ご回答ありがとうございます。
SC_Product.phpのalldtlSQLに上記内容の記述がないのです。
SC_DB_DBFactory.phpにalldtlSQLが下記記述であるのですがどこにカラム追加すればよいかが分かりません。




public function alldtlSQL($where_products_class = '')
{
if (!SC_Utils_Ex::isBlank($where_products_class)) {
$where_products_class = 'AND (' . $where_products_class . ')';
}
/*
* point_rate, deliv_fee は商品規格(dtb_products_class)ごとに保持しているが,
* 商品(dtb_products)ごとの設定なので MAX のみを取得する.
*/
$sql = <<< __EOS__
(
SELECT
dtb_products.*
,T4.product_code_min
,T4.product_code_max
,T4.price01_min
,T4.price01_max
,T4.price02_min
,T4.price02_max
,T4.stock_min
,T4.stock_max
,T4.stock_unlimited_min
,T4.stock_unlimited_max
,T4.point_rate
,T4.deliv_fee

,dtb_maker.name AS maker_name
FROM dtb_products
INNER JOIN (
SELECT product_id

WHERE del_flg = 0 $where_products_class
GROUP BY product_id
) AS T4
ON dtb_products.product_id = T4.product_id
LEFT JOIN dtb_maker

) AS alldtl
__EOS__;

return $sql;
}
