语句如下：alter table tableName engine=InnoDB;

用到的表

复制代码 代码如下:

CREATE TABLE IF NOT EXISTS `test` (

`id` int(10) NOT NULL auto_increment,

`websitename` varchar(200) character set utf8 NOT NULL,

`websiteurl` varchar(200) character set utf8 NOT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

第二不就是如果和添加事物：

复制代码 代码如下:

<?php

$con = mysql_connect("localhost", "root", "vertrigo");

//开始事务

mysql_db_query("mysqlnew","BEGIN");

$insertSql ="insert into test(websitename,websiteurl)values('查字典教程网','http://www.jb51.net')";//该记录插入数据库

mysql_db_query("mysqlnew",$insertSql);

$insertSql ="insert into test(websitename,websiteurl)values('百度','http://www.baidu.com')";//该记录插入数据库

mysql_db_query("mysqlnew",$insertSql);

//结束事务事务

mysql_db_query("mysqlnew","COMMIT");

//开始事务

mysql_db_query("mysqlnew","BEGIN");

$insertSql ="insert into test(websitename,websiteurl)values('google','http://www.google.com.hk')";//该记录不插入数据库

mysql_db_query("mysqlnew",$insertSql);

//结束事务事务

mysql_db_query("mysqlnew","ROLLBACK");

//开始事务

mysql_db_query("mysqlnew","BEGIN");

$insertSql ="insert into test(websitename,websiteurl)values('bing','http://www.bing.com')";//该记录不插入数据库

mysql_db_query("mysqlnew",$insertSql);

?>

插入的数据

id websitename websiteurl
