Query PCA Sales Data as a SQL Server Database in Node.js

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

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

Configure PCA Sales Connectivity for NodeJS

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

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

   In order to authenticate using the OAuth, specify the following:

   • AuthScheme: Set to OAuth.

   In order to authenticate using the OAuth Password, specify the following:

   • AuthScheme: Set to OAuthPassword.
   • User: Enter the PCA Sales username.
   • Password: Enter the PCA Sales password.
   • ServiceId: Enter the Service ID used to connect tot he PCA API server.
   • ServicePassword: Enter the Service Password for the above Service ID.

   For both authentication methods, specify the following:

   • Data Center: Enter the name for the PCA API Server.
   • Default Data Area: Enter the data area to which you want to connect.
   • Product Code: Enter "Kon20" or "Acc20."

   For more information, refer to the Help documentation.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add PCA Sales 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 PCA Sales data from Node.js.

Query PCA Sales from Node.js

The following example shows how to define a connection and execute queries to PCA Sales 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 PCA Sales (PCASales1)

Connect to PCA Sales 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: 'PCASales1'
	}
}

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

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