What I find really useful about IRIS when teaching my subject of Postrelational databases is the fact that it is a multi model database. Which means that I can actually go into architecture and structure and all that only once but then show the usage of different models (like object, document, hierarchy) using the same language and approach. And it is not a huge leap to go from an object oriented programming language (like C#, Java etc) to an object oriented database.

However, along with advantages (which are many) come some drawbacks when we switch from object oriented model to relational. When I say that you can get access to the same data using different models I need to also explain how it is possible to work with lists and arrays from object model in relational table. With arrays it is very simple - by default they are represented as separate tables and that's the end of it. With lists - it's harder because by default it's a string. But one still wants to do something about it without damaging the structure and making this list unreadable in the object model.

So in this article I will showcase a couple of predicates and a function that are useful when working with lists, and not just as fields.

Here’s our Q2’2024 quarterly platforms update. If you’re new to these updates, welcome! This update aims to share recent changes as well as our best current knowledge on upcoming changes, but predicting the future is tricky business and this shouldn’t be considered a committed roadmap.

With that said, on to the update…

How to understand what's wrong with compilation if the compilator just hides errors?

40 errors, and what do I have to do with this so valuable information?

Hello DC Members,

Hello guys.

Can anyone help me about Global ^Errors? Only in 1 specific namespace is it growing fastly. It grows from 2 to 3 Gb per hour when all services are active. Which commands exactly do this? In another similar namespaces, there is not that Global in the class list.

Thanks.

I downloaded and installed the trial version of Caché.
it is installed in c:\intersystems\Trycache
I changed the system environment settings so that
GLOBALS_PATH = c:\intersystems\Trycache
and PATH includes c:\intersystems\Trycache\bin
Caché works, and I can login, use the globals, etc...

Hi Developer community

Does anyone know where the custom message filters for the message browser live? You can load and save by name and existing filters appear in a list. I want to export them from an existing production and import then into a new one.

Thanks in advance

Has anyone done an ebXML implementation using the out of the box classes?

I would like to hear about your experience and any issues you encountered using the classes provided.

Hi all,

In CSP page we get data from Class via Query method.

<TD valign=top>#(DEOBJ.Get("Comments").Read())#</TD>

Surely you wanted to use the OpenAPI Specification (OAS) JSON you used for your spec class on the iris-web-swagger-ui iris package. The generated OAS from the ##class(%REST.API).GetWebRESTApplication(...) method is very crude, with no description on the parameters or the expected response structure.

So after creating your REST application from an OAS you should have:

All,

I've asked my teammate to open a WRC on this issue, but wanted to open the discussion to see if maybe we aren't the first people to see this issue.

The code we are deploying is a COS object with some Python methods. The code works fine locally on the developer's machine. However, when the business process runs in the server environment, we see the following when COS code attempts to call a [Language = python] method:

Our ERP solution runs on different sql databases (such as ms sql and posgre). We are using the same code for all plattforms, doing database-specific changes in the db driver for each type of database.

There is one function in our program, where the user can store long text to discribe something, which is used in print and web. This text is treated/stored as html and can include pictures. The pictures in the html are stored base64 coded inside the html and the html is stored as text in a column. In other database systems, this is treated as TEXT or BLOB, and workings just fine.

Hi developers!

Those who code IRIS solutions in VSCode using Docker often use the convenient ObjectScript menu, which contains links to Management Portal, Class Reference, Unittest portal, Productions, etc.

While drilling down to a Dev Container to code Embedded Python there is no such option, at least within my settings:

So I don't know how to connect to it.

Thoughts?

Hi everyone, I'll be honest with you I don't have much idea how to do this, but I was asked to install IRIS for Health on an AWS ubuntu machine(ssh -i "teleker-net.pem" ubuntu@xx.xxx.xx.xxx(no I will put the real number)). My boss has sent me the .key and .pem files that I am supposed to need for the installation.
