Embedded Python refers to the integration of the Python programming language into the InterSystems IRIS kernel, allowing developers to operate with data and develop business logic for server-side applications using Python.
Hi all, I am trying to execute a query like the below code. set statement = ##class(%ResultSet).%New("some_class:query_method"). // here query method is empty and with rowspec some columname
statement.Execute(param1)
I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc. How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3
In a previous question, I have illustrated a few problems using Embedded Python interactively as you would do from Docker console or IRIS terminal. Investigation of the causes brought a rather clear picture. It's a classic impedance mismatch
In my previous articles, I described my Command Line Extension to NativeAPI. Of course, this is also available for any other NativeAPI package. So I created this example in Python as a demo.
Customizing Stored Procedures with ObjectScript directly has been useful to access NoSQL storage and external messaging via integration, to present output in tabular format.
Welcome dear members of the Community to the presentation and first article of a small project that will demonstrate the capabilities of InterSystems IRIS to provide full backup functionality for a web application developed in Angular. This article will be limited to presenting the concept as well as the InterSystems IRIS functionalities used in a general way, going into more detail in subsequent articles.
Starting in version 2021.1, InterSystems IRIS began shipping with a python runtime in the engine's kernel. However, there was no way to install packages from within the instance. The main draw of python is its enormous package ecosystem. With that in mind, I introduce my side project zpip, a pip wrapper that is callable from the iris terminal.
In a fast-paced clinical environment, where quick decision-making is crucial, the lack of streamlined document storage and access systems poses several obstacles. While storage solutions for documents exist (e.g, FHIR), accessing and effectively searching for specific patient data within those documents meaningfully can be a significant challenge.
How can I refer to a classmethod of the same class while coding another classmethod with Embedded python?
I know that I can call it with iris.cls(classname).MethodName(), but it's more cumbersome even comparing with ObjectScript, where I can call ..MethodName().
Has anyone come across a good using Embedded Python to convert a Python List object to an IRIS %List object?
My use case is I want to open an SQL entry with an Objectscript class method, then pass some information from that row into a separate Python class method which will then create a Python List object, then have the Python class method return that list back to the Objectscript class method in such a way that the Python List can be converted to an IRIS %List object for me to then use in the Objectscript code.
Excuse if this is obvious to Python programmers but for those crossing over from ObjectScript this may be a useful tip.
The scenario is developing some Embedded python commands.
Testing out functionality is being confirmed via the shell:
$SYSTEM.Python.Shell()
Python 3.9.5 (default, Mar 14 2023, 06:58:44) [MSC v.1927 64 bit (AMD64)] on win32
Type quit() or Ctrl-D to exit this shell.
>>>
When Python evaluates an expression in the shell, it prints the result of the expression to the terminal.
When I started this project I had set myself limits: Though there is a wide range of almost ready-to-use modules in various languages and though IRIS has excellent facilities and interfaces to make use of them I decided to solve the challenge "totally internal" just with embedded Python, SQL, ObjectScript Neither Java, nor Nodes, nor Angular, PEX, ... you name it. The combination of embedded Python and SQL is preferred. ObjectScript is just my last chance.
Written in reply to community post for can Python create HL7 Message dynamically.
Pre-requisites and setup
Use an integration enabled namespace. Note: USER namespace is not enabled for interoperability by default. If following suggest create a new interoperatibility namespace to explore functionality.
# Switch to ZN "[Interoperability Namespace Name]"
# Launch interactive Python shell: Do $SYSTEM.Python.Shell()
Methods written in ObjectScript can use pass-by-reference arguments to return information to the caller. Python doesn’t support pass-by-reference arguments, so Embedded Python in IRIS doesn’t support them either. That's it, that's the end of the post, hope you liked it. 😉 But wait, what about the Classic Rock & Roll?
In this article, I will show you how one can easily create and read Microsoft Word documents using InterSystems IRIS with the leverage power of embedded Python.
Setup
First things first, let’s install the Python module called python-docx. There are a lot of modules to write MS Word files in Python. However, this one is the easiest one to use.
Just execute the following command on the terminal:
By update
