Query Salesforce Data as a MySQL Database in Node.js

Execute MySQL queries against Salesforce data from Node.js.

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

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

Create a Virtual MySQL Database for Salesforce 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 "Salesforce" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Salesforce.

    There are several authentication methods available for connecting to Salesforce: Login, OAuth, and SSO. The Login method requires you to have the username, password, and security token of the user.

    If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication.

    SSO (single sign-on) can be used by setting the SSOProperties, SSOLoginUrl, and TokenUrl connection properties, which allow you to authenticate to an identity provider. See the "Getting Started" chapter in the help documentation for more information.

  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 Salesforce data from any MySQL client.

Query Salesforce from Node.js

The following example shows how to define a connection and execute queries to Salesforce 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 Salesforce (salesforcedb)

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

connection.end();
