Hello developers, I'm a newbie to Intersystems technologies and I started to work with Caché and Ensemble, and to be more specific I'm working with systems integration. In a scenario where I need to develop new software from scratch, would it be better to develop this new software using REST APIs? Does anyone have any recommendations about courses?

I read under Topics and Rules of InterSystems Datasets Contest:

• Class naming convention. Start the class names with: dc.data.your_name.class. E.g. if there is a dataset on trading data the class names could be: dc.data.finance.transaction, dc.data.finance.instrument.

I created a class “dc.data.finance.transaction”.I expected that it would not compile, because I remembered “Date” was a reserved word in SQL, and one of its properties was named “Date.”  To my surprise, the class compiled successfully.

I have a csv file with 13 columns.

The header row is:

"Date","Check","Merchant","Category","SubCategory","Memo","Credit","Debit","Bill Pay","Debit Card","Account","Balance","Status"

The first data row is:

"","","","","","","","","","","Cash","56",""

I have created a SQL table to LOAD DATA into. When I ran

LOAD DATA FROM FILE '/irisrun/repo/data/finance-transactions-08-Jan-2022_08-25.csv' into dc_data_finance.transact

I got Cash into “Account” property (correct) and I saw 56 in “Status” property. I want to skip the “Balance” column. I updated my LOAD DATA statement to:

LOAD DATA FROM FILE

or "So you just got yelled at by your boss, for sending him an unformatted Hello World webpage"

Our previous lesson ended with us serving a Message value obtained from a Caché REST service to the client, using Angular as a runtime.  While there is a lot of moving parts involved in this process, the page is not especially exciting at the moment.  Before we can start adding new features, we should take a step back and review our tools.

This tutorial is using the JSON functionality built into 2016.2+ versions of Caché.

I need to pull .zip file and unzip it to access the zip files contained in the archive using the web service call. Can any one suggest is there any option for to get the zip files.

I use Microsoft Query via Excel to query an Intersystems database. 

Since upgrading from CACHE to Intersystems, lots of reports fail to refresh twice - by which I mean I can open the report (which may have several separate queries) and query the database once, and then it will refuse to reconnect.

I get:
[IRIS ODBC][State : S1000][Native Code 417] .... Access denied

If I then close and reopen excel, I can run the query again.

If I test the odbc connection between refresh attempts, the connection is successful.

To make matters more confusing, this happens on almost all devices, but not a few high

Hi Friends ,

We have requirement to convert source hl7 message to target json message using dtl.

Currently I have created persistent cls for json and completed the dtl.

DTL giving output as json equivalent xml.

Now how to convert DTL result xml object to json?

set oStream = ##class(%Stream.GlobalCharacter).%New()
set json = pResDTLresponseXml.%ToJSON()
set tSC = ##class("%ZEN.Auxiliary.altJSONProvider").%WriteJSONFromObject(pResDTLresponseXml,.json)
set tSC = oStream.Write(json)
if $$$ISERR(tSC) $$$LOGERROR("Error convert dynamic object to JSON stream: "_$System.Status.GetOneStatusText(tSC))

Hi all,

I am busy trying out the %UnitTest.TestProduction class to implement some automated production testing.

I have a scenario which I am not sure how to get the final results of for assertion. Below is the scenario I am trying to test, with comments on what I have done.

• Receive a  request on a service (Service A).
• Send the request to the BPL
  • I use SendMessage of the TestProduction class.
• The BPL sends a request to a Business Operation (SendToProvider)
• The SendToProvider operation sends a message out to the Service Provider.DeferResponse is done.

I am trying to connect to an external SFTP. They have our public key and I have the private key which is password protected. I have the credentials set to the sftp username and the password to the private key.

If I set the private key only, I get a username/password error connecting. If I set both the public and private key files, I get the error below:

ERROR #7510: SSH Error '-19': SSH Error [80101013]: Callback returned error [80101013] at Session.cpp:418,0

I have this working perfectly using filezilla, however I can't get it to work with EnsLib.FTP.PassthroughService.

Hello Everyone,

In October 2021 we asked for input from the IRIS community regarding exam topics for our InterSystems IRIS System Administration exam. We will close the window for providing feedback on the exam topics on Wednesday, January 12, 2022. Thus, if you would like to have your say in what topics are covered on the exam, this is your last chance!

Extra perk for US-based, non-InterSystems employees: To show our appreciation for helping us validate our exam design, we will offer the first 20 volunteers that complete the survey a $50 gift card. The gift card is a Tango Card that can be

Hi Developers

As you know it's very easy to publish a package to the Developers Community registry. 

But how to test it before publishing?  How to be sure that everything you introduced into module.xml is installed properly?

See the step-by-step instruction below!

For those of you who might be new to IRIS, and even those who have used Cache or IRIS for some time but want to explore beyond its usually-assumed boundaries and practices, you might want to dive into this detailed exploration of the database engine that is at its heart, and discover just what you can really do with it, going way beyond what InterSystems have done with it for you. 

You'll discover that it's actually a hugely powerful yet incredibly simple storage engine that allows you to model any kind of database you wish, once you understand and master its simple, basic principles.

Hey Community,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in December 2021:

We’ve already considered how to run an IRIS-based application in GCP Kubernetes in Deploying InterSystems IRIS Solution into GCP Kubernetes Cluster GKE Using CircleCI. Additionally, we’ve seen how to run an IRIS-based application in AWS Kubernetes in Deploying a Simple IRIS-Based Web Application Using Amazon EKS. Now, let’s look at how to deploy an application to the Azure Kubernetes Service (AKS).

What is the correct data type for decimal numbers precision 5?

I tried %Numeric with Scale 5, but not worked, see:

The "Download Caché Evaluation" at the top of this forum takes the user to a page that only allows her to download versions of IRIS. What am I missing here? Does IRIS encompass Caché? I've wandered around both on the main website and in the Developer Community site looking for a way to only get Caché... Very frustrating.

I appreciate any help you all can provide. Thanks!

Hey Developers,

Ready to participate in our annual December competition?

Join the Advent of Code 2021 with InterSystems and participate in our ObjectScript contest to win some $$$ prizes!

So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.

1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.

2. I'm not really confident enough to create JSON Type classes or backporting code, etc.

I created a dummy class and I need my JSON to look like this:
{
    "notanumber":"28001",
    "aboolean":true,
    "anumber":12345,
    "adecimal":1.2,
    "adate":"01/01/2023",
    "adate2":"01-01-2023",

Hello everyone! Don't miss the Developer Community Post Digest for December 2021.

Hey Developers! Here is a digest of new solutions and applications submitted to the InterSystems Open Exchange in December 2021.

Hello,

I have a question about defining properties for various of services, operations and processes in Productions.Let’s say I have developed a container running an IRIS instance with a single namespace and a production with pre-defined set of components.I’m planning to deploy this container to dev, staging and production environments.These different environments use different settings for the operations, etc.For example, dev-environment could use some test endpoint for an HTTP component, e.g.https://testdomain.com/test and production environment https://proddomain.com/prod.
