#ObjectScript

InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Documentation.

I need another set of eyes to look at the following. Instead of a Data Lookup table, I wanted to try to lookup a value against a Cache table that I had build. So I thought I could write a function to run a simple SQL query against the Cache Table and return me a %Boolean value back to my routing rule. However today I found that it was not working properly.

Can someone take a look at the following method and verify that I am doing this correct?

index = column name

value = HL7 field that I am passing into the method

Hi,

I have the requirement to dump large result sets into files. I am currently using %SQL.Statement and the result set created by it.

The DisplayFormatted is used to write a CSV. The query I used to test does not contain any filters, it is just a select * from a table with 16 million rows.
The file created is 2GB in size. The issue I have is that it takes 8 hours to create this file.

Portal's category.

Hello,


I’m looking for a way to find out which category of portal a connector belongs to.
I looked at the class ‘Ens.Config.Production’ and ‘Ens.Config.Item’ but without success.


An idea about the ‘ObjectScript’ code to design?

Best Regards.

Hello fellows, I need you wisdom.

In my organization we code in ObjectScript and .int everyday. When I joined nobody knew barely nothing about classes and their use was almost only for storage definition purpose. During my self-learning in caché I discovered the object oriented programming and class developing was possible in caché and started to code in .cls . Being something self-taught, I may have some basic doubts I'd have missed in my documentation readings.

I am writing a Python tools I want to access the %Monitor.System.License properties:

  1. AvailableDist
  2. AvailableLocal
  3. MaxUsedDist
  4. MaxUsedLocal
  5. CurrentUsedDist
  6. CurrentUsedLocal

Initially I want to develop Objectscript to verify access to the properties. But I can not figure the proper syntax.

I first attempted:

set ans = ##class(%Monitor.System.License).AvailableDist

which failed.

I tried another approach:

set ans = ##CLASS(%Monitor.System.License).%GetParameter("AvailableLocal")

Is it a good practice to set the MAXLEN value of %Library.String property type? Will it lead to wasted storage if its not really using it?

For example, I have to store a 5 characters long string into the below str field. Which of the statement is recommended?

Property str As %String;

vs

Property str As %String(MAXLEN="5");

Is there a way to add specific table permissions to a security role programmatically? I'm working on scripting some of the initial setup work when we sell certain add-ons to our software, and I see how I can assign resources to a role and give it a description, but I don't see how I tell it that this role gives the user, for example, SELECT privileges only on the invoices table, or SELECT, INSERT, UPDATE, and DELETE.

I'm wondering how I would go about adding headers to a csv file which has already been created. I am unfamiliar with ObjectScript.

For example if I were to use R, I would simply write..

test <- read.csv("file/path/example/Extract.csv", header=FALSE)
colnames(test) <- c("A","B","C","D","E")

I do not have embedded Python installed either as I would know how to do it in that also.

How could I mirror this in ObjectScript please?

My current create file method:

Hi folks!

How can I change the production setting programmatically?

I have a production that is a solution that uses some api-keys, which are the parameters of Business Operations but of course cannot be hard-coded into the source code.

E.g. here is the example of such a production that runs a connection of Telegram and ChatGPT.

And it can be installed as:

zpm "install telegram-gpt"

But now one needs to setup the key manually before using the production, having the following setting:

I'd like to set up it programmatically so one could install it as:

zpm "install telegram-gpt -D Token=sometoken"

How can I make it work?

REST Documentation Confusion

I had attempted to create a REST Operation before but did not have success. As I am going through the Tutorials and Documentation everything references REST services, but I have a case where I want to create a REST Operation that makes Epic API calls against Interconnect. I have done SOAP operations before and we currently have one in our Production Namespace, but from what I understand SOAP has the wsdl which defines al the structures and etc, where REST does not.

Hi Community,

Can anyone point me to the docs that show how to add automatic class documentation for the arguments used in a method call? I can auto document the class, methods, properties etc. with the "///" but can't figure out how to get the nice argument documentation for the arguments used when calling a method.

Thanks in advance

Hi folks!

I'm building a very simple REST API.

But before testing it via a Web Server what I want to make sure that REST API methods work in principle.

Is it an easy way to "fake" the web-server request and get a result e.g. of the method with signature like that?

ClassMethod GetAllRecords(pRequest As %CSP.Request, pResponse As %CSP.Response) As %Status

e.g. calling it in Terminal?

Currently, we are utilizing batch jobs at the OS level to kick off routines that watch for files. We are trying to convert these processes to be performed by the Task Manager.

The routines have while loops and perform while loops so long as the time parameters are being met.

What's the best way to ensure Task Manager kicks them off after the completion of the shutdown/backup/start process is performed, which we do nightly? I want to ensure that it starts it regardless of the time that we've set.
