Query PowerShell Scripts as a MySQL Database in Node.js

Execute MySQL queries against PowerShell scripts from Node.js.

You can use the CData Cloud Hub to query PowerShell scripts through a MySQL interface. Follow the procedure below to create a virtual database for PowerShell in the Cloud Hub and start querying using Node.js.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for PowerShell, allowing you to easily query live PowerShell scripts in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to PowerShell, leveraging server-side processing to quickly return PowerShell scripts.

Create a Virtual MySQL Database for PowerShell Scripts

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "PowerShell" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to PowerShell.

    The ScriptLocation, under the Data section, must be set to a valid script location.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to PowerShell scripts from any MySQL client.

Query PowerShell from Node.js

The following example shows how to define a connection and execute queries to PowerShell with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Cloud Hub (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on the Cloud Hub
  • Database name: The database you configured for PowerShell (powershelldb)

Connect to PowerShell scripts and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'powershelldb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Process', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
