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)

Hello,

I would like to schedule the Database Compact and Freespace methods as legacy tasks.

Has anyone implemented this yet?
Is this even possible? 

The request for this is due to the fact that we have 3 interfaces in a namespace whose messages are deleted after 7 days. All other messages in this namespace should be kept for one year.
This leads to a certain fragmentation. Furthermore, the messages to be deleted are relatively large (MDM^T02 > 32MB), which in turn leads to a fast growth of the database size. 

How would you solve this problem?

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 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.

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?KEY=...

I have been playing around with the Management Portal deployment tool, which involves:
Ensemble > Manage > Deployment Changes > Deploy and
Production Settings > Actions > Export
Production Settings > Actions > Re-Export

Everything was going fine , until I came across this:

Is Cache the preferred database source for extracting data elements for use in Health Share Patient Index or is there a significant benefit in sourcing data from a warehouse, data mart, or MV? I realize that could be a loaded question with 100 other questions that may follow, however, if there is a known advantage to extracting data from a particular data storage type, the answer may highlight that point.

Let's say I have this simple script  file try.script

write 1
write 0

I can execute it in a terminal (csession) by calling:

csession cache < try.script

And I get the following output:

%SYS>
1
%SYS>
0

However I want to use a try catch block in my script:

try {
write 1/0
catch {}
halt

But as script is executed line by line, it's interpreted like this:

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 have inherited a web-based database application and I'm having a hard time understanding the sequence of events when CSP pages are opened.  I have very limited web development experience.

Can anyone recommend a good resource for explaining this?  I have already gone through the Cache Cinema tutorial and the Cache CSP documentation.

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 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.

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.

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”

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?
