如何从nodejs中的SQLite object中提取查询字符串？

Question

How to extract the query string from a SQLite object in nodejs ?

For example if we have this:

import sqlite3 from 'sqlite3';
import { open } from 'sqlite';

const db = await open({
  filename: 'test.db',
  driver: sqlite3.Database
});

var ret = await db.get('SELECT * FROM `test` WHERE id=? AND foo=?', [100, 'bar']);

How can we achieve this:

SELECT * FROM `test` WHERE id="100" AND foo="bar"

I expect something like this to happen:

db.getQueryString();

es6 string replacement is supporet by node.js.

var my_id = 100
var my_var = 'bar';
var s = `SELECT * FROM `test` WHERE id="${my_id}" AND foo="${my_var}" `;
console.log(s);

But you should prepare your statements to make the secure like https://stackoverflow.com/a/49328621/5193536

Depending if ydo want the strings in the log to be used, for testing, you must add single quotes to the sting above, which the query makes automatically
