Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database.

Currently could be downloaded from here.

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?

LS,

I'm executing a query using JDBC on a PostgreSQL db:

SET statement_timeout TO 600000000; COMMIT SELECT * FROM bi_hour

The query is aborted with the following message:

FOUT #5023: Fout in Java Gateway: JDBC Gateway getClob(0,2) errorBad value for type long : active

The column 'blocked_status' contains the value 'active' is of type 'text'. I figure somewhere the SQL Gateway tries to convert the text value into a long but I can't find where, any suggestions?

Java Connection Strategy

We are planning to build a REST API with the Java Quarkus Framework.

  • There'll be a connection pool;
  • The DataSource instance will be automatically injected from the connection pool;
  • We will use JDBI to do SQL instructions and this will give us automatic Connection and Statement management;

This Caché instance already have COS applications running and consuming connections and licenses.

After doing this, we will migrate to IRIS.

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.

Intro

In a fast-paced digital era, effective communication is crucial. This article introduces a Java-based chat project, combining the strength of IRIS database and ChatGPT intelligence. Built on Java, it goes beyond real-time messaging, leveraging IRIS and ChatGPT for an enhanced chat experience. Also, the name of the project references the cultural classic - Star Wars.

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.

I have a case where I need to look up the NPI provider against an External MS SQL database to retrieve our Provider Identifier to send to a downstream system. In the past I would use a Business Process (BPL) to connect to the outside MS SQL via JDBC and get that information for me. But I was thinking instead of creating a BPL process to do this, would it be better just to link to the outside MS SQL database table to retrieve the information in a SQL statement within a DTL?

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.

REST service with 11G Sql

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:

The ideal number of table permissions to assign for your users is zero. Permissions should be granted upon sign-in based on the application used for access. For web applications, we have a simple way of doing this by appointing application roles, matching roles, and required resources in the System Management Portal.

ODBC and JDBC connections present a different problem, however, especially when third-party applications are involved. As providers of an ERP system, our customers often wish to be able to employ various software packages to integrate with or report on their data. Many of these programs are capable of running any kind of query. Yet, letting them do that can be devastating to a customer’s data.

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 just wrote up a quick sample to help a colleague load data into IRIS from R using RJDBC, and figured it's worth sharing here for future reference.

Ultimately it was pretty simple, aside from IRIS not liking "." in column names; the workaround is to just rename the columns. Someone better at R than me could probably provide some generic approach. smiley

Tring to Performing following script in IRIS but do not know how to format Date. Normally, I would use TO_DATE or TO_TIMESTAMP in the actual queue statement below, but since I'm using Prepared Statements, I do not know how to format date in 'values' that is being used in the %Execute. It generates errors. I'm updating an Oracle Database via a SQL JDBC Gateway Connection. Does anyone know how to pass in Dates?

JDBC counts don't match

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

I was attempting to test a Linked JDBC View to MS SQL database and noticed I could not connect. When I look at the JDBC Gateway I noticed that at the Server Level it was down. However the page keeps timing out when ever I attempt to make any changes or start it, it will not respond.

I thought I had found the Cache command to start it but it will not start. Is the following steps correct?

using Procedure Parameters with ODBC/JDBC

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')"

Hello,

I have a question regarding the Intersystems Caché Database and its jdbc driver. I need to set the connection timeout for the database, but I couldn't find any documentation stating that the jdbc driver for Caché supports setting the connection timeout. However, I noticed that the jdbc driver for the Intersystems Iris Database appears to support this feature.

My question is, can I use the Iris jdbc driver to set the connection timeout for the Caché Database?

The jdbc driver I use: cache-jdbc-2.0.0.jar
