InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
Hi everyone.
This is a full example how to use a %ScrollableResultSet for results pagination using %DynamicQuery:SQL and build a JSON response including page details.
Feel free to use, share, comment or improve it.
In cache studio there are features, dialog boxes, that help map data from a global to class properties.
I have used %CacheSQLStorage quit a bit, or have in the past, to map globals to classes.
I haven't been able to find a similar feature in VisualStudio.
Do I need to upgrade to IRIS to be able to use VisualStudio to map global properties to classes?
Thanks for your time,
Richard
In the Business Operation, how do we get to know which source is currently sending primary request if there are multiple requests coming at the same time?
In the next few weeks, my coworkers are planning to start using VSCode to code with InterSystems' products. Among the many advantages of that, I would emphasize being able to connect with other technologies, such as GitHub, with ease. Besides, VSCode also offers an extensive extensions store, where you can find many free add-ons that make coding faster and more efficient. Last but not least, to conquer the heart of every developer, it is open source.
With that being said, let's start the tutorial. Feel free to skip some steps if you're comfortable doing them alone.
Hi all,
For a requirement of the customer, we have a BS Rest api with a lot of methods, we need to get the IP of the caller, the method and what is the time that the API has taken to process.
I've found the event onPreDispatch where I can take the IP, ClassMethod, etc.

Visual Studio Code (VS Code) is a free source code editor made by Microsoft for Windows, Linux, and macOS. It provides built-in support for JavaScript, TypeScript, and Node.js. You can add extensions to provide support for numerous other languages including ObjectScript.
The InterSystems extensions enable you to use VS Code to connect to an InterSystems IRIS server and develop code in ObjectScript. The Visual Studio Code Documentation is an excellent resource on VS Code, so it is a good idea to be familiar with it.
Hello,
First of all thanks for your time and help with this question.
We wonder how could we convert a String which represents an XML, to a class which extends from Ens.
Hi,
I am having an issue when I am publishing data to FHIR which is hosting in AWS. I am sending the data to the Cloud FHIR url but getting the below error.
Any idea how to resolve this issue? Any example to cretae FHIR repository using Object script?
:<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>404 Not Found</title> </head><body> <h1>Not Found</h1> <p>The requested URL was not found on this server.</p> </body></html>
I need to write test cases for Object script but need help for understanding the mock library in IRIS? Or need Suggestion for how to use mocking
Hello everyone,
I am looking for the syntax or the way to use a class created in the "BNA" Namespace (my application) from the %SYS Namespace.
Here is the context:
I have a "BNA" application contained in the "BNA" NS, this application provides a user creation functionality. This feature creates both the user in a table in the application and in the Iris system.
I created an initialization script for my database to be able to reset it at will, this script starts by emptying the database of this data, then initializes the basic data.
Hi Developers!
I want to share with you the approach you can use working with Unit Testing which I personally find very convenient and robust.
Will not talk much here about Unit Testing, we have documentation, enough good articles on the topic not only on the Internet but here on Developers Community too, e.g. this one.
How can you manage the Unit Testing of your ZPM module?
This is pretty handy with ZPM. It has a special command "test" which runs all the tests you mentioned in the module. You can execute it as shown below:
zpm:USER>module-name test
And this command runs all the tests you mentioned in module.xml.
Let's see how it works.

Work Queue Manager (WQM) is a feature of InterSystems IRIS that enables you to improve performance by distributing work to multiple concurrent processes programmatically. The idea is that you split the work into chunks, and WQM distributes the chunks across worker processes and can provide the info that the work is done.
However, recently, I got an interesting question: there's a large logical transaction composed of ~1,000,000 individual objects and SQL inserts and updates. Some updates are CPU-intensive, so the original idea was to use WQM to split an update into chunks to speed things up.
But, here's a catch: if one of the individual 1,000,000 changes fails (there's a variety of application-level checks so that it can fail, and that's not even that abnormal a behavior), the entire transaction must be rolled back. That creates a problem: each chunk must report success before committing their individual transactions, and someone must get all these reports and decide if we are committing or not.
Unfortunately, it looks like WQM does not have a bidirectional communication between workers and manager, so I suggested an approach using events:
I had a question about using ZSTART, ZSTOP, and ZMIRROR.
Hi Everyone,
My name is Vignesh and I'm from Virtusa HR Team, we are hiring for a InterSystems Developer in US (Remote), If anyone is interested You can share your resumes avignesh@virtusa.com, also refer your friends.
-Building new and debugging and fixing existing HL7, CCD and custom data interfaces (JSON and XML) to internal and external destinations.
Most server-client communication on the web is based on a request and response structure. The client sends a request to the server and the server responds to this request. The WebSocket protocol provides a two-way channel of communication between a server and client, allowing servers to send messages to clients without first receiving a request. For more information on the WebSocket protocol and its implementation in InterSystems IRIS, see the links below.
Hi Community,
Can anyone point me to the docs that show how to add automatic class documentation for the arguments used in a method call? I can auto document the class, methods, properties etc. with the "///" but can't figure out how to get the nice argument documentation for the arguments used when calling a method.
Thanks in advance
I am sending an httpRequest from ObjectScript to a python server. I am not receiving a response in OS
OS config On the client side
// Create an HTTP request object
Set httpRequest = ##class(%Net.HttpRequest).%New()
// Set the server URL
Set httpRequest.Server = "http://127.0.0.1:8080"
// Set content type to JSON
Set httpRequest.ContentType = "application/json"
// Clear any existing entity body"{""name"": ""Lowell Buschert"", ""dob"": ""1970-12-09"", ""address"": ""XXXXX""}"
do httpRequest.EntityBody.Clear()
//Set httpRequest.
I save / compile a class and instantly run a debug. No issue
A few seconds later, try to run the same debug and get presented with either:
1) Target Source is not compiled (Open launch json) dialog box
OR
2) The version of the file on the server is newer.
In the meantime I have made no edits to the VS Code window at all.
If I pull a compare in response to #2 above, I am presented with a bunch of extent info built into the storage definition similar to the lines below.
Hello All
I'm not sure what the best practice is for this. I have a DTL for returning ORUs back to a hospital in a different time zone. They have requested that various timestamps have the time zone offset added to the HL7 format (%q%k, I think). First, I just wanted to be sure the system was aware it was DST. I was able to determine if DST is in effect like this:
Our 3M Computer Assisted Coding system goes down on a regular basis for updates, the Applications folks like us to Disable the Business Operations when this happens and start them back up when they page the on-call person. The Business Operations have to be started in a sequence to guarantee that all the ADT being sent it processed before we start sending everything else.
Hi Community,
What is Defination of XData which we use using in Object script
we are using XData MessageMap and XData DTL
How can we use XData for different functionalities
Thanks,
Joe
I have some code written in objectscript but need to trigger it from clinical viewer. Someone does a search for a patient with a not found response which then triggers the code

setI recently realized it's been far too long since I talked about the latest features in the InterSystems ObjectScript Extension for Visual Studio Code.
I'm pleased to announce version 2.12.1 of the ObjectScript extension, containing a number of enhancements that make a developer's life easier. Some highlights are described below, including the #1 requested feature from Global Summit -- XML import!
As always, find the full list of modifications in the CHANGELOG, including many bug and vulnerability fixes.
“I have been waiting for thirty seconds for service. This is outrageous! I am leaving!”
“I am very sorry to hear that, sir. Perhaps, next time, you should make a reservation.”
If you heard that comment at your favorite restaurant, you would think the person saying it was being ridiculous. However, in the context of your API, it makes perfect sense. Just like your favorite eatery, your API has some regular patrons who, as you know, will be visiting one day or another. It would be great to be able to make a standing reservation for them as well.
It will involve a couple of IRIS fundamentals.
Hi Community,
Is there a way to call HL7 Data transformation directly from Business service without using Rule functionality in the production
In this scenario i need to call a data transformation in directly in business service and give the transformed message to Business operation
Please share if you have any ideas to implement this.
Thanks,
Smythee
Hello everyone!
I need to transform a String, which is a numerical value, to an Integer.
The value gets returned in my Rest service as "testingID": "1234567", but I need it to be "testingID": 1234567
Thanks beforehand! Appreciate all the help I can get! :)
Does the GetValueAt method of an EnsLib.HL7.message object change the contents of the HL7 message?
We want to do two things, given an incoming HL7 message, in our production:
set""""
If we sequence these as (1) generate XML, (2) extract value using GetValueAt, it works.
