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 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?
I'm trying to project a series of objects and nested objects to XML, and I'm having difficulties getting the XML representation exactly the way I need it to be. Here's what I'm working with, nothing complicated:
Is there a programmatic way (in ObjectScript) to determine if a string is an SQL reserved word (aside from using embedded SQL to try to name a property with that string and look for the error :-))?
The goal is to get data (from half a thousand to 3-4 thousands lines) from DB, calculate standart deviation then use it as logical condition in analyzer.
For example IF std > custom_value = show_the_result ELSE null
There is a STDDEV(MDX) method used in Analyzer but it is a measure and it can not be used as logical condition (correct me if i am wrong)
I'm attempting to build a fairly complicated object graph, with nested objects and collections, in order to create a FHIR bundle.
In its most basic form there is a <bundle></bundle> element that represents the root, and there can be a number of nested <entry></entry> child elements.
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.
