SQL is a standard language for storing, manipulating and retrieving data in relational databases.

I am currently experiencing frustration with trying to Authenticate an Active Directory account through JDBC as the Hospital System moves from OnPrem SQL Server to using Azure SQL Server with Microsoft Entra Authentication.

Microsoft cannot give me a straight answer of what is required from a JDBC standpoint to authenticate from a Linux environment.

Hi Everyone!

JSON Support in IRIS SQL

While working on getting JSON support for some Python libraries, I discovered some capabilities IRIS provided.

  • JSON_OBJECT - A conversion function that returns data as a JSON object.
  • JSON_ARRAY - A conversion function that returns data as a JSON array.
  • IS JSON - Determines if a data value is in JSON format.
  • JSON_TABLE function returns a table that can be used in a SQL query by mapping JSON.
  • JSONPath support - is a query language for querying values in JSON.

In this tutorial, I will discuss how can you connect your IRIS data platform to sql server db .

Hello,

So i want to use the INSERT OR UPDATE command so i can update a COUNTER for a given name:

INSERT OR UPDATE myTable
SET name='Omer', counter = counter + 1;


as you can see with the above code - if the row is non-existent then we get an error because COUNTER is NULL!
I tried the following to fix this but all have failed:

SQL injection remains one of the most critical vulnerabilities in database-driven applications, allowing attackers to manipulate queries and potentially access or compromise sensitive data. In InterSystems IRIS, developers have access to both Dynamic SQL and Embedded SQL, each with distinct characteristics. Understanding how to use them securely is essential for preventing SQL injection.

My IRIS instance is connected to a Postgres database using SQL Gateway and linked tables.
One of these tables is projected to the Patient class. I want to select a record from this table by ID and convert it to a FHIR resource using the %ExistsId and %OpenId methods.
I noticed that if I call these two methods from the console, the record is always found.

Like many others probably find themselves, we were stuck doing live data mapping in our Interface Engine that we really didn't want to do, but had no good alternative choice. We want to only keep mappings for as long as possibly needed and then purge expired rows based upon a TTL value. We actually had 4 use cases for it ourselves before we built this. Use cases:

Foreign Servers - Visibility?

First time trying to use Foreign Tables/Servers instead of Linked Tables...

Within the SQL Editor inside of the Managment Portal, or connecting through DBeaver JDBC how we can see what Foreign Servers have been defined? Is there a way to query and verify structure of the Foreign Server connection to know that we are building the correct Foreign Tables?

I attempted to create my first Foreign table but it failed when I tried to query the tables because it said the table could not be found. But when I sign into the Database via SQL Management Studio, I can see the table.

Hello My Friends,

I have a question how to use order by %DLIST, this is my code:

SELECT

$ListToString(%DLIST(DISTINCT MRDIA_ICDCode_DR->MRCID_Code),', ' ) ICDX,

$ListToString(%DLIST(DISTINCT (MRDIA_ICDCode_DR->MRCID_Desc || ' (' || MRDIA_DiagnosisType_DR->DTYP_Code || ')')),', ' ) Diagnose

FROM SQLUser.PA_Adm

LEFT JOIN SQLUser.PA_AdmInsurance ON (PAADM_RowID = INS_ParRef AND INS_Rank = 1)

LEFT JOIN SQLUser.PA_AdmPackage ON (PAADM_RowID = PACK_ParRef)

LEFT JOIN SQLUser.MR_Adm on MRADM_ADM_DR = PAADM_RowID

The rise of Big Data projects, real-time self-service analytics, online query services, and social networks, among others, have enabled scenarios for massive and high-performance data queries. In response to this challenge, MPP (massively parallel processing database) technology was created, and it quickly established itself. Among the open-source MPP options, Presto (https://prestodb.io/) is the best-known option. It originated in Facebook and was utilized for data analytics, but later became open-sourced.

Hence the question: is there a way to do that?

The goal is to get data (from half a thousand to 3-4 thousands lines) from DB, calculate standart deviation then use it as logical condition in analyzer.

For example IF std > custom_value = show_the_result ELSE null

There is a STDDEV(MDX) method used in Analyzer but it is a measure and it can not be used as logical condition (correct me if i am wrong)
