Помогите с MySQL

Сам ни разу не программист, понадобилось немного модифицировать код php-скрипта.

Кусок кода 1
if ( (!isset($new_products_category_id)) || ($new_products_category_id == '0') ) {
    $new_products_query = tep_db_query("select p.products_id, p.products_image, p.products_tax_class_id, if(s.status, s.specials_new_products_price, fp.products_price) as products_price from " . TABLE_FIXED_PRICES . " fp, " . TABLE_PRODUCTS . " p left join " . TABLE_SPECIALS . " s on p.products_id = s.products_id where fp.product_id = p.products_id and fp.code = '" . $currency . "' and products_status = '1' order by p.products_date_added desc limit " . MAX_DISPLAY_NEW_PRODUCTS);
  } else {
    $new_products_query = tep_db_query("select distinct p.products_id, p.products_image, p.products_tax_class_id, if(s.status, s.specials_new_products_price, fp.products_price) as products_price from " . TABLE_FIXED_PRICES . " fp, " . TABLE_PRODUCTS . " p left join " . TABLE_SPECIALS . " s on p.products_id = s.products_id, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c, " . TABLE_CATEGORIES .

"' and fp.product_id = p.products_id and p.products_status = '1' order by p.products_date_added desc limit " . MAX_DISPLAY_NEW_PRODUCTS);
  }
  $row = 0;
  $col = 0;
  $info_box_contents = array();
  while ($new_products = tep_db_fetch_array($new_products_query)) {
    $info_box_contents[$row][$col] = array('align' => 'center',
                                           'params' => 'class="smallText" width="33%" valign="top"',
                                           'text' => '<a href="' . tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $new_products['products_id']) .

'</a><br><a href="' . tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $new_products['products_id']) . '">' . $new_products['products_name'] . '</a><br>' . $currencies->display_price($new_products['products_price'], tep_get_tax_rate($new_products['products_tax_class_id'])));

Это два варианта одного и того же скрипта. Во второй врезке есть запрос products_name из TABLE_PRODUCTS_DESCRIPTION — как правильно этот запрос ввернуть в первый кусок кода?
а второй вариант не работет? вообще - схема таблиц в таких случаях нужна…
systemd должен умереть.
