Question Dmitrii Baranov · Dec 14, 2025

Hi,

I need a simple function for formatting a string, like in Python or C#. That's easy:

Class Very.Very.Long.Class.Name
{
ClassMethod Format(fmt As %String, args...) As %String [ Language = python ]
{
return fmt.format(*args)
}
}

To simplify calls, I want to wrap the function into a macro:

ROUTINE StringUtil [Type=INC]

#define FMT(%fmt,%a0)                                           ##class(Very.Very.Long.Class.Name).Format(%fmt,%a0)
/// #define FMT(%fmt,%a0,%a1)                              ##class(Very.Very.Long.Class.Name).Format(%fmt,%a0,%a1)
/// #define FMT(%fmt,%a0,%a1,%a2)

Question Dmitrij Vladimirov · Nov 26, 2025

I use $SELECT() in Architect to aggregate various data conditions into a single dimension.

I have a data table like this: id, user, userData1, userData2...

Where each user action is the %Integer ID of that action from some source.Then in expression field i use: $SELECT(userAction1:"This user action", userAction2:"That user action"...) and so on, up to 14 conditions, excluding the default placeholder 1:"Other" (which is always empty because there is a condition with 100% chance).The logic is simple: if userAction1 is not null then SELECT return "This user action" and so on.

Hi everyone. Long time no see. Again, I would like to share what I am studying recently Create Foreign Tables Using SQL via JDBC.

Since I am learning about the IRIS BI at the same time, so I started with this Sample-BI docker environment

https://github.com/intersystems/Samples-BI

After starting the environment, login to the management portal http://localhost:52773/csp/sys/UtilHome.csp  with the user Superuser.

Switch the namespace to IRISAPP.

😀 We will find out that all the sample data are stored in this namespace IRISAPP. Let's find a simple table for testing the Foreign Table feature 🤣

Introduction

As AI-driven automation becomes an essential part of modern information systems, integrating AI capabilities into existing platforms should be seamless and efficient. The IRIS Agent project showcases how generative AI can work effortlessly with InterSystems IRIS, leveraging its powerful interoperability framework—without the need to learn Python or build separate AI workflows from scratch.
This project explores how ChatGPT and Anthropic Claude, two of the most advanced AI models, can interact with IRIS using Custom GPTs and the Model Context Protocol (MCP).

If one of your packages on OEX receives a review, you get notified by OEX only of YOUR own package.   
The rating reflects the experience of the reviewer with the status found at the time of review.   
It is kind of a snapshot and might have changed meanwhile.   
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on GitHub when I found a problem I could fix.    
Some were accepted and merged, and some were just ignored.     
So if you made a major change and expect a changed review, just let me know.

Question Timothy Leavitt · Aug 26, 2025

What are best practices for JSON transformation in IRIS interoperability? This is for a non-healthcare use case, so any tools we happen to have around FHIR might not be available. The motivating use case is trimming down a verbose and needlessly complex REST API response to feed to an LLM - trying to reduce token usage and maybe get better results from less noisy data.

Specifically, I'm imagining matching based on JSONPath expressions and simplifying structures based on the inferred type of elements rather than a full schema.

The previous article introduced IrisOASTestGen, a tool designed to generate REST API test code for InterSystems IRIS based on OpenAPI 2.0 specifications. It demonstrated how to scaffold test cases using the default templates bundled with OpenAPI Generator.

This follow-up focuses on the next natural step: customizing the generated test code. By extending the code generation logic with Mustache templates, it becomes possible to express richer semantics, implement CRUD-aware tests, and create more meaningful test suites.

The example in this article will modify IrisOASTestGen to generate tests for

Modern SQL engines are enormously complex pieces of software. Even when they appear stable and mature, subtle bugs can hide in their optimizers, type systems, predicate evaluation, or execution layers. These bugs rarely announce themselves loudly. Instead, they quietly produce incorrect results, behave inconsistently, or fail abruptly under specific combinations of SQL constructs.

This is precisely why tools like SQLancer exist. SQLancer automatically generates SQL queries and uses logical “oracles” to detect when a database behaves incorrectly. It has revealed hundreds of real bugs in widely used systems such as MySQL, PostgreSQL, SQLite, and DuckDB.

With this in mind, I attempted to bring SQLancer to InterSystems IRIS, starting with the NOREC oracle — a powerful method for detecting optimizer correctness issues. The journey, however, uncovered not just potential SQL correctness problems, but also a surprising number of driver-level and server-level failures that prevented SQLancer from running at full strength.

This article summarizes why SQLancer is important, how the NOREC oracle works, and what unexpected findings appeared while testing IRIS.

Question Dmitrii Baranov · Dec 9, 2025

I need to connect IRIS to a third-party FHIR server which in turn is connected to Keycloak.

For machine-to-machine communications, client credentials grants should be used. I don't know why exactly but the FHIR server requires access tokens to contain the "openid" scope, otherwise it returns 401 (unauthorized).

If the access token returned by Keycloak contains that scope, IRIS complains about ""ERROR #8859: Unsupported response to access token request: OpenID Connect is not supported for password and client credentials grant type". The error is produced by the OAuth2.Response class, line 393:
