MySQL表字段名不能包含减号

往MySQL数据中插入数据时，一直提示SQL语法有错误（syntax error），检查了半天，原来是因为表名包含了减号。

原来的表结构：

CREATE TABLE IF NOT EXISTS `amazon-sellertransactions` (
  `record-insert-time` timestamp NOT NULL DEFAULT CURRENT-TIMESTAMP ON UPDATE CURRENT-TIMESTAMP,
  `record-id` int(10) unsigned NOT NULL AUTO-INCREMENT,
  `amazon-order-id` varchar(30) DEFAULT NULL,
  `merchant-id` varchar(30) DEFAULT NULL,
  `purchase-date` datetime DEFAULT NULL,
  `last-update-date` datetime DEFAULT NULL,
  `order-status` varchar(50)  DEFAULT NULL,
  `fulfillment-channel` varchar(20)  DEFAULT NULL,
  `sales-channel` varchar(50)  DEFAULT NULL,
  `shipments-service-level` varchar(50)  DEFAULT NULL,
  `order-total` varchar(30)  DEFAULT NULL,
  `buyer-name` varchar(50) DEFAULT NULL,
  `buyer-email` varchar(60) DEFAULT NULL,
  `number-items-shipped` varchar(10) DEFAULT NULL,
  `number-items-unshipped` varchar(10) DEFAULT NULL,
  `ship-city` varchar(50) DEFAULT NULL,
  `ship-state` varchar(50) DEFAULT NULL,
  `ship-postal-code` varchar(50) DEFAULT NULL,
  `ship-country` varchar(50) DEFAULT NULL,
  `ship-name` varchar(50) DEFAULT NULL,
  `ship-phone` varchar(30) DEFAULT NULL,
  `ship-address-line1` varchar(120) DEFAULT NULL,
  `payment-method` varchar(30) DEFAULT NULL,
  PRIMARY KEY (`Record`),
  UNIQUE KEY `amazon-order-id` (`amazon-order-id`)
)ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

这段SQL代码创建表是没有问题，但是在相关操作中却报语法错误，加上引号也不行，所以，只能修改表字段名，修改后的SQL代码如下：

CREATE TABLE IF NOT EXISTS `amazon_sellertransactions` (
  `record_insert_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  `record_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `amazon_order_id` varchar(30) DEFAULT NULL,
  `merchant_id` varchar(30) DEFAULT NULL,
  `purchase_date` datetime DEFAULT NULL,
  `last_update_date` datetime DEFAULT NULL,
  `order_status` varchar(50)  DEFAULT NULL,
  `fulfillment_channel` varchar(20)  DEFAULT NULL,
  `sales_channel` varchar(50)  DEFAULT NULL,
  `shipments_service_level` varchar(50)  DEFAULT NULL,
  `order_total` varchar(30)  DEFAULT NULL,
  `buyer_name` varchar(50) DEFAULT NULL,
  `buyer_email` varchar(60) DEFAULT NULL,
  `number_items_shipped` varchar(10) DEFAULT NULL,
  `number_items_unshipped` varchar(10) DEFAULT NULL,
  `ship_city` varchar(50) DEFAULT NULL,
  `ship_state` varchar(50) DEFAULT NULL,
  `ship_postal_code` varchar(50) DEFAULT NULL,
  `ship_country` varchar(50) DEFAULT NULL,
  `ship_name` varchar(50) DEFAULT NULL,
  `ship_phone` varchar(30) DEFAULT NULL,
  `ship_address_line1` varchar(120) DEFAULT NULL,
  `payment_method` varchar(30) DEFAULT NULL,
  PRIMARY KEY (`Record`),
  UNIQUE KEY `amazon_order_id` (`amazon_order_id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
