ObjectScript has at least three ways of handling errors (status codes, exceptions, SQLCODE, etc.). Most of the system code uses statuses but exceptions are easier to handle for a number of reasons. Working with legacy code you spend some time translating between the different techniques. I use these snippets a lot for reference. Hopefully they're useful to others as well.

Is it possible to save HL7 messages to a csv file? Record Mapper appears to allow a service to import a csv and convert to HL7, but can you reverse that and save to a csv?

This is a basic JavaScript Vue.js example how you can use REST calls using plain HTML.

Hi,

I've heard from two different sources the SMP (or parts of it) and for sure the DTL front end (in studio? via SMP?) have been rewritten to be more modern. But on a latest IRIS Community download everything looks the same to me. Am I missing something or is this Marketting Spin?

^{Hopefully I won't get banned for this post aswell......}

I am generating the DDL from a modeling tool - ERStudio. But the DDL has 2 issues right now.

DROP TABLE schema_name. CASCADE CONSTRAINTS;
The Constraints is not supported but works with the statement - DROP TABLE Study_Definition.EVENT_STORE CASCADE;

Second if there is no object to drop, it throws an error, so is there a check like in sql server If_Exists that we can use in CacheDB?

Hello,

I've got a table with many attributes and data. There is 10 000 000 registrations approximatly.

I need to make a research on this table with filters, paging, and order.

You can see an example of my SQL request :

SELECT * FROM ( SELECT TOP ALL * FROM ANCV_Data.Titre WHERE etatTitre = 'Emis' ORDER BY numRemise desc) v WHERE %vid BETWEEN 1 AND 25

Cause there are many data on my table, my SQL req is too long if I don't have index on my attributes BUT there are many associations possible...

Hi Community,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in November 2019:

Want to see how IRIS can be used in a radically-new way, as a JavaScript-based Multi-model database?

Take a look at QEWD-JSdb: https://github.com/robtweed/qewd-jsdb

Full instructions on how to try it out on the AWS IRIS Community Edition are included in the repository.

I am writing an API that sends over a very large JSON object.

The code I'm using to get the data is actually used in our production system today for the use of writing a report.

However when I call the code using the API (using SoapUI) I am getting 'Error getting response; java.net.SocketTimeoutException: Read timed out'

The web applications settings have a session timeout setting at 15 minutes, but this is timing out within just a few minutes, so I know it's not hitting this mark.

Hello,

I have a couple of IOT devices that communicate via WebSockets to our backend.

I successfully managed to create a websocket connection between server and (iot)client using %CSP.WebSocket
However I would like to implement authentication on this using the HTTP headers at the same time of Connection: Upgrade.

I tried to set the headers to globals in order to debug but they are always empty.

Example code:

Hi folks,

how do people run iris-community edition nowadays? It seems there are some incantations needed that are not documented here:
https://hub.docker.com/_/intersystems-iris-data-platform/plans/222f869e-...

When I follow these, I am only getting an error:

Hi Developers!

For those who want to participate in the Advent of Code 2019 and code with ObjectScript in IRIS, I created a very simple but handy Github Template.

Use the green button

to copy template in your own repo, clone the repo and run in the repo folder:

docker-compose up -d

you will get InterSystems IRIS 2019.4 Community Edition running with the template classes to load input data from files and Day1 solution.

This is also set up to start crafting solutions of Advent of Code 2019 and edit, compile and debug ObjectScript with VSCode addon.

Happy coding with Advent of Code 2019!

Hi all...

I am try to execute a class method from JDBC connection. My method are simple, just create a file at $HOME like this:

Having developed systems using Caché ObjectScript and Ensemble on various projects over the last 4 - 5 years I'm considering trying for some certifications. I've found details of the Caché Systems Administrator and Caché Application Developer certifications but have a couple of questions:

1) Is there a certification for Ensemble Application Developer?

2) Are any sample questions and/or practice exams available?

Thanks
