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?

Hi ,

I receive xml as incoming request , I convert that into HL7 in my business process class as below

Set tSC = $CLASSMETHOD("myDTL","Transform", .pRequest,.dtlRes)

then , I am sending the dtlRes which is a HL7 message to a router "TEST_ROUTER" 

in the router , I am checking for HL7.{MSH:9.2} , where I am getting below error :

Terminating BP TEST_ROUTER # due to error: ERROR <Ens>ErrException: <PROPERTY DOES NOT EXIST>zevaluateRuleDefinition+15^TEST.SampleRule.1 *HL7,EnsLib.MsgRouter.RoutingEngine -- logged as '-' number - @' set tTempVars("test")=(pContext.HL7.GetValueAt("MSH:9.

Pandas is not just a popular software library. It is a cornerstone in the Python data analysis landscape. Renowned for its simplicity and power, it offers a variety of data structures and functions that are instrumental in transforming the complexity of data preparation and analysis into a more manageable form. It is particularly relevant in such specialized environments as ObjectScript for Key Performance Indicators (KPIs) and reporting, especially within the framework of the InterSystems IRIS platform, a leading data management and analysis solution.

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.

Hi Guys,

This is more of a Javascript question but just in case would have an idea.

basically I'm calling the below JavaScript function from a classMethod to add Options to an html  <Select> tag (Dropdown) and after adding all options I would like to set a specific value or index to be selected, its working and actually the required option is selected but not showing as selected in the dropdown box.

After upgrading we had 2 major problems with the new version:

- Resending messages adds blank lines.
Because we have many HL7 processes, we regulary have to resend messages if there is an outage of a server we connect with.

- IIS recycling causes webgateway connection problems, after change from PWS to IIS.
At unexpected times a connection can no longer be made.
The strange thing is that it does not occur with every recycle of the application pool.
Setting the password again in csp.ini usually works, but not always, which is of course a major problem.

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 Community,

My old code:

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 guys,

How can call a clientMethod, Method or classMethod from a html component?

I've this hyperlink acting as a button in  a zen page and onclick I've tried the below which is actually executing the function but failing to call the classMethod line, and is there a way to just call clientMethod instead of javascript ? 

   <td><a id="btnLast" data-role="button" onclick="getWOs();" href="MyOrders.WO.cls">Last </a></td>
 

ClassMethod retGetWO(wo)
{
Set (WO,Note,Desc,out)=""
if MtcId'=""
{
&SQL(Select  Wo into :WO From Purchace.Order Where id=:wo)
}
I WO'="" s %session.

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

Anyone here know if the Implementation Partner program is still open, and if so, is there anyone we can contact to get more details? I've tried reaching out via the form on the website, I've called and left a message, and then I called and talked to someone a few weeks ago who said they would "forward my info over", but we still haven't heard back from anyone. We just want to get more info on what it entails, but can't seem to get in touch with anybody to talk about it. 

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.

I receive dateTime in this format - yyyy-mm-ddThh:mm:ss+01:00

for ex : 2024-05-31T17:33:08+01:00
I wanted it to convert to yyyymmddhhmmss

desired output = 20240531173308

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.

In our previous article, we have explored the most common Kubernetes components:

• We started with the pods and the services we needed to communicate with each other.
• Then, we examined the  Ingress component used to Route traffic into the cluster.
• We also skimmed through an external configuration using ConfigMaps and Secrets.
• Afterward, we analyzed Data persistence with the help of Volumes.
• Finally, we took a quick look at pod blueprints with such replicating mechanisms as Deployments and StatefulSets (the latter is employed specifically for such stateful applications as databases).

In this article, we will explore Kubernetes architecture and configuration.
