A feature I recently used in working on ISC internal applications is the ability to send emails on behalf of someone. This is useful when generating system notifications from an application when you want some of them to show up as being from a specific person, perhaps posting comments on a work ticket.

In my case I was updating our facilities work order system for tracking requests. Normally all notification emails are sent from the same noreply email address. I wanted to change that so comments added from the original requester would show up as being from them and stand out.

Hello everyone, I’m a French student in academical exchange for my fifth year of engineering school and here is my participation in the FHIR for Women's Health contest.

This project is supposed to be seen as the backend of a bigger application. It can be plugged into a Front End app and help you gather information from your patients. It will read your data in local and use a Data Transformation to make it into a FHIR object before sending it to the included local FHIR server.

I have a need to dynamically create a web application definition in a namespace using ObjectScript. I am having trouble finding a cache class or routine that let's me do this.

Thanks

Hello,

Recently I tried to connect to JDBC on IRIS 2020.3+ and I came across the following error:

 SQL Error [461] [08S01]: [InterSystems IRIS JDBC] Communication link failure: Communication error: Server closed communication device

This error implies that the port is not open.

Checking with the netstat command:

I get this on some queries in some namespaces. For instance, this query:

It works fine in HSBUS but in HSREG it throws the error.

Server closed communication device

Does anyone know what would cause this? Would it log something more useful somewhere?

In this tutorial, I’d like to talk about Class Queries. To be more precise, about the Queries based on user-written code:

In the next ten years the applications will radically change, see my vision about it:

Today, the web apps are developed using modern HTML 5/CSS/Javascript frameworks like React, Angular, Bootstrap, etc. These web apps are focused on responsive views from the laptop to tablets and mobile screens.

SQLBuilder is a flexible and powerful SQL query string builder for InterSystems IRIS,

With SQLBuilder you have nice and clean object oriented methods, instead of having to use concatenation and substituition to generate dynamic queries.

IRIS is an excellent option for machine learning projects with massive data operation scenarios, because the following reasons:

The cache has error messages default, for example , " -139 SQLCODE : Competition impairment on the update: row versions are not the same. "

How i can exchange it for a more friendly to the user's message? I use the CSP.Page and form_save ( ).

What is best practice for this situation?

Hi!

Is there a method in a persistent class that can return the current number of records/persistent objects in it?

There are numerous ways to interact with InterSystems Caché: We can start with ODBC/JDBC that are available via SQL gateway. There are API for .NET and Java too. But if we need to work with native binary libraries, such interaction is  possible through Caché Callout Gateway, which can be tricky. You can read more about the ways of facilitating the work with native libraries directly from Caché in the article below.

I am playing with json output from result sets

I've generated a dynamic resultset and now doing the json and I can get Array's with nested Objects but I'm trying to get to Objects nested with another object

I have a class to track data changes.
As it becomes slower and slower to find last changes I think I need an index.
The 2 classes are just simplified reality.
HowTo ?
