SAP HANA XS Advanced MuleSoft Connector



Create a simple Mule Application that uses HTTP and SQL with the CData Mule Connector for SAP HANA XS Advanced to create a JSON endpoint for SAP HANA XS Advanced data.

The CData Mule Connector for SAP HANA XS Advanced connects SAP HANA XS Advanced data to Mule applications enabling read functionality with familiar SQL queries. The Connector allows users to easily create Mule Applications to backup, transform, report, and analyze SAP HANA XS Advanced data.

This article demonstrates how to use the CData Mule Connector for SAP HANA XS Advanced inside of a Mule project to create a Web interface for SAP HANA XS Advanced data. The application created allows you to request SAP HANA XS Advanced data using an HTTP request and have the results returned as JSON. The exact same procedure outlined below can be used with any CData Mule Connector to create a Web interface for the 200+ available data sources.

  1. Create a new Mule Project in Anypoint Studio.
  2. Add an HTTP Connector to the Message Flow.
  3. Configure the address for the HTTP Connector.
  4. Add a CData SAP HANA XS Advanced Connector to the same flow, after the HTTP Connector.
  5. Create a new Connection (or edit an existing one) and configure the properties to connect to SAP HANA XS Advanced (see below). Once the connection is configured, click Test Connection to ensure the connectivity to SAP HANA XS Advanced.

    SAP HANA XSA uses the OAuth authentication standard. Before connecting, it is necessary to establish an SAP HANA XSA OData Service. See the OAuth section in the Help documentation for a guide.

  6. Configure the CData SAP HANA XS Advanced Connector.
    1. Set the Operation to 'Select with Streaming'.
    2. Set the Query type to Dynamic.
    3. Set the SQL query to SELECT * FROM #[message.inboundProperties.'http.query.params'.get('table')] to parse the URL parameter table and use it as the target of the SELECT query. You can customize the query further by referencing other potential URL parameters.
  7. Add a Transform Message Component to the flow.
    1. Map the Payload from the input to the Map in the output.
    2. Set the Output script to the following to convert the payload to JSON:
      %dw 1.0
      %output application/json
      ---
      payload
              
  8. To view your SAP HANA XS Advanced data, navigate to the address you configured for the HTTP Connector (localhost:8081 by default) and pass a table name as the table URL parameter: http://localhost:8081?table=
    The data is available as JSON in your Web browser and any other tools capable of consuming JSON endpoints.

At this point, you have a simple Web interface for working with SAP HANA XS Advanced data (as JSON data) in custom apps and a wide variety of BI, reporting, and ETL tools.
