#InterSystems IRIS

Is it some certain class, method, global, api, application or neither? If the entity is some of this what is the syntax?

This question originally appeared in the comments of the post: IDE platform for beginners

Hello All,

Visual studio code doesn't allow debugging of code or running of code as far I can see. Since I am new, could someone guide me on this.

Thanks

Hi all,

I am trying to delete an item from a production through a routine that installs and disables items.

To add any item, I have no problems, even to enable and disable some particular items.

The problem arises when I try to eliminate the production item, because when it does, the production become unstable and only works again when this item is added again in the collection (or the item is deleted manually in the production.cls)

This is my code attempt:

(I wasn't able to find this in the docs or the Community, so feel free to point me to a reference that I missed)

How can I determine the effective User and Group that will be used when an InterSystems IRIS process is doing file I/O on the file system for UNIX? Bonus points if you can tell me how to do it from within InterSystems IRIS as well as from the host OS.

Thanks!

Hi folks!

Do we have an embedded REST API in IRIS which accepts arbitrary SQL and returns data in JSON?

Or if anyone did something like this?

The idea is to have something like MDX2JSON but SQL2JSON.

Thanks!

Hi, devs!

In ObjectScript I can refer to a class parameter as:

write ..#ParameterName

How do I do the same in Embedded Python?

Hello,

I work as a contractor for the Department of Veterans Affairs. I want to read data from an Excel workbook. I searched posts here and saw Apache POI suggested. I believe Apache POI is not approved for use within VA. I also believe we should be able to run SQL query against Excel. Has anybody done such a thing or are there other ways to read data from Excel workbooks?

Thanks

in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?

Has anyone successfully tested the new THROUGH command in IRIS 2024.2 with a FOREIGN SERVER?https://docs.intersystems.com/iris20242/csp/docbook/Doc.View.cls?KEY=RSQ...

I have connected from a Docker instance to a VM. I was able to successfully set up the JDBC connection through the UI.

Hi,
Do you know the best way to convert a %Library.ListOfDataTypes instance to a $LIST format string?

Thanks,

Hi,
For a REST application, when a user connects, I have to write a message in an application log.
The login is processed by the /login routine by default.

How can I add a process to the login process?
Is there a callback ?
Should I create a login method in my class that extends %CSP.REST ?
I'm not sure and can't find information in the documentation ?

I try this (not working) :

<Routes>

<Route Url="/lists" Method="GET" Call="GetLists" />

<Route Url="/me" Method="GET" Call="GetUserInformations" />

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:

Hello!

I am taking the 'Creating an InterSystems Class Definition' course, and the Exercices asks to open a Terminal from the Management Portal to create and interact with a new object. I didn't found how to acces tot the Terminal from the Management Portal, and the documentation I have seen doesn't help me...

This is not an issue in ObjectScript, due to its typeless nature. But it's essential for external programming languages that care a bit more about types of variables.

And in any case, it's still reproducible in ObjectScript. I have table

CREATE TABLE some_table (
        id INTEGER NOT NULL, 
        x INTEGER, 
        y INTEGER, 
        z VARCHAR(50), 
        PRIMARY KEY (id)
)

And data

INSERT INTO some_table (id, x, y, z) VALUES (1, 1, 2, 'z1');
INSERT INTO some_table (id, x, y, z) VALUES (2, 2, 3, 'z2');
INSERT INTO some_table (id, x, y, z) VALUES (3, 3, 4, 'z3');
INSERT INTO some_table (id, x, y, z) VALUES (4, 4, 5, 'z4');
