When using Related Cubes in InterSystems IRIS BI, cubes must be built in the proper order. The One side must be built before the Many side. This is because during build time for the Many side, it looks up the record on the One side and creates a link. If the referenced record is not found on the One side, a Missing Relationship build error is generated. The One side is going to be the independent side of the relationship, AKA the side of the relationship that is referenced by the Many side or the Dependent cube. For example: Patients contain a reference to their Doctor.

Hello!

I am taking the 'Creating an InterSystems Class Definition' course, and the Exercices asks to open a Terminal from the Management Portal to create and interact with a new object. I didn't found how to acces tot the Terminal from the Management Portal, and the documentation I have seen doesn't help me... 

In some moment I saw a video wich explains how to acces to the terminal, but I can't find it. ¿Can someone explains me how to find the Terminal acces?

Thank you!

Did some quick testing replacing Intersystems.Data.CacheClient.dll with Intersystems.Data.IRISClient.dll and ran against Cache 2018.1 and IRIS 2019.1. Seems to work in both cases. Is it a safe assumption that the IRIS dlls are backward compatible with Cache 2018.1?

Wondering whether it's possible to get %UnitTest to output an arbitrary key-value pair (a new property) into ^UnitTest.results ?

I have an array of table names that I want to iterate over and for each table, get the number of rows.  I was hoping I could do something like:

set tStatement = ##class(%SQL.Statement).%New()
set tSC = tStatement.%Prepare("SELECT COUNT(*) AS ObservedRowCount FROM ?")
$$$ThrowOnError(tSC)
set tTableName = ""
for
{
  set tTableName = $O(tCounterAry(tTableName))
  quit:tTableName=""
   set tResult = tStatement.%Execute(tTableName)
  // ...
}

But that doesn't work:

ERROR #5540: SQLCODE: -1 Message:  IDENTIFIER expected, ?

Some readers of my previous article, Caché eXTreme for .NET - direct access to globals from C#, wondered if you could access information not just from the same instance in which you’re working, but also from another instance on the same computer, or from an instance located on another computer in the same local network. Some theorized, correctly, that this would be possible using the Enterprise Cache Protocol (ECP). In this article I’m going to show how it can be done.

Have you ever needed a math function but could not find what you needed and ended up writing your own? Look no further! ObjectScript-Math is here to solve all your math related function needs.

ObjectScript-Math is an Open Source library for ObjectScript Math functions. It is now available on Open Exchange. This library contains a mix of new functions that are not currently available and functions that are available. The existing functions will be wrapped for use from ObjectScript-Math so that all Math functions can have a central location.

This library will continue to grow, so give it a try and give your feedback!

Don't see what you are looking for? Please feel free to submit requests for additional functions or contribute code yourself!

I'm currently working with a developer to add IRIS/Caché functionality to his HL7 analysis tool that would allow its users to extract messages directly from the Ensemble message store. IRIS for Health Community Edition has been a great aid in debugging this, but I keep banging into the 5 connection license limit with Studio, the Management Portal, an IRIS terminal session and a client database connection using either ODBC or ADO.NET.

I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.

I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:

Class User.HL7.

This series of articles would cover Python Gateway for InterSystems Data Platforms. Execute Python code and more from InterSystems IRIS. This project brings you the power of Python right into your InterSystems IRIS environment:

• Execute arbitrary Python code
• Seamlessly transfer data from InterSystems IRIS into Python
• Build intelligent Interoperability business processes with Python Interoperability Adapter
• Save, examine, modify and restore Python context from InterSystems IRIS

Other articles

The plan for the series so far (subject to change).

What is %SQLRESTRICT

%SQLRESTRICT is a special %FILTER clause for use in MDX queries in InterSystems IRIS Business Intelligence. Since this function begins with %, it means this is a special MDX extension created by InterSystems. It allows users to insert an SQL statement that will be used to restrict the returned records in the MDX Result Set. This SQL statement must return a set of Source Record IDs to limit the results by. Please see the documentation for more information.

Why is this useful?

This is useful because there are often times users want to restrict the results in their MDX Result Set based on information that is not in their cubes. It may be the case that this information may not make sense to be in the cube. Other times this can be useful when there is a large set of values you want to restrict. As mentioned before, this is not a standard MDX function, it was created by InterSystems to handle cases were queries were not performing well or cases that were not easily solved by existing functions.

Hello community!

I have 2 productions A and B on the same IRIS instance sharing one operational database.

I'm looking for a simple and efficient way to send a message from production A to production B.
Any suggestion ? Could it be done through the database only?

And I wish you a happy new year!
Thanks :-)

I generated a REST API from a Swagger document with basic security.

When I send a request to that API, I now get an authentication error 401 always.

I entered a user api and a password and gave it the role %All.

I tried to call the API with the URL

http://solidara.net:52773/csp/solidara/get_components/solidara?username…;

What's am I doing wrong there?

Launching IRIS Using Docker

This brief document will walk through the steps to launch IRIS community edition using Docker on the MAC. For those new to Docker, the first two pages explain how to install Docker, and run some basic commands that will be needed to get the IRIS community edition running. Experienced Docker users can skip directly to page three.

1. Get Docker Desktop for MAC. This can be downloaded at Docker Hub, but one should look at the requirements before downloading it to ensure it works smoothly. The directions and download link are at: https://docs.docker.

Hi Team,

I want to save image/file using inter system iris web api.

I am sending file as Base64 formate  in JSON object to api .and I want to save it at D/Images folder.

please refer below code that i was tried.

Obj.OrganizationLogoBase64--> has base64 value of image

Set decode = $System.Encryption.Base64Decode(Obj.OrganizationLogoBase64)

set file = ##class(%Stream.GlobalBinary).%New()

    do file.Write(decode)

Hi Team, 

I want to read image stored in "D:/temp/test.png"  and then convert it to base64.

Hi Developers,

It's December the 1st! And this means that the Advent of Code 2019 has been started!

And you are very welcome to participate in the ObjectScript contest!

In the previous part of this series, we saw how to reference a web page that will enhance our dashboard experience.  Now we will look into referencing data that is already in our cubes.

In this example, we will be referencing the controller object and we will be extracting data from it. This data will then be displayed as text in our Dashboard. In Part 5, we will show how to incorporate this data into other charting libraries.

Why use this?

The controller object contains data from an MDX result set.

Hi!

I am wondering how I can test that my application can be installed through ZPM before I publish it to Open Exchange. How can I accomplish this?

Hi,

The class %JSON.Adaptor is very convenient,

I wonder if anyone faced the following scenario using it-

Exporting an object, that has a many to many relationship, and getting the details of the related objects.

For example, if we have three classes - Teachers, Students, and an intermediate class TeacherStudent .

The classes extend %JSON.

Hi Developers!

Often we need to use relatively small arrays with constants, static arrays in algorithms, etc where we need to do something with each element of an array. There are several ways to deal with it in ObjectSctipt. 

Previously I used to use globals, locals, PPG for this but not so long time ago figured out that %List is a way too handy.

Indeed, suppose we have an array of months and need to set up and use it in our code.

Hello, Community!

After beta testing the new exam InterSystems IRIS Core Solutions Developer Specialist at Global Summit 2019, the Certification Team of InterSystems Learning Services has performed the necessary calibration and adjustments to release it to our community. It is now ready for purchase and scheduling in InterSystems exam catalog. 

This is InterSystems first certification exam to feature mainly code samples as question topics. To give potential candidates a sample of the exam's content, practice questions have been published to help orient to exam question approaches and content.

It seems that everyone who is moving from Caché to IRIS have noticed this small change among other, more noticeable ones. But have you noticed that temporary globals mapping rules have been changed as well?

Hi All,

I trying to get the DisplayList data of the ValueLIst from Java using Springboot. when I try to get the DislayList data via java code but I'm getting the VALUELIST data. I don't get any idea to get that DisplayList data. Below is the example

Property PetName As %Integer(DISPLAYLIST = ",Cat,Dog,Dove,Parrot", VALUELIST = ",1,2,3,4");

Java Code:

public String PetName;

public List<Pet> getPet() {
        return ser.findAll();
    }

List<Pet> arrayList = getPet();
        for (Patient list : arrayList) {

                 String pet= list.getPet();

                 System.out.

Hello, InterSystems community!

Lately, you have probably heard of the new InterSystems Package Manager  - ZPM. If you're familiar with it or with such package managers as NPM, Dep, pip/PyPI, etc. or just know what is it all about -- this question is for you! The question I want to arise is actually a system design question, or, in other words, "how should ZPM implement it".

In short, ZPM (the new package manager) allows you to install packages/software to your InterSystems product in a very convenient, manageable way.

I've been having a blast with the Advent of Code puzzles this year - though I'll be heading into a busy span of time with family soon and will probably drop off toward the end. (At least, that's what always seems to happen - it's a good thing, though!)

I had a whole plane ride to play around with Day 13 and wanted to share some fun terminal tricks.
