感謝beansoft提供的《MyEclipse 6 Java 開(kāi)發(fā)中文教程》，使我受益匪淺。
1、首先，當(dāng)然要準(zhǔn)備JDBC驅(qū)動(dòng)啦
可以到mysql官方網(wǎng)站下載mysql-connector-java-5.1.6-bin.jar
2、
CREATE TABLE `student` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(200) NOT NULL,
`password` varchar(20) NOT NULL,
`age` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=9 DEFAULT CHARSET=gbk;
