How to query BLOB type data in MYSQL database through JDBC or ODBC

Need to make ODBC connection to fetch data from SQL Server to IRIS 2021.1. Once we are able to query the data from SQL server, need to Pass it in ensemble production

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.')
                 /\
             right here  

Any ideas around this?

Hi, what is the easiest way to clear all the tables which store FHIR data? The most straitforward approach is to get a list of tables using the information_schema.tables view, then execute dynamic SQL with the "delete from" clause, but perhaps some helper class has already been written for this purpose?

Hello everyone,

I am looking for the syntax or the way to use a class created in the "BNA" Namespace (my application) from the %SYS Namespace.

Here is the context:

I have a "BNA" application contained in the "BNA" NS, this application provides a user creation functionality. This feature creates both the user in a table in the application and in the Iris system.

Hi VSCode users!

Just want to check with you, is this settings.json file ideal enough if I:

1. Want VSCode to connect to IRIS in docker?

2. Want to use VSCode SQL Tool?

Hi All,

On February 8, 2024, we asked for input from the IRIS community regarding exam topics for our InterSystems IRIS Developer Professional exam. We will close the window for providing feedback on the exam topics on Friday, March 8, 2024. If you would like to have your say in what topics are covered on the exam, this is your last chance!

How can I access the survey? You can access it here

There is an interesting new feature in the recently announced 2024.1 preview, JSON_TABLE. JSON_TABLE is one of a family of functions introduced by the 2016 version of the SQL Standard (ISO Standard, published in early 2017). It allows for JSON values to be mapped to columns and queried using SQL. JSON_TABLE is valid in the FROM clause of some SQL statements.

The syntax of JSON_TABLE is quite large, allowing for exceptional conditions where the provided JSON values don't match expectations, nested structures and so on.

Need to fetch data from SQL server management studio to ensemble, using jdbc or ODBC. 

Step by step solution would be highly appreciated. 

Nowadays so much noise around LLM, AI, and so on. Vector databases are kind of a part of it, and already many different realizations for the support in the world outside of IRIS. 

Why Vector?

• Similarity Search: Vectors allow for efficient similarity search, such as finding the most similar items or documents in a dataset. Traditional relational databases are designed for exact match searches, which are not suitable for tasks like image or text similarity search.
• Flexibility: Vector representations are versatile and can be derived from various data types, such as text (via embeddings like Word2Vec, BERT), images (via deep learning models), and more.
• Cross-Modal Searches: Vectors enable searching across different data modalities. For instance, given a vector representation of an image, one can search for similar images or related texts in a multimodal database.

And many other reasons.

So, for this pyhon contest, I decided to try to implement this support. And unfortunately I did not manage to finish it in time, below I'll explain why.

Hello Everyone,

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.

Note: This exam will replace the current InterSystems IRIS Core Solutions Developer Specialist exam when it is released. Please note from the target role description below that the focus of the new exam will be more on developer best practices and a lot less on the ObjectScript programming language.

Hello Community,

SQL language remains the most practical way to retrieve information stored in a database.

The JSON format is very often used in data exchange.

It is therefore common to seek to obtain data in JSON format from SQL queries.

Below you will find simple examples that can help you meet this need using ObjectScript and Python code.

ObjectScript : using Dynamic SQL with %SQL.Statement +  JSON structures with %DynamicObject and %DynamicArray

In this article I will demonstrate the following :

• Update ReferencesRange(OBX:7) against ObservationIdentifier(OBX:3.1)[TestCode] from database by using custom utility function
• Update Abnormal Flag(OBX:8) against ObservationIdentifier(OBX:3.1)[TestCode]  and ObservationValue(OBX:5)[Result] from database utility function
• Route Message based on Abnormal Flag(OBX:8)

I have tried various directories, including a system level directory. I tried creating the file before I do the export in case there was an issue with creating the files, and I also made sure the created files had rwe permisisons.No matter what I do, it never creates

Is it possible to authenticate an xDBC (ODBC/JDBC) connection to InterSystems IRIS via (a 3rd party) OAuth server?

For REST APIs this is possible, but could this be achieved with OAuth? 

Out-of-the-box the ODBC/JDBC Drivers don't seem to have this option, but maybe some custom code could enable this? perhaps via Delegated Authentication and some OAuth classes customization, or some other way?

Has anyone done this already and can share how it was implemented, or someone with some guideline suggestions?

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? 

Books Table definition

Wondering what version the Information.Schema schema was introduced, so that I can decide how to query the metadata for user defined tables. 

Thank you!

I am trying to do a INSERT OR UPDATE SQL query, but the query always inserts new rows to table. Is it how I defined the table or am I mising something in the query?

table defines as,

{

Property Tablespace As %Library.String(MAXLEN = 50) [ SqlColumnNumber = 2 ];

Property DepartmentId As %Library.String(MAXLEN = 50) [ SqlColumnNumber = 3 ];

Property TimezoneName As %Library.String(MAXLEN = 100) [ SqlColumnNumber = 4 ];

Property PatientDepartmentName As %Library.String(MAXLEN = 100) [ SqlColumnNumber = 5 ];

I'm not sure how to interpret the error.

⏯ Working with InterSystems IRIS Cloud SQL

Hi Community,

I am attempting to create a new table by executing a SELECT statement that involves joining multiple tables. However, I encountered an error during execution: '( expected, AS found^Combined AS.' I would also like to create a cube based on this SQL table. However, during the cube creation process, I am prompted to specify a source class, and I'm unsure which class to use as it requires an existing class. Could you please help me identify the issue with the table creation, and provide guidance on selecting the appropriate source class for the cube creation?"

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. 

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.

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.

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:
