Say I have an ObjectScript object called Book. It has 2 properties title and author. It extends JSON.%Adaptor, so I can call book.%JSONExport() and get this output:

In my web service I want to have a search function that returns an array of Books along with the total number of responses, like this:

I have an SQL text index defined like this

Index TextIndex On (Text) As %iFind.Index.Basic(IGNOREPUNCTUATION = 1, INDEXOPTION = 0, LANGUAGE = "en", LOWER = 1);

If I run a query like this:

SELECT
Text
FROM Post
WHERE %ID %FIND search_index("TextIndex",'ABC')

I get 20 results with posts containing the term ABC.

But each post can contain the term ABC several times.

During runtime I build an object which is essentially a wrapper over in-memory table:

I want to use this object as a part of INSERT or UPDATE queries, based on a value of some column (the main use case one of the columns is an ID value)

What's the best way to expose the object to SQL?

My general question is how to convert to a %Library.ListOfObjects to a Python "array-like" structure for use in Matplotlib.

Specifically, I have a Line Object which is comprised of a list of Points (see classes below). I want to pass the line to Python to create a Matplotlib Path.

I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.

I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:

Hi,

I've started active use ISC VS Code extensions about a half year ago, seem to be used to use, and started to enjoy them :)

The documentation promises the

Hi there,

Please, could anyone tell me how can I set up VSCode terminal to IRIS terminal? I already saw this working in a video with docker version from IRIS Community. I have the Intersystems Extension Pack and IRIS Community locally installed.

Thanks

Hi Dev Community,

I have a persistent Document class that has a FileName string property and another Question class that has an optional one-to-many relationship with Document.

I'm trying to add a SqlComputed property to the Question class (docFileName) where docFileName = Document.FileName if there is a related Document or an empty string if there isn't one.

I'd prefer the property to be SqlComputed so that if Question.Document changes, Question.docFileName will automatically update.

Hi,

I'm using node.js to access to Iris.

Considering this globals:

^Customer(1, "Address", 1)="London"

^Customer(1, "Address", 2)="UK"

^Customer(1, "Name")="Jane K. White"

^Customer(2, "Address", 1)="Reigate"

^Customer(2, "Address", 2)="UK"

^Customer(2, "Name")="Peter R. Black"

^Customer(3, "Address", 1)="London"

^Customer(3, "Address", 2)="UK"

^Customer(3, "Name")="Paul J. Green"

I retrieve all customers with:

mydata.retrieve( { global: "Customer" },

"array",

function(error, result) {

Good evening Intersystems Community,

I want to participate in the Advent of Code 2020 and followed the installation instructions in "The Advent of Code 2020 contest ObjectScript template" (https://openexchange.intersystems.com/package/aoc2020-objectscript-template).

Unforunately I get "Error: Invalid Community Edition license, may have exceeded core limit." at the step "docker-compose build".

Hello developers!

Share the best practices: 1) saving frequently used code sections, 2) quickly finding it, and 3) quickly including it into the current program?
There was a thought for 1,2 to use DC(this resource), but the search is not always convenient not only for me

The idea on the surface is to use the git repos wiki.
Are there any other best practices?

We are currently using different iterations of Ens.Director.EnableConfig items to start/stop objects within the Interoperability Namespace. We are looking for ways to minimize our downtime as we move from AIX to a new section of our Network and Red Hat Servers.

Hi folks!

Have a question for those who are masters of interoperability.

I have a basic task of having one CSV with some data. I need to transform one column in the initial dataset and get the new csv with the same form.

What's the best approach with Interoperability?

Should I user record mapper?

Should I use streams, objects?

What is the best practice?

Hi Community!

Suppose I have a property in a ObjectScript class:

Property values As list Of %String

What an SQL query can help to return the values of the property as JSON array via SQL access (JDBC)?
