In this tutorial, I’d like to talk about Class Queries. To be more precise, about the Queries based on user-written code:

A lot of people disregard this type of query just because they aren’t very comfortable with writing lots of ObjectScript code for the methods or they don’t see how they can use it in their relational apps.But to be honest, for me – it’s one of the coolest inventions for the relational model in IRIS!It lets you expose whatever information you want (not limited to tables of your database) as a relational resultset for a client.

Hi,
just want to know if indexes in IRIS / SQL are autobuilding.

I define an index in a table and then i costantly do a lot of insert/delete in that table. Will i face index problem? Do i need to rebuild it often?

Thanks

In this article, we will establish an encrypted JDBC connection between Tableau Desktop and InterSystems IRIS database using a JDBC driver. While documentation on configuring TLS with Java clients covers all possible topics on establishing an encrypted JDBC connection, configuring it with Tableau might be a little bit tricky, so I decided to write it down.

Securing SuperServer

Before we start with client connections, you need to configure SuperServer, which by default runs on port 1972 and is responsible for xDBC traffic to accept encrypted connections. This topic is described in the documentati

Apache Superset is a modern data exploration and data visualization platform. Superset can replace or augment proprietary business intelligence tools for many teams. Superset integrates well with a variety of data sources.

And now it is possible to use with InterSystems IRIS as well.

An online demo is available and it uses IRIS Cloud SQL as a data source.

Hi Developers!

There is a recent update came for developer community images of InterSystems IRIS and IRIS For Health.

This release comes with Environment variables support.

Currently 3 variables are supported:

• IRIS_USERNAME=user to create
• IRIS_PASSWORD=with password
• IRIS_NAMESPACE=create namespace if doesn't exist

Here is what you can do - see below.

Start iris with your username and password created:

docker run --rm --name iris-sql -d -p 9091:1972 -p 9092:52773  -e IRIS_PASSWORD=demo -e IRIS_USERNAME=demo intersystemsdc/iris-community

Hi Developers!

Here is the score of technical bonuses for participants' applications in the InterSystems Developer Tools Contest 2023!

We have a rule to disable a user account if they have not logged in for a certain number of days. IRIS Audit database logs many events such as login failures for example. It can be configured to log successful logins as well. We have IRIS clusters with many IRIS instances. I like to run queries against audit data from ALL IRIS instances and identify user accounts which have not logged into ANY IRIS instance.

Instead of running queries against many IRIS instances, I developed audit-consolidator to consolidate audit data from many IRIS instances into ONE database table to run queries against the

Here're the technology bonuses for the InterSystems IRIS Cloud SQL and IntegratedML Contest 2023 that will give you extra points in the voting:

• IntegratedML usage
• Online Demo
• Article on Developer Community
• The second article on Developer Community
• Video on YouTube

Within IRIS I defined a task to export audit data every day.

I provide some sample files in my GitHub repo.

I wrote ObjectScript code to import all files into otw.audit.consolidator class.

I want to use Python SQLAlchemy, pandas and sqlalchemy-iris (created by Dmitry Maslenikov) to copy consolidated audit data from my consolidator class in my IRIS container to my InterSystems Cloud SQL deployment.

I updated my Dockerfile to pip3 install sqlalchemy-iris and pandas (dataframes).

docker-compose build –no-cache in my personal AWS took 700 seconds.

Hi Community,
In this article, I will introduce my application iris-mlm-explainer

This web application connects to InterSystems Cloud SQL to create, train, validate, and predict ML models, make Predictions and display a dashboard of all the trained models with an explanation of the workings of a fitted machine learning model. The dashboard provides interactive plots on model performance, feature importances, feature contributions to individual predictions, partial dependence plots, SHAP (interaction) values, visualization of individual decision trees, etc.

Hi all,

I'm trying to use LOAD DATA to insert 11k (11,377) rows of data. LOAD BULK DATA is not available for the version of IRIS I am using.

After calling LOAD DATA it says only 5,500 rows has been inserted. The LOAD DATA docs says any error rows are skipped and a count of skipped rows can be found in %SQL_Diag.Result however there are no results here. There are no errors in the xDBC error log either.

Why have over half the rows been skipped?

In the vast and varied SQL database market, InterSystems IRIS stands out as a platform that goes way beyond just SQL, offering a seamless multimodel experience and supporting a rich set of development paradigms. Especially the advanced Object-Relational engine has helped organizations use the best-fit development approach for each facet of their data-intensive workloads, for example ingesting data through Objects and simultaneously querying it through SQL. Persistent Classes correspond to SQL tables, their properties to table columns and business logic is easily accessed using User-Defined Functions or Stored Procedures. In this article, we'll zoom in on a little bit of the magic just below the surface, and discuss how it may affect your development and deployment practices. This is an area of the product where we have plans to evolve and improve, so please don't hesitate to share your views and experiences using the comments section below.

Assuming I have an SQL table with data, is it possible to get DML export (INSERT statements for this data)?

InterSystems FAQ rubric

The ID of the last updated record can be obtained using the SQL function LAST_IDENTITY().
* This function can be used with embedded SQL or ODBC but not with Dynamic SQL, SQL Shell, or the Management Portal's SQL interface.

Here's an example of usage with simple Embedded SQL:

looking into tenants  I see this:

But on the main page, I have 2 deployments that I can work with  !! 

What is going on ??

I have  an accepted tenant and want to share my deployment.

how is this possible?

On an IRIS system, we expect the default string collation for SQL columns to be SQLUPPER. This means WHERE conditions will be case-insensitive. However, when I make a WHERE condition on a SQL procedure that returns a string, it's case sensitive.For example:

Class Sample.Person Extends%Persistent
{

Property Name As%String;ClassMethod Test() As%String [ SqlProc ]
{
    return"Abe Lincoln"
}

} 

If I query select * from Sample.Person where Name = 'abe lincoln', it will return results where name = "Abe Lincoln". If I query select * from Sample.Person where Sample.Person_Test() = 'abe

Hi developers!

What is the way using SQL to list all the tables available in the current database/namespace?

Hi.

I have a query:

SELECT '['||Material->Sifra||'] '||Material->Opis AS Material,
       SUM(MasaBlago) AS MasaBlago
 FROM Tehtanje.Dokument
 WHERE DatumDokumenta BETWEEN '01/01/2023' AND '04/01/2023'
 AND (Material->Sifra %INLIST $LISTFROMSTRING('5,7',','))
 GROUP BY Material
 ORDER BY %EXACT Material

The query returns all rows where Material->Sifra is 5 or 7. That's OK.

If I want to get all rows where Material->Sifra is NOT 5 or 7 I use query:

SELECT '['||Material->Sifra||'] '||Material->Opis AS Material,
       SUM(MasaBlago) AS MasaBlago
 FROM Tehtanje.Dokument
 WHERE DatumDokumenta BETWEEN

Most of the databases with SQL access offers the DATE_TRUNC function or analogs. This helps to easily truncate a date by any part while keeping the DateTime in a valid format

In some testing scenarios, I need to clone the database. While I use only SQL access.

I need all data to be cloned, not mapped from the original database, and a separate database to be accessed.

Is there any way to do so?

Something like

CREATEDATABASE [Databasetocreate]
WITHTEMPLATE [Databaseto copy]

In the documentation  Data Types | Caché SQL Reference | Caché & Ensemble 2018.1.4 – 2018.1.8 (intersystems.com)

it says that "by default, Caché establishes a system-wide ODBC VARCHAR maximum length of 4096; this ODBC maximum length is configurable"

Per instructions, I went to SMP -> System -> Configuration -> General SQL Settings, where most of the fields from  $SYSTEM.SQL.CurrentSettings()

appear. That one does not.

How does one change it, and can it be increased?

Thanks!
