During the realization of some required functionality, I discovered that I need to use Deflate compression, and found, that IRIS does not offer any options, $system.Util.Compress, works one way open (GZIP/COMPRESS) totally different, even for the same algorithms, I see that what I would expect as a result for Deflate somewhere there, but Compress returns something more. Is there any way to get a correct result using just ObjectScript without a need to use external tools? Was it really so difficult to have Deflate implemented in the first place?

Using VECTOR_COSINE() in SQL query to perform a text similarity search on existing embeddings in a %VECTOR column.

Code is below.

Commented out sql query returns this error: SQLCODE: -29 Field 'NEW_EMBEDDING_STR' not found in the applicable tables^ SELECT TOP ? maxID , activity , outcome FROMMain .AITest ORDER BY VECTOR_COSINE ( new_embedding_str ,

Sql query as written returns ERROR #5002: ObjectScript error: <PYTHON EXCEPTION> *<class 'OSError'>: isc_stdout_write: PyArg_ParseTuple failed!

I wonder if anyone has a smart idea to extract an XML fragment inside a text document (incoming from a stream)?

The XML fragment is surrounded by plain text.


<?xml version="1.0" encoding="UTF-8 ?>

The XML is not represented by any class or object in the Namespace.

The XML can look different from time to time

Hi Guys,

I'm converting our system from Ensemble 2014 to 2018 and we do have Security package of classes in deployed mode in our 2014 (eg. Users, Role, ...etc) which doesn't exist in our newly installed 2018, so how can I include those classes in 2018?

Hi everyone,
I have this global with 2 informations in it: Reference (ex: 1329) and Code (ex: JMMK-G1D6).

^DataTest = 3
^DataTest(1) = $lb("","1329","JMMK-G1D6")
^DataTest(2) = $lb("","1516","AMEV-GVPF")
^DataTest(3) = $lb("","2333","4QC6-4HW3")

With ObjectScript, i want to test if Reference 1516 exists in the global.
In the InterSystems portal, i can do it with SQL (SELECT count(*) FROM DataTest where Reference = '1516'), but can we do the same in ObjectScript without SQL and manipulating the global directly ?

Hello everyone, I need some help.

I have to send some events for a government WebService that I already imported the WSDL and XSD's and It worked fine and I'm able to build the message and connect into the service, but It has been rejected with the message that the XML is wrong and the only diference between the Caché SOAP message to all the examples that the government gave us is the header:

This is how the Government is expecting the message:

We're getting a string sent to us by a client that was compressed using a java deflater (the zlib algorithm) and when trying to use $System.Util.Decompress() I get an "illegal value" error. I gather from other community posts that this is because the raw compressed string is missing the customized wrapper Iris automatically adds. I know this has been a longstanding issue for a while...just wanted to check if there'd been any updates to this functionality, or successful workarounds for decompressing raw zlib compressed data. Thanks in advance!

HowTo VSCode O

Hello all !!! I have a question: i heard it is possible to write Object Script code for Intersystems in VSCode. How it is possible to connect the InterSystems terminal to VSCode terminal ? I heard there should be a special docker. Currently i am trying to run a simple code which will communicate with the user through the terminal but it throws an error. thank you in advance for the answer !

Hi everyone.

Is there a sensible approach to having a lookup table in Namespace A, and then accessing this from Namespaces B, C, D (etc)?

I'm trying to avoid creating a Global mapping of the lookup table global (^Ens.LookupTable) as I fear that it would then link all other lookups in that global and lead to some unexpected behaviour, but would be open to trying something in this realm if it's the best option.

Hi all,

I was wondering if there is a way to modify the results you get in the code assist in Visual Studio Code. Ideally even per class or package.

For example: the code below is for a custom component of a framework. From all the options listed I'm only interested in my own property "Title" and I don't want to see any %-methods or auto-generated methods like "TitleSet" and "TitleGet".

I am using embeded python to utilize some pythonic library but i got a problem on my hand.

One of the python function i am using return multiple values

in python you would do something like that :

val1, val2, val3, = function(params)

In COS I got something like that :

lib = ##class(%SYS.Python).Import("lib")
val1 = lib.function(params)

And I don't know how to get the second and third values.
Is there a way to get them?

For example, I have two timestamp values ('2024-04-01 10:00:00', '2024-04-01 11:30:30'). I would like to find the difference between these two timestamps, and I need the result in hours:minutes:seconds (hh:mm:ss) format.

Expected Output: 01:30:30

Note: I need an SQL query command. I should not use ClassMethod, Function, or Stored Procedure.

Could anyone please provide me with an SQL query for my question?

Hi all,

I have a situation where I am writing to global from different processes - let's call it an Event Queue.
There is then a different process that uses $order to read through the data - the PubSub processing BP.

Sometimes the writing of this global will form part of a transaction that also insert data into other tables, using tstart and tcommit.
If there is some issue, it will roll back, and the entry written to the global will also roll back.
