Query Veeva Data as a SQL Server Database in Node.js

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

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

Configure Veeva Connectivity for NodeJS

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

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

   You are ready to connect after specifying the following connection properties:

   • Url: The host you see in the URL after you login to your account. For example: https://my-veeva-domain.veevavault.com
   • User: The username you use to login to your account.
   • Password: The password you use to login to your account.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Veeva 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 Veeva data from Node.js.

Query Veeva from Node.js

The following example shows how to define a connection and execute queries to Veeva 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 Veeva (VeevaVault1)

Connect to Veeva 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: 'VeevaVault1'
	}
}

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

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