#JDBC

Hi team,

I'll start with an apology as I am trying to wrap my head around the architecture of how InterSystems IRIS database management works. I am attempting to connect to the platform remotely through say a JDBC or ODBC connection in order to run queries, searches (through SQL statements) on my laptop and was trying to understand whether this would be possible? It is possible to setup an inbound client connection and wanted to better understand the architecture of how the database association works for IRIS database management. Does it use it's own internal SQL database or are we able to connect to our own database and which databases are certified to run against the platform?

I am under the impression that inside HealthShare you can Services, Processes, and Operations. The service takes incoming data, the processes can process that data, and then the operations can send that data out.

I am curious if anyone has any experience, guides, or advice on how I can send data to a service using a Java application. I intend for the data to be in XML format. I am also curious if I succeed at picking up the data in the service, how I send the data back to the Java application using an Operation.

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

One of our apps uses a class query to support a ZEN Report and works just fine in that report, producing the expected results every time. We’ve since migrated to InterSystems Reports and noticed that, for a report using the same class query, 100s of extra rows with the same column values appear at its bottom.

Problems with Strings

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.

GmOwl is a solution that offers an organized and engaging learning platform. It was developed to cater to the increasing need, for learning tools providing a versatile quiz environment that meets users requirements.

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.

Hi all...

I am try to execute a class method from JDBC connection. My method are simple, just create a file at $HOME like this:

set sc='$zf(-1,"touch $HOME/lixo.txt > /var/tmp/log666 2>&1")

I put a log file to this commnad because it's don't work, and in log file i get this:

touch: cannot touch ‘/root/lixo.txt’: Permission denied

after to try other commands I found that user and enviromnent variables are diferents:
I try this:

Hi, I asked last week and they gave me some little tips. But the truth is I still can't carry out this "Project".

I must perform a REST service, using Oracle 11 database. Eh tried anyway to achieve this.

The purpose is to make a REST service, using the database provided to me and use the procedure that is already created.

According to what I read, I made the connection via JDBC and I had no major problem

Hello,

I work on deploying IRIS using Kubernetes operator and Red Hat OpenShift. I encouraged another team working on Java application to consider using IRIS as database. My team deployed IRIS cluster using two mirrored data pods for the other team. The other team asked me for the connection information.

To learn how to use Java with IRIS, I attempted to deploy two apps from Open Exchange:

https://openexchange.intersystems.com/package/CRUD-GLOBALS-IRISNATIVEAPI...

When using "IDENTITY" as my primary key, I can select the last inserted ID with

SELECT LAST_IDENTITY() FROM %TSQL_sys.snf;

Actually this is how Hibernate + Iris' Driver acquires the inserted ID when mapping with

@GeneratedValue(strategy = GenerationType.IDENTITY)

Now, considering that I am using the type "SERIAL" as my primary key instead, how can I get the last inserted ID?

Note that with "SERIAL" I can forcefully insert any value for this ID, from which Iris will continue generating values...

I cannot get any further hint from the error message in red in this screenshot. Is there any clue or details about the connection failure that I could look for?

Hi Community,

Watch this video to see how to connect to InterSystems Cloud Services from your Java application using the InterSystems JDBC driver:

I'm using a JDBC driver to connect PGSQL -> Cache. I'm noticing when I run SELECT queries and COUNT(*) command against the same table, I get different result sets. I'm pretty new to Cache in general - so I'm trying to understand why these would be different.

Examples (TransID and InvNum should occur in every "row"):

SELECT COUNT(*) FROM ACCT.Services = 1,090,324 WHERE ACCT.Dept = 483

SELECT TransID FROM ACCT.Services = 1,085,776 WHERE ACCT.Dept = 483

SELECT InvNum FROM ACCT.Services = 586,023 WHERE ACCT.Dept = 483

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')"
