#SQL

InterSystems is pleased to announce the General Availability of InterSystems IRIS Cloud SQL and InterSystems IRIS Cloud IntegratedML, two foundational services for developing cloud-native solutions powered by the proven, enterprise-class performance and reliability of InterSystems IRIS technology. 

InterSystems IRIS Cloud SQL is a fully managed cloud service that brings the power of InterSystems IRIS relational database capabilities used by thousands of enterprise customers to a broad audience of application developers and data professionals.

HI *,

So last night I was doing a deployment which had a query to select from a large dataset of joined tables, to iterate through and populate data in a new table.

This was done in a classmethod using embedded SQL and the %PARALLEL keyword.
On a testing environment with the same dataset, this worked perfectly a few days earlier.

It was going to be a long-running process, so we started it from a csession using the JOB command.
Then get the PID with $zchild, go to Processes and monitor it there.
It would terminate after a minute or so with a <STORE> error.
The per process memory is set at 1GB.

Is it planned that LOAD DATA takes into account several DATE/DATETIME formats with, for example, a parameter indicating the format used in the source data?

example :

LOAD DATA .../...
USING
{
  "from": {
    "file": {
       "dateformat": "DD/MM/YYYY"
    }
  }
}

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!

Hello Community,

When using an SQL type Business Service, it may happen that we need to replay certain rows from the source table.

Let's take as an example the Business Service "from customer SQL" using the generic class EnsLib.SQL.Service.GenericService

Different cases arise, depending on the settings used on this Business Service.

First case :

If the Business Service only uses a KeyFieldName

In this case, to reprocess IDs 123, 456 and 789, it will be enough to delete them from the global ^Ens.AppData for the Business Service concerned on the "adaptor.sqlrow" reference:

kill ^Ens.

The forth in the trilogy, anyone a Hitchhikers Guide to the Galaxy fan?

If you are looking to breathe new life into an old MUMPS application follow these steps to map your globals to classes and expose all that beautiful data to Objects and SQL.

Hi,

I'm trying to access to my datas stored in a RecordMap from SQLAlchemy, and I need to access to any tables already created before using SQLAlchemy.

Here is some part of my code :

TestBase:

class TestBase(DeclarativeBase):
    CreatedAt: Mapped[int] = mapped_column(TIMESTAMP, default=func.now())
    UpdatedAt: Mapped[int] = mapped_column(TIMESTAMP, default=func.now(), onupdate=func.current_timestamp())

Engine creation and entities binding :

bases = {
    "TEST": TestBase.metadata.

Hello Community,

Generally we could insert the stream object through SQL for stream properties and insert the list values for list of %String property. So, Is there any way to achieve this insert for the list of objects property( ex: Property CodeTable As list of Sample.CodeTable) via SQL? 

Mapping Examples

Clearly if you have a fourth article in the trilogy you need to go for the money grab and write the fifth, so here it is!

Note:  Many years ago Dan Shusman told me that mapping globals is an art form.  There is no right or wrong way of doing it.  The way you interpret the data leads you to the type of mapping you do.  As always there is more than one way to get to a final answer.  As you look through my samples you will see there are some examples that map the same type of data in different ways.

Dear Community,

i need help to access to a Global like ^name over ODBC (SQL)
i will visit this global in a loop from a php site. It a access over SQL or ODBC possible?

Thanks for help and marry Christmas

Hi,

The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time. 

It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.

Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.

All the selects on the processes run at IsolationMode 0 and the transactions are kept as short as possible.

Hello!

I wonder how to select a conditional value from a Table column that has lists of values?
Example: I have a table in the database that looks like below:

For example, I want to know which Itemname it is for number 10 that is in the IDList. What should this SQL syntax look like? I have tried %INLIST and other things but only get blank value. How should the SQL-syntax for that query look like?

Greatful for all tips.
Regards,
Michael

IRIS External Table is an InterSystems Community Open Source Project, that allows you to use files, stored in the local file system and cloud object storage such as AWS S3 as SQL Tables.

It can be found on Github https://github.com/intersystems-community/IRIS-ExternalTable Open Exchange https://openexchange.intersystems.com/package/IRIS-External-Table and is included in InterSystems Package Manager ZPM.

To instal External Table from GitHub use:

git clone https://github.com/antonum/IRIS-ExternalTable.git
iris session iris
USER>set sc = ##class(%SYSTEM.OBJ).

Hi folks, 

I made a solution (https://openexchange.intersystems.com/package/iris-pretty-gpt-1) and want to use it like 

CREATE FUNCTION ChatGpt(IN prompt VARCHAR)
RETURNS VARCHAR
PROCEDURE
LANGUAGE OBJECTSCRIPT
{
    return ##class(dc.irisprettygpt.main).prompt(prompt)
}


CREATE TABLE people (
name VARCHAR(255),
city VARCHAR(255),
age INT(11)
)


INSERT INTO people ChatGpt("Make a json file with 100 lines of structure [{'name':'%name%', 'age':'%age%', 'city':'%city%'}]")

I know that a FUNCTION can only return one result.

Hi,

        What is the alternative for INTERSECT in cache. I tried Intersect but not working.

Thanks for suggestions.

thanks

Built on Java, it goes beyond real-time messaging, leveraging IRIS and ChatGPT for an enhanced chat experience. Also, the name of the project references the cultural classic - Star Wars.

Building Application

Building our dynamic chat application involves a seamless integration of key components and technologies. Java serves as the heart that drives server-side logic and business operations.

Case description

Let’s imagine that you are a Python developer or have a well-trained team specialized in Python, but the deadline you got to analyze some data in IRIS is tight. Of course, InterSystems offers many tools for all kinds of analyses and treatments. However, in the given scenario, it is better to get the job done using the good old Pandas and leave the IRIS for another time.
    For the abovementioned situation and many other cases, you might want to fetch tables from IRIS to manage data outside InterSystems’ products.

Hi Developers,

Hi, Community!

This article is an overview of SQLAlchemy, so let's begin!

SQLAlchemy is the Python SQL toolkit that serves as a bridge between your Python code and the relational database system of your choice. Created by Michael Bayer, it is currently available as an open-source library under the MIT License. SQLAlchemy supports a wide range of database systems, including PostgreSQL, MySQL, SQLite, Oracle, and Microsoft SQL Server, making it versatile and adaptable to different project requirements.

The SQLAlchemy SQL Toolkit and Object Relational Mapper from a comprehensive set of tools for working with databases and Python. It has several distinct areas of functionality which you can use individually or in various combinations. The major components are illustrated below, with component dependencies organized into layers:

I want to connect the app to Cloud SQL but when I registered and created the deployment (trial) I got the error:

Did anybody face such an error?
During the creation of an account, there was a message like 'username is taken' but the account have been created anyway. Maybe it could cause this problem.
 

Hi,

DBA has asked me to configure a working Business Operation using a SQL.OutboundAdapter (connecting to external MSSQL server) to run as TRANSACTION ISOLATION LEVEL READ UNCOMMITTED.

I would like help with an example of how this is done.

Thanks

How can IRIS productions be deployed more quickly and with greater peace of mind?

The aim of interoperability productions is to enable you to connect systems in order to transform and route messages between them. To connect systems, you develop, configure, deploy and manage productions that integrate several software systems.

That’s what the InterSystems documentation on its reference website tells us, but what do you actually have to do to deploy a production ?

Productions can be composed to connect external systems to the IRIS Data Platform.

GmOwl is a solution that offers an organized and engaging learning platform. It was developed to cater to the increasing need, for learning tools providing a versatile quiz environment that meets users requirements.

The main objective of GmOwl is to deliver an user experience for individuals participating in quizzes while giving administrators comprehensive control, over content and user engagement.

GmOwl uses Java EE with MVC template, and the InterSystems IRIS database is used to store data. The InterSystems JDBC Driver is used to connect to the database.

This question originally appeared in the comments of the post: [Video] InterSystems IRIS FHIR SQL Builder: Sneak Peek
 

Any chance the FHIR SQL Builder process could be automated? It'll help to refresh the SQL table so it'll be up to date!

Thanks

When using INSERT OR UPDATE command, 

How does the command know if the row exists?

Hello Community

IRISTEMP database consumes more disk space and make the production instance down when running Bulk SQL queries (maybe other processes aswell)

Is setting up the "Maximum" size it resolves the problem?. Is this setting impacts the performance? 

What are the approaches to resolve it

sample screenshot

This article is a simple quick starter (what I did was) with SqlDatabaseChain.

Hope this ignites some interest.

Many thanks to:

sqlalchemy-iris author @Dmitry Konnov Maslennikov

Your project made this possible today.

The article script uses openai API so caution not to share table information and records externally, that you didn't intend to.

A local model could be plugged in , instead if needed.
