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

Is there a way to Remove specific all Addresses from a Provider.Individual.Address before reinserting the Addresses from an HL7 message in Provider Directory?

Most fields we can call %clearFields() however since Addresses come from multiple locations we need to isolate and treat Addresses from this HL7 source as a snapshot.

Thanks

⏯️ MyVitals: Connecting Wearable Health Data to EHRs with InterSystems

MyVitals is a Personal Health Device Hub that bridges the gap between wearable health devices and clinical workflows. In this demo, we show how healthcare organizations can enroll patients, collect real-time data from personal devices via mobile apps, and seamlessly integrate that information into EHR systems using FHIR, HL7, and InterSystems technology. Built on IRIS for Health and FHIR repositories, MyVitals turns disconnected wearable data into actionable clinical insights—securely, efficiently, and at scale.

Hi all,

I’m running into an issue with a %ZEN.Component.tablePane in a Zen page.

We have:

• A fully styled table with all columns defined
• A backend query (SearchMessages) that accepts multiple filter parameters
• A set of input fields at the top of the page for filtering (text, date, and checkboxes)

We’re trying to run the query from a button click using a client-side method (runSearch()) that collects the filter values, sets them as parameters, and calls executeQuery().

The problem is that the table does not update at all. Old rows remain, or sometimes nothing appears.

Hello
I want to get the property of a class, sorted by order in storage.

I know we can use
 

Set definition = ##class(%Dictionary.ClassDefinition).%OpenId(className)
        Set listProperty = definition.Properties
        For ii = 1:1:listProperty.Count(){
                    write listProperty.GetAt(ii).Name

But using GetAt sorts the results alphabetically.

Example :

Class Test.classExtends (%SerialObject, %XML.Adaptor, %JSON.Adaptor)
{

    Property tiers As%String;Property journal As%String;
}

listProperty.GetAt(1).Name = "journal" and listProperty.GetAt(2).Name = "tiers"

Hi everyone,

I am trying to create a treeMapChart in IRIS BI that will then be displayed on my DeepSeeWeb dashboard. In the IRIS BI User Portal, this is an example of what my treeMapChart looks like:

I know there is a huge amount of rectangles in this graphic - I care most about the common components (the largest boxes) but I still want all of the boxes to show. However, it projects to my DeepSeeWeb dashboard as the following:

Hello Community,

I’m working on an InterSystems IRIS production that needs to call an external API using OAuth client credentials (client_id and client_secret). For security reasons, I must pass these credentials via environment variables in my Docker container.

In the IRIS terminal, I can successfully retrieve these environment variables using $System.Util.GetEnviron("api-clientid") and $System.Util.GetEnviron("api-clientsecret"). However, inside my Business Operation class (OnMessage method), these environment variables return empty strings.

I verified that the variables are properly set in

⏯️ Data Transformation Adventures with InterSystems IRIS

Navigating interoperability and healthcare can be an exciting adventure. In this demo, we will show you how InterSystems IRIS can be the perfect tool to get data - wherever it may lie, in whatever format, into a format of your choice, including FHIR! Once that is done, analytics is a piece of cake with the FHIR SQL Builder and Deep See Web. Let the questing begin!

For example, you start debugging the AAA function, which calls the BBB function, then goes to the CCC^ABC function in a different routine and ends up while executing XXX^XYZ. No other routines or functions are visited in this example. What I would like is to get the record of AAA -> BBB -> CCC^ABC -> XXX^XYZ. No marking each function with recording code should be involved: too time consuming, too many functions in real code.

UPD: Iris has built in %SYS.Trace for this purpose but this class is apparently absent in Cache 2017. Did not find any substitutes yet.

This article is a continuation of the IRIS JSON project and features additional methods and insights.

This instance method is used to determine the JSON data type of the %DynamicObject or %DynamicArray.

It returns one of the following strings:

Been testing out the Production Validator toolkit, just to see what we can/not do with it. Seems really interesting and there seem to be some use cases for it that can really streamline some upgrades (or at least parts of upgrades) but I was running into so many hurdles with the documentation. I am curious if anyone else has used it.
Did you experience any issues getting it working? Any clarification that you would have liked in the documentation? any use cases that you worked through that made it particularly valuable? etc?
The hurdles I experienced included:

1. The documentation stated that the

When I open a class in VS Code and I want to save it I'm getting the following error : Non-JSON response to /api/atelier/v7/DEV/doc/API.Mollie.Execute.cls?ignoreConflict=0 request. Is the web server suppressing detailed errors?

Also I always get a popup when I open VS Code "The extension wants to sign in using InterSystems Server Credentials."

Hello Community,

I'm currently planning a system upgrade from Caché (2018.1.8.766) to InterSystems IRIS (2024.1). The environment consists of one database server and three application servers connected via ECP.

I’m considering two possible upgrade approaches:

1. Upgrade the application servers to IRIS first.
   Since IRIS is expected to be backward-compatible with Caché over ECP, the database server would remain on Caché temporarily.
2. Upgrade the database server first,
   followed by upgrading the application servers, as they don’t store data.

Could you please advise on the recommended approach,

Hi everyone,

I'm developing an Ensemble process that sends user data from a Business Process to a Business Operation using EnsLib.SQL.OutboundAdapter. The operation is supposed to call a stored procedure on a SQL Server.

The procedure works fine when executed directly from SQL Server Management Studio.

However, when I trigger it via Ensemble, I get the following error:

This great article sparked some recent private discussion, and I'd like to share some of my own thoughts from it.
The motivating concern boils down to: Why do we need coding rules or conventions at all? What happened to the wonderful era of the Renaissance artist-programmer forging their own path, prior to being supplanted by the craftsman and now (even worse) by AI?
In short, there are a few reasons why coding standards/guidelines are useful, and the Renaissance artist-programmer is not entirely gone.

Reason 1: These days, when you’re training a true novice artist, you start out by having them

JSON

JSON (JavaScript Object Notation) is a lightweight, text-based format designed for structured data interchange. It represents data objects consisting of key–value pairs and arrays, and it is entirely language-independent.

Data is at the heart of the digital transformation sweeping healthcare. Radical change requires a new foundation to handle the massive data demands of modern healthcare.

Time to market is crucial as you develop the next therapeutic breakthroughs, genomic insights, and intelligent clinical workflows. You need to deliver them now.

That’s why we’ve extended the power of our InterSystems IRIS Data Platform to address the unique characteristics of healthcare information. InterSystems IRIS for Health is the world’s first and only data platform engineered specifically for the rapid development of healthcare applications to manage the world’s most critical data.

I installed and configure CodeTidy in my local development environment, without InterSystems source-control (git-source-control) and only git for source control.

I would like to use only CodeTidy to stablish an automated  Linting and Code Style Validation for InterSystems ObjectScript code triggered by GitHub Actions.

Could you shed some light on how to accomplish that?

I have a table with 5M rows, the table contains lab observation codes and display names, both columns have type varchar(2000) and both are indexed.

The query looks like:

select code_1_text, count(code_1_text)
  from demo.observation_lab
  group by code_1_text
  order by 2 desc

The table contains ~1000 distinct display names.

It takes 4 minutes for the query to complete on a VM with some pretty old Xeon, 4 cores, 32G RAM, NVME SSD and Linux on board.

Isn't it too slow?
