#InterSystems IRIS

Hi Dev Community,

I have a persistent Document class that has a FileName string property and another Question class that has an optional one-to-many relationship with Document.

I'm trying to add a SqlComputed property to the Question class (docFileName) where docFileName = Document.FileName if there is a related Document or an empty string if there isn't one.

I'd prefer the property to be SqlComputed so that if Question.Document changes, Question.docFileName will automatically update.

In a tag-based CSP page, I can define (e.g.):

<script method="Foo" language="cache" runat="server">

Hello developers!

Share the best practices: 1) saving frequently used code sections, 2) quickly finding it, and 3) quickly including it into the current program?
There was a thought for 1,2 to use DC(this resource), but the search is not always convenient not only for me

The idea on the surface is to use the git repos wiki.
Are there any other best practices?

Is there a way in ObjectScript to return the OS user of the superserver? I know %SYS.ProcessQuery can find this for a given process but is there a clean way independent of a specific process ID I can find the OS user used for background jobs?

For IRIS this is usually irisusr and Caché this is usually cacheusr but may vary based on installation and upgrade history of an instance. I would find it very useful to determine programmatically if a process is running as this particular user when the username may vary.

Hi Community!

Suppose I have a property in a ObjectScript class:

Property values As list Of %String

What an SQL query can help to return the values of the property as JSON array via SQL access (JDBC)?

I need to turn off Journalling for a particular database programmatically.

How can I make it happen?

Hi All,

I am having an SQL query (mentioned below). When I am running this query it is taking 90 min to retrieve all records (approx 1 million records).

Fetching data from 5 tables using inner join in cache. Relative cost displaying 10 million

I wan to confirm How this query can be optimized

The current jdbc driver version is 3.1.0, but it is not published in the public mvn repository, only the old version, see:

https://mvnrepository.com/artifact/com.intersystems/intersystems-jdbc

It is very bad to the Java Community. And why not publish IRIS Hibernate dialect in mvn repository too?

These actions are important to Java Developers.

Hello,

I need AES ECB with PKSC7 padding for an interface.
Unfortunately, the %SYSTEM.Encryption.AESEncode cannot do this.

Therefore I wanted to include the following python lib.
PyCrptydome -> https://pycryptodome.readthedocs.io/en/latest/index.html

We need to install the package offline on the system. So I downloaded it and put it in the MGR/Python/ directory.

However, when I try to install it, I get the following error message:

Hi all,

I'm wondering if exists any command or method to replace a text using parameters.

In C# I use the Format property

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.

Hi, devs!

In ObjectScript I can refer to a class parameter as:

write ..#ParameterName

How do I do the same in Embedded Python?

I want to convert a string to uppercase that may or may not be a $LIST so that I can do a case insensitve search. However, when looking at what constitutes a $LIST I can see something that looks like it follows these rules:
