAY
                            ) . ' AS rule_date'
                        ),
                        new Zend_Db_Expr('SELECT ' . $this->_connection->fromUnixtime($time) . ' AS rule_date'),
                        new Zend_Db_Expr(
                            'SELECT ' . $this->_connection->getDateAddSql(
                                $this->_connection->fromUnixtime($time),
                                1,
                                Varien_Db_Adapter_Interface::INTERVAL_DAY
                            ) . ' AS rule_date'
                        ),
                    )
                )
            ),
            '1=1',
            array()
        )
        ->columns(
            array(
                'rule_product_price_id' => new Zend_Db_Expr('NULL'),
                'rule_date'             => 'dates.rule_date',
                'customer_group_id'     => 'customer_group_id',

        )

    return $select;
