Hello everybody.

My question originated when trying to help a coworker...

There is a system module, specifically a ClassMethod that inserts records into a table as per the pseudocode below:

set Obj = ##class(FooSchema.FooTable).%New()
set Obj.fooProp = fooValue
// Other Foo properties //
set status = Obj.%Save()

From time to time, when trying to save the object, an error , informing that it was not possible to obtain the exclusive lock on the table instance

At the moment I am trying to write a documentation file for a project and intend to use LaTeX for it.
Has anyone already had experience with this? I haven't found syntax highlighting with the LaTeX packages I know yet.
I found a request on Pygment but it was from 2016 and there was no reply on it since then.

Does anyone know a simple way for syntax highlighting COS in LaTeX?
Thanks for your input!

Martin

I have a SQL query that I want to run against MS SQL from cache ensemble using the SQL outbound adapter. If I run this query direct from MS SQL Studio it take about 7 seconds MAX and returns about half a million rows. The row only contains one column it is a number all same size and if I run this query in the production in ensemble it takes for ever the production finishes without getting the response back. The same query run in cache outside the ensemble environment writing results to a file it returns results taking about 3minutes to complete.

Hi all,

I am trying to use a %Status property on some of my Response classes. If the execution of a service goes wrong, I set the %Status property on Response with the value $$$ERROR($$$GeneralError, "pre-defined error message").

When I check the visual trace for this message and look for the %Status (property "status_code" on the image), it is displayed like this:

If I select to display the Body of the Response, I get the 'readable' form of %Status:

Hello fellows, I need you wisdom.

In my organization we code in ObjectScript and .int everyday. When I joined nobody knew barely nothing about classes and their use was almost only for storage definition purpose. During my self-learning in caché I discovered the object oriented programming and class developing was possible in caché and started to code in .cls . Being something self-taught, I may have some basic doubts I'd have missed in my documentation readings.

Is there a straightforward workflow in VS Code for moving a class from one namespace to another on the same server? With Caché/IRIS Studio, it was a (sort of) simple export/change namespace in file menu/import operation. But in VS Code it's not obvious (to me, at least).

I can add multiple namespaces to a workspace, but when using isfs:// paths I see only a "Download" option and no "Upload" or "Import/Compile." When I'm navigating the local file tree, I see Import options, but no way to select the namespace into which I want to import.

Hi Folks,

I created a persistent class as below 

Class myclass.DataBase Extends %Persistent
{

Property ID As %String;

Property Skill As list Of myclass.SerialTablelist;
}

and Created another Serial class as 

Class myclass.SerialTablelist Extends %SerialObject
{

Property PSkill As %String;

Property OSkill As %String;
}

Now I will save the id as below

do rs.Prepare("Insert into myclass.DataBase(ID)VALUES(?)")
do rs.Execute(ID)

I'm trying to write a method that runs an OS command with $zf(-100,"/ASYNC") and then waits for it to finish before returning, but I can't figure out how to check if the child process (in $zchild) is still running. $System.Process.State($zchild) always returns "RUN" even once the child process is gone. Is there some better way to check this, short of running another OS-specific command and processing the output (which is just really annoying and unelegant)?

VSCode: Formatter not found

Hi,

I am using VSCode together with IRIS 2021.1.
When using Shift+Alt+F to reformat a class file, it pops up with the below message. When I select install formatter, it routes me to the extensions page, where it shows the extensions as being installed. Any advice will be appreciated.

JSON - NULL Properties

So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.

1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.

2. I'm not really confident enough to create JSON Type classes or backporting code, etc.

Hi

I'm using a class which extends %XML.Adaptor adaptor and I want to create an XML file with multiple namespaces, like the following:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
</soap>

However, I don't see how to do this with the code I have. So far, I have

Hi folks!

I'm curious if it is possible to change the class method to another class?

I call a method of a system class to generate another class. But there is a bug/feature in a library class, so I need to tweak a bit the generated method, e.g. add additional parameter and change the line to "if" the parameter.

I hope to do this programmatically after class generation and change the code in a way I like.

What are the options?
