Hello Community,

I'm executing the same query with same column name but in different case. An unique cached query generated while query executed first time. The query preparser only normalize the keywords and send to the SQL engine generates the Hash. Eventually use the cached query next use.

Now my question, The hash values are same for both of the queries. Then why it creates two cached queries.

Query1: select * from MyLearn.Test where Name['Kev1'

Query2: select * from MyLearn.Test where NamE['Kev1'

Hello developers,

In this article, I'll show you how to run code at compile time with ObjectScript macros.

Here's a use case that recently led me to use this feature:

As part of a medical application developed for more than 20 years, we have a large number of parameters. Although we have procedures for documenting these settings, it can be helpful to have a quick view of which settings are actually used by the application code.

When there's a performance issue, whether for all users on the system or a single process, the shortest path to understanding the root cause is usually to understand what the processes in question are spending their time doing. Are they mostly using CPU to dutifully march through their algorithm (for better or worse); or are they mostly reading database blocks from disk; or mostly waiting for something else, like LOCKs, ECP or database block collisions?

Hi,

I have a spring-boot Java application which has Quartz Scheduler (spring-boot-quartz-starter) dependency, and uses IRIS DB.
There is a problem with making Quartz Scheduler work with IRIS since there is a blob field expected in two tables, but IRIS is using longvarbinary type.
Can you provide me with clues on how to resolve this?

I am using org.quartz.impl.jdbcjobstore.StdJDBCDelegate driverDelegateClass.

This is the error:
MisfireHandler: Error handling misfires: Couldn't retrieve trigger: invalid stream header: 41434544

Hello,

Our team is working on building dashboard for internal reference and monitoring.

We would like to have details like Interface Name, Current Status, Last Messages Processed at, IP & Port, Serve/Instance/Production Environment name etc.

If there is any built-in service which we can utilize or any pre-compiled code that we can utilize to build such dashboard.

At this moment want to keep it basic, but moving forward will enhance with more advance features.

Please suggest, any help will be appreciated.

Thanks,

Yash

In this article, I am demonstrating how to create a table column(formerly known as properties) with your custom datatype classes by using User defined DDL. Properties are the crucial member of the persistent class definition. Datatypes are essential to define types of values that are stored in a table column. In general, the datatype names of SQL different from Intersystems datatypes, such as VARCHAR = %String.

Why should you connect Flask to InterSystems IRIS?

The first thing that comes to mind when we think about combining Flask with IRIS is a portal to interact with your clients and partners. A good example would be a website for patients to access their clinical exams. Of course, this case would require a whole new layer of security, which we did not cover in our last article. However, we can effortlessly add it with Werkzeug, for instance.

I have been walking through this with a few team members and as such I thought there might be others out there who could use it, especially if you work with HL7 & Ensemble/HealthConnect/HealthShare and never venture out past the Interoperability section.
