Showing dates in missing periods

When we collect temporary data (the number of purchases in the store, the number of comments on the post), it may happen that there is no data for a certain period of time. In this case, this time period (hour, day, month) is not represented in the database, that is, there is not a single row for this period. In other words, there are no rows in the database for this period.

How to use the IRIS Native API in Python to access globals and plot some charts.

Why Python?

With a large adoption and use in the world, Python have a great community and a lot of accelerators | libraries to deploy any kind of application.

Hi Community,

New video, recorded by @Stefan Wittmann, is already on InterSystems Developers YouTube:

Recently I needed a classmethod that returns annotation value based on a name of a activity.

As doing it at runtime seemed inefficient, I wrote compile-time utility that iterates over all business process activities and generates relevant code.

This code could be used in a variety of situations when you need to iterate over business process activities, just add it as a secondary superclass to your BPL processes.

I successfully installed IRIS Community edition on my new RYZEN7 desktop. However when I try to start IRIS I get an error event that states IRIS cannot start due to too many cores. (I have 15 on this CPU).

So how do I resolve this? I do have to install the image onto a single core? Or how many cores can this version run on?

Any comments/suggestions or hysterical laughter will be very much appreciated.

Thanks,
Gary Marston

Hello,

We have a need to track Database changes over time - down to the SQL level of granularity if possible. Such as: User xyz runs routine ^abc and we get something similar to a changelog that tells us: table A had this value updated, insert, update etc....

Is that possible using IRIS level tools (Audit Log, Journal File, etc...) , is there a way to convert the global sets and kills from the journals into SQL level changes?

Have you ever needed a math function but could not find what you needed and ended up writing your own? Look no further! ObjectScript-Math is here to solve all your math related function needs.

ObjectScript-Math is an Open Source library for ObjectScript Math functions. It is now available on Open Exchange. This library contains a mix of new functions that are not currently available and functions that are available. The existing functions will be wrapped for use from ObjectScript-Math so that all Math functions can have a central location.

This library will continue to grow, so give it a try and give your feedback!

Don't see what you are looking for? Please feel free to submit requests for additional functions or contribute code yourself!

¡Hi everybody!

As you likely are aware, the new version of InterSystems IRIS for Health (I4H) it's already available in Docker Hub. It's the Community version and is free and fully functional. There have been comments about it in other articles and posts,... so today I won't add anything about features. Here I want to explore "the mistery about the disappearance, or better, absence of our persistent data when we run a container with the durable option" (I didn't find a terrifying font to emphasize the thriller... post editor is not terrific for styling smiley ) .

In today's landscape, enterprises have grown substantially in scale, amassing vast amounts of data. This data is collected from a plethora of sources including different applications, databases, and other channels. Given the diversity and volume of this data, it's only logical for these enterprises to seek a deeper understanding of what their data entails. Some of the data can be stored in IRIS, and it can be reasonable to be able to add this data to a data lake too.

The Internet now offers many different tools for such tasks, that do not yet support IRIS, but it's achievable.

I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.

I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:

Kinds of properties in IRIS

InterSystems IRIS has quite a few different kinds properties. Let’s put them in order so that they make better sense.

First of all, I would divide them into categories:

  • Atomic or simple properties (all those %String, %Integer, %Data and other system or user datatypes)
  • References to stored objects
  • Built-in objects
  • Streams (both binary and character)
  • Collections (which are divided into arrays and lists)
  • Relationships (one-many and parent-children)

Some of these kinds of properties are quite straightforward. For example, atomic properties:

Property Name As %Name;
Property DoB As %Date
Property Age As %Integer

I am trying to investigate whether the SAM component will give us metrics that we are looking for when it comes to # of messages, etc... I have IRIS 2022.1 running on Red Hat 8, but noticed that SAM was bundled as a docker-compose image. REL 8 doesn't install docker off the bat, but has podman which reading podman 3 versions and later, I should be able to call docker-compose.yml images. After installing Apache and making some modifications to docker-compose.yml, I tried executing the start.sh script after verifying podman was running and podman-compose was installed.
