Query Microsoft CDS Data as a MySQL Database in Node.js

Execute MySQL queries against Microsoft CDS data from Node.js.

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

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Microsoft CDS, allowing you to easily query live Microsoft CDS data 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 Microsoft CDS, leveraging server-side processing to quickly return Microsoft CDS data.

Create a Virtual MySQL Database for Microsoft CDS Data

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 "Microsoft CDS" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Microsoft CDS.

    You can connect without setting any connection properties for your user credentials. Below are the minimum connection properties required to connect.

    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
    • OrganizationUrl: Set this to the organization URL you are connecting to, such as https://myorganization.crm.dynamics.com.
    • Tenant (optional): Set this if you wish to authenticate to a different tenant than your default. This is required to work with an organization not on your default Tenant.

    When you connect the Common Data Service OAuth endpoint opens in your default browser. Log in and grant permissions. The OAuth process completes automatically.

  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 Microsoft CDS data from any MySQL client.

Query Microsoft CDS from Node.js

The following example shows how to define a connection and execute queries to Microsoft CDS 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 Microsoft CDS (microsoftcdsdb)

Connect to Microsoft CDS data 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 : 'microsoftcdsdb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM Accounts', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
