#JDBC

Everyone

There is a setQueryTimeout method in the% Net.Remote.Java.JDBCGateway class of IRIS, how to use Ensemble2016 to achieve this function?

Hi, We recover a large amount of data from an external database (SQLServer, about 1 million rows in JDBC).
However, we have treatment time issue.
This process takes more than 30 minutes whereas on a "classic" SQL Server Management Studio type request takes less than a minute.

While searching on the internet, I came across this article: http://makejavafaster.blogspot.com/2015/06/jdbc-fetch-size-performance.html
It explains how in Java, we can tweak the FetchSize parameter of the JDBC driver to optimize this kind of process.

Is there a way to access this JDBC parameter through the EnsLib.SQL.

I am using a Gradle Project for testing APIs, but I need to connect to the database.

I already put this on the dependencies:

And I'm trying to use this way:

But I'm keep getting this error: java.lang.ClassNotFoundException: com.intersys.jdbc.CacheDriver  

Is there any place that I can put a JAR file? Because the project has no lib folder (I already tried to add it, but it doesn't work).

Hi Guys,

I am trying to pull data from CacheDB and push into elasticsearch using logstash. In the configuration file i am giving the following. But it is throwing error No Suitable Driver Found for jdbc:Cache://ipaddress:port/namespace. Could anyone please help to resolve this ? I tried both JDK17 and JDK18 but no luck.

My Config file is as follows

input {
    jdbc {
    clean_run => true
    jdbc_driver_library => "C:\InterSystems\Cache\dev\java\lib\JDK17\cache-jdbc-2.0.0.jar"
    jdbc_driver_class => "com.intersys.jdbc.

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.

Building Application

Building our dynamic chat application involves a seamless integration of key components and technologies. Java serves as the heart that drives server-side logic and business operations.

SSH framework is a relatively representative framework of Java, which was popular many years ago. There are Struts+Spring+hibernate and Spring MVC+Spring+hibernate. Of course, I used the second one in college. If I can connect IRIS to Hibernate as a library, does it also mean that IRIS can be developed using SSH framework in theory?

Hi

I am fairly new to Ensemble development.

I was wondering what is the best process of returning the resultset from a SQL outbound adapter to the BPL that had invoked it.

Thank you for your help.

Kind Regards,

Salma

Hello all,

On one of my team's systems, we utilize a business operation with the EnsLib.SQL.OutboundAdapter to make SQL queries to another IRIS system using JDBC. To authenticate the connection, we utilize a user account on the target system.

We recently had a failure where this user account expired due to inactivity, causing all queries to error until the account was reactivated on the target system.

Due to MySQL's interpretation of SCHEMA differing from the common SQL understanding (as seen in IRIS/SQL Server/Oracle), our automated Linked Table Wizard may encounter errors when attempting to retrieve metadata information to build the Linked Table.

(This also applies to Linked Procedures and Views)

When attempting to create a Linked Table through the Wizard, you will encounter an error that looks something like this:

ERROR #5535: SQL Gateway catalog table error in 'SQLPrimaryKeys'. Error: ' SQLState: (HY000) NativeError: [0] Message: [MySQL][ODBC 8.3(a) Driver][mysqld-5.5.5-10.4.

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.

Class myRequestClass Extends Ens.Request
{

    Property MessageType As %String

}

The message that is passed to this class shows:

    <MessageType></MessageType>

Which writes the field as NULL with:

    tSQL = "insert into myTable (MessageType) values (?)"

    set tSC = ..Adapter.ExecuteUpdate(.tNumberOfRowsUpdated,tSQL,myRequestClass

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.

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. But maybe they are helpful for others.

1) The file path is on server side

I have done my first tests via JDBC.

Hi!

I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns. 

Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Here is my code:

Class Test.

I have been trying to track down an issue we are seeing in our TEST environment with Memory usage.

We have Several BP's for years now that take a HL7 message, parse it apart, and make calls to a Custom EnsLib.SQL.OutboundAdapter to have it execute Insert/Select/Update/Delete stored procedures against a MS SQL Database via JDBC connection. We are using Microsoft's JDBC 12.2 driver to do this.

What we are seeing is that IRIS.WorkQueue globals are being defined for these calls but then the IRIS.WorkQueue is not being cleaned up and taking up large amounts of Memory.

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!

I am currently working on a issue with WRC on one of my Inbound SQL Adapters not returning all the records it should be. If I looked at the count of the records in Ensemble and compare it to that of a Microsoft SQL View, Ensemble seems to be off by a few records here and there. I am using a full dynamic select statement in my settings of the adapter.

Any news about JDBC driver and Hibernate dialect on a public java repository, like mvnrepository? Today I need to download the jdbc driver and hibernate jar, add as an external resource on my maven config file to works.

We connect to MS SQL Databases using the Microsoft JDBC Driver 12.2 using the following URL

jdbc:sqlserver://<server>:<port>;database=<database name>;trustServerCertificate=true;integratedSecurity=true;authenticationScheme=NTLM;domain=osumc;authentication=NotSpecified

They want to migrate the databases to the Azure Cloud and in doing so we need the Authentication to change to go through Microsoft Entra.

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?

I want to INSERT a record in a database using JDBC in  OBJECTSCRIPT. At the same time, I want to obtain the insert ID. Is there a way to achieve this using the SQL Outbound adapter?

My code is something like this now:

Property Adapter As EnsLib.SQL.OutboundAdapter;

set sql = " INSERT INTO Prenotazioni_CUP "_
                  " (ID, cf
                  " VALUES (SEQTAB.NextVal, ?) "
set status = ..Adapter.ExecuteUpdate(.rs, sql, pRequest.cfAssistito)

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.

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.

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?

I am trying to replace one of our SQL Integration Service jobs with Ensemble and I am running into an issue executing a query against a MS SQL database using JDBC drivers.

My SQL Outbound code looks like this.

 Method SelectPaceartCharges(pRequest As osuwmc.Paceart.DataStructures.SelectPaceartBillingExtract, Output pResponse As EnsLib.SQL.

Where do I download the package cache-jdbc-2.0.0.jar. I'm trying to develop a java app that connects to a Cache Database to grab information? Thank you.

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

Property PetName As %Integer(DISPLAYLIST = ",Cat,Dog,Dove,Parrot", VALUELIST = ",1,2,3,4");

Java Code:

public String PetName;

public List<Pet> getPet() {
        return ser.findAll();
    }

List<Pet> arrayList = getPet();
        for (Patient list : arrayList) {

                 String pet= list.getPet();

                 System.out.

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?

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
