MYSQL#1064错误无法找到原因

我在从XAMPP运行的mysql上运行以下查询

SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0;
SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0;
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='TRADITIONAL';

DROP SCHEMA IF EXISTS htmlProject;
CREATE SCHEMA htmlProject;
USE htmlProject;

  actor_id SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT,
  actor_name VARCHAR(50) NOT NULL,

  PRIMARY KEY  (actor_id),
 )ENGINE=InnoDB DEFAULT CHARSET=utf8;

  CONSTRAINT `fk_tags_files` FOREIGN KEY (files_id) REFERENCES FILES (files_id) ON DELETE RESTRICT ON UPDATE CASCADE
 )ENGINE=InnoDB DEFAULT CHARSET=utf8;




SET SQL_MODE=@OLD_SQL_MODE;
SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS;
SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS;

但我仍然在下面的行中得到一个错误1064

我完全不知道为什么会发生这种情况，尽管我以前写过类似的查询，但绝对没有此类错误。什么事让我注意不到了？

你漏掉了一个逗号：

CREATE TABLE FILESTAG (
 files_tag_id SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT,
 tag_id SMALLINT UNSIGNED NOT NULL,
 files_id SMALLINT UNSIGNED NOT NULL   <---- Add comma here

创建表文件标签(
文件\u标记\u id SMALLINT无符号非空自动增量，
tag_id SMALLINT UNSIGNED NOT NULL，
