Hey Community,

We're pleased to invite everyone to the upcoming kick-off Webinar for InterSystems "Bringing Ideas to Reality" Contest!

During the webinar, our speakers will explore the Community Opportunity Ideas from the InterSystems Ideas Portal, which are the topics of this programming contest. They will show how to develop, build, and deploy applications using the InterSystems IRIS data platform.

Date & Time: Monday, November 17 – 10:30 am EST | 4:30 pm CET

Can someone give me an explanation of how Local.PD.Linkage.Definition.Individual works? This was setup by another company as part of our implementation.

Below is my configuration..

We are getting a lot of matches on Given Name, but then the Family Name does not match at all, so I am wondering if these need to be adjusted. I just don't understand if they need to be positive or negative.

Hi community

I have a persistent data class where there are some properties that contain underscores in their names, for example:

Hi Community,

Please welcome @Henry Pereira as our new Moderator in the Developer Community Team! 🎉

As an active member, Henry has consistently shared valuable insights, supported fellow developers, and driven meaningful discussions across the Community. His deep expertise and collaborative spirit make him a perfect fit to help guide and grow our Developer Community.

Let's greet Henry with a round of applause and look at his bio!

When using a EnsLib.RecordMap.Service.FileService business service, is there a way to tell which row number that is being read in? I want to read in a csv, but on the first record, trigger a truncate on the External SQL Table that it is being written to through JDBC.

Thanks

Scott

Hi,

I'd like to report a really strange behavior of the Intersystems Lite Terminal after executing a simple ObjectScript instruction.

From the Intersystems Lite terminal, execute the following instructions:

- Set uniqueId = "12345678_1"
- Set uniqueId = $p(uniqueId,"_",1)_"_"_($p(uniqueId,"_",*)+1)
After executing the second instruction, the terminal closes without any error.

Hi developers!

How do you debug implementation code in .impl classes of REST.API in InterSystems IRIS?

Especially if you don't have access to globals, so no things like:

Set ^AAA="here we are"

not possible in this case.

Suppose I have the following signature of the REST.API method called as POST and containing JSON. :

Is there any way of saving a representation of the results of a query created in the Message Viewer to a file - most obviously CSV.

We are reasonably adept at creating queries. We'd like to be able to send the output to a file, rather than resorting to cut'n'pasting from the message viewer window...

Is this possible? (on any version of Ensemble/Iris?)

Desired output to file something like:

Hi Community,

In this article, we will explore the concepts of Dynamic SQL and Embedded SQL within the context of InterSystems IRIS, provide practical examples, and examine their differences to help you understand how to leverage them in your applications.

InterSystems SQL provides a full set of standard relational features, including the ability to define table schema, execute queries, and define and execute stored procedures. You can execute InterSystems SQL interactively from the Management Portal or programmatically using a SQL shell interface. Embedded SQL enables you to embed SQL statements in your ObjectScript code, while Dynamic SQL enables you to execute dynamic SQL statements from ObjectScript at runtime. While static SQL queries offer predictable performance, dynamic and embedded SQL offer flexibility and integration, respectively.

Introduction

The InterSystems IRIS Data Platform has long been known for its performance, interoperability, and flexibility across programming languages. For years, developers could use IRIS with Python, Java, JavaScript, and .NET — but Go (or Golang) developers were left waiting.

That wait is finally over.

The new go-irisnative driver brings GoLang support to InterSystems IRIS, implementing the standard database/sql API. This means Go developers can now use familiar database tooling, connection pooling, and query interfaces to build applications powered by IRIS.

Why GoLang Support Matters

GoLang is a language designed for simplicity, concurrency, and performance — ideal for cloud-native and microservices-based architectures. It powers some of the world’s most scalable systems, including Kubernetes, Docker, and Terraform.

Bringing IRIS into the Go ecosystem enables:

• Lightweight, high-performance services using IRIS as the backend.
• Native concurrency for parallel query execution or background processing.
• Seamless integration with containerized and distributed systems.
• Idiomatic database access through Go’s database/sql interface.

This integration makes IRIS a perfect fit for modern, cloud-ready Go applications.

When I started my journey with InterSystems IRIS, especially in Interoperability, one of the initial and common questions I had was: how can I run something on an interval or schedule? In this topic, I want to share two simple classes that address this issue. I'm surprised that some similar classes are not located somewhere in EnsLib. Or maybe I didn't search well? Anyway, this topic is not meant to be complex work, just a couple of snippets for beginners.

Window functions in InterSystems IRIS let you perform powerful analytics — like running totals, rankings, and moving averages — directly in SQL.
They operate over a "window" of rows related to the current row, without collapsing results like GROUP BY.
This means you can write cleaner, faster, and more maintainable queries — no loops, no joins, no temp tables.

In this article let's understand the mechanics of window functions by addressing some common data analisys tasks.
