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

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

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

Configure Suadeo Connectivity for NodeJS

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

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "Suadeo" from the Add Connection panel

3. Enter the necessary authentication properties to connect to Suadeo.

   The driver uses the OAuth 2.0 Resource Owner Password Credentials (ROPC) grant to authenticate to Suadeo. Authentication occurs directly using your credentials; there is no browser-based authorization flow or refresh token.

   Set the following connection properties:

   • URL: The base URL of your Suadeo instance.
   • User: Your Suadeo username.
   • Password: Your Suadeo password.
   • AuthenticationName: The name identifier for the authentication configuration in your Suadeo instance. Different authentication names can be configured for different environments or use cases.

   When you connect, the driver sends your credentials to the Suadeo OAuth token endpoint, receives an access token, and uses it for all subsequent requests. A new access token is obtained automatically when needed during the session.

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

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the 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 and a PAT generated, you are ready to connect to Suadeo data from Node.js.

Query Suadeo from Node.js

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

• server: tds.cdata.com
• port: 14333
• user: a Connect AI user (e.g. [email protected])
• password: the PAT for the above user
• database: The connection you configured for Suadeo (Suadeo1)

Connect to Suadeo 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: 'Suadeo1'
	}
}

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

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