I have a list

set list=$lb(1,$c(0),2)

How do I replace $c(0) with an empty element?

My list should look like this:

set list=$lb(1,,2)

I tried using $list but it either replaces the element with an empty string:

set $list(list,2)=""
zw list

Resulting in:

list=$lb(1,"",2)

Or removes the element altogether:

set $list(list,2,2)=""
zw list

Resulting in:

list=$lb(1,2)

Hey folks,

I am new to IRIS and cloud platforms. I've done the InterSystems IRIS Experience on the learning site and read a lot of the online documentation. What I am unable to figure out is which type of package or option you will use on the cloud provider.

AWS for example, has AWS EC2, Elastic Beanstalk and some other products geared towards Docker containers.
Azure has Kubernetes and some other options.

Is IRIS and Docker deployed using the "Docker" products of the cloud providers, or should one get VM's on which CentOS is installed and Docker on top of that?

I have a web application and one of the CSP pages contains the following snippets:

<script language='javascript'>
function SubmitForm(pid,sid) {
//code to process form

alert ("study saved");

self.document.location="newpage.csp";

}

<form name="Studyform"  method="post" onsubmit='return SubmitForm(#(SubjObj.%Id())#,#(StudyObj.%Id())#);' >
<!-- form contents -->

The form is correctly processed, the object is saved, and the alert appears, but the new page does not get loaded and I cannot figure out why.

Any suggestions?

csession can be called with a variety of arguments:

• tag+offset^routine
• tag^routine([parameter-list])
• ##CLASS(package.class).method([parameter-list])

Is there a way to graphically edit BPL processes, or do we still need to use Studio for doing that? 

Looking at the documentation, it appear there should be an Atelier BPL editor option available under Open With, but all I have is Atelier Class, HTML, INT, and MAC editors. 

There is a BPL editor in the list, but it throws a "Bad editor input" error when trying to open the class file. 

I'm running version 1.0.263 that was installed from the WRC distribution of 1.0.262 and then updated.  The only other plugins installed are the Eclipse XML Editors.

Hi all. Today we are going to use k-means algorithm on the Iris Dataset.

Note: I have done the following on Ubuntu 18.04, Apache Zeppelin 0.8.0, python 3.6.5.

Introduction

K-Means is one of the simplest unsupervised learning algorithms that solves the clustering problem. It groups all the objects in such a way that objects in the same group (group is a cluster) are more similar (in some sense) to each other than to those in other groups. For example, assume you have an image with a red ball on the green grass. K-Means will split all pixels into two clusters.

Hello guys,

Based on this article (others as well, but this is the relevant one): http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?

Hi, 
I have general question regarding the InterSystems Platform.
Which features does the platform have, that the other similar platforms doesn't have? 

Hi all. When I try to do this in Apache Zeppelin:

  This error appears:

My jdbc interpreter:

Hi everyone,

I am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)

So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.

I'm trying to add an Operation to store DICOM files but each time I add a Operation using the class EnsLib.DICOM.Operation.TCP it reverts into Services and I cannot work out why this is happening. I've tried following the guide online (link at the bottom) but the Operation still reverts to a Service.

Any pointers would be appreciated,

Thank you.

I have a service that takes a file and pass it through to the production .While I am passing the file through I get the file stream and set it to a variable within my message and the variable is of type %Ens.StreamContainer. But after all processing and I need to write out my file to a pdf format The file gets written but is a corrupt file since I can not read it I have tried this with asimple pass through everything is fine .But here I do not know what I am doing wrong here is the operation code

Hello,

I need to add a new property ("Injection") to an existing database.  The existing database contains, in part:

An "ImageStudy" which contains one or more "ImageFiles"  defined as follows:

Class PET.ImageStudy Extends (%Persistent) 
{
Relationship ImageFiles as PET.ImageFile [cardinality=children,inverse=Study]
...
}
Class PET.ImageFile Extends (%Persistent)
Relationship Study as PET.

I have this local, containing a list of books of arbitrary length:

set books=2
set books(1, "author") = "Alice"
set books(1, "title") = "Hello"
set books(1, "pages") = "123"
set books(2, "author") = "Bob"
set books(2, "title") = "World"
set books(2, "pages") = "456"

And I want to generate this PDF (there could be more than two tables), each book is a separate table:

The header is always the same (Author, Title, Page) but the number of tables would be different.

ZEN reports sounds relevant, but I'm not sure how to pass data from local there and how to draw a separate table for each result.

Hi,

While accessing Trakcare in IE 11 i am getting error:

The Trakcare Layout Editor is not functioning.Please check your browser security setting for scripts and ActiveX controls.You must have ensemble installed locally to use this application.

Hello,

I need to access the value of a setting I created (ex: name_BO) within the logic of my BP.

Property name_BO As %String(MAXLEN = "");

/// Additional Settings 
Parameter SETTINGS = "name_BO:Basic:selector?context={Ens.ContextSearch/ProductionItems?targets=1&productionName=@productionId}";

But the class is common and the production item names will change.

Example -> Class name: My.BP.Common

Items in the production:

Item 1:

• name: My.BP.AA
• use the class My.BP.Common
• value of setting name_BO : My.BO.AA

Item 2:

• name: My.BP.BB 
• use the class My.BP.Common
• value of setting name_BO : My.BO.BB

Where My.

Hello,

I want to know if there is any possible way to use the same query for different ODBC  schemas.

Thanks.

If you're using Firefox, you probably know that there are search engine addons that allow us to use website search directly. Now, docs.intersystems.com is also available as a search engine here. Here's how it looks:

Has anyone used ClearRuntimeAppData,  I am using the EnsLib.SQL.InboundAdapter and pulls the SQL query fine, but if the service needs to keep pulling the same rows the next time the service is started but it will not, due to the parameter “key Field Name”

Hi Community,

Is there any way to integrate or access the data from cloud Integration tool called SnapLogic.

Does InterSystems support any integration? Or can you suggest any sandbox available for FHIR to download and access the data.

Thanks

The code I'm researching loosely follows this flow:

1. My first callback
2. Black box
3. My second callback

I can modify 1 and 3 no problem but modifying 2 is difficult.

However I think that step 2 has some optimization problems, namely:

• instantiates lots of objects
• throws/catches lots of exceptions (not logged)

Is there a way to count these two metrics?

    WHERE ClientIPAddress = :IP)
    While Rset.Next() 
    {

Hi,

Is it possible to call a REST service from a business operation in Cache? Does anyone have a sample for me to take a look at.

Note:

I am new to Cache, just started learning:)

Sometimes, we need to copy part of the properties of an object into a different one. 
The simplest thing would be to do the following:

Set obj1.FirstName = obj2.FirstName

Set obj1.SecondName = obj2.SecondName

What happens if the object contains a large number of properties? or we just want to extract an important group of data, and complement the information in another object?

Having the following classes:

Class Kurro.PersonalInfo Extends %Library.

I am using the EnsLib.RecordMap.Operation.BatchFileOperation to write a batch to a file but for some reason this has been working fine as of yesterday I had a problem with the cache databases filling up running out of memory so had to compact my database and gain space now when I run the operation I get the above error  .Of course in my batch table there is no batch record with ID 1.The message is passed with the correct header information but still get this error any suggestions why?
