mysql - 从 mysql 4.0 导入 .sql 文件时出现 SQL 语法错误

我正在尝试将使用 mysql 4.0 创建的 .sql 文件导入到最新版本的 mysql 中，但收到了有关以下代码的语法错误:

CREATE TABLE edgemap (
  senderid int(10) unsigned default NULL,
  recipientid int(10) unsigned default NULL,
  messageid int(10) unsigned default NULL,
  messagedt timestamp(14) NOT NULL,
  reciptype enum('bcc','cc','to') default NULL,
  subject varchar(255) default NULL,
  KEY senderid (senderid,recipientid),
  KEY messageid (messageid),
  KEY messagedt (messagedt),
  KEY senderid_2 (senderid),
  KEY recipientid (recipientid)
) ENGINE=MyISAM;

我收到的错误消息是:

ERROR 1064 (42000) at line 255752: 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 '(14) NOT NULL,
  reciptype enum('bcc','cc','to') default NULL,
  subject varchar' at line 5

任何帮助将不胜感激!
