Hey Developers,

We know you've been waiting for this for a whole year. The time has finally come!

Join the Advent of Code 2022 with InterSystems and participate in our ObjectScript contest to win $$$$ prizes!

I can't do it from the Management portal due. I get a message that DDL is not enabled. So how else do I drop the table?

Our previous code golf ended with an overwhelming win, so now it's time for another one.
Parenthesis Hell is a Lisp-like esoteric programming language(esolang).
As a Lisp-like language, the code consists only of nested matched pairs of opened and closed parenthesis.
Your task is to write a method that receives a string of parenthesis and returns 1 if the order of the parenthesis is valid. For example, the string of parenthesis (())() is valid because it contains a matched pair of opened and closed parenthesis at each position. The string ()((()))) is not valid because it contains one unmatched parenthesis.

I have a simple app which tries to establish a connection with a Cache database instance via Global API for Java:

import com.intersys.globals.Connection;
import com.intersys.globals.ConnectionContext;

public class Assignment {

    public static void main(String[] args) {
        Connection connection = ConnectionContext.getConnection();
        connection.connect("SAMPLES", "_SYSTEM", "SYS");
    }

}

The expection I am getting:

Why SSH ?

If you do not have direct access to the server that runs your IRIS Docker container
you still may require access to the container outside "iris session" or "WebTerminal".
With an SSH terminal (PuTTY, KiTTY,.. ) you get access inside Docker, and then, depending
on your needs you run "iris session iris" or display/manipulate files directly.

Note:

An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.
For example, the word anagram itself can be rearranged into nag a ram, also the word binary into brainy and the word adobe into abode. Wikipedia

I am trying to fetch the data from cache database. But i got the error like "CSP application closed the connection before sending a responce".

Below is the query.

SELECT
CallbackComment
FROM SQ.CBPhoneResult_View Where PhoneDateODBC = '2018-04-09'

I have investigated and found that "CallbackComment" contains the special character single quotes " ' " for one result and due to this i got this error.

In this field data is enter by customer. so we cannot restrict them like Do Not use single quotes.

I would like to start a discussion regarding Caché Objects and Caché SQL.

It is my understanding that the creators of Caché Objects see Caché SQL as the reporting arm of Objects and as such SQL is essential to Caché Objects.

I once met a Caché Objects programmer who was writing code to $Order through the Globals because that person thought that Caché SQL was too slow and inefficient. I attempted to convince the person otherwise.

So, what say you? Is SQL essential to Caché Objects?

Currently, when we want to write data to a file that will be viewed in Excel, we parse the data in tab deliminated format to the file and name it with .xls at the end. That is sent to end users via email. They get a warning that the data is not formatted properly (it's not really an Excel file after all) but it does display somewhat correctly as the tabs are understood (this does not work if we deliminated with commas however).

Hi Community!

Sometimes I meet a method which accepts 10+ parameters.

And often I need only the 8th parameter to pass. And I call the method something like:

do ##class(Some.Feature).Method(,,,,,,,"flag")

And I don't like this method when I call it like this cause, you know, often I just miss the number of commas and raise some other flag I wanted.

How do you avoid this situations?

If you meet such a code, how do you call it and sure that you didn't miss the number of ","?

What is a good number of parameters in a method and f you need to pass more parameters in a method what do you do?

Hi Developers!

In March we are starting our first InterSystems IRIS Programming Contest! It's a competition in creating open-source solutions using InterSystems IRIS Data Platform.

The topic for the first contest is InterSystems IRIS, Docker and ObjectScript!

The contest will last three weeks: March 9-31, 2020.

Prizes:

There will be money prizes for Experts Nomination - winners will be determined by a specially selected jury:

🥇 1st place - $2,000

🥈 2nd place - $1,000

🥉 3rd place - $500

Also, there will be Community Nomination - an application that will receive the most votes in total:

🏆 1st place - $1,000

And we provide winners with high-level badges on Global Masters.

Hi Community! I need your advice.

The method below is 6 times slower on production server than on developing machine:

Hi developers!

As you know InterSystems IRIS besides globals, object, document and XML data-models also support relational where SQL is expected as a language to deal with the data.

And as in other relational DBMS InterSystems IRIS has its own dialect.

I start this post to support an SQL cheatsheet and invite you to share your favorites - I'll update the content upon incoming comments.

Here we go!

We've been tasked with developing a file upload module as part of our wider system, storing scanned documents against a patients profile. Our Intersystems manager suggested storing those files in the DB as streams would be the best approach and it sounded like a solid idea, it can be encrypted, complex indexes, optimized for large files and so on. However the stake holder questioned why would we want to do that over storing them in windows folders and that putting it in the DB was nuts.
