Query ServiceNow Data as a MySQL Database in Node.js

Execute MySQL queries against ServiceNow data from Node.js.

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

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

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

    ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.

    See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

  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 ServiceNow data from any MySQL client.

Query ServiceNow from Node.js

The following example shows how to define a connection and execute queries to ServiceNow 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 ServiceNow (servicenowdb)

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

connection.end();
