#InterSystems IRIS

InterSystems IRIS has quite a few different kinds properties. Let’s put them in order so that they make better sense.

First of all, I would divide them into categories:

• Atomic or simple properties (all those %String, %Integer, %Data and other system or user datatypes)
• References to stored objects
• Built-in objects
• Streams (both binary and character)
• Collections (which are divided into arrays and lists)
• Relationships (one-many and parent-children)

Some of these kinds of properties are quite straightforward. For example, atomic properties:

Property Name As %Name;
Property DoB As %Date
Property Age As %Integer

Hello,

I've been stuck on this for a few days so I figured I'd ask for help here.

I have an XMLMessage response from a ProvideAndRegister call which looks like this:

Hi all

I'm having trouble defining the mapping needed to take the very large base64 string in OBX:5.5, and map it to an XML virtual document property that supports Stream.GlobalCharacter. I know from within the DTL you have to use custom code to manage the segment due to its size.

There is an interesting new feature in the recently announced 2024.1 preview, JSON_TABLE. JSON_TABLE is one of a family of functions introduced by the 2016 version of the SQL Standard (ISO Standard, published in early 2017). It allows for JSON values to be mapped to columns and queried using SQL. JSON_TABLE is valid in the FROM clause of some SQL statements.

The syntax of JSON_TABLE is quite large, allowing for exceptional conditions where the provided JSON values don't match expectations, nested structures and so on.

As a result of Evgeny's recent questions regarding the use of QEWD.js with IRIS in another post, I thought it would be a good idea to create a separate post focusing specifically on how to use QEWD.js to create REST APIs for IRIS.

QEWD.js is, of course, a Node.js framework, and all the REST API code can be written entirely in JavaScript.

Our team is reworking an application to use REST services that use the same database as our current ZEN application. One of the new REST endpoints uses a query that ran very slowly when first implemented. After some analysis, we found that an index on one of the fields in the table greatly improved performance (a query that took 35 seconds was now taking a fraction of a second).

Is there any mechanism already implemented in IRIS to prevent XSS exploits ?

This case happen when user input html/javascript content into fields and submit the page. If saved content is rendered as is, it's going to be executed by anyone visiting the page.

What I am looking for :

Hello everyone!

I have set up an EnsLib.REST.GenericService with an EnsLib.HTTP.InboundAdapter which forwards the http requests received by a web app to my Business Process.

I would like to parse HTTP multipart/form messages I am receving and be able to iterate over the various fields within the request body, accessing its content type and the content itself.

As far as I understand I should use the %Net.MIMEReader class which should return a list of %Net.MIMEPart, one for each field within the request. However if I do :

I am trying to write a message to a Kafta cluster programmatically (i.e. not in Ensemble or using a Production) using %External.Messaging. I am consistently getting a 'topic not found error' even though I have created the topic on the cluster. I dug into the client I created an when accessing the property KaftaClient.jclient.gateway I get the following output:
