Query Oracle Eloqua Data as a SQL Server Database in Node.js

You can use CData Connect Cloud to query Oracle Eloqua data through a SQL Server interface. Follow the procedure below to create a virtual database for Oracle Eloqua in Connect Cloud and start querying using Node.js.

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

Configure Oracle Eloqua Connectivity for NodeJS

Connectivity to Oracle Eloqua from NodeJS is made possible through CData Connect Cloud. To work with Oracle Eloqua data from NodeJS, we start by creating and configuring a Oracle Eloqua connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Oracle Eloqua" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Oracle Eloqua.

   There are two authentication methods available for connecting to Oracle Eloqua: Login and OAuth. The Login method requires you to have the Company, User, and Password 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. OAuth is better suited for allowing other users to access their own data. Using login credentials is better suited for accessing your own data.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Oracle Eloqua Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Oracle Eloqua data from Node.js.

Query Oracle Eloqua from Node.js

The following example shows how to define a connection and execute queries to Oracle Eloqua with the SQL Server module. You will need the following information:

• server: tds.cdata.com
• port: 14333
• user: a Connect Cloud user (e.g. user@mydomain.com)
• password: the PAT for the above user
• database: The connection you configured for Oracle Eloqua (OracleEloqua1)

Connect to Oracle Eloqua data and start executing queries with the code below:

var sql = require('mssql')
var config = {
	server: 'tds.cdata.com',
	port: 14333, 
	user: 'user@mydomain.com', //update me
	password: 'CONNECT_USER_PAT', //update me	
	options: {
		encrypt: true,
		database: 'OracleEloqua1'
	}
}

sql.connect(config, err => { 
    if(err){
        throw err ;
    }
    new sql.Request().query('SELECT * FROM Campaign', (err, result) => {
        console.dir(result)
    })
        
});

sql.on('error', err => {
    console.log("SQL Error: " ,err);
})
