我使用新的 x-authentication 成功连接到本地 MySQL 服务器。我有一个具有以下架构(DDL)的产品表:
CREATE TABLE `products` (
`id` int unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(45) NOT NULL,
`description_he` text,
`description_en` text,
`display_name_he` varchar(45) DEFAULT NULL,
`display_name_en` varchar(45) DEFAULT NULL,
`image_path` varchar(255) DEFAULT NULL,
`price` smallint unsigned NOT NULL,
`is_visible` tinyint NOT NULL DEFAULT '1',
PRIMARY KEY (`id`),
UNIQUE KEY `id_UNIQUE` (`id`),
UNIQUE KEY `name_UNIQUE` (`name`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb3 COMMENT='contains information about products'
我尝试将以下 javascript 对象插入此表中:
Product {
productID: null,
productName: 'product2',
descriptionHE: 'תיאור המוצר',
descriptionEN: 'product description',
displayNameHE: 'מוצר',
displayNameEN: 'Product',
imagePath: 'assets/images/facebook-512.png',
price: 400
}
我使用以下代码做到了这一点:
let table = this.session.getSchema('...').getTable('products')
return table.insert(
'id', 'name', 'description_he', 'description_en', 'display_name_he', 'display_name_en', 'image_path', 'price', 'is_visible')
.values(
5,
product.name,
product.descriptionHE,
product.descriptionEN,
product.displayNameHE,
product.displayNameEN,
product.imagePath,
product.price,
1)
.execute()
.catch((err) => {
console.log(err);
})
这会捕获以下错误:

}
}
我尝试使用参数并稍微简化表模式,但我还找不到错误。您知道如何调试发送到 SQL 服务器的查询以找出失败的原因吗?
