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.
Are there any direct command to find the length of subscript of global variable? Is it possible to code in objectscript to find the maximum length of subscript in a global variable.
Besides objectscript's own list, array data structure, are there any other data structures that have been implemented, similar to the "collection" package in java, or is there a ready sorting tools for the collection class.
I am working on tweaking our current patient load process. The roster input is in text pipe delimited format, parsed out and transforms it to a standard HS.Message.PatientSearchRequest, and send to business process for patient matching. Result is transformed into a standard ADT HL7 message using EnsLib.HL.Message class. I would like to know if there is another class I can use that will transform my output to a text flat file pipe delimited instead of HL7 format? any advice on how to do this is greatly appreciated.
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.
I'm looking for a way to get the message header ID for the current message in a Request to a Business Process.
I've located some code that gives me what I need, but it runs the risk of violating the "abstraction layer" ISC has in place around such things. And while I very much appreciate their efforts at keeping things simple for me ... well, sometimes you just have to dig through the guts to get what you want.
Is there a documented, deprecation-resistant method for getting at %Ensemble("%Process").%PrimaryRequestHeader.%Id() from within a BP?
I've been tasked with an interface that needs to supply some additional metadata for the indexing of HL7v2 messages. After toying with a couple of ideas, I thought that it would be useful to subclass EnsLib.HL7.Message, add a %DynamicObject property, and store the metadata in it (it ends up getting sent to the target in JSON form anyway).
Awhile back the Developer community helped me with a situation I was having... How to loop through a Repeating Segment and Single Filed, example OBX().5, within a Business Process Rule and compare it against a Data Lookup table.
Well now I need to take it a step further. I need a way to loop through OBR() segment, and loop through OBR().4() and the subfield 4.1 and compare it to a Data Lookup table.
So I thought I could copy my existing function code and add another level to it, but its not returning what I would expect.
Hi! I have a promblem with ##class(%File).Exists -method and scandinavian characters.
Ensemble: Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2018.1.2 (Build 309_5U)
I have a business service (EnsLib.EDI.XML.Service.FileService (charset=binary)) which reads XML-files from the server and transmits those to the business process. BP request class is EnsLib.EDI.XML.Document. In BP I have code block
I am updating the PV1 segment with values from the database but when I get two values back I dont know how to separate them with a tilde and insert. Any advice for me on that?
so if I get two values returned
my PV1.7 segment should be :
My current code is as below: It works fine for one value, but when there are more than 2 values returned I need to find a way to include it
Following instructions on this page https://docs.intersystems.com/latest/csp/docbook/Doc.View.cls?KEY=D2IMP_... I am trying to create a Data Connector to be used as a base class for a cube with update support. That page suggests that putting an SQL query inside XData block is not suitable for a Data Connector that supports updates. Later it also suggests that to enable updates your SQL query must include
I am trying to access another process's content of objects like %request and %session. I am using the class/method "%SYS.ProcessQuery:VariableByPid". Does anyone knows how to get the value of the properties like %request.Data("ID",1) from one process that is running on the DB server?
I have a CSP page that is supposed to show some user info (Full name and some other properties retrieved from AD)
I am unable to get them outside of %SYS namespace using Security.Users class. Is there another mechanism to do that, or I am using Security.Users class incorrectly?
anyone know of a simple way to search a blob of text from a list of keywords in one fell swoop, without having to iterate through each keyword and perform an individual search? Ex.
We have a Unicode installation of Cache'. A client wants to send us documents that will be machine-read and loaded, automatically. They want to create the documents in ISO-8859-1 ("Latin-1"). We'd need to convert the text to UTF8 for our system. I saw the documentation on the $ZCONVERT function, but I didn't see this option. How should it be done?
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?
Background: We have our own SQL map that predates InterSystems'. A program writes an XML file for each table map class as $system.OBJ.Export would. $system.OBJ.LoadDir loads the XML files into .cls files.
The reason is a long story, but we need to update parameter EXTENTSIZE (only) in existing classes. This does not seem to happen. As a test I used $system.OBJ.Export to make an XML file and edited EXTENTSIZE in the two places it appears in the XML:
A while back I asked the developer community for a way to loop through repeatable HL7 segments and check them against a Data Lookup table within a Business Rule.
Is there an easy way to see if a class object has been compiled or needs to be? Or to get a list of classes that need to be compile in a particular namespace?
I have a process where I create a new %Stream.FileCharacter object, specify the filename (including it's path), write data to the stream, and then save. However for some reason, if the user account does not have write access to the directory, the %Save method is still returning true even though it was unable to actually write the file to the folder.
The location is a UNC path, and I'm wondering if this is tripping me up?
I had a challenge recently where I was asked to parse and iterate JSON to find a patient that has a forename = "Bill" and try to make the function that iterates through the code re-usable.
Being working in Healthcare there isn't much experience or demand for parsing JSON, as most of my work is HL7.
I took this on using the documentation and worked out a way to parse the JSON (see posts below for code and source data).
In previous versions of cache I used to be able to write click on a class and get a delete class option but in this version I can not find the delete class option was wondering if there is another way to delete a class if you wanted to do some house keeping.
N.B. These are the classes I create not the ones that comes with cache.
