Hi developers!

Just want to share an old but always relevant best practice on namespaces changing @Dmitry Maslennikov shared with me (again).

Consider method:

classmethod DoSomethingInSYS() as %Status

{

set sc=$$$OK

set ns=$namespace

zn "%SYS"

// try-catch in case there will be an error

try {

// do something, e.g. config change

}

catch {}

 zn ns    ; returning back to the namespace we came in the routine

return sc

}

And with new $namespace the method could be rewritten as:

classmethod DoSomethingInSYS() as %Status

{

set sc=$$$OK

new $namespace

set $namespace="%SYS"

// do something

return sc

}

So! The difference is that we don't need to change the namespace manually as it will be back automatically once we return the method.

and we don't need try-catch (at least for this purpose) too.

I have been working within Objectscript for a few months and I am seeking assistance today because all of the help files within the docs.intersystems.com domain are currently down and they wont be back up until next week. (I raised a special ticket for this) 

Hi folks!

Want to share a lifehack with you on ObjectScript highlighiting withing VSCode for script files.

Script files are just files with lines of ObjectScript that we feed anywhere, e.g. into IRIS during Docker baking procedure.

Typical usecase - here is the Scriptfile

here is the Dockerfile where we feed it.

And here is how it looks like usually in VSCode:

Coudl be more beautiful, right?

Hi,

How to check if data string contains Unicode characters?

Thanks

I have a routine tag that takes an argument and I want this argument to be an array reference.  So I try something like:

do mytag(.myarr)

The mytag tag, adds subscripts to myarr.

When I evaluate myarr after the tag call, only the subscripts passed in are retained in myarr.  The subscripts added by mytag are missing.  Is there a way to pass an array so it will behave the way I want it to?

Hi,

When for any particular reason I need to update a record and don't want to pull the triggers, the keyword %NOTRIGGER can be used. But I've been trying to do the same when I change the row using the object approach, but I can't find it. Anyone knows if it's possible to avoid pulling triggers when working with objects?

Sadly, the utility "DISABLE^%NOTRIGGER" doesn't seem to exist ;-)

Thank you,
David

Hi!

Does anyone have a cleaner approach than this for looping through grouped NTE segments in order to set the segment ID in an ORM? I am aiming to avoid the NTE segments that may follow the PID segment and find the NTE's that follow the OBR segment. By using the below If statement in the While loop, I'm finding NTE's that have comments in the fourth field (PID NTE's tend not to have these in the messaging I'm seeing, I'm awaiting confirmation on this), as well as finding my newly inserted NTE segment using $FIND to locate the colon (I've concatenated some values).

I'm thinking to try ChunkedWriter based on the documentation I'm reading to solve an issue but could use some clarification. Anyone that could provide a usage example of this down below?

To send a chunked request, do the following:

Good afternoon I am making a method of a class that I want to return a list of objects of another class that I have defined, example:

ClassMethod myMethod() As list of MyPackage.MyClass
{
}

But it gives me a syntax error, I try this and it works:

ClassMethod myMethod() As %ListOfObjects
{
}

But I would like to keep the typing.

Is there a way?

Hello All

I'm running into an issue performing UPDATES that I'm not getting on INSERTS. It's probably obvious, but I'm just not seeing it and could use a little help.

I'm going over an HL7 message and depending upon varying criteria, the relevent variables will get items added to them like the following:

Set patientId = pRequest.GetValueAt("PID:3")
Set sqlColumns = sqlColumns_",patient_id"
Set sqlValues = sqlValues_",?"
Set par($i(p)) = patientId

After compiling the variables, I check to see if accession number is found in the table.

Hi Community,

This post is to introduce one of my first project in COS, I created when started to learn the language and until today I'm keeping improve it.

The CosFaker(here on Github) is a pure COS library for generating fake data.

cosFaker vs Populate Utils

So why use cosFaker if caché has the populate data utility?

A VIEW in SQL is basically a prepared SQL statement.
It has to be executed and assembled like any other SQL query.
MATERIALIZED VIEW means that the content is collected before hands and can be retrieved rather fast.
I saw the concept first with my favorite competitor named O* and they made a lot of noise about it.
  { favorite: because I could win every benchmark against them }

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.

Greetings, InterSystems community!

I am pleased to announce that the web terminal project, Caché WebTerminal version 4 gets its release! After long period of enhancing this web application from 2013, it came to the version 4, which features major stability and security improvements, intelligent autocomplete and syntax highlighting, convenient SQL mode and a lot of other useful features.

The goal of this article is to spread the knowledge about this project over the InterSystems community.
