Not sure there are many that connect to MS SQL to execute queries, stored procedures, etc, but our Healthsystem has many different MS SQL based databases we use within the Interoperability environment for various reasons.
With the push to moving from on-prem to the Cloud we ran into some difficulties with our SQL Gateway connections and knowing how to config them to use Microsoft Entra for Active Directory Authentication.
The Certification Team of InterSystems Learning Services is currently developing an InterSystems ObjectScript Specialist certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.
I’m facing issues with replicating data from my Caché 2016 database to a PostgreSQL database. I need to handle around 300 data updates per minute, and whenever certain tables are modified, those changes must be reflected in other databases.
I need to use a context variable in my code block for the table to query. When I use :content.table, it does not work. When using the literal, it does. How do I get the :context to work?
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 have a little problem, I need to diplay the data based on input status (first time and after)
this is the data:
and this what I need to display
the notes become new because it is the first time that the data has been inputed, and it will become old if we have the data before (2nd data, 3rd data the notes will become old).
I tried executing the SQL JSON_TABLE query with large JSON string(more than 200000 characters) and I got the below error. I'm curious about this under the hood workflow and how does it reach reaches MAXSTRING.
Imagine the scene. You are working happily at Widgets Direct, the internet's premier retailer of Widgets and Widget Accessories. Your boss has some devastating news, some customers might not be fully happy with their widgets, and we need a helpdesk application to track these complaints. To makes things interesting, he wants this with a very small code footprint and challenges you to deliver an application in less than 150 lines of code using InterSystems IRIS. Is this even possible?
My team is currently developing guidance and best practices for the generation, storage, and deployment of TUNE TABLE statistics across development and production environments. With that in mind, we want to get an idea of what methods teams in the field have developed for handling this data. In particular, we’d like to know the following:
There are three things most important to any SQL performance conversation: Indices, TuneTable, and Show Plan. The attached PDFs includes historical presentations on these topics that cover the basics of these 3 things in one place. Our documentation provides more detail on these and other SQL Performance topics in the links below. The eLearning options reinforces several of these topics. In addition, there are several Developer Community articles which touch on SQL performance, and those relevant links are also listed.
There is a fair amount of repetition in the information listed below. The most important aspects of SQL performance to consider are:
The types of indices available
Using one index type over another
The information TuneTable gathers for a table and what it means to the Optimizer
How to read a Show Plan to better understand if a query is good or bad
I’m currently experimenting with the SQL Gateway Connection, CREATE FOREIGN SERVER, and the THROUGH command (IRIS Documentation). To speed up my tests, I’ve combined several DemoDataSets in a Docker container and would like to automate the creation of SQL Gateway Connections using code.
Earlier this year I announced availability of a VS Code extension for coding in ObjectScript, Embedded Python or SQL using the notebook paradigm popularized by Jupyter. Today I published a maintenance release to correct a "getting started" problem.
Here's a video of the installation steps from the extension's README:
I am attempting to create a Foreign Server/Table so I can pull some information in from MS SQL server via JDBC connection, but as soon as I create the Server/Table and logout the Foreign Server disappears.
CREATE FOREIGN SERVER Epic.Clarity
FOREIGN DATA WRAPPER JDBC CONNECTION 'MS-EpicClarity'
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:
I’m using EnsLib.SQL.OutboundAdapter in my InterSystems Ensemble operation to execute an insert statement in Sql Server Management Studio 20. While inline queries (e.g., constructing the query string with _ concatenation) work fine, I'm facing issues when trying to use parameterized queries.
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.
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.
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)
I am using a JDBC connection to MS SQL server to execute a stored procedure to select data and bring it into InterSystems as a EnsLib.SQL.Snapshot. I loop through the EnsLib.SQL.Snapshot using a while loop, but I also want to iterate through the Columns within that Row to do logic.
Is there a way to iterate through the Columns of the current Row of the EnsLib.SQL.Snapshot so I can apply logic/rules for further processing?
