#SQL

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

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

Hope this ignites some interest.

Many thanks to:

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.

Creating a new virtual environment

mkdir chainsql

cd chainsql

python -m venv .

This applies to embedded and dynamic SQL queries in Caché ObjectScript. If I attempt to terminate the process via Management Portal, nothing happens. Neither does Ctrl C nor closing the terminal window in which my program is running, nor setting a stop flag in a global which is read by the program on each loop iteration. The only way to stop the query appears to be restarting the Caché server (which is running locally on my PC).

I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. I am having trouble with a specific table. When I need to query this specific table for specific fields, I am receiving an error. However, if I change the call to get all columns (`*`), there is no error. I get 37K records returned.

Error:

PHP Fatal error:  Uncaught PDOException: SQLSTATE[SL009]: <<Unknown error>>: [unixODBC][Driver Manager]No columns were bound prior to calling SQLFetch or SQLFetchScroll (SQLFetchScroll[0] at /builddir/build/BUILD/php-8.1.

Following the documentation to insert into tableA from tableB in the SQL query box from the Management Portal :

INSERT INTO tableA (col1, col2)
SELECT col1, col2
FROM tableB

This straightforward query raises the following error :

Error #5475: routine compilation error : %sqlcq.TESTuNAMESPACE.cls305. Errors: %sqlcq.TESTuNAMESPACE.cls305.cls
ERROR: %sqlcq.TESTuNAMESPACE.csl305.1(14) :
parseExtFrom+19^%qaqcmx
*mt("f", "1^TABLEA") :

Could someone help me decipher this error message ? Thanks for your help.

For the upcoming Python contest, I would like to make a small demo, on how to create a simple REST application using Python, which will use IRIS as a database. Using this tools

• FastAPI framework, high performance, easy to learn, fast to code, ready for production
• SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL
• Alembic is a lightweight database migration tool for usage with the SQLAlchemy Database Toolkit for Python.
• Uvicorn is an ASGI web server implementation for Python.

Hello Community,

I have couple of question about the DynamicSQL.

1. The %ObjectSelectMode is working perfectly in the DynamicSQL for the object property in direct query. However this is not supported for class query. Is there any way to resolve this / Get the object value for class query result.

2. What is the reason behind for a stored query prepared using %PrepareClassQuery() you must use the %Get("fieldname") method.

Class Samples.DB.NewClass1 Extends %Persistent
{
Property Address As NewClass3;
ClassMethod TestQuery()
{ 
	set statement = ##class(%SQL.Statement).%New()
	set statement.

Hi Community,

In this article, I listed 5 useful SQL functions with explanations and query examples 👇🏻
These 5 functions are

• COALESCE
• RANK
• DENSE_RANK
• ROW_NUMBER
• Function to Get Running Totals

So Let us start with COALESCE function

I have run the query and got ORU^R03 message from SQL Editor and reprocessed the message, But pdf not opened and the base64 content looks truncated.

Is there a way to get full content from the message from query? Why the content is not visible in DB that I can see in Message Viewer?

Thank you so much for your time to read this,

Hello My Friend,

I have a problem when I Query to get the data from SQL

Here's my code

Hey Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ InterSystems Cloud Services - InterSystems IRIS SQL & IntegratedML @ Global Summit 2023

The related package avoids adding %JSONAdaptor to each class but uses  instead   
SQL functions JSON_OBJECT() to create my JSON objects. With this approach, you can   
add JSON to any class - even deployed ones - without any need for change or recompiling.

The trigger was the Export of M:N relationships  as JSON  objects or arrays.

I need to run a SQL query and use the output to map PV1 7.1. The query is :

SELECT ID
FROM TestTable
WHERE ProviderName = 'TEST,PROVIDER' AND IDType= 'BPI'

When I run this query with the 'TEST PROVIDER'  I do pull the ID in question but I can't figure out how to do it from the DTL given that there are various providers sent in PV 1 7 . Any assistance will be greatly appreciated. 

Hi,

I am trying to find out individual segment values in Message viewer and it display the values in Management portal, copied the query and run it on SQL editor, Segment values displayed with blank. Is there a way to get the individual segment values using query?

I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. This works well most of the time, but when I query a table to get data from particular fields that contain long text strings, it returns `NULL`. These fields are all `VARCHAR(30000)`.

I tried using the `$extract` functionality in the IRIS documentation, but that made no difference. I also tried setting the PHP setting `odbc.defaultlrl` to both 31K and 0. Neither resolved the issue.

InterSystems FAQ rubric

It can be retrieved using the schema INFORMATION_SCHEMA.

INFORMATION_SCHEMA is a system schema and is not displayed by default in the SQL menu of the Management Portal.

The method to display it is as follows.

1. Open Management Portal → System Explorer → SQL menu.
2. Check "System" on the left of the schema drop-down.
3. Select INFORMATION_SCHEMA from the schema dropdown.

The SQL to get the ID, field name (COLUMN_NAME), data type (DATA_TYPE), description (DESCRIPTION) for the specified table (Sample.Human) is as follows.

 If you're looking to get started with SQL in InterSystems IRIS or want to make your queries more efficient, try one of these short online learning exercises!

• Running Fast Queries with SQL in InterSystems IRIS (10m)
• Optimizing SQL Queries in InterSystems IRIS (15m)

Both include learning labs, so no need to bring your own instance. 

Currently, the SQL privileges (SELECT, INSERT, UPDATE, DELETE) are managed at the tables level, which can be very tedious when you have to administer many roles in an organization, and need to keep them sync with a constantly evolving data models.
By managing privileges at the schemas level, will allow to give SELECT and other DML privileges to *all* or *several schemas* to a role|user, fixing the need to manually synchronize the new tables|views to the roles.

If you agree, I invite you to vote for this idea.

In today's landscape, enterprises have grown substantially in scale, amassing vast amounts of data. This data is collected from a plethora of sources including different applications, databases, and other channels. Given the diversity and volume of this data, it's only logical for these enterprises to seek a deeper understanding of what their data entails. Some of the data can be stored in IRIS, and it can be reasonable to be able to add this data to a data lake too.

The Internet now offers many different tools for such tasks, that do not yet support IRIS, but it's achievable.

Hi all,
I am trying to execute a query like the below code.
set statement = ##class(%ResultSet).%New("some_class:query_method").   // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

Hi developers,

We have received quite a lot of interest in using SQL on FHIR data. As you know, FHIR data is encoded in the form of a complex directed graph, and thus you can not easily query it with traditional SQL queries or business intelligence tools. Some customers have noticed that the "FHIR search tables" in IRIS for Health have flattened part of the FHIR graph, and have tried to use them for analytics. This is an undocumented and unsupported part of IRIS for Health, and can change without notice.
