SQL is a standard language for storing, manipulating and retrieving data in relational databases.

SQL injection remains one of the most critical vulnerabilities in database-driven applications, allowing attackers to manipulate queries and potentially access or compromise sensitive data. In InterSystems IRIS, developers have access to both Dynamic SQL and Embedded SQL, each with distinct characteristics. Understanding how to use them securely is essential for preventing SQL injection.

Hello to all the Cache Experts out there and Happy Friday!

The company I work for uses Cache 2017.1.3 and we have been seeing intermittent errors in the Cache Error Trap when an SQL query runs. The error message looks like the error is occurring within the cached query routine that Cache auto-generates. Unfortunately, when I pulled up the routine in the SMP System Explorer, I only found an obj version, so was unable to look at any code.

Are you familiar with SQL databases, but not familiar with IRIS? Then read on...

About a year ago I joined InterSystems, and that is how IRIS got on my radar. I've been using databases for over 40 years—much of that time for database vendors—and assumed IRIS would be largely the same as the other databases I knew. However I was surprised to find that IRIS is in several ways quite unlike other databases, often much better. With this, my first article in the Dev Community, I'll give a high-level overview of IRIS for people that are already familiar with the other databases such as Oracle, SQL Server, Snowflake, PostgeSQL, etc. I hope I can make things clearer and simpler for you and save you some time getting started.

In the modern world, the most valuable asset for companies is their data. Everything from business processes and applications to transactions is based on data which defines the success of the organization's operations, analysis, and decisions. In this scenario, the data structures need to be ready for frequent changes, yet in a managed and governed way. Otherwise, we will inevitably lose money, time, and quality of corporate solutions.

Dates with InterSystems

Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:

  1. Converting between internal and ODBC formats.
  2. Converting between local time, UTC, and Posix time.
  3. Converting to and from various date display formats.

Introduction

InterSystems IRIS allows you to build REST APIs using ObjectScript classes and the %CSP.REST framework. This enables the development of modern services to expose data for web apps, mobile apps, or system integrations.

In this article, you'll learn how to create a basic REST API in InterSystems IRIS, including:

This article describes a significant enhancement of how InterSystems IRIS deals with table statistics, a crucial element for IRIS SQL processing, in the 2025.2 release. We'll start with a brief refresher on what table statistics are, how they are used, and why we needed this enhancement. Then, we'll dive into the details of the new infrastructure for collecting and saving table statistics, after which we'll zoom in onto what the change means in practice for your applications. We'll end with a few additional notes on patterns enabled by the new model, and look forward to the follow-on phases of this initial delivery.

Hello, good morning, thank you so much for reading this question. ☺️🙂👍

We are developing a code to get information about our Production's items: services, processes and operations.

We know we can get various configurations of a given item: Category, Port, Enabled...

But we wonder how we could get the date time of the last mesage (most recent) received in an item.

To give a code snippet a small section of the code we have developed (and tested), it looks like:

How do I write DDL script for collection properties?

For example I want to create the following class:

Class SQLUser.Person {

Property Name As %String;

Property FavoriteColors As list Of %String;

}

My DDL script looks like this:

CREATE TABLE Person (Name varchar(50), FavoriteColors ???)

If you're migrating from Oracle to InterSystems IRIS—like many of my customers—you may run into Oracle-specific SQL patterns that need translation.

Take this example:

SELECT (TO_DATE('2023-05-12','YYYY-MM-DD') - LEVEL + 1) AS gap_date
FROM dual
CONNECT BY LEVEL <= (TO_DATE('2023-05-12','YYYY-MM-DD') - TO_DATE('2023-05-02','YYYY-MM-DD') + 1);

In Oracle:

Does anyone have a query that I could run to show a Vendor the time difference between when a message was sent out a BO, and when we received the HL7 ACK back that is associated with the message sent?

I am trying to prove to this vendor of the delay we are seeing getting the ACK back because of a Timeout

I know how to pull Ens.MessageHeader, and EnsLib.HL7.Message but not sure how to match up the Message with the HL7 Acknowledgement received.
