Use xsodata to expose HANA tables as Odata services

This tutorial is designed for SAP HANA on premise and SAP HANA, express edition. It is not designed for SAP HANA Cloud. If you want to expose HANA Cloud tables, check Use CAP to expose HANA Cloud tables as Odata services.

Expose data residing in SAP HANA via Odata services

Prerequisites

• SAP HANA, or SAP HANA, Express edition
• Customers, orders, products tables created in your HDI container

Create a Node.js module in your project

Open the SAP Web IDE, right-click the project where you created a DB module and create a new Node.js Module.

Give a name to your Node,js Module. for example –  core_xsjs

Check “Enable XSJS Support”  By checking it, you enable the SAP XSJS libraries which allow you to use the programming model and APIs from the Extended Application Services, classic model.

A node.js module called core_xsjs gets created in your project

The mta.yaml file has been extended to add the core_xsjs module.
This XSJS module will also need data from the database module and the HDI container behind it. Add those dependencies to the node module Requires section.Additionally add the UAA service for authentication if you created it. Then save and close the mta.yaml.

This step is essential : if dependencies are not declared in the mta.yaml file, your Node.js module will not be able to access the HDI container.

Create an Odata service with xsodata

Input xsodata/customers/xsodata
This will create a new folder xsodata, and a file customers.xsodata within it.

Within customers.xsodata, paste the following code :

service {
	"order-entry.db::customers"
	  as "customers";
}

This code creates an Odata service v2.0 exposing the content of the table order-entry.db::customers.
You could do the same with views or virtual tables

Run and test your service

Right-click your Node.js module core_xsjs and Run it as a Node.js Application.

This will build and run the Node.js application. Click on the URL of the node.js service, and add this path at the end : /xsodata/customers.xsodata/customers?$format=json

This will access your Odata service.
