Question

这是我的产品表：

CREATE TABLE `products` (
  `idproduct` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(45) NOT NULL,
  `description` text NOT NULL,
  `price` double unsigned NOT NULL,
  `shipping` double unsigned DEFAULT NULL,
  `condition` int(10) unsigned NOT NULL,
  `returns` int(10) unsigned NOT NULL,
  `date` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `image` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`idproduct`)
) ENGINE=InnoDB AUTO_INCREMENT=16 DEFAULT CHARSET=utf8

这是我的product_categories表

CREATE TABLE `products_subcategories` (
  `idproduct_category` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `idproduct` int(10) unsigned NOT NULL,
  `idsubcategory` int(10) unsigned NOT NULL,
  PRIMARY KEY (`idproduct_category`),
  KEY `products_categories_products_idx` (`idproduct`),
  KEY `products_categories_categories_idx` (`idsubcategory`),
  CONSTRAINT `products_subcategories_products` FOREIGN KEY (`idproduct`) REFERENCES `products` (`idproduct`) ON DELETE CASCADE ON UPDATE CASCADE,
  CONSTRAINT `products_subcategories_subcategories` FOREIGN KEY (`idsubcategory`) REFERENCES `subcategories` (`idSubcategory`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8

我试图搜索这样的产品：

Select products.* from products 
  INNER JOIN products_subcategories 
    ON products.idproduct = products_subcategories.idproduct  
  WHERE name LIKE '%p%'

但它只返回一行..没有内连接它会返回更多行

MySQL只返回一个结果
