Apache Spark has rapidly become one of the most exciting technologies for big data analytics and machine learning. Spark is a general data processing engine created for use in clustered computing environments. Its heart is the Resilient Distributed Dataset (RDD) which represents a distributed, fault tolerant, collection of data that can be operated on in parallel across the nodes of a cluster. Spark is implemented using a combination of Java and Scala and so comes as a library that can run on any JVM.

The last days I've work with the great new feature: LOAD DATA With this post I would like to share my first experiences with you. The following points do not contain any order or other evaluation. These are only things that I noticed when using the LOAD DATA command. It should also be noted that these points are based on the IRIS Version 2021.2.0.617 which is a preview release. So it may be that my observations do not apply to newer IRIS versions.

WIN SQL is the normal editor used by most of the users .But we can't download large amount of data using winsql . So I have written a tutorial how to connect with a new Java based editor called Squirrel SQL which can easily download or export data in excel or any other formats. Also I included a Java JCBC connection program to connect with the IRIS database especially a mirroring/failover server.

I have a class that writes to an external SQL Server database. When the field is empty, it does not write the column and the column has the value NULL. In some cases, I want the column to be the value of the empty string instead of NULL.

As a former JAVA developer it has always been a challenge to decide which database was the most suitable for the project we were going to develop, one of the main criteria I used was their performance, as well as their HA configuration capabilities ( high availability). Well, now is the time to put IRIS to the test with respect to some of the most commonly used databases, so I've decided to create a small Java project based on SpringBoot that connects via JDBC with a MySQL database, another of PostgreSQL and finally with IRIS.

Good morning!

I am developing a Java project (Spring Boot + Maven + Hibernate) but I've a big issue when I try to define the Hibernate Dialect org.hibernate.dialect.InterSystemsIRISDialect... that dialect is neither in the Hibernate library nor in the IRISDriver class com.intersystems.jdbc

How should I define the IRISDialect in my project?

Thank you in advance!

Once a week we are attempting to load an XML file from Workday into a MS SQL table using JDBC and Store Procedures. There is approx 102999 records in this XML file. We are struggling with processing the entire file within a reason amount of time. We feed the XML through a BPL to then populate values in a stored procedure then call the stored procedure through a Business Operation. I have tried splitting out the Business Operations to make two calls, but we still continue to see an issue loading the XML into MS SQL.

Hi All,

I trying to get the DisplayList data of the ValueLIst from Java using Springboot. when I try to get the DislayList data via java code but I'm getting the VALUELIST data. I don't get any idea to get that DisplayList data. Below is the example

Hey Developers!

This week is a voting week for the InterSystems Full Stack Contest!

So, it's time to give your vote to the best solutions built with InterSystems IRIS.

How to vote? This is easy: you will have one vote, and your vote goes either in Experts Nomination or in Community Nomination.

We are creating a package (written in Caché Object Script) that will provide access to an external DB (MySQL). Because applications that use our package will be run from machines with various, potentially unexpected, operating systems, we’d like to establish a connection to the external DB without using DSNs (we’ve heard that setting up DSNs on certain non-Windows machines can be cumbersome and problematic).

Hi, I'm looking for a way to implement the JDBC pattern "executeBatch" in ObjectScript: https://www.tutorialspoint.com/jdbc/jdbc-batch-processing.htm

Since Ensemble 2017.2.2 there is a new method called executeParametersBatch : https://docs.intersystems.com/ens20172/csp/docbook/relnotes/index.html#D...

I'm referring to the document Using Cache with JDBC. Using this example, it sets the URL of the object ds of class CacheDataSource.

ds.setURL("jdbc:Cache://127.0.0.1:1972/SAMPLES");

My question is would you just copy and paste the URL from the login page to the string? I tried doing that and it returns an error saying "Invalid log file xyz"

Any help will be greatly appreciated! Thank you

In this article, we will establish an encrypted JDBC connection between Tableau Desktop and InterSystems IRIS database using a JDBC driver.
While documentation on configuring TLS with Java clients covers all possible topics on establishing an encrypted JDBC connection, configuring it with Tableau might be a little bit tricky, so I decided to write it down.

Without installing Kerberos has anyone Authenticated a SQL JDBC connection? Currently we are using local SQL Accounts to sign onto External SQL Databases, but we are being told that we need to switch to Service accounts that live on a Active Directory Domain.

I wrote with a little help a ZAUTHENICATE to do the Authentication for Ensemble, can I use something like that to connect to an External SQL Database using a Service Account on a Active Directory Domain?

Thanks

Scott
