1 資料庫準備

（1）建立一個名為mytest的資料庫

（2）建立表

CREATE TABLE `t_user` ( 
`USER_ID` int(11) NOT NULL AUTO_INCREMENT, 
`USER_NAME` char(30) NOT NULL, 
`USER_PASSWORD` char(10) NOT NULL, 
PRIMARY KEY (`USER_ID`), 
KEY `IDX_NAME` (`USER_NAME`) 
)ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8

（3）插入資料

INSERT INTO t_user (USER_ID, USER_NAME,USER_PASSWORD) VALUES (1, 'Zhang San', '654321');
INSERT INTO t_user (USER_ID, USER_NAME,USER_PASSWORD) VALUES (2, 'Li Si', '123456');
