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.
I'm currently looking at a process where we're utilising the Class Ens.StreamContainer, and was looking to do some deletions outside of any purge routines.
Having been burned before, I wanted to make sure that deleting the container also deletes the contents within.
From looking in the class, the %OnDelete ClassMethod appears to be removing an index from a search table and nothing more.
For programmers new to ObjectScript, one question will inevitably arise: “What is the difference between methods and class methods?” A typical answer would be: “A class method applies to a class, but a method applies to an instance of that class.” While that answer is correct, it lacks important information on how these methods di
I was wondering if someone could help me. In the past I have been able to call external Stored Procedures through a SQL Outbound Connection and have them return me the EnsLib.SQL.Snapshot to use within a BPL to extract data.
But this time instead of using a SQL Outbound BO to make the Stored Procedure call, I decided to create a Linked Stored Procedure through the %JDBC_Server to point to the Stored Procedure out on MS SQL.
However, I am struggling to get the code just right to return the Column value from the Linked Stored Procedure.
I have the need to query an external database and write the result set/snapshot to an internal %Persistent [ DdlAllowed ] table that I built. I have built inbound SQL Services before and write them externally to replace SSIS jobs, but how would querying a database via a Service and writing the data to an internal table work?
Can I just take the inbound query structure and write it to the class file of the internal table in a DTL? If so, what would be the Target? Or does this need to be done within a BPL as a Code block?
I have built a REST operation to submit a JSON Request Body, and in the JSON Response Object, I need to pull out certain values like pureID, portalURL, and under the identifiers array the ClassifiedID that has a term."en_US" = "Scopus Author ID"
I have a new project to store information from REST responses into an IRIS database. I’ll need to sync information from at least two dozen separate REST endpoints, which means creating nearly that many ObjectScript classes to store the results from those endpoints.
In this article, I will outline and illustrate the process of implementing ObjectScript within embedded Python. This discussion will also reference other articles related to embedded Python, as well as address questions that have been beneficial to my learning journey.
As you may know, the integration of Python features within IRIS has been possible for quite some time. This article will focus on how to seamlessly incorporate ObjectScript with embedded Python.
Throughout the forum, I find examples of using the method getSegmentByIndex to get the segment as I loop through the HL7 message segments.
Today I spent way too long trying to figure out why I could not modify the segment with this same method. I reached out to my more experienced team and I showed where I got the base code from what I was doing, but I myself could not find the documentation of the method.
I have a business process that adds data to a global variable on receipt of an HL7 message, and a scheduled task that executes a class method defined within the same business process that removes data from the same global variable. With this in mind it makes sense to consider concurrency and therefore make use of the LOCK command.
My first question is whether this is actually necessary?
Everytime I try to send a POST FHIR bundle I'm getting the following response: 404 Not Found. I'm not really sure why, although it works fine with a GET!
This is an example:
Response:
It might be something related to request path but not really sure.
I already mentioned in a Previous post I am trying to build a list from a repeatable field within a HL7 message. I figured out how to build the list by using a context list string variable within the Business Process (BPL) and doing a
I'm sure I've seen this issue reported before, but a search hasn't turned it up.
This appears to happen randomly, but once it starts it doesn't seem to stop ... at least for a while. I attempt to compile a class and compilation fails but produces no error explaining why. Here's an example:
Many programming languages use the try-and-catch construct to handle runtime errors gracefully. If the code within the try block encounters an error, it will throw an exception to the catch block, where the error handling occurs.
The InterSystems platforms have always offered dynamic documentation of the packages and classes in a namespace, a feature known informally as Documatic. But what if you need to publish this class reference information on a website without requiring the site to be connected to an IRIS server containing the actual classes?
Is there documentation that shows the mapping between the management portal components and object script package.class.methods? I am searching on-line documentation but have not been successful. For example, in the management portal SystemOperation > TaskManager > TaskSchedule can map to the method: class(Monitors.Tasks).ListSuspendedTasks().
What would be a similar mapping for SystemOperation > TaskManager > TaskHistory? I initially thought it would be something similar to class(Monitors.Tasks).ListTaskHistory().
