Hi,

I want to access a Stored Procedure in a remote SQL Server Database. I am quite new to Object script.

The stored procedure has 3 parameters: 2 datetime parameters and 1 integer.

Which is the best way to do that? I'm wondering if I can use the link stored procedure feature inside object script or some SQL statement in Object Script.

This SP returns a set of rows which I want to read, transform and save in a persistent class.

Thanks in advance,

A good writer is supposed to draw you in with the title and bury the answer somewhere in the article. I suppose this makes me a bad writer – don’t think less of me, my whole feeling of self-worth comes from the opinions of internet strangers!

Hi everyone,

I am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)

So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.

Background

InterSystems IRIS 2019 is going to introduce new and exciting features. One of the areas with new interesting must-to-know things is the API Management.

In this post I would like to talk about the syslog table. I will cover what it is, how you look at it, what the entries really are, and why it may be important to you. The syslog table can contain important diagnostic information. If your system is having any problems, it is important to understand how to look at this table and what information is contained there.

Date range queries going too slow for you? SQL Performance got you down? I have ANOTHER weird trick that SQL Developers don't want you to know!*

A quick question. What's the shortcut to uncomment multiple lines of code in Studio? And what's the shortcut to comment out multiple lines of code in Studio?

Thanks in advance!

In the WRC, we frequently see customers contact us because their Web Gateway is unable to serve web pages. This article will explain a frequent reason why these errors can occur, and explain some tools which can be used to debug the problem. This explanation is focused on the Web Gateway serving InterSystems IRIS instances, but the same explanation should apply to the CSP Gateway serving Caché instances as well.

Globals, these magic swords for storing data, have been around for a while, but not many people can use them efficiently or know about this super-weapon altogether.

If you use globals for tasks where they truly shine, the results may be amazing, either in terms of increased performance or dramatic simplification of the overall solution (1, 2).

Globals offer a special way of storing and processing data, which is completely different from SQL tables. They were first introduced in 1966 in the M(UMPS) programming language, which was initially used in medical databases. It is still used in the same way, but has also been adopted by some other industries where reliability and high performance are top priorities: finance, trading, etc.

Later M(UMPS) evolved into Caché ObjectScript (COS). COS was developed by InterSystems as a superset of M. The original language is still accepted by developers' community and alive in a few implementations. There are several signs of activity around the web: MUMPS Google group, Mumps User's group), effective ISO Standard, etc.

Modern global based DBMS supports transactions, journaling, replication, partitioning. It means that they can be used for building modern, reliable and fast distributed systems.

Globals do not restrict you to the boundaries of the relational model. They give you the freedom of creating data structures optimized for particular tasks. For many applications reasonable use of globals can be a real silver bullet offering speeds that developers of conventional relational applications can only dream of.

Globals as a method of storing data can be used in many modern programming languages, both high- and low-level. Therefore, this article will focus specifically on globals and not the language they once came from.

Hey Developers,

With the release of InterSystems IRIS 2021.2 Preview and all-new LOAD DATA functionality, we'd like to put it to the test with the new DATASETS contest!

🏆 InterSystems Datasets Contest 🏆

The question has come up several times and I saw mixed answers and no quick example

My personal preference is using CPIPE device as you get back exactly the output you will get at the command line interface of your OS .
The tricky thing is to stop reading in time.
The example just displays what you normally see in your console.
it becomes useful if you look for things that you can't get from any $system.whatever()

Hey Developers,

We'd like to invite you to join our next contest dedicated to creating useful tools to make your fellow developers' lives easier:

Launching IRIS Using Docker

I have the variable with literal.

Can I understand with ObjectScript that the literal is:

%String,

or %Integer,

or %Date,

or %Double,

or %Numeric?

What I'm looking for could be:

set variable="To be or not to be"

USER>w ##class(utils).GetType(variable) 

%String

set variable=42

USER>w ##class(utils).GetType(variable) 

%Integer
