String connectDB = "jdbc:jtds:sqlserver://172.16.1.15:1433;DatabaseName=YanBu";// 连接字符串换成这个

                try {
                    Class.forName("net.sourceforge.jtds.jdbc.Driver");//加载驱动换成这个
                } catch (Exception e) {
                    e.printStackTrace();
                    System.out.println("加载数据库引擎失败");
                    System.exit(0);
                }
                System.out.println("数据库驱动成功");

                try {
                    String user = "sa";
                    String password = "sa";
                    Connection con = DriverManager.getConnection(connectDB, user, password);// 连接数据库对象
                    System.out.println("连接数据库成功");

                    int i = 1;

                    Statement statement = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
                    ResultSet resultSet = statement.executeQuery("select * from MaxSNs where Name = ‘质检单号‘");
                    while (resultSet.next()) {//<code>ResultSet</code>最初指向第一行
                        System.out.println(resultSet.getInt("SN"));//输出第n行，列名为“test_id”的值
                        i += resultSet.getInt("SN");
                        resultSet.updateInt("SN",i);
                        resultSet.updateRow();
                    }

                    resultSet.close();
                    statement.close();

                } catch (SQLException e) {
                    e.printStackTrace();
                }
