$ZTRAP vs Try/Throw/Catch

I'm scraping my way through some code that's been around for a while, and came across the use of $ZTRAP and (dear GOD) GOTO for trapping and handling errors.

In an effort to "modernize" it and make it, I don't know, less M-ish (sorry old-timers!), I'm replacing it with Try/Catch blocks.

Some questions:

  1. Is this a dumb idea?
  2. Anything I should look out for?
  3. Did I hurt anyone's feelings?

And if the answer to number 3 is Yes, my deepest apologies ... I love you guys! 🤩

Hi Developers!

This is the second post on the resources for Developers. This part is about Open Exchange

Using Open Exchange to Learn InterSystems

InterSystems Open Exchange is a applications gallery of tools, connectors, and libraries which InterSystems Developers submit to share the experience, approaches and do business. All the applications are either built with InterSystems data platforms or are intended to use for development with InterSystems data platforms.

If you are a beginner developer you can take a look at applications in Technology Example category. All the applications in this category come with open source code repositories, so you are able to run the samples and examples in a docker container with IRIS on your laptop or in the cloud IRIS sandbox. Examples:

I would dearly love to avoid manually creating a SEF or XSD file to get the X12 832 (4010) schema into IRIS, but I have been hard pressed to find either downloadable resources or commercial options. The typical recommendation, edi-dev, seems to just do tooling that will help create SEF files, but no longer sells actual SEF files.

Anybody got any good resources that might have these schema files?

Thanks for any help!

Cordially,

Jonathan

Let's say I have an InterSystems IRIS instance with 6 Namespaces:

  • Foo1
  • Foo2
  • Foo3
  • Foo4
  • Foo5
  • Bar

And the number of Foo# namespaces can increase at any time for a number of reasons. I need to ensure that they all have identical configuration globals stored in a DB called CONFIG, so I do the following in my configuration file:

[Map.%ALL]
Global_SYS=%DEFAULTDB
Global_SYS("CommonConfig")=CONFIG
Global_SYS("CommonOtherSettings")=CONFIG
Global_SourceControl=CONFIG

Hello everyone,

Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.

Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.

Recently I wanted to get a list of all cached queries and their texts. Here's how to do that.

First create an SQL Procedure returning Cache Query text from a Cached Query routine name:

Class test.CQ
{

/// SELECT test.CQ_GetText()
ClassMethod GetText(routine As %String) As %String [ CodeMode = expression, SqlProc ]
{
##class(%SQLCatalog).GetCachedQueryInfo(routine)
}

}

And after that you can execute this query:

Hello Community,

I have encountered the following SQL problem trying to create a table from a SELECT statement.

I narrowed the problem down to the following example:

1. The SELECT statement alone works as expected.

SELECT m.Name, h.Status 
FROM EnsLib_HL7.Message m, Ens.MessageHeader h 
WHERE h.MessageBodyClassName='EnsLib.HL7.Message' AND h.MessageBodyID = m.ID

2. But if "CREATE TABLE ... AS" is added it fails

We have an operation that sends a Rest request to an external endpoint. The request includes the secret, which shows up in the Message Viewer. While access to the Production is restricted to only those who need it, we have been asked to remove it from the Message Traces. Is there a way to hide certain information on the Message Viewer ?

Thanks for reading

Hi,

I will try to explain my problem. I have a Main ZenPage on one server that has 2 buttons: each button will launch a different ZenPage on a separate server in an iFrame. All 3 servers have the same user.

Currently, the user logs in to the Main ZenPage, but when they click either button to launch the other ZenPage on the separate server they get the login screen again to login to that server.

Is there anyway I can pass the credentials from the Main ZenPage to the child ZenPages, so that the user doesn't have to login again? Thanks.

Hey Community,

Watch this video to learn how the InterSystems AppServices team migrated a data lake powering a suite of marketing reports off of Microsoft SQL Server to InterSystems IRIS, leading to such benefits as lower maintenance, better performance, and a better overall development fit:

Hi Developers!

Recently I was asked, “How can a beginner in InterSystems technologies learn from InterSystems Developers community content to improve his developer skills”?

This is a really good question. It has several answers so I decided to write the post with the hope it could be useful for developers.

So! How to learn Intersystems Data Platforms(IRIS, IRIS for Health) from InterSystems Developers community content if you are a beginner?

For some time I have been planning to do some type of proof of concept with the Workflow functionality, which, like so many other functionalities present in IRIS, tends to go quite unnoticed by our clients (and for which I say mea culpa). That's why I decided a few days ago to develop an example of how to configure and exploit this functionality by connecting it with a user interface developed in Angular.

Hi

I have a question about terminal, when I run a class from it that contains an error I get a report of error as I would expect, and then an apparently random three letter code is appended to the namespace name in the prompt, as shown below.

GMMHTIE>do ##class(temp.Nothing).What()

w !, tParisAnswer
^
<UNDEFINED>zWhat+23^temp.Nothing.1 *tParisAnswer
GMMHTIE 2d1>

Then, when I try to enter a command I get an error

Note: this was originally posted on June 5, 2024 but presented as being posted on May 9, 2024 so this re-post fixes the date.

Recent updates to the Intersystems Language Server introduce many significant enhancements aimed at improving developer experience and productivity. I'll talk about some of the key ones here, while the complete list, including numerous bug fixes, can be found in the Language Server's CHANGELOG.

Hello IRIS Community,

InterSystems Certification is developing a certification exam for InterSystems IRIS SQL specialists, and if you match the exam candidate description given below, we would like you to beta test the exam. The exam will be available for beta testing on June 9 - 12, 2024 at InterSystems Global Summit 2024, but only for Summit registrants (visit this page to learn more about Certification at GS24). Beta testing will open for all other interested beta testers on June 24, 2024. However, interested beta testers should sign up now by emailing certification@intersystems.com (please let us know if you will be beta testing at Global Summit or in our online proctored environment). The beta testing must be completed by August 2, 2024.
