Hi,

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?

Introduction

If you're solving complex problems in ObjectScript, you probably have a lot of code that works with %Status values. If you have interacted with persistent classes from an object perspective (%Save, %OpenId, etc.), you have almost certainly seen them. A %Status provides a wrapper around a localizable error message in InterSystems' platforms. An OK status ($$$OK) is just equal to 1, whereas a bad status ($$$ERROR(errorcode,arguments...)) is represented as a 0 followed by a space followed by a $ListBuild list with structured information about the error. $System.Status (see class reference) provides several handy APIs for working with %Status values; the class reference is helpful and I won't bother duplicating it here. There have been a few other useful articles/questions on the topic as well (see links at the end). My focus in this article will be on a few debugging tricks techniques rather than coding best practices (again, if you're looking for those, see links at the end).

Hey I am very new to Intersystems Objectscript and I am trying to find a way of extract 4 digit numbers from a stream.

I have a stream full of results

2334

3434

5543

4334

And I am trying to remove each 4 digit grouping from the stream.

I have tried the following for loop

for i=1:1:$length(result) {

set curr = $extract(result, i)

write !, curr

set count(curr) = $get(count(curr)) + 1

}

Unfortunately the loop extracts one digit.

Hi Community,

We're pleased to invite you to the upcoming webinar in Spanish called "Learning ObjectScript from scratch"!

Hi developers!

I have an existing CSP app and I want to add a role to it. How can I make it programmatically?

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

Announcing gj :: locate. A simple extension for VS Code that will help you get to the source of your errors.

In VS Code, using either the Serenji extension or the basic InterSystems objectscript extension, this small add-on will open the appropriate class or routine and position you at the exact line where an error occurred.

No more tedious counting of lines to find <UNDEFINED>zCredit+206^Ledger.Invoice.1. Instead, with gj :: locate you can get there with just a couple of clicks.

This 20 second video tells it all:

Hi Community,

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?

Example of what I am trying to do:

I checked out a Git-Branch and want to Import all Objectscript-Objects to my localhost.

While using Import without Compilation I receive a lot of errors.

request to http://127.0.0.1:57772/api/atelier/v3/TSTCBW/doc/MusLT01LCOD.int?ignoreC... failed, reason: connect ECONNREFUSED 127.0.0.1:57772

While using Import and Compile I receive much more of this errors.

Is there a setting, that I have to key in?

Hi folks!

Often while debugging you want to know the values of all the parameters.

Using VSCode Debugger is not an option.

What do you use to know what parameters came to the method?

My hope if you have a "magic" macro that will store all the variables with their names into a global?

And share your approaches, please?

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.

s keywords="This,blob,text"

s text = "This is a sample blob of text"

i text[keywords w "hit"

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?

Thanks!

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:
