import java.sql.*;public class TestSql2000_bak{    public static void main(String[] args)    {        try        {            String sql = "USE [color=#FF0000]mydatabase [/color]"+            "EXEC sp_addumpdevice 'disk','[color=#00FF00]testBAK[/color]','C:\\tttt\\bak.dat' "+            "BACKUP DATABASE rbac TO [color=#00FF00]testBAK[/color]";            Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver")                    .newInstance();            System.out.println("数据库驱动程序注册成功！");            String url = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=northwind";            String user = "sa";            String password = "pwd";            Connection conn = DriverManager.getConnection(url, user, password);            System.out.println("数据库连接成功");            Statement stmt = conn.createStatement();            stmt.execute(sql);            System.out.println("备份成功");        } catch (Exception e)        {            e.printStackTrace();            System.out.println("数据库连接失败");        }    }}
