How Do I Access Data from RowDataPacket Objects in Node.js MySQL Queries?

Accessing RowDataPacket Objects in Node.js

When querying a local MySQL database, you may encounter a situation where you need to access the results, stored in an array called 'rows'. These results are RowDataPacket objects, which allow you to retrieve both the values and keys from the query.

To access the values, you can simply use the object's property name, as seen in the console output:

console.log(row.user_id); // Output: 101

The RowDataPacket object itself is the constructor function that creates these objects, so you can access it using the constructor.name property:

console.log(row.constructor.name); // Output: RowDataPacket

If the result array contains multiple RowDataPacket objects, you would use row[0] to access the first object's properties:

console.log(rows[0].user_id); // Output: 101

This approach using the object's properties gives you access to both the values and the keys of the RowDataPacket objects.
