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.

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:

Hi all,

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

We have:

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:

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.

Hi Guys,

Not sure what should be the url format, but I'm using : https://PBS.products.com:2188/ to post to the below Business Service

But I'm getting "connect ECONNREFUSED 3.209.112.146" error, so am I missing something?

Thanks

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?

Hi,

sometimes we need more then one Iris container at the same time. Since as containers they always have the same instance name shown in the management portal, it is hard to distinguish the management-portals of the instances. Searching for a way to make it easier I thought I could change the instance name shown in the management portal. I tried "iris rename" in different ways but could only change the configuration name which is shown by "iris list", not the name in the management portal.

If you want to find out what exact version your Docker image is (and since the latest image tagging scheme you cannot just rely on the image tag; and assuming you don't want to actually run it just in order to find out) you can run this docker command:

When I install the numpy package on Python on my PC using:

pip install numpy

I can use it in python on my machine. If I do:

pip install --target C:\InterSystems\IRIS\mgr\python numpy

I get errors any time I try to import it in embedded python.

Overview

The typeorm-iris project provides experimental support for integrating TypeORM with InterSystems IRIS, enabling developers to interact with IRIS using TypeORM’s well-known decorators and repository abstractions. This allows a more familiar development experience for JavaScript and TypeScript developers building Node.js applications with IRIS as the backend database.

While the project implements key integration points with TypeORM and supports basic entity operations, it’s not yet battle-tested or suitable for production environments.

IrisTest is a light weight, powerful, user-friendly tool designed to simplify unit test report generation. It includes an interactive shell and API to facilitate communication, allowing developers to easily manage and generate reports for their test runs in various formats. Whether you're debugging or creating detailed reports for analysis, IrisTest makes the process smooth and efficient!
