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

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

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

Configure ADP Connectivity for NodeJS

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

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

2. Select "ADP" from the Add Connection panel

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

   Connect to ADP by specifying the following properties:

   • OAuthClientId: The client Id of the custom OAuth application you obtained from ADP.
   • OAuthClientSecret: The custom OAuth application's client secret.
   • SSLClientCert: Set this to the certificate provided during registration.
   • SSLClientCertPassword: Set this to the password of the certificate.
   • UseUAT: The connector makes requests to the production environment by default. If using a developer account, set UseUAT = true.
   • RowScanDepth: The maximum number of rows to scan for the custom fields columns available in the table. The default value will be set to 100. Setting a high value may decrease performance.

   The connector uses OAuth to authenticate with ADP. OAuth requires the authenticating user to interact with ADP using the browser. OAuth access can be configured in ADP through ADP API Central. For more information, refer ADP's API Central Quick Start Guide and the OAuth section in CData's Help documentation.

   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add ADP 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 ADP data from Node.js.

Query ADP from Node.js

The following example shows how to define a connection and execute queries to ADP 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 ADP (ADP1)

Connect to ADP 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: 'ADP1'
	}
}

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

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