无法读取nodejs和mysql中未定义的属性'query‘

const mysql = require('mysql');

const connection = mysql.createConnection({
  host: 'localhost',
  user: 'your_username',
  password: 'your_password',
  database: 'your_database'
});

connection.connect((err) => {
  if (err) {
    console.error('Error connecting to database: ' + err.stack);
    return;
  }
  console.log('Connected to database with connection id ' + connection.threadId);
});

connection.query('SELECT * FROM users', (error, results, fields) => {
  if (error) {
    console.error('Error executing query: ' + error.stack);
    return;
  }
  console.log('Query results:', results);
});
