#JDBC

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 There,

I am having issues trying to obtain a JDBC driver which is backwards compatible with java 6 for a solution which will call my IRIS instance, I have already logged a WRC ticket which is looking unlikely that there will be any development to create a driver for such legacy tech.

The Java 6 app is end of life, however won't be replaced until after my project goes live, hence why I ask the question.

Recently I started moving some of our JDBC Gateway configurations over to using the Microsoft JDBC Gateway driver instead of using the jTDS open source driver. I have noticed since then that those Objects that are using Microsoft JDBC Driver are throwing a lot more errors than the jTDS driver ever did, which I can understand however I am puzzled that I keep running into an issue with the Java Gateway Service within the Interoperability engine.

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!

Ran into an issue with our upgrade from HealthShare Health Connect 2018.1.3 to IRIS HealthShare Health Connect 2022.1, that I thought I would reach out about, I already have a ticket open with WRC and started a chat on Discord. We have a couple of MS SQL tables that I have setup as Linked Tables within Cache to query NPI, Patient Account Information, Visit information, etc... When we upgraded last week we found that within a day or even a half a day that we were having problems with our JDBC connections.

Hi Community,

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

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

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?

Thanks

JDBC Gateway Server Crash

I am trying to troubleshoot an issue I am having with the JDBC Gateway Server crashing at the %SYS level. I have numerous Linked Tables that are using JDBC to connect to a MS SQL database/tables to query values. I have written queries in other class files and within the class definition of the linked table to do the queries.

1. Should I be running the query in the class definition of the linked table as a class method? or is it best practice to run the query as a class method outside of the class definition of the linked table?

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?

Hi ,

When I use jdbc driver to query the column info ,the "REMARKS" field always show the same as the "COLUMN_NAME" field.

When I use the sql "select * from INFORMATION_SCHEMA.columns a where a.table_name='some table name ' " to query columns info,there has a "DESCRIPTION" field ,the value is some comment for the current field.

So is there anyway to return the description to the jdbc remarks field? And is there anyway to update the desciption or remarks field? Or is there some other way that I don't know to manage column comment info?

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?

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.

Consider a Natural Key with an Identity (Serial) field.

I cannot seem to acquire the generated value after persisting my entity. That is, the returned entity by Spring Data's "save" does not have the generated value.

The value is generated by the database, and I can query it after repository.save(entity).

I have done some testing and created a Github repo with it...

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)

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.

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

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 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?

Hi Cache team, I am in the need of listing all the user defined schemas that are present my Cache db and also the user defined tables and views and Columns of those tables and views through Queries. So that I can write some JDBC code to run the queries and fetch the above metadata. Any help is appreciated.

Thanks in Advance,

Kranthi kiran.
