Get the Report →Query MongoDB Data as a SQL Server Database in Node.js
Execute SQL Server queries against MongoDB data from Node.js.
You can use CData Connect Cloud to query MongoDB data through a SQL Server interface. Follow the procedure below to create a virtual database for MongoDB in Connect Cloud and start querying using Node.js.
CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for MongoDB, allowing you to easily query live MongoDB 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 MongoDB, leveraging server-side processing to quickly return MongoDB data.
About MongoDB Data Integration
Accessing and integrating live data from MongoDB has never been easier with CData. Customers rely on CData connectivity to:
- Access data from MongoDB 2.6 and above, ensuring broad usability across various MongoDB versions.
- Easily manage unstructured data thanks to flexible NoSQL (learn more here: Leading-Edge Drivers for NoSQL Integration).
- Leverage feature advantages over other NoSQL drivers and realize functional benefits when working with MongoDB data (learn more here: A Feature Comparison of Drivers for NoSQL).
MongoDB's flexibility means that it can be used as a transactional, operational, or analytical database. That means CData customers use our solutions to integrate their business data with MongoDB or integrate their MongoDB data with their data warehouse (or both). Customers also leverage our live connectivity options to analyze and report on MongoDB directly from their preferred tools, like Power BI and Tableau.

Getting Started
Configure MongoDB Connectivity for NodeJS
Connectivity to MongoDB from NodeJS is made possible through CData Connect Cloud. To work with MongoDB data from NodeJS, we start by creating and configuring a MongoDB connection.
- Log into Connect Cloud, click Connections and click Add Connection
- Select "MongoDB" from the Add Connection panel
-
Enter the necessary authentication properties to connect to MongoDB.
Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.
- Click Create & Test
- Navigate to the Permissions tab in the Add MongoDB 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.
- Click on your username at the top right of the Connect Cloud app and click User Profile.
- On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
- Give your PAT a name and click Create.
- 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 MongoDB data from Node.js.
Query MongoDB from Node.js
The following example shows how to define a connection and execute queries to MongoDB with the SQL Server module. You will need the following information:
- server: tds.cdata.com
- port: 14333
- user: a Connect Cloud user (e.g. [email protected])
- password: the PAT for the above user
- database: The connection you configured for MongoDB (MongoDB1)
Connect to MongoDB data and start executing queries with the code below:
var sql = require('mssql') var config = { server: 'tds.cdata.com', port: 14333, user: '[email protected]', //update me password: 'CONNECT_USER_PAT', //update me options: { encrypt: true, database: 'MongoDB1' } } sql.connect(config, err => { if(err){ throw err ; } new sql.Request().query('SELECT * FROM restaurants', (err, result) => { console.dir(result) }) }); sql.on('error', err => { console.log("SQL Error: " ,err); })
