RowDataPacket to array

Converting RowDataPacket to Array

As a web developer, I have come across situations where I needed to convert the RowDataPacket object to an array. This usually happens when working with databases in Node.js.

Using the built-in 'mysql' module

If you are using the 'mysql' module in Node.js, you can use the 'mysql2' package to convert the RowDataPacket object to an array.

const mysql = require('mysql2');
const connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: '',
  database: 'test'
});

connection.query('SELECT * FROM users', (error, results, fields) => {
  if (error) throw error;
  const usersArray = JSON.parse(JSON.stringify(results));
  console.log(usersArray);
});

In the above code, we are using the JSON.parse() and JSON.stringify() methods to convert the RowDataPacket object to an array. This method is straightforward and works well in most cases.

Using the 'mysql2' module

The 'mysql2' module provides a more efficient way of converting the RowDataPacket object to an array.

const mysql = require('mysql2/promise');
const connection = await mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: '',
  database: 'test'
});

const [rows, fields] = await connection.execute('SELECT * FROM users');
console.log(rows);

In this example, we are using the execute() method provided by the 'mysql2' module to execute the SQL query and retrieve the results as an array.

• Option 1: Use JSON.parse() and JSON.stringify() methods to convert RowDataPacket object to array.
• Option 2: Use 'mysql2' module to execute the SQL query and retrieve the results as an array.
