Question

我有一个产品表，如下所示

CREATE TABLE `tbl_store_products` (
     `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
     `store_id` int(10) unsigned NOT NULL,
     `is_featured` tinyint(1) unsigned NOT NULL DEFAULT '0',
     `title` varchar(100) COLLATE utf8mb4_unicode_ci NOT NULL,
     `description` text COLLATE utf8mb4_unicode_ci NOT NULL,
     `promotion_sale`  tinyint(1) unsigned NOT NULL DEFAULT '0',
     `current_price` int(10) unsigned NOT NULL,
     `original_price` int(10) unsigned NOT NULL,
     `parent_category` int(10) unsigned NOT NULL,
     `sub_parent_category` int(10) unsigned NOT NULL,
     `child_category` int(10) unsigned NOT NULL,
     `instock_quantity` int(10) unsigned NOT NULL,
     `sold_quantity` int(10) unsigned NOT NULL DEFAULT '0',
     `list_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
     `reviewed` tinyint(1) NOT NULL DEFAULT '0',
     PRIMARY KEY (`id`),
     KEY `store_id` (`store_id`),
     KEY `parent_cat` (`parent_category`),
     KEY `sub_parent_cat` (`sub_parent_category`),
     KEY `category` (`child_category`),
     FULLTEXT KEY `product_title` (`title`)
    ) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

如你所见，我有5个指数。其中3个是产品类别。我这样做是为了使产品在父类别，子类别和子类别中快速可用。类别深度始终为3。

例如，如果标题为女性时尚高跟鞋的产品位于Fashion > Women Shoes > Heels

目前，当用户点击面包屑

中的任何链接时，我正在使用这些查询来获取产品

//Heels category id = 10
SELECT title, current_price, description FROM tbl_store_products WHERE category = 10

或

//Women Shoes category id = 8
SELECT title, current_price, description FROM tbl_store_products WHERE sub_parent_category = 8

或

//Fashion category id = 4
SELECT title, current_price, description FROM tbl_store_products WHERE parent_category = 4

我发现各级别的产品都很好。但我觉得我创造了太多指数。任何人都可以建议我这样做的更好方法。如果有人能告诉我关于我桌子的其他问题的其他建议，我将不胜感激。谢谢！

具有MyQSL类别的产品的数据库架构？
