I am accessing IRIS databases with JDBC (or ODBC) using Python. I want to fetch the data into a pandas dataframe to manipulate the data and create charts from it. I ran into a problem with string handling while using JDBC. This post is to help if anyone else has the same issues. Or, if there is an easier way to solve this, let me know in the comments!
I am using OSX, so I am unsure how unique my problem is. I am using Jupyter Notebooks, although the code would generally be the same if you used any other Python program or framework.
I encountered a strange issue I just can’t solve and I am running out of ideas. After reading the relevant passages of the documentation, asking the community is my last resort.
I am experiencing a problem with an EDI process that uses a SQL Batch Service to connect to our DEV environment. However, when we point the EDI service to our TEST server, it errors out.
I have checked every single property on our TEST and DEV servers as well as the properties on the associated tables. They are identical. Nothing has changed in the SQL either.
In the world of APIs, REST is very extended. But what happens when you need more flexibility in your data-fetching strategies? For instance letting the client to choose what fields is going to receive. Enter GraphQL, a query language for your APIs that provides a flexible alternative to REST.
In this post, we will:
Compare REST and GraphQL.
Dive into the basics of GraphQL: Queries, Mutations, and HTTP.
Build a simple GraphQL server implementation using Graphene, SQLAlchemy, and Flask over data in InterSystems IRIS.
Explore how to deploy your GraphQL server as a WSGI application in IRIS.
In the Inbound SQL Adapter settings, is it possible to specify more than 1 field as the Key Field Name?
Because of the way the Query is being index in Ensemble by the Key Field Name, sometimes transactions get missed and I would like to see if we can add an additional key to the mix to ensure all the transactions are picked up. In this case the InterfaceTrigger is an ID that is auto generated by the table, and I would like to use that as well to ensure we don't miss transactions, and it does not throw any warning messages when it executes the Delete Query.
In T-SQL, I can create a recursive CTE to create a subquery or a view that will hold a whole lot of numbers. Is there a way to do this in Cache SQL? I'd like the numbers from 0 to 10000 if possible.
Can anyone please help me how to use regular expression/wild character on a sql query for a pattern like C00.0 to C00.9, C01.0 to C01.9 and so on until C77.0 to C77.9 .
InterSystems IRIS has long supported the obvious translation functions required to for converting to upper or lowercase to enforce case-insensitive string comparison (e.g. in ObjectScript with $zconvert) and sorting (e.g. with SQL collation functions, not to be confused with NLS collation). Customers in international contexts have at times used custom workarounds to also treat accent insensitivity or even more advanced normalization duct tape. We’re looking to address such use cases at the system and SQL level to increase convenience for this international audience, which is well represented on the Developer Community.
The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time.
It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.
Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.

The main objective of GmOwl is to deliver an user experience for individuals participating in quizzes while giving administrators comprehensive control, over content and user engagement.
GmOwl uses Java EE with MVC template, and the InterSystems IRIS database is used to store data. The InterSystems JDBC Driver is used to connect to the database.
New to CSP and Zen. I've been going through tutorials and have made some progress. Using the "Contacts" tutorial as an example, I'm trying to create a "ViewContact" page. I want this to be linkable so I'm using URI Parameters, which I understand. However, what I'm not sure about is how to retrieve a specific record. Should I use a SQL statement? If so, how?
Last week at the InterSystems Global Summit, we announced our new Foreign Tables capability, which was introduced as an experimental feature with the 2023.1 release earlier this year.
I am trying to pinpoint and troubleshoot an issue we have been seeing lately. We have several SQL Outbound Adapter Operations that are seeing issues trying to connect to our MS SQL Servers using the JDBC Gateway for calling insert, select, update, and stored procedure calls.
SELECT '['||Material->Sifra||'] '||Material->Opis AS Material, SUM(MasaBlago) AS MasaBlago FROM Tehtanje.Dokument WHERE DatumDokumenta BETWEEN '01/01/2023' AND '04/01/2023' AND (Material->Sifra %INLIST $LISTFROMSTRING('5,7',',')) GROUP BY Material ORDER BY %EXACT Material
The query returns all rows where Material->Sifra is 5 or 7. That's OK.
If I want to get all rows where Material->Sifra is NOT 5 or 7 I use query:
Greetings community. I would like to know how to migrate a BD in production to a local environment. When I have a system in production (BD Sql Server) what we do is mount a local copy to do the analysis with the data and not occupy resources of the system in production. My question is: How do you do it with Intersystems technology?
I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. This works well most of the time, but when I query a table to get data from particular fields that contain long text strings, it returns `NULL`. These fields are all `VARCHAR(30000)`.
I have a ZEN page with nine tablepanes. Each tablepane queries a table in the same SQLServer db. I have a single SQLGateWay(odbc) to this SQLServer db. I need to get better performance when I query all nine table at the same time. Would my performance improve if I had nine SQLGateWays(nine odbc configurations/connections), one for each query? I would appreciate any and all suggestions for getting the very best performance when using SQLGateWays. Thank you.
A question has come up that I am not finding the answer for.... Does the daily purge process re-index EnsLib.HL7.SearchTable or other SQL tables? In looking at the purge process documentation I am not seeing anything that mentions EnsLib.HL7.SearchTable. Do we have to manually constantly re-index tables that we create? For example I created another search table based off of EnsLib.HL7.Search table, will I need to constantly watch this as it grows? How do tables get index, is there some kind of mechanism that automatically does it, or are we responsible for indexing tables ourselves?
