Mysql 在SQL中创建表时出现语法错误

我正在尝试这个查询，尽管做了几次尝试，但在创建表调用时仍然出现语法错误。其他表创建得很好。。我不明白为什么

学生代码

  CREATE TABLE Student (
      `student_id` int NOT NULL AUTO_INCREMENT,
      `phone_number` varchar(50) NOT NULL,
      `name` varchar(50) NOT NULL,
      `school` varchar(50) NOT NULL,
      `class` varchar(50) NOT NULL,

      PRIMARY KEY (`student_id`)
    )

餐桌故事

    CREATE TABLE Stories (
      `story_id` int NOT NULL AUTO_INCREMENT,
      `story_name` varchar(50) NOT NULL,
      `number_questions` int NOT NULL,
      `file_name` varchar(100) NOT NULL,

      PRIMARY KEY (`story_id`)
    )

表格问题

    CREATE TABLE Questions (
      `question_id` int NOT NULL,
      `story_id` int NOT NULL,
      `file_name` varchar(100) NOT NULL,
      `concept_tested` varchar(100) NOT NULL,
      `difficuly` varchar(50) NOT NULL,
      `number_options` int NOT NULL,
      `correct_answer` int NOT NULL,
      `call_number` int NOT NULL,

      PRIMARY KEY (`question_id`,`story_id`),

      FOREIGN KEY (`story_id`)
      REFERENCES `Stories`(`story_id`)
      ON DELETE CASCADE
    )

点名

    CREATE TABLE Call (
      `call_id` int NOT NULL AUTO_INCREMENT,
      `student_id` int NOT NULL,
      `story_id` int NOT NULL,
      `question_id` int NOT NULL,
      `call_number` int NOT NULL,
      `total_number` int NOT NULL,

      PRIMARY KEY (`call_id`),

      FOREIGN KEY (`student_id`)
      REFERENCES `Student`(`story_id`)
      ON DELETE CASCADE,

      FOREIGN KEY (`story_id`)
      REFERENCES `Stories`(`student_id`)
      ON DELETE CASCADE,

      FOREIGN KEY (`question_id`)
      REFERENCES `Stories`(`question_id`)
      ON DELETE CASCADE
    )

这是我的错误：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Call ( `call_id` int NOT NULL AUTO_INCREMENT, `student_id` int NOT NULL, ' at line 1

我已经试着编辑我的代码并检查了好几次，但问题仍然没有解决

我解决了问题

它是：

CREATE TABLE `Call` (
  `call_id` int NOT NULL AUTO_INCREMENT,
  `student_id` int NOT NULL,
  `story_id` int NOT NULL,
  `question_id` int NOT NULL,
  `call_number` int NOT NULL,
  `total_number` int NOT NULL,

  PRIMARY KEY (`call_id`),

  FOREIGN KEY (`student_id`)
  REFERENCES `Student`(`student_id`)
  ON DELETE CASCADE,

  FOREIGN KEY (`story_id`)
  REFERENCES `Stories`(`story_id`)
  ON DELETE CASCADE,

  FOREIGN KEY (`question_id`)
  REFERENCES `Questions`(`question_id`)
  ON DELETE CASCADE
)

我发现必须满足这些条件才能不出现错误150：

这两个表必须是ENGINE=InnoDB。（可以是其他：ENGINE=MyISAM也可以工作）

这两个表必须具有相同的字符集

父表中的PK列和FK列必须是相同的数据类型

父表中的PK列和FK列（如果它们具有定义排序规则类型）必须具有相同的排序规则类型

如果外键表中已有数据，则FK列值必须与父表PK列中的值匹配

并且子表不能是临时表

希望这有帮助

像这样试试

CREATE TABLE Questions (
  `call_id` int NOT NULL AUTO_INCREMENT,
  `student_id` int NOT NULL,
  `story_id` int NOT NULL,
  `question_id` int NOT NULL,
  `call_number` int NOT NULL,
  `total_number` int NOT NULL,

  PRIMARY KEY (`call_id`),

  FOREIGN KEY (`student_id`)
  REFERENCES `Student`(`story_id`)
  ON DELETE CASCADE,

  FOREIGN KEY (`story_id`)
  REFERENCES `Stories`(`student_id`)
  ON DELETE CASCADE,

  FOREIGN KEY (`question_id`)
  REFERENCES `Stories`(`question_id`)
  ON DELETE CASCADE
)ENGINE=MYISAM CHARACTER SET UTF8;

看看

是mysql还是sql server？不能两者同时存在。。。并用你得到的错误更新问题。语法错误并不是您得到的全部信息。是否显示语法错误的错误消息？mysql的那些记号。。不是sql server。我认为op只是有点混乱。@MarcinJuraszek我已经编辑添加了我的错误，你有什么建议吗？@VigneshKumar我正在使用InnoDB
