使用my exclipse对数据库进行操作(2)

二、增加

public static void main(String[] args) {
  //TODO Auto-generated method stub

//4.用户输入需要添加的项目
     Scanner sc = new Scanner(System.in);
     System.out.println("请输入你要添加的数据：");
     System.out.println("2.姓名");
     String two = sc.nextLine();
     System.out.println("3.性别");
     String three = sc.nextLine();
     System.out.println("4.年龄");
     int fore= Integer.parseInt(sc.nextLine());
     System.out.println("5.学校编码");
     int five= Integer.parseInt(sc.nextLine());

try {

//1.导入数据库并且链接

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

Connection conn = DriverManager.getConnection("jdbc:sqlserver://192.168.8.60;DataBaseName=School","sa","123456");

//3.写SQL语句

String sql= "insert into [Student] values(？，？，？，？)";

//2.取出数据库内容并以SQL形式展现

PreparedStatement stmt= conn.prepareStatement(sql);

stmt.setObject(1,two);

stmt.setObject(2,three);

stmt.setObject(3,fore);

stmt.setObject(4,five);

//5.判断是否添加成功

if(!stmt.execute()){

　　 System.out.println("数据添加成功");

}else{

System.out.println("数据添加没成功");

}

//6.关闭数据

if(!stmt.isClosed()){      stmt.close();     }     if(!conn.isClosed()){      conn.close();     }

} catch (ClassNotFoundException e1) {     // TODO Auto-generated catch block     e1.printStackTrace();    }catch (SQLException e) {     // TODO Auto-generated catch block     e.printStackTrace();    }                   }
