InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Question Eduard Lebedyuk · Apr 1, 2020

During runtime I build an object which is essentially a wrapper over in-memory table:

col1 ... colN
val11 ... valN1
val12 ... valN2

I want to use this object as a part of INSERT or UPDATE queries, based on a value of some column (the main use case one of the columns is an ID value)

What's the best way to expose the object to SQL?

I have complete control over object class, so if I need  to add something (or even change runtime internals), it's no problem.

Object may have different columns depending on runtime situation, but during one query execution the fields are

Hi Community,

We're pleased to invite you to join the upcoming InterSystems IRIS 2020.1 Tech Talk: API-First Development on May 5 at 10:00 AM EDT!

In this week's InterSystems IRIS 2020.1 Tech Talk, we'll discuss API-first development and how InterSystems is embracing this industry trend with our API Manager, and specifically with our FHIR offerings. First, we'll talk about InterSystems API Manager. This tool controls your web-based API traffic in a single location. You can throttle throughput, configure payload sizes and whitelist/blacklist IPs, among many other features.

FHIR stands for Fast Healthcare Interoperability Resources. Release 4 brings this HL7 standard to maturity, and the FHIR R4 support in InterSystems IRIS for HealthTM is big. You'll learn how to work with FHIR data in InterSystems IRIS, and see our developer portal in action, where you can access FHIR resources using the OpenAPI specification.

Question Max Abrahams · Apr 27, 2020

i've noticed a strange bug in the 'problem highlighting' of VSCODE and i wasn't sure if this is a problem with the internal library definitions of iris, or with the plug-in itself.

The first line is the correct macro call, but the second one is the one throwing the error. (preprocess vs prepOrocess)

How is this syntax checker's list of strings compiled?

I enjoy the challenge of being in a contest.Currently I participate in InterSystems IRIS with REST API Programming Contest.My idea for this contest was to create an app to help me keep track of tasks for my Status Reports.I started with the template provided by Evgeny Shvarov.I created a persistent class for Tasks and a REST Dispatch class.I defined my URL map and I even figured out how to test my REST app using Postman.I felt proud of myself for a little while.

When I describe InterSystems IRIS to more technically-minded people, I always start with how it is a multimodel DBMS at its core.

In my opinion that is its main advantage (on the DBMS side). And the data is stored only once. You just choose the access API you want to use.

  • You want some sort of summary for your data? Use SQL!
  • Do you want to work extensively with one record? Use objects!
  • Want to access or set one value and you know the key? Use globals!

On first blush it's a nice story - short and concise and it gets the message across, but when people really start working with InterSystems IRIS

Simple problem:

  1. I leave a long-running command in terminal
  2. Switch to another task(s)
  3. Remember that I need to check on my command after a few hours

Is there any way to force terminal to the foreground after current command ends?

This is Windows with cterm/iristerm although Putty/Kitty solution would also be nice.

One of the things I want from VSCode is to have a familiar Studio look.

Thankfully VSCode is easily customizable so you can choose any color for any element.

Here's what I got so far:

To get the same look add to your settings.json:

"workbench.colorTheme": "Default Light+",
"editor.tokenColorCustomizations":{
    "textMateRules": [
        {
            "scope": "entity.other.attribute-name.objectscript_class",
            "settings": {
                "foreground": "#000000"
            }
        },
        {
            "scope": "string.quoted.double.objectscript",

Hi!

I believe the simplest is (to work with csv delimited by ";"):


set file = ##class(%File).%New( "data.csv" )
    set sc = file.Open( "R" ) 
    if $$$ISERR(sc) quit    ; or do smth

    while 'file.AtEnd {
        set str=file.ReadLine() 
        for i=1:1:$length( str, ";" ) {
            set id=$piece( str, ";" ,i ) 
            write !, id  // or do smth
        }
    }
    do file.Close()

Possible options:

different variants of error handling with sc code.

Embrace while loop into try/catch block.

And what's yours?

Download  MX  into folder  C:/mx   (if Windows)

Create the REST application MX in IRIS namespace USER:

  • USER> do ^%REST …………
  • USER> do $System.OBJ.ImportDir(“c:/mx”,”vmx.ro”,”ck”,,1)
  • USER> do $System.OBJ.ImportDir("c:/mx","rest.xml","ck",,1)

Prepare excel sheet - place on it mx-formulas and mumps-commands:

To connect excel correctly, you must first specify the server address and port in MX_CONFI.xlsb sheet 'connections'. Port see in ^|"%SYS"|%SYS("WebServer","Port").

Run MX.XLSB. Commands written on sheet created a test global on the server and the interface buttons.

This is the first in a pair of articles on SQL indices.

Part 1 - Know your indices

What is an index, anyway?

Picture the last time you went to a library. Typically they have books sorted by subject matter (and then author and title), and each shelf has an end-plate with a code describing the subject of its books. If you wanted to collect books of a certain subject, instead of walking across every aisle and reading the inside cover of every book, you could head straight for the bookshelf labelled with your desired subject matter and choose your books.

A SQL index has the same general function:

Question Edrian Golob · Jun 4, 2019

Hello Guys,

Can someone help me?

I'm triggering a Rest Services, my JSON is a String variable(Request.JSON), when I pass it on EntityBody.Write, WS returns me the 403 error.
When I pass Obj = {} it responds by saying that no Data has been sent.
So, my problem is to set the "Obj" with the String variable, I should convert it, correct?But how do I do this?My JSON is all in this variable.

MyCode:

        Set Dados = ##class(%Net.HttpRequest).%New(),
            Dados.Authorization = pBearer _ Request.Token,
            Dados.ContentType = "application/json"
 
        $$$TRACE(Dados.Authorization)

Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!

Question Rubens Silva · Apr 15, 2020

Hello,

Recently I have been required to work with a method called ExportToStream.

The situation asks me to export a UTF-8-encoded JSON as a XML to be imported on old releases. Here's how I attempted to fulfill this request:

do $System.OBJ.ExportToStream("path/to/my/json/file.json", .stream,,,"UTF8")

The file is indeed encoded as UTF-8 and although the XML header denotes that it has been exported as UTF8:

<?xml version="1.0" encoding="UTF8"?>

The body content seems to differ:

"text": "Condição de pagamento sujeito a análise de crédito: "

I will say it again, the original file is encoded
