Hello,

I am interested about reading the source code of the primitives of the system.  For example, I want to see how WRITE is implemented.

Can you help me to get a reflexive interrogation of the system ?

Kind regards,

Alin C Soare.

I was trying to interact through IRIS terminal by giving user id and password from command-prompt, but iris terminal command is not recognizing. Please suggest how i can interact with iris terminal here. 

iris terminal <instance name> -U <user id> -P <password> not working

Please note i am new to IRIS. 

Can any one tell me the difference between %KillExtent and %DeleteExtent with example

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.

To avoid a very long article and make it more accessible, I am going to divide it into 3.

i want to update some values in tsysparameters table through powershell. how to write the script.

Finally and with a little delay, we conclude this series of articles about our Workflow Engine by showing an example of the connection that we could make from a mobile application.

In the previous article we showed the example that we were going to discuss, an application that allows detailed control of a chronic pathology such as hypertension for both the patient and their associated doctor.

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

GMMHTIE 2d1>do ##class(temp.Nothing).What()
 
DO ##class(temp.Nothing).What()
^
<COMMAND>^temp.Nothing.

In a customer project I was asked how you can keep track of database changes: Who changed what at which date and time. Goal was to track insert, update and delete for both SQL and object access.

This is the table that I created to keep the Change Log:

/// Changelog, keep track of changes to any table
Class ChangeLog.DB.ChangeLog Extends (%Persistent, %JSON.

Background

In InterSystems IRIS versions >=2021.2 we can use the accompanying irispython binary to directly write python code on top of our IRIS instances. This lets us use python packages, call methods, make SQL queries, and do nearly anything in Objectscript but pythonic.

For example, below I check if a namespace is present:

#!/usr/irissys/bin/irispython
import iris
# call arbitrary class methods
result = iris.cls('%SYS.Namespace').Exists('USER')
if result == 1:
    print(f"Namespace USER is present")

But, what if my method in IRIS has special parameters such as Output and ByRef parameters?

Hello Everyone,

The Certification Team of InterSystems Learning Services is developing an InterSystems ObjectScript Specialist certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.  Please note that this is one of two exams being developed to replace our InterSystems IRIS Core Solutions Developer exam. You can find more details about our InterSystems IRIS Developer Professional exam here.

How do I provide my input? Complete our Job Task Analysis (JTA) survey!

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.

Detailed descriptions for syntax errors

In the past, all syntax errors were reported simply as "Syntax error.

If you want to get the initial and last day of a month, I have a ClassMethod to you (version 2, fixed an error found by Eduard):

ClassMethod GetMonthPeriods(InitialYear As %Integer, EndYear As %Integer) As %Status
{
    set sc = $$$OK
    set result = []
    For CurrentYear = InitialYear:1:EndYear {
        For CurrentMonth = 1:1:12 {
            set item = {}
            If CurrentMonth < 10 {
                Set CurrentMonthStr = "0"_CurrentMonth
            } Else {
                Set CurrentMonthStr = ""_CurrentMonth
            }
            Set item.

Hi,

We are developing a .NET6 application using Iris database. We would like to use ORM for easier code maintenance. 

I saw a doc about Entity Framework: https://docs.intersystems.com/iris20231/csp/docbook/DocBook.UI.Page.cls?KEY=BNET_eframe, but even it's newest Iris version, the Entity Framework is very old .NET Framework (2013) and not supported by Microsoft anymore. Are there any plans to support Entity Framework Core?

Hi All,

I am working on SQL based KPI in IRIS BI. I want to remove below highlighted search text box in "auto" filter type.

We cannot use other type like only dropdown etc. Is there a way we can do this ? 

One way I can see is writing own control instead of using default control but I am not aware how to do this. I didn't find any sample code for this. 

Is there any sample code available for writing custom control which I can refer.

Please assist

Hi everybody, I am trying to connect with an IRIS database where to retrieve data and import them to SQL server but the access gets denied. I would appreciate your help, Thank you, Jeb

I have following information:

Data Source Name --> I use it as the server name

Host(IP Address)

Port

Namespace --> I could use it in my script

import pyodbc

connection_string = ( "DRIVER={InterSystems IRIS ODBC35};" "SERVER=;" "PORT=;" "DATABASE=________;" "TrustServerCertificate=yes;" )

try: conn = pyodbc.connect(connection_string) print("Connection successful") except pyodbc.Error as ex: sqlstate = ex.

Data Analysis

This is the sequel to Data Collection. If you have not had a chance to go through and install that you should first do that.

What is provided here is the analysis for the collection of that data that was collected earlier.

In much the same way as was done in that repository you will need to import the xml that makes up this repository.

Starting at the topmost level there is a task:

InvestigateInfoTask

This task will allow us to set parameters that we will be monitoring. They are as follows:

GrowthPercentageWarning: What percentage growth is 'acceptable' for a global to grow.

Graphical Display of Tables

Here we will document how you can get the results of your Data Collection to be displayed graphically. The output of your project will look like this:

Note that I am working on a local machine. If you are doing this on a server then be aware to use the correct IP address.

First, we will import the three classes from the that we are going to need (note that we will edit them later):

You can take the xml and import it to your system.

The spec will actually create the dispatch class and implementation template.

Hi, 

I almost managed to connect myself from nodejs to IRIS via intersystems-iris-native, but the connection failed. 

> const irisnative = require('./intersystems-iris-native')
> irisnative
{
  createConnection: [Function (anonymous)],
  Connection: [Function: Connection],
  Iris: [Function: Iris],
  Iterator: [Function: Iterator],
  IRISList: [Function: IRISList]
}
.....
>     var connection = irisnative.createConnection({
...     host: ip,
...     port: port,
...     ns: namespace,
...     user: username,
...

Columnar storage is one of the newer offers provided by InterSystems IRIS. Unlike traditional row-based storage, it optimizes query processing by storing data in columns rather than rows, enabling faster access and retrieval of relevant information.

A couple of articles have been written on when it should be used to give a system the biggest boost, how to create tables like that using SQL

CREATE TABLE table (column1 type1, column2 type2, column3 type3) WITH STORAGETYPE = COLUMNAR  -- ex 1
CREATE TABLE table (column1 type1, column2 type2, column3 type3 WITH STORAGETYPE = COLUMNAR)  -- ex 2

and even the performance tests.

As we all know, InterSystems IRIS is a multi-model DBMS and it gives seamless access to the same data using relational and object access. So the former is covered in other articles, but what about the latter?

Translated from the Spanish Community Article Contest.

Following the latest programming contest on OEX I had some surprising observation.
There were almost exclusive applications based on AI in combination with pre-cooked Py modules.
But digging deeper, all examples used the same technical pieces of IRIS.

Seen from point of view of IRIS it was pretty much the same whether searching for text
or searching for images or other pattern.  It ended in almost exchangeable methods.

This reminds me my private situation at home.

Hi all! 

How can I get the ODBC drivers for IRIS 2024.1 if I am only using IRIS 2024.1 Community Edition? 
This page gives you the information: "The official location for customers to download the latest released and fully supported InterSystems IRIS driver packages is the WRC download site." My first thought on this is: Why does Intersystems make it so difficult for users to use their database? Why is the ‘official’ driver package hidden behind a login wall? Shouldn't Intersystems be happy if someone wants to work with their database, wants to connect?

Hi there,

I am interested to execute ObjectScript commands from external language.  I saw that IRIS provides the irisnative library for this.

I am using Windows and 8-bit IRIS server (due to compatibility with old software I need to use 8-bit instead of Unicode).

I tried to execute irisnative for Javascript and for python, without success, as I explained in my previous questions.

I would like to ask you whether Intersystems provides an API to execute commands from external scripts (the same as Visual Studio Code does when I execute commands like "Import and Compile", etc.).

Hi Community
In this article, I will introduce my application irisChatGPT which is built on LangChain Framework.
First of all, let us have a brief overview of the framework.

The entire world is talking about ChatGPT and how Large Language Models(LLMs) have become so powerful and has been performing beyond expectations, giving human-like conversations. This is just the beginning of how this can be applied to every enterprise and every domain! 

Beginning with the release of InterSystems IRIS® data platform 2022.3, InterSystems corrected the license enforcement mechanism to include REST and SOAP requests. Due to this change, environments with non-core-based licenses that use REST or SOAP may experience greater license utilization after upgrading. To determine if this advisory applies to your InterSystems license, follow the instructions in the FAQ linked below.

This table summarizes the enforcement:

To disable the timeout, set the query timeout to disabled in the DSN settings:

Windows Control Panel > Administrative Tools > Data Sources (ODBC) > System DSN configuration

If you check Disable query timeout, the timeout will be disabled.

If you want to change it on the application side, you can set it at the ODBC API level.

Set the SQL_ATTR_QUERY_TIMEOUT attribute when calling the ODBC SQLSetStmtAttr function before connecting to the data source.
