I had a need for a Filter, but did not want to recreate the wheel by creating another Data Lookup Table, so instead I created a Linked Table that points to a MS SQL Table outside of IRIS.

Once I had the Linked Table, I created a Class Method Function that would query the Linked Table and return a 1 if a result came back.

ClassMethod CheckPDMProviderType(pInput As%String) As%Boolean
{
    set ExtDisplay = ""
 		&sql(SELECT SecurityGroup_k INTO :ExtDisplay
        FROM osuwmc_CPD_SQL.Ref_SecurityGroup WHERE PDMExtDisplay = 1AND SecurityGroup_k = :pInput)
    if ExtDisplay = "" {
        q

InterSystems FAQ rubric

There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.

Temporary Globals and the IRISTEMP Database

By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.

However, the contents of this database will be cleared when IRIS is restarted, so if you want to keep it permanently, you will need to copy it to a

Hi folks!

It is very easy to import CSV data into IRIS. But what if we want to preserve the original IDs in CSV?

Recently I came across with the situation when I needed to import two csv's into IRIS which were linked by one column referencing  to another csv's col: a typical Foreign Key and Primary Key situation, where csv1 contains this column as Primary Key, and csv2 as Foreign key with id's related to csv1.

The image is generated by ChatGPT so don't blame it - it tried its best to generate countries as primary keys with countries.csv-cities.csv relationship :)

I have a need to create a specific Search Table outside of the EnsLib.HL7.SearchTable specifically for HL7 MFN messages in HealthShare Provider Directory.

Our Code is created in a different namespace then the main HSPD namespace and is mapped within the HSPD namespace mapping. 

I created a copy of EnsLib.HL7.SearchTable, named OSU.HL7.SearchTable what all needs mapped to make this new search table available in HSPD namespace?

If I go to Global within the Custom Code Namespace, I cannot see my new Search Table being created.

What am I missing to make sure that the OSU.HL7.SearchTable available

Developing with InterSystems Objects and SQL – In PersonSeptember 15-19, 2025

• This 5-day course teaches programmers how to use the tools and techniques within the InterSystems® development environment.
• Students develop a database application using object-oriented design, building different types of IRIS classes.
  
  • They learn how to store and retrieve data using Objects or SQL, and decide which approach is best for different use cases.
  • They write code using ObjectScript, Python, and SQL, with most exercises offering the choice between ObjectScript and Python, and some exercises

I’m pleased to announce the release of tree-sitter-objectscript, a new open-source tree-sitter grammar that brings first-class ObjectScript support to modern editors. If you caught the preview at READY ’25, you’ll be glad to know it’s now up on Github:

What Does It Provide?

• Fast & Precise Parsing: A powerful grammar for ObjectScript, enabling real-time syntax parsing, smart highlighting, and structural editing in modern code editors.
• Polyglot-Awareness: ObjectScript .cls files often embed SQL, HTML, Python, JavaScript, JSON, CSS, XML, and

Hello,

I have a main dispatcher (that extends%CSP.REST) that contains:
<Routes>
   <Map Prefix="/v([0-9]{1,2})/news"    Forward="API.Dispatch.news"/>
</Routes>

And I have the sub-dispatcher that contains:
<Routes>
   <Route Url="/:id"                        Method="GET"  Call="NewsGetItem"/>
</Routes>
If I try to access this route:
https://mydomain.com/mobile/api/v4/news/123
It doesn't work (404).
 

But strangely enough, it works (200):

In this case, a robot is nothing like Gort from the movie “The Day the Earth Stood Still” or any other humanoid robot from science fiction. Nor is this Robot the one-armed automated welder from a real-world automotive assembly line. This Robot is a program that controls another program. You might want this for automated testing or to capture application logic from an application for which you don’t have the source, and the application’s author lacked the kindness or foresight to provide an API for its capabilities.

In this article, I will present two ways to implement a robot with InterSystems

⏯️  Closing the Scientific Knowledge Gap with AI

For venture capitalists (VCs), evaluating research can be challenging. While researchers typically possess years of training and deep expertise in their field, the VCs tasked with assessing their work often lack domain-specific knowledge. This can lead to incomplete understanding of scientific data and an inability to direct organizational initiatives. To solve this problem, we have designed a solution that empowers VCs with AI-driven due diligence: ResearchExplorer. ResearchExplorer is powered by InterSystems IRIS and GPT-4o to help analyze private biomedical research alongside public sources like PubMed using Retrieval-Augmented Generation (RAG). Users submit natural language queries, and the system returns structured insights, head-to-head research comparisons, and AI-generated summaries. This allows users to bridge expertise gaps while securely protecting proprietary data.

Given:
class Foo.Bar extends Ens.BusinessOperation
{
Parameter SETTINGS = "Whatever:Basic";
}

class Foo.Baz extends Foo.Bar
I want to somehow drop "Whatever" as a setting from Foo.Baz. How can I do this?

I would like to know which are the best practices of using Streams in Interoperability messages.

I have always use %Stream.GlobalCharacter properties to hold a JSON, or a base64 document, when creating messages. This is fine and I can see the content in Visual Trace without doing anything, so I can check what is happening and resolve issues if I have, or reprocess messages if something went wrong, because I have the content.

But I think this is not the best way of using Streams.

While starting with Intersystems IRIS or Cache, developers often encounter three core concepts: Dynamic Objects, Globals & Relational Table. Each has its role in building scalable and maintainable solutions. In this article, we'll walk through practical code examples, highlight best practices, and show how these concepts tie together. 

1. Working with Dynamic Objects:

Dynamic objects (%DynamicObject and %DynamicArray) allow developers to manipulate JSON-like structures directly in Objectscript. They are especially useful for modern applications that need to parse, transform or generate JSON.

Hi folks!

Consider I have a class "X.Y.Z"

What is the SQL table name for it? How can I obtain it via ObjectScript? 

A quick search doesn't show any methods and properties. Documentation is a bit "wrong" here saying that the SQL table name is the same. It will be at least 'x_y.z'.

Any help is very appreciated!)

Recently, I replaced my old laptop with a new one and had to migrate all my data. I was looking for a guide but couldn’t find anything that explained in detail how to migrate server connections from InterSystems Studio and Visual Studio Code from one PC to another. Simply reinstalling the tools is not enough, and migrating all the connections manually seemed like a waste of time. In the end, I managed to solve the problem, and this article explains how.

InterSystems Studio

Exporting Server Connections

Migrating Studio connections was the most challenging part.

SQLTools is a Visual Studio Code (VS Code) Extension with over 3.5 million downloads that provides connections to many of the most used databases, including InterSystems IRIS, using drivers.
For developers new to VS Code, or those already familiar with it but are looking to streamline their connections to InterSystems IRIS, this tutorial will take you through installing the SQLTools extensions and the InterSystems IRIS drive. It then guides you on how to establish a connection to your instance of InterSystems IRIS and run a query.
You will need: VS Code installed on your system and access to

Or can I change namespaces within one connection object?

Running "docker exec -it iris iris terminal IRIS" automatically logs you in as irisowner in the terminal session, but how do you log in as a different user?

This article describes a significant enhancement of how InterSystems IRIS deals with table statistics, a crucial element for IRIS SQL processing, in the 2025.2 release. We'll start with a brief refresher on what table statistics are, how they are used, and why we needed this enhancement. Then, we'll dive into the details of the new infrastructure for collecting and saving table statistics, after which we'll zoom in onto what the change means in practice for your applications. We'll end with a few additional notes on patterns enabled by the new model, and look forward to the follow-on phases of this initial delivery.

This article outlines the process of utilizing the renowned Jaeger solution for tracing InterSystems IRIS applications. Jaeger is an open-source product for tracking and identifying issues, especially in distributed and microservices environments. This tracing backend that emerged at Uber in 2015 was inspired by Google's Dapper and Twitter's OpenZipkin. It later joined the Cloud Native Computing Foundation (CNCF) as an incubating project in 2017, achieving graduated status in 2019. This guide will demonstrate how to operate the containerized Jaeger solution integrated with IRIS.

The August Article Bounty on the Global Masters article caught my attention, and one of the proposed topics sounded quite interesting in regard to its future use in my teaching. So, here's what I'd like to tell my students about tables in IRIS and how they correlate with the object model. 

First of all, InterSystems IRIS boasts a unified data model. This means that when you work with data, you are not locked into a single paradigm. The same data can be accessed and manipulated as a traditional SQL table, as a native object, or even as a multidimensional array (a global). It means that when you create an SQL table, IRIS automatically creates a corresponding object class. When you define an object class, IRIS automatically makes it available as an SQL table. The data itself is stored only once in IRIS's efficient multidimensional storage engine. The SQL engine and the object engine are simply different "lenses" to view and work with the same data.

First, let's look at the correlation between the relational model and the object model:

It's not always a 1:1 correlation, as you may have several tables represent one class, for example. But it's a general rule of thumb. 

Over the years, I’ve noticed that certain SQL questions come up repeatedly on the InterSystems Developer Community, especially about using the LIKE predicate in different contexts. Common variations include:

• using special characters in queries
• using variables in queries

and many more derivatives. So, I decided to write an article that focuses on how LIKE works in InterSystems IRIS SQL, especially when used with variables in Embedded SQL, Dynamic SQL, and Class Queries, while touching on pattern escaping and special character searches.

First of all, I'd like to mention that InterSystems IRIS SQL offers most of the capabilities available in other relational DBMS that implement a later version of the SQL standard. But at the same time, it's important to mention that apart from relational access, in IRIS you can also use other models to get the same data, for example, object or document models. 

On this note, let's look at the LIKE predicate and how this tool is used in SQL for pattern matching. 

In recent versions of IRIS, a powerful new data loading command has been introduced to SQL: LOAD DATA. This feature has been highly optimized to import data into IRIS extremely fast, allowing hundreds of gigabytes of data to be inserted in seconds instead of hours or days. 

This is a very exciting improvement. However, a big problem in the data loading experience still exists. Namely, the time and hassle it takes to:

1. Define the schema for the table in which you want to load data.
2. Figure out the syntax for the LOAD DATA command.

I've developed a user interface that invisibly handles the

Dynamic Entities (objects and arrays) in IRIS are incredibly useful in situations where you are having to transform JSON data into an Object Model for storage to the database, such as in REST API endpoints hosted within IRIS. This is because these dynamic objects and arrays can easily serve as a point of conversion from one data structure to the other.

Dynamic Objects

Dynamic Objects are very similar to the standard ObjectScript object model you get when you create a new instance of a class object, but with some key differences:

• Dynamic objects have no real type, other than being a
