I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. I am having trouble with a specific table. When I need to query this specific table for specific fields, I am receiving an error. However, if I change the call to get all columns (`*`), there is no error. I get 37K records returned.

Error:

Hi Community,

In this article, I listed 5 useful SQL functions with explanations and query examples 👇🏻
These 5 functions are

• COALESCE
• RANK
• DENSE_RANK
• ROW_NUMBER
• Function to Get Running Totals

So Let us start with COALESCE function

A question for anyone using InterSystems technology:

What are the biggest challenges you’ve faced either trying to hire developers that know ObjectScript, or trying to train developers on ObjectScript?

Hi Community,

I am new to ensemble development, Can anyone share me few basic Concepts which will be helpful for Converting JSON message to other message types like HL7,XML 

Thanks,

What is the difference between "Apply" button and "Update" button on an Order Item screen?  

Hello everyone,

As someone who is new to the world of InterSystems technology, I have been looking for the best resources to learn more about it.

I have heard great things about InterSystems technology, particularly its speed and scalability, and I want to make sure I have a solid understanding of it before diving in further. From what I understand, the official InterSystems courses cover a wide range of topics and are taught by experts in the field.

Hi Community,

I am new to ensemble and cache object scripts ,i am trying to create a business service using Ens.BusinessService

but i have doubt what is the difference or uses between Parameters and property in defining classes in defining business service

I need to split existing tables from database and put some parts of them into a new namespace. I dont know where to start, other than the installer.cls file. If you can provide clear instructions i would be greatful.
Example:
I have NAMESPACE=NEWTEST and DB

The i need to take TABLES from that DB pull specific data from them and bind it to NEWTEST

Hi InterSystems Developers!

Recently I've updated the FHIR dev template so that it now publishes an IPM package fhir-server that makes the setup of InterSystems FHIR server a trivial manual or automatic or programmatic procedure one command long.

Please see below how you can benefit from it.

TLDR

USER>zpm "install fhir-server"

All the details below.

Good morning,

We have been investigating how to activate a Server to Generate Tokens and an associated Resource Server to Validate the Token. This step, actually we have found out with the invaluable support of @Alberto Fuentes from Intersystems.

Hi,

I

want to get the values from a serial property because my code depends upon the class serial class.

For example

Serial class

Class Data.Serial Extends %SerialObject

{

Property FirstName as %String;

Property LastName as %String;

}

Persistent class

Class Data.Persistent Extends %Persistent

{

Property MPID as %Integer;

Property Name as Name.Serial;

}

Now i need save MPID and Name(Serial class property into SQL Table ) so i am trying the below class

Class Data.TestUtil Extends %RegisteredObject

{

Method Savedata(MPID,FirstName,LastName)

{

Set tSC=0

Set Obj=##Class(Data.Persistent).%New()

Set Obj.MPID=MPID

Hello,

Thank you for reading this question, and thank you for your time and replies.

I was wondering which ways, tools, mechanisms, or vias would you recommend to teach to kids, teens, adults, being your sons / daughters or not; your passion or likelihood for programming and computers?

I know there are some programming free games like the following ones:

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. I followed this Tutorial here, For starters I wanted to copy it as it is and run that as an example but the (Stateless Service Mode Example) is not working within my eclipse environment with errors on the com.intersys. complaining about the service class. If anyone out there has had experience on this please advice all I need to do is be able to invoke my jar file within Cache(In general want to call my  java programme  within Cache

In this article, I would show how you can upload and download files from InterSystems products via http.

The questions about working with files over http arise fairly often on community and I'm usually linking to my FileServer project which demonstrates file upload/download but I'd like to talk a bit more on how we can serve and receive files from InterSystems products.

Downloading a file

If you have a file in on a file system and you know the path you can serve it from REST or CSP context by calling this method:

Hi Community ,

Can anyone please explain how to use EnsLib.EMail.AlertOperation operation to send notification to my email id when any error occurs in my production?

Please give any example how to use EnsLib.EMail.AlertOperation operation class

Hi!

I've encountered a peculiar behavior of $ListNext in Intersystems Cache, where I'm not sure whether I'm doing something wrong, or is it an intended behaviour.

First I am creating a ListOfDT from a string delimited with underscores:

Set tempList = $ListFromString(String, "_")

Then I'm saving the tempList as a property of Persistent object

Do DataObj.Services.InsertList(tempList) (Note that Set DataObj.Services = tempList suggested by the manual didn't work at all)
Do DataObj.%Save(1)

Then I'm trying to iterate over the saved list with $ListNext objectscript function:

Hi ,

I am Converting HL7 message into SDA3 format by using Ens.DataTransform Class but transformation is not happening while using this class and throwing the below error

Good morning,

We would like to share with you a doubt, and we would appreciate if you could read and answer us.

Currently we have a file titled: "Imagen PatientID 9358340 PatientName Milagros ReasonForStudy 350290 InstitutionName 350290  StudyDate 20220927.xml" , in which we have the following InstitutionName:

    <DicomAttribute keyword="InstitutionName" tag="00080080" vr="LO">
        <Value number="1">350290</Value>
    </DicomAttribute>

Once we generate the DICOM file using the command  from the tool named "xml2dcm" inside the DICOM simulator package dcm4che:

Hello, community

To celebrate that this week is "International Week of Deaf People 2022" , https://wfdeaf.org/iwdeaf2022/

Could we do a small challenge?

The statement is:

Task

Give you two strings: s1 and s2. If they are opposite, return true; otherwise, return false. Note: The result should be a boolean value, instead of a string.

The opposite means: All letters of the two strings are the same, but the case is opposite. you can assume that the string only contains letters or it's a empty string. Also take note of the edge case - if both strings are empty then you should return false/False.

Hi,

Over time I have created an house-automation solution based on IRIS:
90% of my code is pure ObjectScript, with the most recent 10% being the use of Python libraries for specific tasks.
All of the above being terminal based up to now.
I would like to expose some configuration options / parameters via a very simple web page, to be serviced with the IRIS private web service (so I don't want to use an external Webserver just for this..)

This is a detailed guide to develop RESTful services using InterSystems Ensemble. The goal of this guide is to make you understanding the basic concept and building blocks of a RESTful service. The service is going to provide a very basic functionality (a “Hello world!”).

You will learn how to create required components as Ensemble classes, configure the run-time as an Ensemble Production and create a service configuration as a web application.

Currently what I have is:

set now = $now()
set ts = $zdt(now,-2) _ "." _ $p(now, ".", 2)

Docs state (for -2 dformat):

Fractional seconds in the input value are permitted, but ignored.
 

Do we have messages.log/cconsole.log projection in SQL?

I was sure we do, but unable to find it.

I was wondering if someone could help me. I do not have docker available to me however a lot of the Open Exchange apps require it. Since I am using a Virtual Windows Machine I can not get docker installed, so I was wondering how to get around this? Someone at GS2022 suggested looking at the docker_compose.yml to figure out how to get around docker, but I am not sure I understand how to read it. 

Does someone have any quick solutions to get around docker compose? Or can tell me how to read a docker compose so that I can install some Open Exchange and or additional InterSystems components?

Thanks
