执行mysql脚本报错1064 - You have an error in your SQL syntax;

Navicat中，运行SQL语句出现如下报错：

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 '(6) DEFAULT NULL,
  `is_superuser` tinyint(1) NOT NULL,
  `username` varchar(1' at line 4

SQL脚本如下：

DROP TABLE IF EXISTS auth_user;
CREATE TABLE auth_user (
  id int(11) NOT NULL AUTO_INCREMENT,
  password varchar(128) NOT NULL,
  last_login datetime DEFAULT NULL,
  is_superuser tinyint(1) NOT NULL,
  username varchar(150) NOT NULL,
  first_name varchar(150) NOT NULL,
  last_name varchar(150) NOT NULL,
  email varchar(254) NOT NULL,
  is_staff tinyint(1) NOT NULL,
  is_active tinyint(1) NOT NULL,
  date_joined datetime NOT NULL,
  PRIMARY KEY (id),
  UNIQUE KEY username (username)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

【解决方案】:
mysql关键字问题，需要用 ` 转义,将SQL语句改成如下则执行成功

DROP TABLE IF EXISTS `auth_user`;
CREATE TABLE `auth_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `password` varchar(128) NOT NULL,
  `last_login` datetime DEFAULT NULL,
  `is_superuser` tinyint(1) NOT NULL,
  `username` varchar(150) NOT NULL,
  `first_name` varchar(150) NOT NULL,
  `last_name` varchar(150) NOT NULL,
  `email` varchar(254) NOT NULL,
  `is_staff` tinyint(1) NOT NULL,
  `is_active` tinyint(1) NOT NULL,
  `date_joined` datetime NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `username` (`username`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
