Query Oracle SCM Data as a SQL Server Database in Node.js

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

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

Configure Oracle SCM Connectivity for NodeJS

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

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

   The following connection properties are required to connect to Oracle SCM data.

   • Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
   • User: The username of your Oracle Cloud service account.
   • Password: The password of your Oracle Cloud service account.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Oracle SCM 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 Oracle SCM data from Node.js.

Query Oracle SCM from Node.js

The following example shows how to define a connection and execute queries to Oracle SCM 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 Oracle SCM (OracleSCM1)

Connect to Oracle SCM 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: 'OracleSCM1'
	}
}

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

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