#ObjectScript

The Lo-Code Challenge

Imagine the scene. You are working happily at Widgets Direct, the internet's premier retailer of Widgets and Widget Accessories. Your boss has some devastating news, some customers might not be fully happy with their widgets, and we need a helpdesk application to track these complaints. To makes things interesting, he wants this with a very small code footprint and challenges you to deliver an application in less than 150 lines of code using InterSystems IRIS. Is this even possible?

Your Mission

Let's pretend for a moment that you're an international action spy who's dedicated your life to keeping the people of the world safe from danger. You recieve the following mission:

Good day, Agent IRIS,

We're sorry for interrupting your vacation in the Bahamas, but we just received word from our London agent that a "time bomb" is set to detonate in a highly populated area in Los Angeles. Our sources say that the "time bomb" is set to trigger at 3:14 PM this afternoon.

Every time I try to update an SQL table using odbc connection, I'm getting: ERROR <Ens>ErrException: <MAX $ZF STRING>zPrepareW+1^%Library.SQLGatewayConnection.1

I'm trying to project a series of objects and nested objects to XML, and I'm having difficulties getting the XML representation exactly the way I need it to be. Here's what I'm working with, nothing complicated:

Hence the question: is there a way to do that?

The goal is to get data (from half a thousand to 3-4 thousands lines) from DB, calculate standart deviation then use it as logical condition in analyzer.

For example IF std > custom_value = show_the_result ELSE null

There is a STDDEV(MDX) method used in Analyzer but it is a measure and it can not be used as logical condition (correct me if i am wrong)

Hello,

Is there a programmatic way (in ObjectScript) to determine if a string is an SQL reserved word (aside from using embedded SQL to try to name a property with that string and look for the error :-))?

Thank you,

Jean

Throughout the forum, I find examples of using the method getSegmentByIndex to get the segment as I loop through the HL7 message segments.

Today I spent way too long trying to figure out why I could not modify the segment with this same method. I reached out to my more experienced team and I showed where I got the base code from what I was doing, but I myself could not find the documentation of the method.

i am trying to embed a dynamic SQL into Objectscript code , but the %NEXT() will return 0 , however when i copy the same query and run it in the SQL bit it will give me the result i want
the code :

Our TEST environment and PROD environment are on two different versions of HealthShare Health Connect.

Hello,

I'm trying to carry a custom error from one business process to another.

BPL:LookupClass fails it's lookup and a custom error of "Lookup XYZ" is generated.

The class quits with that error, but upon quitting, the custom error gets wrapped in an Ensemble System error:

ERROR <Ens>ErrBPTerminated: Terminating BP LookupClass # due to error: Lookup XYZ

In ObjectScript you have a wide collection of functions that return some value
typically:

set variable = $somefunction(param1,param2, ...)

There is nothing special about that.
But there is a set of functions that I classify as LEFT SIDED
The specialty of them is that you can use them also on the left of the equal operator
as a target in the SET command:

set $somefunction(param1,param2, ...) = value

Hi folks!

Often, when we develop commercial solutions, there is a necessity to deploy solutions without source code, e.g., in order to preserve the IP.

One of the ways how this can be achieved is to use InterSystems Package Manager.

Here I asked Midjourney to paint an intellectual property of software:

How this can be achieved with IPM?

In fact, this is very simple; just add the Deploy="true" clause in the Resource element in your module.xml manifest. Documentation.

I decided to provide the simplest possible example to illustrate how it works and also to give you a development environment template to let start building and deploying your own modules without source code. He we go!

This story has followed me for more than 20 years.

In the early days of ObjectScript, the volume of $Functions was limited.
You had to write it as part of your program.
But the functionality was often implemented. It just had no name.
To use it, you had "system" calls using $ZU() functions. See Reference
