We have a query that looks something like:

select a, b, c, d, e, f

from tbla inner join tblb on tbla.....

This query runs in the expected 200-400 ms range.

If we run the same query but reduce the select to just:

select a

from tbla inner join tblb on tbla.....

then the query runs for 30 minutes or more.

The rest of the query is identical. Is there a logical explanation for how this can happen?

Thanks.

Q&A Chatbot with IRIS and langchain

TL;DR

This article introduces using the langchain framework supported by IRIS for implementing a Q&A chatbot, focusing on Retrieval Augmented Generation (RAG). It explores how IRIS Vector Search within langchain-iris facilitates storage, retrieval, and semantic search of data, enabling precise and up-to-date responses to user queries. Through seamless integration and processes like indexing and retrieval/generation, RAG applications powered by IRIS enable the capabilities of GenAI systems for InterSystems developers.

Context

I have created a Business Operation (BO) named "Sender" that sends HTTP messages to an endpoint (for testing, I'm using Postman's Mock Servers).

Goal: I want to set up an automatic timeout mechanism so that if I don't receive a response from the server within 18 seconds, an alert is generated and the message is resent. This process should be repeated every 18 seconds, for a maximum of 90 seconds. If no response is received within 90 seconds, I would like to generate an error message. On the other hand, if a response is received, I want to stop the resending process and complete the operation by indicating successful reception.

I need to create a routing rule where I've got to check for the value of "-" in field 5 of a repeating RQD segment, if the "-" is found in any of the RQD-5 I want to send it to a transform, if the rule doesn't find a "-" in any of the RQD-5 I want to send it to another transform.

Unfortunately we are running an older version of Ensemble and the foreach function is not available.

The other thing to add is the transforms are writing the output to a flat file so my business process is using the EnsLib.MsgRouter.RoutingEngine class.

I recently started to study interoperability and I found the official documentation very helpful in understanding how it works, though I still had some trouble implementing it myself. With the help I got from my coworkers, I managed to create a Demo of a system and learn through practice. Because of that, I decided to write this to help others with "getting their hands dirty" and share the help I got.

First of all thanks for your help and time

We would need to find inside PID:3 which one meets the following condition:

PID 3.4.1 = "CAC" and PID 3.5 = "JHN"

We have been investigating how could we do it

We have achieved to get single fields in a call request as follows:

request.GetValueAt("ORCgrp(1).ORC:OrderingProvider(1).IDNumber")

##class(Ens.Util.Time).ConvertDateTime(request.GetValueAt("PID:DateTimeofBirth"),"%Y%m%d","%Y-%m-%d")

Hello all,
I am creating a REST API with a spec-first approach. However, I am using the try-catch method to handle any exception if any occurs. But whenever any error related to syntax or something occurs, we get internal server error

{

"errors": [

{

"code": 6220,

"domain": "%ObjectErrors",

"error": "ERROR #6220: Internal Server Error",

"id": "InternalError"

}

],

"summary": "ERROR #6220: Internal Server Error"

}
