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 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.
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:
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)
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 :-))?
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?
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.
As the title suggests, I would like to programmatically export each HL7 schema category as XML, either as a stream object or to a file. How would I go about doing this?
i am trying to embed a dynamic SQL into Objectscript code , but the %NEXT() will return 0 , however when i copy the same query and run it in the SQL bit it will give me the result i want the code :
As the title suggests, I would like to programmatically export each individual data lookup table as XML, either as a stream object or to a file. How would I go about doing this?
I purchased an HP LaserJet M101-M106 printer, and I'm trying to print via the Windows cache device, but I can't get it to work. I can send it, but it doesn't print. Physical device name: |PRN|HP LaserJet M101-M106 Type: Other Subtype: P-DEC Open Parameters: “W”
Could someone help me with what might be happening?
Hello, I try to develop a REST interface where I need to interact with legacy MUMPS routines. How can I pass in input to a Read without modifying the legacy code?
I think in linux I can execute command < inputfile to read from file, but how does it work in ObjectScript?
I have a theory that I could use an HL7 Data Transformer in a rule without specifying a specific DocType. I want to use the same DTL for a variety of different DocTypes. Here is my very simplistic DTL so far:
We have a background job that keeps an eye on our ongoing CSP sessions, counts licenses used and some other tasks. Question: If I know the session ID (something like "wuuZ2Gwgxw"), how do I (find and) end that particular session programmatically in ObjectScript - i.e., the equivalent of %session.EndSession=1 in the csp page code?
I am trying to create a HS.FHIR.DTL.vR4.Model.Resource.Encounter message based on a conversion of HS.FHIRServer.Interop.Response QuickStream to a JSON %Dynamic Object.
When I try to send the HS.FHIR.DTL.vR4.Model.Resource.Encounter onto the Router
How do get the item name of a class? I have several items derived from the same class, and for error reporting I want to get the name of the item which created it, rather than the class it is derived from from.
e.g. InPhase.LEGACY.GetUpdateNotification, InPhase.LFPSE.GetUpdateNotification and InPhase.ADHOC.GetUpdateNotification are all derived from the same class InPhase.Services.LoadInPhaseUpdates
I've been trying unsuccessfully to use a parameter function within a routing rule. I can see the function %GetParameter available in the WYSIWIG rule editor, but I cannot seem to get the inputs for it correct, e.g.
Is there a wizard to override pieces of class (parameters, properties, methods, etc.) like there is in Studio? I can't find this functionality anywhere. If it's not there, it's certainly a piece I'll sorely miss as we transition to VS Code.
In tracking down some of our Orphaned message issues, I was wondering if setting our EnsLib.SQL.Snapshot variable equal to "" was the same as calling the .Clean() method on EnsLib.SQL.Snapshot? Are they the same?
should I be possibly using ##class(EnsLib.SQL.Snapshot).%Delete() instead?
If anyone has experience debugging Embedded Python or has insight into why an ObjectScript method when called from a Python method would not work but would work when called directly via ObjectScript or in a Python shell, your help would be appreciated!
We have an ObjectScript ClassMethod called GetTemplateString() which takes in a templateName of String type and uses the template name to get the template object, access the Code, and read the code into a templateString. The string version of the Code is returned.
Traditional Caché Objectscript has the multi-dimensional array as its main form of complex data structure and the $order command as the main means of traversing said data structures. But newer versions of Caché ObjectScript also have data structures that are direct parallels of what languages such as JavaScript provide, in the form of %DynamicObject and %DynamicArray. These have an easy to use iterator feature via the %GetIterator method, and even a handy built-in literal syntax for constructing new objects.
I was looking for an easier way to build the FHIR Query String, given the Record Map request that is passed into the DTL.
I built this Function, but when I run a message through it, my Query String that is passed back into the DTL is a Reference Pointer and not the String I am looking for.
In PHP, I'm able to utilize the implode and str_getcsv functions to convert a comma-delimited string to a tab-delimited string. The following is an example.
As I begin our adventure into using an External FHIR Repository, I wanted to see what opinions people have about a design Idea I was working on.
I want to create a way that my Team has the ability to send a Message Type, and the system knows from that Message Type which FHIR queries to execute and return the Response back to the user, sort of like a FHIR Query Hub. Does this sound reasonable?
My purpose is to encrypt a communication using JWT tokens. I am developing on IRIS and my purpose is to generate a JWT token that will run on an older version of Cache (so I have to use functions that are compatible with the older version, Cache).
I wrote this code in IRIS:
s username = "user-test123" set st = ##class(%OAuth2.Utils).TimeInSeconds($ztimestamp,0) set et = ##class(%OAuth2.Utils).TimeInSeconds($ztimestamp, 60*15)
