I'm trying to read the response to a long (indefinitely) running HTTP response with Transfer-Encoding: chunked. Ideally I'd be able to read the individual chunks from the response and do something with them as they arrive rather than needing to wait for the response to finish (because it never will) - ultimately I'm thinking to wrap these back up over a WebSocket connection which seems cleaner from an API perspective.

So far it looks like my options are:

• Extend %Net.HttpRequest, override the Read method, and add support for read of individual chunks from an ongoing request (similar to what

InterSystems has corrected a defect that can cause an SQL query to return incorrect results.

The defect exists in the following products and any InterSystems offerings based on them.

Impacted versions are 2021.2, 2022.1.x, 2022.2, and 2022.3:

Hi developers!

What is the way using SQL to list all the tables available in the current database/namespace?

Hi.

I have a query:

SELECT '['||Material->Sifra||'] '||Material->Opis AS Material,
       SUM(MasaBlago) AS MasaBlago
 FROM Tehtanje.Dokument
 WHERE DatumDokumenta BETWEEN '01/01/2023' AND '04/01/2023'
 AND (Material->Sifra %INLIST $LISTFROMSTRING('5,7',','))
 GROUP BY Material
 ORDER BY %EXACT Material

The query returns all rows where Material->Sifra is 5 or 7. That's OK.

If I want to get all rows where Material->Sifra is NOT 5 or 7 I use query:

SELECT '['||Material->Sifra||'] '||Material->Opis AS Material,
       SUM(MasaBlago) AS MasaBlago
 FROM Tehtanje.Dokument
 WHERE DatumDokumenta BETWEEN '

Most of the databases with SQL access offers the DATE_TRUNC function or analogs. This helps to easily truncate a date by any part while keeping the DateTime in a valid format

In some testing scenarios, I need to clone the database. While I use only SQL access.

I need all data to be cloned, not mapped from the original database, and a separate database to be accessed.

Is there any way to do so?

Something like

CREATEDATABASE [Databasetocreate]
WITHTEMPLATE [Databaseto copy]

When using %JSONImport it seems to only report a single error, is there a way to report all the errors with out having to do multiple requests?

I've been working for some days in the connectivity between NodeJS client applications and IRIS as server using web sockets.

You can get all the information in relation to the web socket connections using IRIS as a client or as a server from this URL: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

For this example we are going to configure an asynchronous server, that would be really usefull to create a subscription manager for our productions.

During a migration from a rather old Caché Version (2016.1) to IRIS
I met the problem to migrate Streams.
The difference in the storage Global is minimal
It's not a big effort to do it manually for a few streams.
But for some thousand streams I hope there is a tool already available.
But where?

Our ERP solution runs on different sql databases (such as ms sql and posgre). We are using the same code for all plattforms, doing database-specific changes in the db driver for each type of database.

There is one function in our program, where the user can store long text to discribe something, which is used in print and web. This text is treated/stored as html and can include pictures. The pictures in the html are stored base64 coded inside the html and the html is stored as text in a column. In other database systems, this is treated as TEXT or BLOB, and workings just fine.

But with IRIS,

First of all, what is data anonymization?

According to Wikipedia:

Data anonymization is a type of information sanitization whose intent is privacy protection. It is the process of removing personally identifiable information from data sets, so that the people whom the data describe remain anonymous.

In other words, the data anonymization is a process that retains the data but keeps the source anonymous. Depending on the adopted anonymization technique the data is redacted, masked or substituted.

And that is the purpose of iris-Disguise, to provide a set of anonymization tools.

You can use i

Is anyone like me, and felt really jealous that they didn't have enough points to acquire the IRIS-based Raspberry Pi system when it was offered? Do you have a spare Raspberry Pi 4 handy? If so, I'll walk you through setting up Docker and IRIS on your Raspberry Pi so you can have the smallest IRIS computer in town!

Things you'll need:

Raspberry Pi 4 (at least 4G RAM, but I have several with 8G so that's what I used. 2G RAM *might* work, but there might be a lot of swap file activity which would slow down the process considerably)
MicroSD card (at least 16G, but I'd recommend 32G or more)

WIN SQL is the normal editor used by most of the users .But we can't download large amount of data using winsql . So I have written a tutorial how to connect with a new Java based editor called Squirrel SQL which can easily download or export data in excel or any other formats. Also I included a Java JCBC connection program to connect with the IRIS database especially a mirroring/failover server.

with _engine.connect() as conn:

    print(rs.all())

or with native api

from sqlalchemy import create_engine, text,types,engine

# set URL for SQLAlchemy
url = engine.url.URL.create('iris', username='SuperUser', password='SYS', host='localhost', port=33782, database='FHIRSERVER')

_engine = create_engine(url)

InterSystems FAQ rubric

You can programmatically retrieve routine dates and sizes using the RoutineList query of the %Library.Routine (or just %Routine) class.

The RoutineList query has an argument, and the routine name to be searched can be specified by prefix match or middle match. (For wildcards, specify * or ?)

In the example below, *.MAC is specified as an argument.

SET tStatement =  ##class(%SQL.Statement).%New()
 DO tStatement.%PrepareClassQuery("%Routine" , "RoutineList") 
 SET rs = tStatement.%Execute("*.MAC",,0) 
 DO rs.%Display() 

In addition to the routine list, you can

Hi Developers,

See how the Production Extension framework (PEX) allows you to build custom interoperability components in .NET or Java without first learning ObjectScript.

With PEX, you can code in a familiar language and take advantage of established code libraries to add components to a production.

IRIS configurations and user accounts contain various data elements that need to be tracked, and many people struggle to copy or sync those system configurations and user accounts between IRIS instances. So how can this process be simplified?

In software engineering, CI/CD or CICD is the set of combined practices of continuous integration (CI) and (more often) continuous delivery or (less often) continuous deployment (CD). Can CI/CD eliminate all our struggles?

Hi all!

In a project we needed to define topics to publish messages and register different subscribers which will receive those messages asynchronously. We also needed it to be as simple as possible and that we could use it on InterSystems IRIS directly.

As an experiment, I'm sharing this iris-pubsub open exchange example.

This is built on top of InterSystems IRIS interoperability features, it needs a running production.

The first time we need to define how many partitions we want to dedicate to handle messages. The more partitions you add, the more capacity to handle messages.

Hi Developers,

Often we create and edit InterSystems IRIS Interoperability solutions via a set of UI tools that is provided with IRIS. But it is sometimes difficult to setup the development environment to handle changes we make in the UI to source control.  

This video illustrates how git-source-control helps with source control Interoperability components while changing it in the UI.

If you are seeing this error during import: ERROR #6301 Line: 2 Offset: 118 This does not appear to be a Cache exported file, unable to import.

This error is caused by exporting from InterSystems IRIS and trying to import into Caché. If you plan on exporting from IRIS to Caché, you can use the following qualifier to export your classes so that Caché does not throw an error on import:

w $SYSTEM.OBJ.Export(<items>,<filename>,"/exportversion=cache2018.1")

Please see the Documentation for more information about this Export Qualifier

If you are using Python, you can use the built-in venv module to create a virtual environment. This module is the recommended way to create and manage virtual environments.

A virtual environment is a tool that helps to keep dependencies required by different projects separate by creating isolated python virtual environments for them. It solves the “Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keeps your global site-packages directory clean and manageable.

So if like me you work a lot with Python, you can use the venv module to create a virtual environment for your project. This will allow you to install packages without affecting the global Python installation.

You will find here two neat alias to create and activate a virtual environment.

Python aliases

alias venv="python3 -m venv .venv; source .venv/bin/activate"
alias irisvenv="python3 -m venv .venv; source .venv/bin/activate; pip install https://github.com/grongierisc/iris-embedded-python-wrapper/releases/download/v0.0.3/iris-0.0.3-py3-none-any.whl"

SSH framework is a relatively representative framework of Java, which was popular many years ago. There are Struts+Spring+hibernate and Spring MVC+Spring+hibernate. Of course, I used the second one in college. If I can connect IRIS to Hibernate as a library, does it also mean that IRIS can be developed using SSH framework in theory?

What is Query

Query is a method for finding data that meets the conditions and presenting the results as a data set.

Type of Query

• SQL Query，Using %SQLQuery and SQL SELECT.
• Custom Query，Using Class %Query and custom logic to generate result.

Note: Before we talk about the general Query solution, let's first understand the basics of Query to help understand the implementation principles. If you already know the basic use of Query, please skip this section and go straight to "Challenges".

Visual Studio Code (VSCode) is the most popular code editor on the market. It was created by Microsoft and distributed as a free IDE. VSCode supports dozens of programming languages, including ObjectScript, Until 2018, Atelier (based on Eclipse). It was considered as one of the main options to develop InterSystems products. However, in December 2018, when the InterSystems Developer Community launched support for VSCode, a relevant portion of InterSystems professionals started actually using this editor and have been doing it ever since, especially the developers working with new technologies (
