This article is a follow-up to the previous one on how to migrate from popular databases (like PostgreSQL and MySQL) to IRIS.
We will use the same procedures utilized to migrate from PostgreSQL. However, you will see that it is even easier since the data types in MySQL are very similar to IRIS. That is why we will not need to create transformation rules in the columns.

Get the sample data to the migration process

In GitHub it is possible to download a docker-compose project to build and run 2 databases:

  • Source Database: MySQL database Docker instance with a sample database.

In this article I will explain the usage of %SQL_Diag.Result and %SQL_Diag.Message table along with all-new LOAD DATA functionality.

It is recommended to go through LOAD DATA documentation first. 

After successful operation LOAD DATA insert one record in %SQL_Diag.Result table and details are inserted in %SQL_Diag.Message table


Below is the basic command when table is already created and source file does not contain header row. 

LOAD DATA FROM FILE 'C://TEMP/mydata.txt' 
INTO MyTable

The file name must include a .txt or .csv (comma-separated values) suffix and both source and target have the same sequence of data columns.

Loading from File Source: Header

* In-Platform Agent-Based Simulation of a Connected Factory Cluster

Author: Sergey Lukyanchikov, InterSystems

1. Purpose

In this paper we prototype and explore how multiple agent-based models of robotic factories connected to other robotic factories (represented by their respective models) can be orchestrated using an all-purpose data platform – thereby simulating descriptive and predictive properties of a group of factories (a factory cluster).

From IRIS 2021.2 is possible write Class Methods using the Python Language. I used this new feature to detect persons and objects into images, using ImageAI (https://github.com/OlafenwaMoses/ImageAI). The ImageAI creator defines it as: "An open-source python library built to empower developers to build applications and systems with self-contained Deep Learning and Computer Vision capabilities using simple and few lines of code." In this article you will learn how to apply AI Computer Vision to detect object and persons inside images.

Question Steve Pisani · Jan 29, 2022

Hi,

What is the Python syntax I can use from a ClassMethod (developed in an IRIS using embedded Python), in order to invoke another class method,

- in the same class; and

- in another class.

I see 'self' is synonymous to use $this (..) in ObjectScript, but these are ClassMethods I am invoking, and self did not seem to work.

thanks - Steve

If you need create a upload REST API with IRIS is very simple. Do these procedures:

From Postman client you send a file

P.S.: It is a multipart form with a file type using "file" in the name. The request type is form/multipart. See the http request:

POST /image-analyzer/postFile HTTP/1.1
Host: localhost:52773
Content-Length: 213
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="/C:/Users/yurim/OneDrive/Imagens/salesschema.

I have created a package that offers a utility to load a Global into JSON object and reverse     
to create a Global from this type of JSON object. Academic refers to the structure created.
Each logical node of the Global is presented separately with all its descendants.
Even if they don't contain any stored data.

We recently encountered an Embedded SQL issue while upgrading to IRIS 2021.1, and thought the issue and workaround might be interesting to share.

Key takeaway:  Host variables in an ORDER BY clause of an embedded SQL query that is inside of a method don't work as expected. IRIS versions starting with 2020.1 are affected. As a workaround, add the host variable to the Method's PublicList list and "new" them so the embedded query has access to them.

It's come to our attention that the built-in license in the InterSystems IRIS and IRIS for Health 2021.1 Community Edition release is incorrectly set to expire on October 30, 2021.  

There is no impact to any production versions (the Community Edition is for development purposes), but developers will find that their instances stop running and should replace them with new ones.   For cases where replacing them is an issue, we have provided an override key.

I apologize for any inconvenience this may cause.

Question Kevin McGinn · Jan 26, 2022

I am working with a client database that is growing exceptionally fast ( about 15G/day).  As I understand it, the usage of the global ^STMONITS to gather statistics can consume a large amount of database space. This client in question is using this global. I would like to determine of the 1.7T size of the database, how much is being consumed with statistics data by the usage of the ^STMONITS global. Is there a method to get this value whether a size or percentage of the database overall size.

Hello,

I have been tinkering with FHIR recently and tried to update the FHIR servers Capability Statement after I made some changes. I updated an OAuth2.Issuer Service Registry entrys URL and needed to update the metadata which the FHIR server sends to the client so they can get the updated URL for the authorization server we use.

However, when I run the Console Setup tool with

do ##class(HS.FHIRServer.ConsoleSetup).Setup()

I get an error while the update is happening that %ZHS.HC.OAuth2.Utils class cannot be found. I wonder why this happens.

<xsl:if test="$Value = 400">
