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:

    severity: 0,
    code: 5014,
    sqlState: 'HY000',
    msg: 'Wrong number of fields in row being inserted'
  }
}

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?

问题是我使用的是 product.name 而不是 product.productName。结论,使用打字稿。:)
