Hello,

When working with class queries you have to define the ROWSPEC at the beginning (See below).

Instead of using Year1 or Year2 as the column name, how can I use the passed in fiscal year (xFiscalYear)

so Instead of using "Year1" as the column name I can call it something like: "Jul"_xFiscalYear

Integrating frontend React applications with backend services like IRIS database via REST APIs can be a powerful way to build robust web applications. However, one common hurdle developers often encounter is the Cross-Origin Resource Sharing (CORS) issue, which can prevent the frontend from accessing resources on the backend due to security restrictions enforced by web browsers. In this article, we'll explore how to tackle CORS issues when integrating React web apps with IRIS backend services.

By default InterSystems IRIS expose your endpoints using http, but can be necessary run https from your dev env and/or get public internet access to your app. You can buy or get a certificate and config a gateway, spending many hours or use a great public service called ngrok. Follow the steps:

1 - Run your app, I will use FHIR template as sample, see:

1.1 download the app: git clone https://github.com/intersystems-community/iris-fhir-template.git

Hi All,

So after finally getting cache to install (by enabling root user and disabling the gatekeeper) it tells me that it has started with one alert... that is "Private web server has not started after 5 seconds." - urgh!

Obviously i need access to the management portal to continue setup, I've done lots of googling but i cant find anything on this, does anyone have any ideas?

Many thanks,

Dan

If you work with interoperability productions of InterSystems IRIS or Ensemble, no doubt you are familiar with the Message Viewer page. The page supports filtering messages according to filter criteria you enter in the Basic and/or Extended Criteria sections. Extended Criteria conditions are specified as property-operator-value triples. Once you click Search button, such triples become WHERE clause conditions of a generated SQL query executed against message header/body tables.

Rule to validate SQL syntaxis

Hi! We have received a request to create a new rule on CachéQuality to identify when a developer uses double quotes (" ") within any SQL statement.

We have been asked many times about SQL validation rules, and we would like to open a debate to allow everyone discuss what would you like to be checked on a SQL statement.

Current examples are for basic situations:

A permanent job opportunity has arisen for a Caché/Ensemble developer with at least 5 years experience. My client is a specialist resource provisioner of developers for high profile clients in the finance, healthcare, retail, distribution and credit business that are mainly based in central London. My client is looking for a highly-motivated individual who thrives in an environment where problems are open-ended.

Hi!

Consider I have a class Package.Data with Property UniqueStringValue as %String.

I introduced the Index for this property:

 Index ValueIndex on UniqueStringValue [Unique];

It works well. But if I try to check if there is an object with the certain value in code like this:

if ##class(Package.Data).ValueIndexExists(value)

this expression fails, if value="value", even if there is an instance with instance.UniqueStingValue="Value"

How can I set the index to prevent saving case sensitive values in this class?

Hi Community,

Watch this video to get an introduction to columnar storage, and see how it can be used in InterSystems IRIS data platform to improve the speed of your analytic queries and efficiently store data:

I've set up a Ens.Alert routing rule and would like to route alerts to different email groups based on business partner or alert group instead of relying on source config using Document.SourceConfigName. Is there a way to reference the business partner or alert group property in a routing rule?

This is more of an eclipse thing, but I couldn't really find an answer when I searched. I created a new workspace, but I had updated my keyboard shortcuts in the first workspace and now I'm trying to import the changes. I successfully exported them as .csv, but I cannot find a way to import the changes into the new workspace.

Any help would be appreciated.

mySQL data importer tool

Hi,

If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.

Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance.
%NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.

Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.

Hello,

I don't know if the title is accurate enough. I have a legacy code that I need to optimize. It's a routine written in objectscript. It accepts 4 parameters and runs 6 nested FOR...$ORDER reading a big global.

The thing is when I run the routine the first time it takes around 60 seconds to run. If I run it again it takes 5 seconds. If I wait around 6 to 10 minutes to run it again, it takes 60 seconds again, but if I run it every 1, 2, 3... minutes it still takes only 5 seconds to run.

For the upcoming Python contest, I would like to make a small demo, on how to create a simple REST application using Python, which will use IRIS as a database. Using this tools

  • FastAPI framework, high performance, easy to learn, fast to code, ready for production
  • SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL
  • Alembic is a lightweight database migration tool for usage with the SQLAlchemy Database Toolkit for Python.
  • Uvicorn is an ASGI web server implementation for Python.

The new production component driver for Deltanji enables highly granular management of InterSystems Interoperability Productions with tight integration into the management portal. We presented it at the InterSystems UK&I summit this week and it received a great reception. 

It solves the current pain-point of Interoperability Productions being defined in a single monolithic class definition. Deltanji source control increases the granularity with which items can be managed. Instead of versioning a single class definition containing all the configuration items, this new component driver allows individual configuration items to be managed separately. Each configuration item has its own versioning and revision history and can be checked-out, checked-in, and deployed independently of any other items in the same Production.

Because each configuration item within a production class is managed by Deltanji as a first-class component in its own right, Deltanji provides all the source control, versioning, and workflow capabilities that it provides for any other component.

Watch the below clip to see it in action. 

 

We'll be talking about this new feature in more detail at our User Group Session on November 3rd at 3pm (GMT). Register your attendance on Eventbrite here - https://bit.ly/3yqzfvS

To find out more about Deltanji, visit our website georgejames.com or drop us an email info@georgejames.com

Hello,

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:

(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()

License Server summary view of active key.

Distributed license use:

Current License Units Used = 1

Maximum License Units Used = 1

License Units Authorized = 200

Local license use:

Current Connections = 1 Maximum Connections = 1
