In a customer project I was asked how you can keep track of database changes: Who changed what at which date and time. Goal was to track insert, update and delete for both SQL and object access.

This is the table that I created to keep the Change Log:

/// Changelog, keep track of changes to any table
Class ChangeLog.DB.ChangeLog Extends (%Persistent, %JSON.Adaptor)
{

/// Action 
Property Action As %String(%JSONFIELDNAME = "action", DISPLAYLIST = ",Create,Update,Delete", MAXLEN = 1, VALUELIST = ",0,1,2");

/// Classname of the %Persistent class
Property ClassName As %String(%JSONFIELDNAME = "t

Hi all! 

How can I get the ODBC drivers for IRIS 2024.1 if I am only using IRIS 2024.1 Community Edition? 
This page gives you the information: "The official location for customers to download the latest released and fully supported InterSystems IRIS driver packages is the WRC download site." My first thought on this is: Why does Intersystems make it so difficult for users to use their database? Why is the ‘official’ driver package hidden behind a login wall? Shouldn't Intersystems be happy if someone wants to work with their database, wants to connect?

Any Way: Community Edition users are di

To disable the timeout, set the query timeout to disabled in the DSN settings:

Windows Control Panel > Administrative Tools > Data Sources (ODBC) > System DSN configuration

If you check Disable query timeout, the timeout will be disabled.

If you want to change it on the application side, you can set it at the ODBC API level.

Set the SQL_ATTR_QUERY_TIMEOUT attribute when calling the ODBC SQLSetStmtAttr function before connecting to the data source.

We have a yummy dataset with recipes written by multiple Reddit users, however most of the information is free text as the title or description of a post. Let's find out how we can very easily load the dataset, extract some features and analyze it using features from OpenAI large language model within Embedded Python and the Langchain framework.

Loading the dataset

First things first, we need to load the dataset or can we just connect to it?

There are different ways you can achieve this: for instance CSV Record Mapper you can use in an interoperability production or even nice OpenExchange appl

Hi Community,
In this series of articles, we will explore the following InterSystems SQL usage options:

1. Embedded SQL

2. Dynamic SQL

3. Class Queries

SQL Overview

InterSystems SQL provides a full set of standard relational features, including the ability to define table schema, execute queries, and define and execute stored procedures. You can execute InterSystems SQL interactively from the Management Portal or programmatically from using a SQL shell interface. Embedded SQL enables you to embed SQL statements in your ObjectScript code, while Dynamic SQL enables you to execute dynami

In the previous article, we saw in detail about Connectors, that let user upload their file and get it converted into embeddings and store it to IRIS DB. In this article, we'll explore different retrieval options that IRIS AI Studio offers - Semantic Search, Chat, Recommender and Similarity.

Hi guys,

I'm trying find a way to create a row with the number of each row.

For example:

In the SQL above, i want a way to create a collum with the number of corresponding row, in this case:

1

2

3

In SQl SERVER i can use FOR, RANK or ROM_NUMBER to do this, but, i can't find a way to do the same in cache SQL.

Can someone help me?

Thank you.

Geographic use of vector search

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.

The example loads a list of worldwide capitals with their coordinates
The coordinates are interpreted as vectors from geographic point 0°N/0 W
(some very wet spot in the Gulf of Guinea, >400 km from the African Coast)
Finding common directions from that spot is a quite theoretical case.
So adjustment to your preferred starting point is implemented.
Now finding simi

On IRIS version 2024.1.0.262.0 I have a table that store streams as %GlobalCharacterStream.
But depeding on the blob being saved I get the error: [Error: <<MAXSTRING>]

I had that with Caché, but to solve that I'd just enable the long strings on the page System Administration > Configuration > System Configuration > Memory and Startup > Enable Long Strings.
But for Iris I can't find that configuration, I looked on every config page from the portal and couldn't find it.

Btw this blobs are stored on Caché and the system using IRIS is reading from Caché and saving on IRIS.
Where, on IRIS, can I mak

Did you know that you can get JSON data directly from your SQL tables?

Let me introduce you to 2 useful SQL functions that are used to retrieve JSON data from SQL queries - JSON_ARRAY and JSON_OBJECT. 
You can use those functions in the SELECT statement with other types of select items, and they can be specified in other locations where an SQL function can be used, such as in a WHERE clause

The JSON_ARRAY function takes a comma-separated list of expressions and returns a JSON array containing those values.

SELECT TOP 3Name,
JSON_ARRAY(%ID,%TABLENAME,UCASE(Name),Age,Home_State) "JSON data" 

Technical surprises using VECTORs
>>> UPDATED

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.

Hello Community,

I'm executing the same query with same  column name but in different case. An unique cached query generated while query executed first time. The query preparser only normalize the keywords and send to the SQL engine generates the Hash. Eventually use the cached query next use.

Now my question, The hash values are same for both of the queries. Then why it creates two cached queries.

Query1: select * from MyLearn.Test where Name['Kev1'

Query2: select * from MyLearn.Test where NamE['Kev1'

The InterSystems IRIS has a series of facilitators to capture, persist, interoperate, and generate analytical information from data in XML format. This article will demonstrate how to do the following:

1. Capture XML (via a file in our example);
2. Process the data captured in interoperability;
3. Persist XML in persistent entities/tables;
4. Create analytical views for the captured XML data.

Capture XML data

The InterSystems IRIS has many built-in adapters to capture data, including the next ones:

1. File Adapter: used to get files from network folders.
2. FTP Adapter: employed to obtain files fr

Hi everyone.

I have a function that may end up being called from a number of transformations at the same time, and within the function there's some Embedded SQL to first check if a local table has an entry, and then adds the entry if it doesn't exist.

To prevent a race condition where the function is called by two transformations and they both end up attempting to insert the same value, I'm looking to use the table hint "WITH TABLOCK" on the insert, but this seems to be failing the syntax checks within vscode.

Are table hints supported with embedded sql?

If not, is there a way to prevent t

Hi,

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')"

the bottom line is that the procedure was created with the parameter defined as STRING(MAXLEN=1) which means that my parameter from the jdbc

Hey everyone,

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.

After I have my System DSN (image below) configured, I go into SSMS and add a Linked Server that is referencing the System DSN that was created. Also, I change the provider to be Microsoft OLE DB Provider for ODBC Drivers. I go into Secu

Hi,

I have created view from External table joins internal persistent table. Create VIEW worked but Select * from Viewxxx throwing error.

"References to an SQL connection must constitute a whole subquery"

Could it possible to create view with external db table with local persistant table and to access it?

please suggest any thoughts on it..

How to see a meaningful value in management portal - sql explorer. For instance
Class MySetting Extends %Persistent{
     Property Name As %String;

Class MyObj Extends %Persistent{
    Property Setting As MySetting;

When browsing MyObj in management portal (just select * from MyObj - lazy to do a join), I will see 1,2.. values in the Setting column. I would like to see the Name. I do not want index MySetting with Name as primary as the name can change

Thank for your comment.

Introduction

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.

Problem

You need to query an external SQL database to use the response within a namespace. This guide is assuming that you already have a working stored procedure in SSMS although you could instead use a SQL block within the operation. Stored procedures in SSMS are preferred to maintain integrity, Embedded SQL can get very confusing if you have a complicated SQL statement.

In this example, I

I am currently adding a field to our Existing messaging from Epic, however there might be a possibility I need to back load data into the Ancillary system. While I have the previous messages that can be sent, they do not have this additional field that I am adding to the message.

I can do a lookup against Epic Clarity SQL Database; however, I don't want to throw a wrench into the workflow if the system cannot connect to the Epic Clarity SQL Database.

• What is the best solution for this?
  • If I setup a linked view/database within IRIS does this guarantee that the information will be availab

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?
