Hello My Friends,

I have a question how to use order by %DLIST, this is my code:

SELECT

$ListToString(%DLIST(DISTINCT MRDIA_ICDCode_DR->MRCID_Code),', ' ) ICDX,

$ListToString(%DLIST(DISTINCT (MRDIA_ICDCode_DR->MRCID_Desc || ' (' || MRDIA_DiagnosisType_DR->DTYP_Code || ')')),', ' ) Diagnose

FROM SQLUser.PA_Adm

LEFT JOIN SQLUser.PA_AdmInsurance ON (PAADM_RowID = INS_ParRef AND INS_Rank = 1)

LEFT JOIN SQLUser.PA_AdmPackage ON (PAADM_RowID = PACK_ParRef)

LEFT JOIN SQLUser.MR_Adm on MRADM_ADM_DR = PAADM_RowID

We've got some web services that utilise EnsLib.SOAP.Service/EnsLib.REST.Service. These do some further requests to a few operations to call some other services and return the combined results.

An issue that we are noticing is that some of the usage involves users hitting the refresh button a few too many times and generating a lot of requests. This is mostly an issue when the service that the operations are calling are down or slow to respond. IRIS starts using a lot of RAM when this occurs and has caused outages by getting through an extra 50-60GB of RAM.

Hey Community!

We're excited to introduce a new way to interact with the Developer Community AI — you can now have a real conversation with it!

Instead of just asking one-off questions, you can chat with DC AI in a more natural, back-and-forth format. This way, whether you're exploring InterSystems technologies, debugging code, or learning something new, DC AI is here to help, just like a fellow developer.

Hi Developers!

Here are the technology bonuses for the InterSystems FHIR and Digital Health Interoperability Contest 2025 that will give you extra points in the voting:

Using Flask, REST API, and IAM with InterSystems IRIS

Part 3 – IAM

InterSystems API Manager (IAM) is a component that allows you to monitor, control, and manage traffic from HTTP-based APIs. It also acts as an API gateway between InterSystems IRIS applications and servers.

Hi,

I have Objectscript routine stored in an external Linux file which I've called /my/home/DisplayDB.int

This file does not include any Class definitions and is simply a set a Object script routines. I think this is called INT objectscript

The file looks like this:

Hi all,

We have an restriction in a SQL database with a unique index.

We want to catch that exception when it tries to insert or update a value that violates the unique index condition.

Hi, Community!

Does your team need a graphical view of your data? See how to use the InterSystems Reports Designer to create helpful visualizations:

Is it possible to audit code changes in a namespace?

Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).

how can I get the classMethod name ?
like we get class name using "$CLASSNAME($THIS)", same way I need class Method ?

If you are using the client-side development paradigm (i.e. editing code in local files that get imported and compiled onto the IRIS server your `objectscript.conn` settings point to) you can now use IPM in VS Code to manage the packages in your IRIS target by launching it from the Explorer view.
