Cache Studio for IRIS 2024.3

Greetings,

As a long time Cache developer is there a way to get a copy of the Cache Studio that supports IRIS 2024.3? I do not have a WRC account? I need Studio just to experiment, not to build commercial software.

Thank you,

Everardo

I need to reproduce a table (in fact a view, but let's start with a simple table 😊) in IRIS as the currently used in Oracle.

I need to expose/project one column to JDBC as CLOB, in my class I have the corresponding property defined as:

Property GlobStream As %Stream.GlobalCharacter;

In JDBC this column is projected as LONGVARCHAR, this is compliant with the documentation but I need to project it as CLOB.

In addition, I'm no expert in JDBC but wit seems that LONGVARCHAR has a Maximum Length 32,700 characters in JDBC, not quite enough for an arbitrary stream.

We are attempting to "Repoint" old class data to new class data to save disk space and data redundancy across multiple tables. This works to a point. In essence the two classes are sharing the same data / Index / stream globals. But if an ID in the Old_Class is opened, a property is modified, and saved the property that is in the New_Class (but not in the Old_Class) is NULLed / blanked.

Intersystems IRIS Productions provide a powerful framework for connecting disparate systems across various protocols and message formats in a reliable, observable, and scalable manner. intersystems_pyprod, short for InterSystems Python Productions, is a Python library that enables developers to build these interoperability components entirely in Python.

Hi,

I'm having a problem with %JSON.Adaptor and "list of" binding.

For exemple, this class with a property "oazisCode As list of %String".

Class User.ADGroup Extends (%Persistent, %JSON.Adaptor)

{
/// Code interne
Property code As %String;

/// Libellé
Property text As %String(MAXLEN = "");

Property oazisCode As list Of %String;

}

The first time call to %JSONImport works properly

Hi everyone,

This is the first time I'm dealing with a request of modifying a variable value in a UDF OnSQLTrigger on InterSystems TrakCare.

I can't find any documentation to address this issue, but basically, my goal is to modify the value of one of the fields in a table when it is first inserted.

This is basically what the code should do, namely, to change the content of the %d variable at a specific key.

Why do these clauses affect SQL performance?

select ID from some_table where row_status in ('I','U') order by ID limit 5 - makes the query infinite
select top 10 ID from some_table where row_status in ('I','U') order by ID - the same
select ID from some_table where row_status in ('I','U') order by ID - is fast

Actually there are no rows in the table having row_status 'I' or 'U'.

I asked Gemini and it recommended me rewrite the query as

In this article, I aim to demonstrate a couple of methods for easily adding validation to REST APIs on InterSystems IRIS Data Platform. I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!
