Question

这是我的SQL：

CREATE TABLE mytable (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `customer_id` int(10) NOT NULL,
  `token` varchar(100),
  `created_at` datetime,
  PRIMARY KEY (`id`),
  CONSTRAINT `FK_PASSWORD_RECOVERY_CUSTOMER` FOREIGN KEY (`customer_id`) REFERENCES `customer_entity` (`entity_id`) ON UPDATE CASCADE ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1

它总是给我：无法创建表'mytable'（错误号：150）SQL.sql

正如我对您的问题的评论中所述，您获得的错误与约束定义有关。然后，您应该检查proper syntax for the constraint。

我认为问题在于您没有为customer_id列编制索引。尝试索引它：

CREATE TABLE mytable (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `customer_id` int(10) NOT NULL,
  `token` varchar(100),
  `created_at` datetime,
  PRIMARY KEY (`id`),
  INDEX cust_id(customer_id), -- ADD THIS
  FOREIGN KEY (`customer_id`) 
      REFERENCES `customer_entity` (`entity_id`) 
      ON UPDATE CASCADE 
      ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

（作为预防措施和哑巴检查，确认customer_entity也是InnoDB表）

创建表时SQLSTATE [HY000]错误？
