Next time, try checking as well the output in the browser's developer console, as it might have some more details about the error.

Re: HANA SQL QUERY TO FETCH NESTED JSON OBJECTS

2025-02-06T22:50:51.677000+01:00

It's not that straightforward, but can you try

WITH ColB_Aggregated AS (
    SELECT 
        COLA,
        '[' || STRING_AGG('{"COLB": "' || COLB || '"}', ', ') || ']' AS COLB_JSON
    FROM YourTable
    GROUP BY COLA
)
SELECT 
    '[' || STRING_AGG('{ "COLA": "' || COLA || '", "COLB": ' || COLB_JSON || ' }', ', ') || ']' AS FINAL_JSON
FROM ColB_Aggregated;

Hi, Sebastien.

The correct link to the help page -- visible to customers -- should be: https://help.sap.com/docs/JOULE/6189c8655c484916bb8eb767126a653a/ade9ce3c7c5546988cccea15ec35d373.html?version=CLOUD&locale=en-US

Re: SAP Hana Express licence with more than 32GB

2025-02-11T12:11:13.669000+01:00

@akullerThe upgrade options of SAP HANA, express edition, were discontinued a few years ago due to the very low interest in such upgrades in the ecosystem. Regards. --Witalij

Re: Datasphere Internal error: SQL View - Resource governor for 'cursors' exceeded

2025-02-11T12:31:56.120000+01:00

I am not familiar with this error, but from what I can read, it is using a connection to SAP HANA Cloud, DL RE (based on SAP IQ database technology) as a component of Datasphere. It should be related to that setting: https://help.sap.com/docs/SAP_HANA_DATA_LAKE/19b3964099384f178ad08f2d348232a9/a63e2b9784f21015983992c1d7a76694.html?locale=en-US&state=PRODUCTION

I do not know if you can manipulate a number of these temporary tables to reduce the number of cursors they open simultaneously. If not, then I would suggest opening a service case to SAP Support.

Regards.

Re: Request for SAP Code Jam Event in Lucerne

Hi @MarcoSchmid . I will be working with you on delivering this SAP CodeJam. I will contact you via an email.

🇵🇱 Build AI services using the SAP Cloud Application Programming Model and SAP generative AI

2025-03-11T18:15:07.807000+01:00

This SAP CodeJam event focuses on building AI services using the SAP Cloud Application Programming Model, SAP AI Core, and SAP Generative AI Hub.

During the event, you will learn about the fundamentals of the genAI, SAP AI Core, and SAP AI Launchpad. You will also learn how to use the SAP Cloud Application Programming Model to expose AI capabilities through your own OData service. While working through the exercises, you will become comfortable creating CDS-based service definitions and integrating them with the SAP Business Technology Platform (BTP) and SAP AI Core Foundation Models.

This is an in-person event (not virtual) scheduled for Thursday, April 3rd, 2025, in Kraków, Poland 🇵🇱 from 10:00 to 16:00. The workshop will be held at the EPAM office and conducted in English.

Prerequisites: Bring your own laptop with a Chromium-based web browser, such as Chrome, Edge, or Vivaldi. Basic knowledge of JavaScript is beneficial, as you will be using the SAP Cloud SDK for AI with the JavaScript variant.

Please note that seating is limited to 25 attendees. Register for this Community Event using the RSVP functionality on this page.

The instructor will be Developer Advocate @Vitaliy-R.

For more information about SAP CodeJam events, to ask questions, and to chat with fellow attendees, visit the SAP CodeJam group.

I am not proficient with JavaScript. I looked into https://github.com/SAP/ai-sdk-js/blob/1f7b857b49da02604f6b9b2539956de881c6c5cf/sample-code/src/ai-api/scenario-api.ts#L27 to see if that's the API you are looking for: https://api.sap.com/api/AI_CORE_API/path/scenario.query_models?

SAP CodeJam HANA ML in India 2025-03 Recap

2025-03-14T16:41:12.059000+01:00

At the beginning of March 2025, as part of the ML/AI Tour my fellow dev advocate @noravonthenen and I did in India, we held five SAP CodeJam events in Kolkata, Pune, and Bengaluru.

Two of these events focused on getting started with Machine Learning using SAP HANA and Python.

Equally important were chances to catch up with some organizers and participants in informal post-work settings...

...or with our SAP colleagues.

I am glad Nora and I could help so many participants to go through the journey of improving their skills working with ML and AI!

Traditionally, I very much enjoyed SAP Stammtisch at the end of the last CodeJam of the Tour.

I always take the opportunity to experience at least a little bit of the city I am in, so you can see my photos:

Now, the next stop for me is in Kraków on April 3rd.

Would you like to host such an SAP CodeJam? Here are the details: https://community.sap.com/t5/technology-blogs-by-sap/quot-getting-started-with-machine-learning-usin...

Thank you for sharing!

I am also working on some exercises with FAQ embedding, search, and HANA-native chunking: https://github.com/Sygyzmundovych/hana-ai-ve-kg-codejam/tree/main/scripts/01-faq-search. However, it is still a work in progress.

Re: Invoke Generative AI Hub Models using @sap-ai-sdk/ai-...

2025-03-17T23:06:39.902000+01:00

I would need to check how it is done in JavaScript SDK, because in Python SDK it is enough to set the environment variables or a config file `~/.aicore/config.json` as per https://help.sap.com/doc/generative-ai-hub-sdk/CLOUD/en-US/_reference/README_sphynx.html#configuration.

Then the code automatically initiates a client with credentials from those configurations, without an explicit read from env variables or from that config file in your code.

But that's how it is done in Python, and I would need to check how it is done in JS.
