Question

我这里有一个非常奇怪的问题。我通过phpmyadmin导出一个查询然后当我使用mysql_query运行它时，我得到一个错误，说查询的语法不正确。

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 'CREATE TABLE IF NOT EXISTS `wp_cfs_events` ( `event_id` int(11) NOT NULL AUTO_' at line 14

使用phpmyadmin运行完全相同的查询。可能是什么问题？

这是SQL查询

CREATE TABLE IF NOT EXISTS `wp_cfs_certificates` (
  `certificate_id` varchar(8) DEFAULT NULL,
  `parent_name` varchar(45) NOT NULL,
  `address` varchar(45) NOT NULL,
  `phone_number` varchar(15) NOT NULL,
  `emergency_number` varchar(15) NOT NULL,
  `email` varchar(45) NOT NULL,
  `certificate_price` enum('40','50') NOT NULL,
  `certificate_order_time` datetime DEFAULT NULL,
  `is_used` tinyint(1) DEFAULT '0',
  UNIQUE KEY `certificate_id_UNIQUE` (`certificate_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

CREATE TABLE IF NOT EXISTS `wp_cfs_events` (
  `event_id` int(11) NOT NULL AUTO_INCREMENT,
  `event_name` varchar(60) DEFAULT NULL,
  `event_desc` varchar(2048) DEFAULT NULL,
  `event_date` date DEFAULT NULL,
  PRIMARY KEY (`event_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=6 ;

INSERT INTO `wp_cfs_events` (`event_id`, `event_name`, `event_desc`, `event_date`) VALUES
(1, 'Culture Night', 'all about culture', '2013-05-16'),
(2, 'Sports Night', 'all about sports', '2013-05-31'),
(3, 'Random Night', 'randomness overloaded', '2013-06-15'),
(4, 'Winter Fest', 'the awesome winter fest', '2013-11-20'),
(5, 'Archived Event', 'this event has been occured in past', '2013-04-02');

CREATE TABLE IF NOT EXISTS `wp_cfs_parents` (
  `parent_id` int(11) NOT NULL,
  `parent_name` varchar(60) DEFAULT NULL,
  PRIMARY KEY (`parent_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

CREATE TABLE IF NOT EXISTS `wp_cfs_registrations` (
  `registration_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `certificate_id` varchar(8) NOT NULL,
  `event_id` varchar(45) DEFAULT NULL,
  `parent_name` varchar(45) NOT NULL,
  `address` varchar(45) NOT NULL,
  `phone_number` varchar(15) NOT NULL,
  `emergency_number` varchar(15) NOT NULL,
  `email` varchar(45) NOT NULL,
  `child_name` varchar(45) DEFAULT NULL,
  `child_age` int(11) DEFAULT NULL,
  PRIMARY KEY (`registration_id`),
  UNIQUE KEY `certificate_id_UNIQUE` (`certificate_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

ALTER TABLE `wp_cfs_registrations`
  ADD CONSTRAINT `certificate_id` FOREIGN KEY (`certificate_id`) REFERENCES `wp_cfs_certificates` (`certificate_id`) ON DELETE NO ACTION ON UPDATE CASCADE;

因为mysql_query()不支持多个查询

在官方PHP文档中提到

mysql_query()向与指定link_identifier关联的服务器上的当前活动数据库发送唯一查询（不支持多个查询）。

从phpmyadmin导出的查询在PHP中使用mysql_query（）无效

这是SQL查询
