FOREIGN TABLES is a rather fresh feature in IRIS (2023.?) So I was motivated to try something new by own hands. Documentation of Foreign Table from File is a good starting point. Also the related promotional video is fine to start with.
There is a Link Procedure Wizard option within the Management Portal (System > SQL >Wizards > Link Procedure) which I had reliability issues with so I decided to use this solution instead.
Pandas is not just a popular software library. It is a cornerstone in the Python data analysis landscape. Renowned for its simplicity and power, it offers a variety of data structures and functions that are instrumental in transforming the complexity of data preparation and analysis into a more manageable form. It is particularly relevant in such specialized environments as ObjectScript for Key Performance Indicators (KPIs) and reporting, especially within the framework of the InterSystems IRIS platform, a leading data management and analysis solution.
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.
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.
The Certification Team of InterSystems Learning Services is developing an InterSystems IRIS Developer Professional certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.
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.
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.
I was struggling with a procedure that was meant to receive a string and use it as a filter, I've found that since I want the procedure to do some data transformation and return a dataset, I needed to use objectScript language.
I've created the procedure using the SQL GUI in the portal, and everything works fine when calling the procedure from the SQL GUI but not through a JDBC connection here is the call "call spPatientOS('2024-04-07T12:35:32Z')"
I get the following error when I am trying to create a linked server connection via MS OLE DB Provider for ODBC Drivers in MS SQL Server Management Studio. The message I get is:
The OLE DB provider "MSDASQL" for linked server "IRIS" reported an error. The provider did not give any information about the error. Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "IRIS". (Framework Microsoft SqlClient Data Provider)
Building my tech. example provided me with a bunch of findings htt I want to share. The first vectors I touched appeared with text analysis and more than 200 dimensions. I have to confess that I feel well with Einstein's 4 dimensional world. 7 to 15 dimensions populating the String Theory are somewhat across the border. But 200 and more is definitely far beyond my mathematical horizon.
In this article, I will introduce my application iris-VectorLab along with step by step guide to performing vector operations.
IRIS-VectorLab is a web application that demonstrates the functionality of Vector Search with the help of embedded python. It leverages the functionality of the Python framework SentenceTransformers for state-of-the-art sentence embeddings.
Application Features
Text to Embeddings Translation.
VECTOR-typed Data Insertion.
View Vector Data
Perform Vector Search by using VECTOR_DOT_PRODUCT and VECTOR_COSINE functions.
Demonstrate the difference between normal and vector search
HuggingFace Text generation with the help of GPT2 LLM (Large Language Model) model and Hugging Face pipeline
This can be achieved by using the CSV() procedure of the %SQL.Util.Procedures class. Below is an example of usage code. (Assuming that the file test.csv is in c:\temp.)
I'm currently running into a very weird issue to where I am trying to connect with a 64 bit version of SQL Server Management Studio (SSMS) to a HealthShare instance. I have created a System DSN using the Drivers (image below) that were downloaded with the Client version of the install and I'm able to successfully connect using my credentials.
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?
Tring to Performing following script in IRIS but do not know how to format Date. Normally, I would use TO_DATE or TO_TIMESTAMP in the actual queue statement below, but since I'm using Prepared Statements, I do not know how to format date in 'values' that is being used in the %Execute. It generates errors. I'm updating an Oracle Database via a SQL JDBC Gateway Connection. Does anyone know how to pass in Dates?
The basic idea is to use Vectors in the mathematical sense. I used geographic coordinates. These are of course only 2-dimensional but much easier to follow as vectors in text analysis with >200 dimensions.

When I use Escape logic when inserting or updating Oracle Table I'm getting Max-Length exceeded error. With the original value the length is good but after I add Escape Logic, it causes value to be greater than max-length. The original value was "I visited O'Brien before heading out of town." and after added Escape logic it was "I visited O''Brien before heading out of town." Max-Length is 45.
INSERT INTO MyText
(text)
VALUES
('I visited O''Brien before heading out of town.')

For example, I have two timestamp values ('2024-04-01 10:00:00', '2024-04-01 11:30:30'). I would like to find the difference between these two timestamps, and I need the result in hours:minutes:seconds (hh:mm:ss) format.
Expected Output: 01:30:30
Note: I need an SQL query command. I should not use ClassMethod, Function, or Stored Procedure.
Could anyone please provide me with an SQL query for my question?
Using VECTOR_COSINE() in SQL query to perform a text similarity search on existing embeddings in a %VECTOR column.
Code is below.
Commented out sql query returns this error: SQLCODE: -29 Field 'NEW_EMBEDDING_STR' not found in the applicable tables^ SELECT TOP ? maxID , activity , outcome FROMMain .AITest ORDER BY VECTOR_COSINE ( new_embedding_str ,
Sql query as written returns ERROR #5002: ObjectScript error: <PYTHON EXCEPTION> *<class 'OSError'>: isc_stdout_write: PyArg_ParseTuple failed!
