Query SAP Netweaver Gateway Data as a MySQL Database in Node.js

Execute MySQL queries against SAP Netweaver Gateway data from Node.js.

You can use the CData Cloud Hub to query SAP Netweaver Gateway data through a MySQL interface. Follow the procedure below to create a virtual database for SAP Netweaver Gateway in the Cloud Hub and start querying using Node.js.

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

Create a Virtual MySQL Database for SAP Netweaver Gateway Data

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "SAP Netweaver Gateway" from Available Data Sources.
  3. SAP Netweaver Gateway uses OAuth to authenticate. Click Test Database to authenticate with SAP Netweaver Gateway.
  4. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to SAP Netweaver Gateway data from any MySQL client.

Query SAP Netweaver Gateway from Node.js

The following example shows how to define a connection and execute queries to SAP Netweaver Gateway with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Cloud Hub (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on the Cloud Hub
  • Database name: The database you configured for SAP Netweaver Gateway (sapgatewaydb)

Connect to SAP Netweaver Gateway data and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'sapgatewaydb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM SalesOrderLineItems', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
