#1064 - 您的 SQL 语法 '(14) NOT NULL, `ID_MEMBER` mediumint(8) unsigned NOT NULL default '0', `ip` ' 在第 3 行有错误

Question

我收到此错误：

#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 '(14) NOT NULL, 
`ID_MEMBER` mediumint(8) unsigned NOT NULL default '0', `ip` ' at line 3

当我运行这个脚本时：

  CREATE TABLE IF NOT EXISTS `MVElog_online` (
  `session` varchar(32) NOT NULL default '0',
  `logTime` timestamp(14) NOT NULL,
  `ID_MEMBER` mediumint(8) unsigned NOT NULL default '0',
  `ip` int(10) unsigned NOT NULL default '0',
  `url` text NOT NULL,
  PRIMARY KEY  (`session`),
  KEY `logTime` (`logTime`),
  KEY `ID_MEMBER` (`ID_MEMBER`)
) ENGINE=MyISAM;

错误是什么意思，我做错了什么？

Answer 1

timestamp 不应该有长度，（它是 timestamp 而不是 timestamp(14)）

CREATE TABLE IF NOT EXISTS `MVElog_online` (
  `session` varchar(32) NOT NULL default '0',
  `logTime` timestamp NOT NULL,                 -- HERE
  `ID_MEMBER` mediumint(8) unsigned NOT NULL default '0',
  `ip` int(10) unsigned NOT NULL default '0',
  `url` text NOT NULL,
  PRIMARY KEY  (`session`),
  KEY `logTime` (`logTime`),
  KEY `ID_MEMBER` (`ID_MEMBER`)
) ENGINE=MyISAM;
