导包:jtds-1.2.2.jar public class DBUtil { /** * 获得数据库连接 * @return */ public static ConnectiongetConnection() { Connectionconn = null ; try { // 1. 加载驱动 Class. forName ( net.sourceforge.jtds.jdbc.Driver ); // 连接字符串 jdbc:jtd

导包:jtds-1.2.2.jar


publicclassDBUtil {

/**

* 获得数据库连接

* @return

*/

publicstatic ConnectiongetConnection() {

Connectionconn = null;

try {

// 1. 加载驱动

Class.forName("net.sourceforge.jtds.jdbc.Driver");

// 连接字符串"jdbc:jtds:sqlserver://IP:端口/数据库名";

final String url ="jdbc:jtds:sqlserver://127.0.0.1:1433/SuperDogMall";

// 登陆数据库账号

final String user ="sa";

// 登陆数据库密码

final String password ="123456";

conn= DriverManager.getConnection(url, user, password);

}catch(ClassNotFoundException e) {

e.printStackTrace();

}catch(SQLException e) {

e.printStackTrace();

}

return conn;

}

publicstatic void main(String[] args) {

System.out.println(DBUtil.getConnection());

}

}


部分建表和插入内容的SQL语句:

use SuperDogMall

--建立表userinfo

create tableuserinfo

( userIdvarchar(20)primary key,

userPassword varchar(20)not null,

userName varchar(20),

userEmail varchar(40),

userBirth datetime,

userAddress varchar(40),

userMoney int

)

select *from userinfo

insert intouserinfo values('zhizunbao','123','至尊宝','zhizunbao@supermall.com','1980-10-10','四川省九寨沟',50000)

insert intouserinfo values('ershixiong','123','二师兄','ershixiong@supermall.com','1981-11-14','山东省威海市',5000)

insert intouserinfo values('zixiaxianzi','123','紫霞仙子','zixiaxianzi@supermall.com','1991-11-14','四川省盘丝洞',5800)

insert intouserinfo values('niumowang','123','牛魔王','niumowang@supermall.com','1980-11-14','四川省牛头山',5100)

insert intouserinfo values('tieshan','123','铁扇公主','tieshan@supermall.com','1988-11-14','新疆省火焰山',15000)

create tableproduct

(

proId varchar(20)primary key,

proName varchar(20),

proType varchar(20),

proPrice float check(proPrice>=0),

proStore int check(proStore>=0),

proSales int check(proSales>=0),

proPicture varchar(60),

proDesc varchar(200)

)

select *from product

insert intoproduct values('p_001','狗不理包子','食物','5','3000','1000','','好吃')

insert intoproduct values('p_002','庆丰包子','食物','2','3000','1500','','好吃')

insert into product values('p_003','德园包子','食物','1','2000','1000','','好吃')



一些driver和url的写法:

oracle
driver="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@localhost:1521:数据库名"
sqlserver
driver="com.microsoft.jdbc.sqlserver.SQLServerDriver"
url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=数据库名"
mysql
driver="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/数据库名?[后接参数]"
db2
driver="com.ibm.db2.jdbc.app.DB2Driver"
url="jdbc:db2://localhost:5000/数据库名"
sybase
driver="com.sybase.jdbc.SybDriver"
url="jdbc:sybase:Tds:localhost:5007/数据库名"
