Due to MySQL's interpretation of SCHEMA differing from the common SQL understanding (as seen in IRIS/SQL Server/Oracle), our automated Linked Table Wizard may encounter errors when attempting to retrieve metadata information to build the Linked Table.

(This also applies to Linked Procedures and Views)

Hi Community,

On Windows, this cannot be changed, but on Unix-like platforms, it can be changed using the iris rename command.

iris rename instname(<current instance name>) newname(<new instane name>)

For more information about the iris rename command, please refer to the following document:

The rise of Big Data projects, real-time self-service analytics, online query services, and social networks, among others, have enabled scenarios for massive and high-performance data queries. In response to this challenge, MPP (massively parallel processing database) technology was created, and it quickly established itself. Among the open-source MPP options, Presto (https://prestodb.io/) is the best-known option. It originated in Facebook and was utilized for data analytics, but later became open-sourced.

Over the years, I’ve noticed that certain SQL questions come up repeatedly on the InterSystems Developer Community, especially about using the LIKE predicate in different contexts. Common variations include:

• using special characters in queries
• using variables in queries

and many more derivatives. So, I decided to write an article that focuses on how LIKE works in InterSystems IRIS SQL, especially when used with variables in Embedded SQL, Dynamic SQL, and Class Queries, while touching on pattern escaping and special character searches.

First of all, I'd like to mention that InterSystems IRIS SQL offers most of the capabilities available in other relational DBMS that implement a later version of the SQL standard. But at the same time, it's important to mention that apart from relational access, in IRIS you can also use other models to get the same data, for example, object or document models.

On this note, let's look at the LIKE predicate and how this tool is used in SQL for pattern matching.

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.

Hi Everyone!

The Certification Team of InterSystems Learning Services is currently developing an InterSystems ObjectScript Specialist certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.

Hello, I try to develop a REST interface where I need to interact with legacy MUMPS routines. How can I pass in input to a Read without modifying the legacy code?

I think in linux I can execute command < inputfile to read from file, but how does it work in ObjectScript?

Is it possible to install IRIS Studio as an evaluation, so I can use the built-in IDE?

I have installed IRIS Community edition that does not come with a built-id IDE.

Altelier website is down down.

Here's the final InterSystems leaderboard:

Hi everyone,

In this article, I’m excited to introduce CodeInspector, a tool designed to simplify code validation by applying custom rules tailored to your development requirements. Whether you're managing a large codebase or working in an agile environment, CodeInspector helps ensure code quality by offering flexibility and adaptability to specific project needs.

My usecase is sorting and removing duplicates and getting count from a file that has json messages as a individual rows.

I am currently planning to use pandas for this purpose as its really fast. Below are the steps i am following

1) call a python function (called function) from IRIS classmethod(calling function)

2) the call python function will read the json file in a dataframe

3) perform sorting, dup removal, count in the dataframe

4) convert the dataframe into iris stream

5) return back the stream to iris calling function class method

I have an API set up in IRIS which is secured using an IRIS authentication service, so there is a bearer token being passed down in the request header.

The August Article Bounty on the Global Masters article caught my attention, and one of the proposed topics sounded quite interesting in regard to its future use in my teaching. So, here's what I'd like to tell my students about tables in IRIS and how they correlate with the object model.

First of all, InterSystems IRIS boasts a unified data model. This means that when you work with data, you are not locked into a single paradigm. The same data can be accessed and manipulated as a traditional SQL table, as a native object, or even as a multidimensional array (a global). It means that when you create an SQL table, IRIS automatically creates a corresponding object class. When you define an object class, IRIS automatically makes it available as an SQL table. The data itself is stored only once in IRIS's efficient multidimensional storage engine. The SQL engine and the object engine are simply different "lenses" to view and work with the same data.

First, let's look at the correlation between the relational model and the object model:

It's not always a 1:1 correlation, as you may have several tables represent one class, for example. But it's a general rule of thumb.
