Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database.
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 stringinstead of NULL.
HI I am using below code to retrieve the last inserted ID of the table. It works when we do not set any custom column as IDKey. If we define any column as
IDKey below code does not return any IDKey. I know when i am defining any column as IDKey its not auto generated , but whats the best way to get the ID column value
This is another 5-minute simple note on invoking the IRIS JDBC driver via Python 3 within i.e. a Jupyter Notebook, to read from and write data into an IRIS database instance via SQL syntax, for demo purpose.
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
Hi! I am creating a Jasper Report using IRIS like DB, I've created my Data Adapter to connect with my DB configuring the JDBC connector and it works perfectly:
But when I try to create a report connecting to my DB I am getting this error:
Hi! I am working in a java project (Spring Boot+ Maven + Hibernate) using jpa/hibernate to manage the persistance with the IRIS database from the Docker image (store/intersystems/iris:2019.2.0.107.0-community) and I've found an issue using the IRIS instance, when I define tables with relationships OneToMany, ManyToOne or ManyToMany and I try to fetch all the rows of the tables using the default method findAll (JpaRepository implements that method to get all the rows by default) the query automatically exceeds the limit of licenses availables.
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?
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.
IRIS and Ensemble are designed to act as an ESB/EAI. This mean they are build to process lots of small messages.
But some times, in real life we have to use them as ETL. The down side is not that they can't do so, but it can take a long time to process millions of row at once.
To improve performance, I have created a new SQLOutboundAdaptor who only works with JDBC.
BatchSqlOutboundAdapter
Extend EnsLib.SQL.OutboundAdapter to add batch batch and fetch support on JDBC connection.
From time to time we develop an Ensemble Production with simple SQL Inbound data from external databases, we need to develop a few new classes. There are at least:
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.
However, few people know what technology the agency chose for storing and processing the data collected by Gaia. Two years before the launch, in 2011, the developers were considering a number of candidates (see “Astrostatistics and Data Mining” by Luis Manuel Sarro, Laurent Eyer, William O’Mullane, Joris De Ridder, pp. 111-112):
We are trying to script a High Availability Shutdown/Start script in case we need to fail over to one of our other servers we can be back up within mins. Is there a way to configure the startup procedure to Automatically Stop/Start the JDBC server when shutting down or starting up cache? is there an auto setting we can change?
We are using BI tool for reporting which required to connect TrakCare system using JDBC Connection Can some can assist with Jar file which is required for the connection or anyone did befoe?
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.
I'm new to Iris, trying to follow this guide ( https://community.intersystems.com/post/k-means-clustering-iris-dataset ) about using clustering. I've followed all instructions until showing the data. At that point, `dataFrame.show()` fails with `java.sql.SQLException: Access Denied`.
We have a new requirement being push down by our Data Security to no longer use Local SQL Accounts to access our Databases. So they asked me to create a Service Account that is on the Domain for our connections to each database.
I tried just changing my JDBC connection to using this Service Account and Password but I am not having any luck trying to connect to the database.
" Connection failed. Login failed for user 'osumc\CPD.Intr.Service'. ClientConnectionId:ade97239-c1c8-4ed1-8230-d274edb2e731 "
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?
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?
Has anyone use any other setting then -1 on the Stay Connected setting on a SQL.OutboundAdapter? I am having issues with a particular database and wonder if it would be beneficial since I only connect once a day to read the data from the Adapter to create an HL7 message.
I have some problem with getting data from external source (PostgreSQL) via JDBC and load it in DeepSee and I resolved some problems while writing this question :)
