Hello, I need to use IRIS to connect to an MSSQL base.
It has to be done via ODBC, I can't use JDBC at this time by client option.

I am trying to use Microsoft Driver
libmsodbcsql-13.1.so.9.2

But I can't, my attempts result in:
Connection failed.
SQLState: () NativeError: [11001] Message:

I have done all DSN configuration, and my configuration is listed in SQL Gateway Connections. I know it's working, because when I run a test with isql I have the information that connects to the bank.

Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:

1. Converting between internal and ODBC formats.
2. Converting between local time, UTC, and Posix time.
3. Converting to and from various date display formats.

In SQL, NULL data and the empty string ('') are different data. The method for setting and checking each is as follows.

(1) NULL data

Hi community members!

I'm testing some functionalities about Foreign Tables and it works smoothly with PostgreSQL database, but I found out an issue with MySQL database, I followed the documentation:

When running a sql insert query with CONVERT('datetime', '2023-12-12 11:27:00',120) in an insert statement into a table this works on one server and not the other.

i.e. to record datetimereceived

LS,

I'm executing a query using JDBC on a PostgreSQL db:

SET statement_timeout TO 600000000; COMMIT SELECT * FROM bi_hour

The query is aborted with the following message:

FOUT #5023: Fout in Java Gateway: JDBC Gateway getClob(0,2) errorBad value for type long : active

The column 'blocked_status' contains the value 'active' is of type 'text'. I figure somewhere the SQL Gateway tries to convert the text value into a long but I can't find where, any suggestions?

Suppose you have an application that allows users to write posts and comment on them. (Wait... that sounds familiar...)

For a given user, you want to be able to list all of the published posts with which that user has interacted - that is, either authored or commented on. How do you make this as fast as possible?

Here's what our %Persistent class definitions might look like as a starting point (storage definitions are important, but omitted for brevity):

In tracking down some of our Orphaned message issues, I was wondering if setting our EnsLib.SQL.Snapshot variable equal to "" was the same as calling the .Clean() method on EnsLib.SQL.Snapshot? Are they the same?

should I be possibly using ##class(EnsLib.SQL.Snapshot).%Delete() instead?

I implemented a Python Flask application for the 2024 Python Contest with a page that provides common form fields for an outgoing email such as the To and CC fields. And it lets you input a message as well as uploading text based attachments.

Then using LlamaIndex in Python, the app analyzes the content you put in and returns to you in a result box if there is anything that should stop you from sending that email.

Take a look at the Github repo here.

Hi Community,

In this article, I will introduce my application iris-RAG-Gen .

Iris-RAG-Gen is a generative AI Retrieval-Augmented Generation (RAG) application that leverages the functionality of IRIS Vector Search to personalize ChatGPT with the help of the Streamlit web framework, LangChain, and OpenAI. The application uses IRIS as a vector store.

Application Features

• Ingest Documents (PDF or TXT) into IRIS
• Chat with the selected Ingested document
• Delete Ingested Documents
• OpenAI ChatGPT

Hi all,

Some days ago, I've seen a youtuber talking about how to create a neural network (sorry, is in spanish)

Hello Community,

I'm unable see the FHIR SQL builder /csp/fhirsql and /csp/fhirsql/api/ui endpoints in web application to access the FHIR SQL builder. I'm using community edition 2024.1 and it contains the "FHIR SQL Builder".

Hello Community,

I've seen two cached queries are generated while executing a query. So, Why the additional query is generated and what is the use of it.
