I am trying to work with Java Selenium through Cache my java programme works fine but I would like to pass parameters to the jar file form my Ensemble production.
Hello all; I am using a one-to-many relationship. I have a Claim (one), in a relationship with Lines (many), but the Claim is storing a list of Lines IDs, rather than the Lines storing the Claim Id. This seems upside down, and not what I expected.
The issue is related to Cache Studio. I wrote a plugin for creating reports using FastReport. The plugin is called via the context menu. In this case, the class is d ## (%ZFastReport.SourceControl) .InstallSorceControllAllNameSpace ().
I was editing the properties of a persistent ObjectScript class the other day and noticed that the storage definition wasn't updating to reflect my latest changes.
In this case, I deleted a property that was no longer needed from the class definition, saved, recompiled, and still saw it in the storage definition.
In the Caché Foundations course, students are learning about Caché Development and ObjectScript syntax at the same time. To help students complete the exercises, we provide an ObjectScript Quick Reference (aka "the Cheat Sheet").
It is not a reference for all of ObjectScript! It is a list of the ObjectScript commands and functions that students use during the course, along with common syntax for objects, collections, etc. It also contains some useful macros.
I'm participating in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during the training. Tips presented in the day 1:
The purpose of this post is to raise the profile of a powerful mechanism that has long been available to us, and to open a discussion about ways in which it can be used or abused.
You can read more detail about the mechanism here. To summarize, your class definition can use the Projection keyword to reference one or more projection classes. A projection class can implement methods that get invoked at key points in the lifecycle of your class.
A concurrent session in IRIS: SQL, Objects, REST, and GraphQL

Introduction
We’ve already addressed the topic of why object/type representation is superior to SQL for implementing subject area models. And those conclusions and facts are as true now as they have ever been. So why should we take a step back and discuss technologies that drag abstractions back to the global level, where they had been in the pre-object and pre-type era? Why should we encourage the use of spaghetti code, which results in bugs that are hard to track down, and which relies only on virtuoso developer skills?
There are several arguments in favor of transmitting data via SQL/REST/GraphQL-based APIs as opposed to representing them as types/objects:
InterSystems IRIS 2019.1 has been out for a while and I would like to cover some enhancements for handling JSON which might have gone unnoticed. Dealing with JSON as a serialization format is an important part of building modern applications, especially when you interact with REST endpoints.
In my previous article, we reviewed possible use-cases for macros, so let’s now proceed to a more comprehensive example of macros usability. In this article we will design and build a logging system.
Logging system
Logging system is a useful tool for monitoring the work of an application that saves a lot of time during debugging and monitoring. Our system would consist of two parts:
Storage class (for log records)
Set of macros that automatically add a new record to the log

We are trying to convert some of our SQL Service Integration Service jobs from Visual Studio to Ensemble. If we execute a Stored Procedure within SQL Server Management Studio it is returning approx 12,000 rows. However when Ensemble executes the same Stored Procedure it is only returning 250 rows.
I have a need to store a password in an object property of a User object.
What would be best practice for data type assigned to the "Password" property and securing that password against prying eyes, both just browsing the global as well as via SQL? Better yet, how can I prevent a specific property from being projected to SQL?
Class Queries in InterSystems IRIS (and Cache, Ensemble, HealthShare) is a useful tool that separates SQL queries from Object Script code. Basically, it works like this: suppose that you want to use the same SQL query with different arguments in several different places.In this case you can avoid code duplication by declaring the query body as a class query and then calling this query by name. This approach is also convenient for custom queries, in which the task of obtaining the next row is defined by a developer. Sounds interesting? Then read on!
We are wondering how to create translation profile for HL7 to SDA in "HEALTH SHARE". can you please help us with the class definition containing the mapping for that(so that we can import directly and understand the mapping).
