Node.JS Getting "Jdbc is not defined" when running code on Visual Studio Code

[Octopus]

Hello to all,
I am in the process of building a simple and small app using javascript and a remote MySql database, so i set up this project in Visual Studio Code:


The following code works perfectly when I run it under Google Appscript:

var port = 3306;
var dbName = "sql7621994";
var username = "sql7621994";
var password = "xxxxxxxxxx";
var server = "sql7.freemysqlhosting.net";

function xsomareg() {
  try {
    var url = 'jdbc:mysql://' + server + ':' + port + '/' + dbName;
    var conn = Jdbc.getConnection(url, username, password);
    var stmt = conn.createStatement();
    var guarda = stmt.executeQuery("SELECT SUM(valor) FROM registos");
    guarda.next();
    console.log(guarda.getDouble(1));
  } catch (err) {
    console.log('Failed with error: %s', err.message);
  }
}

THE PROBLEM: When I use it under Visual Studio Code (in the apps.js file) I get the message "Jdbc is not defined", as follows:

Using SqlTools extension, I am able to run the SELECT statement is VSC and get the correct result:



I am very new to this and probably making some mistake. So I will be grateful if someone please can give a hand on this.
