How Do I Access Data from a MySQL Query Result Array in Node-webkit?

Accessing Data from a MySQL Query Result Using Node-webkit

In desktop applications developed with Node-webkit, retrieving data from a MySQL database is often a necessity. When executing queries and storing the results in an array, it can be challenging to access the data within.

Consider the following array of RowDataPacket objects, resulting from a query:

[RowDataPacket {user_id: 101, ActionsPerformed: 20},
 RowDataPacket {user_id: 102, ActionsPerformed: 110},
 RowDataPacket {user_id: 104, ActionsPerformed: 3}]

To retrieve the values, follow these steps:

Step 1: Understanding the RowDataPacket Object

Contrary to its name, RowDataPacket is the constructor function for a regular object. This means you can access the stored data using object notation.

Step 2: Accessing Object Values

To access the user_id or ActionsPerformed values, use the following syntax:

row["user_id"] // where row is one of the retrieved RowDataPacket objects

Step 3: Handling Result Array

If the result of your query is stored in an array, access the object values as follows:

resultArray[0]["user_id"] // where resultArray is the array of RowDataPacket objects

Note: You can check the constructor of an object using [object].constructor.name.
