InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

Dynamic SQL to Dynamic Object

Hello community! I have to work with queries using all kinds of methods like embedded sql and class queries. But my favorite is dynamic sql, simply because of how easy it is to manipulate them at runtime. The downside to writing a lot of these is the maintenance of the code and interacting with the output in a meaningful way.

As a developer, you have probably spent at least some time writing repetetive code. You may have even found yourself wishing you could generate the code programmatically. If this sounds familiar, this article is for you!

We'll start with an example. Note: the following examples use the %DynamicObject interface, which requires Caché 2016.2 or later. If you are unfamiliar with this class, check out the documentation here: Using JSON in Caché. It's really cool!

iris.node not found

I followed the instructions in the documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls... (Install iris.node on nodejs for windows). Procedures made:

=> Copy iris.node to the location specified in the NODE_PATH environment variable: C:\Program Files\nodejs

=> I used: var irisobj = require('iris') on my js file

But is not work. Error: The specified procedure could not be found.

Hi all,

we are wondering if anybody has a reporting tool that is capable using IRIS Objects?

I know there are things like Crystal Reports and others out there who can read the SQL Data throug ODBC but we need the capability of using object methods while running the report.

Since now we where using a JAVA based report generator (ReportWeaver) but since the object binding for JAVA doesn't exist anymore in IRIS data platform, did any of you have an alternative report generator?

Looking forward to any answers

cheers

Stephan

Install EnsDemo on IRIS

Has you may know, EnsDemo from Ensemble are not available anymore on IRIS.

This is a good thing, Iris is cloud oriented, it must be light, fast. Now the new way of sharing samples or modules is through git, continuous integration and OpenExchange.

But, in some cases you want to go back to your good old samples from EnsDemo to get inspiration or best practices.

Good news, there is a git for that :

Hi guys!

As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).

1. Get it by as a property of an instance with "Object access":

ClassMethod GetPropertyForID(stId As %Integer) As %String

{

set obj=..%OpenId(stId)

return obj.StringData

}

2. Get it as a value of a column of the record with "SQL access":

Presenter: Dan Kutac
Task: Use a common login identity and a central mechanism of authentication across environments from multiple entities
Approach: Provide examples and code samples of an application environment using OpenID Connect and OAuth 2.0

Description: In this session we will demonstrate an application environment using OpenID Connect and OAuth 2.0. Hear how this is done and what options you have; and yes, you get to keep the code.

Problem: How to use a a common login identity (e.g. Facebook credentials) and a central mechanism of authorization cross environments from multiple entities.

Solution: Create awareness and interest in using OAuth 2.0

Transaction suspencion

It’s often useful to make changes inside the current transaction, that would not be rolled-back if transaction is rolled-back. For example to do some logging.

This can be achieved by using global that is mapped to temporary database -- IRISTEMP. All globals that start with ^IRIS.Temp* are mapped to IRISTEMP by default. Problem with such approach is that IRISTEMP is cleaned on InterSystems IRIS restart, so this log is lost.

What else you can do is -- suspend transaction temporarily, do the logging, and then resume the same transaction.

Hi! I am working in a java project (Spring Boot+ Maven + Hibernate) using jpa/hibernate to manage the persistance with the IRIS database from the Docker image (store/intersystems/iris:2019.2.0.107.0-community) and I've found an issue using the IRIS instance, when I define tables with relationships OneToMany, ManyToOne or ManyToMany and I try to fetch all the rows of the tables using the default method findAll (JpaRepository implements that method to get all the rows by default) the query automatically exceeds the limit of licenses availables.

Using Regular Expressions in Caché

1.About this article

Just like Caché pattern matching, Regular Expressions can be used in Caché to identify patterns in text data – only with a much higher expressive power. This article provides a brief introduction into Regular Expressions and what you can do with it in Caché. The information provided herein is based on various sources, most notably the book “Mastering Regular Expressions” by Jeffrey Friedl and of course the Caché online documentation. The article is not intended to discuss all the possibilities and details of regular expressions. Please refer to the information sources listed in chapter 5 if you would like to learn more. If you prefer to read off-line you can also download the PDF version of this article.

Have enabled LDAP for our numerous , Ensemble, IRIS and cache instances with many namespaces. All is working fine and the ldap logins work.

But have noticed that the first instance that the user logs into the namespace is assigned to that user, but when that user than logs into another instance the default namespace from the first login is still there and doesn't update to the new namespace.

So this doesn't effect the ldap login but is now effecting the terminal logins where the user is now getting access denied.
