All time

I have a business process that adds data to a global variable on receipt of an HL7 message, and a scheduled task that executes a class method defined within the same business process that removes data from the same global variable. With this in mind it makes sense to consider concurrency and therefore make use of the LOCK command.

My first question is whether this is actually necessary?

Hi Community,

Here is a brief walkthrough on the capabilities of IRIS AI Studio platform. It covers one complete flow from loading data into IRIS DB as vector embeddings and retrieving information through 4 different channels (search, chat, recommender and similarity). In the latest release, added docker support for local installation and live version to explore.

artisan cover

If you’ve ever watched a true artisan—whether a potter turning mud into a masterpiece or a luthier bringing raw wood to life as a marvelous guitar—you know that magic isn’t in the materials, but in care, craft, and process. I know this firsthand: my handmade electric guitar is a daily inspiration, but I’ll admit—creating something like that is a talent I don’t have.

If you're migrating from Oracle to InterSystems IRIS—like many of my customers—you may run into Oracle-specific SQL patterns that need translation.

Take this example:

SELECT (TO_DATE('2023-05-12','YYYY-MM-DD') - LEVEL + 1) AS gap_date
FROM dual
CONNECT BY LEVEL <= (TO_DATE('2023-05-12','YYYY-MM-DD') - TO_DATE('2023-05-02','YYYY-MM-DD') + 1);

In Oracle:

Alert: SQL Queries Returning Wrong Results

February 19, 2025 – Alert: SQL Queries Returning Wrong Results

InterSystems has corrected two issues that can cause a small number of SQL queries to return incorrect results. In addition, InterSystems has corrected an inconsistency in date/time datatype handling that may lead to different, unexpected – yet correct – results for existing applications that rely on the earlier, inconsistent behavior.

Exclude globals from mapping

Hi

I've more than 100 classes that are packed like CRD.Health.MyClass so I've defined the global mapping as CRD*, but now I would like to map some of the classes (CRD.Health.SomeClass) to different database so how can I exclude it from my current mapping to be in the new one because if I map it in the new database it will still conflict with the old mapping?

Thanks

It is probably somewhere in the doc. So hard to search. Hope InterSystems going to AI on their community/support data.

How to see a meaningful value in management portal - sql explorer. For instance

Property Name As %String;

Class MyObj Extends %Persistent{

If one of your packages on OEX receives a review you get notified by OEX only own YOUR package.
The rating reflects the experience of the reviewer with the status found at the time of review.
It is kind of a snapshot and might have changed meanwhile.
Reviews by other members of the community are marked by * in the last column.

I also placed a bunch of Pull Requests on Github when I found a problem I could fix.
Some were accepted and merged, and some were just ignored.
So if you did a major change and expect a changed review just let me know.

I am trying to get a list of databases using the DatabaseByServer method but I am only getting an empty string. I have not found any useful examples of the proper usage of this class/method.

I have tried 2 formats. First

set dbList=""

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList)

I also tried:

set db=##class(Config.Databases).DatabasesByServer("my-host",.dbList,"/cachesys/")

In each case dbList is empty string. I can not figure out what I am missing.

The Power of Indexing in Database Tables

When working with databases, most developers understand the concept of an index and why it's used: to speed up data retrieval. But the real impact of indexing often becomes clear only when you compare scenarios with and without it.

Do you Know what Happens Without an Index?
Imagine a table with three columns: Name, Age, and MobileNumber.
