Open Database Connectivity (ODBC) is a standard application programming interface (API) for accessing database management systems.

Learn more.

Hi everybody,
I am trying to connect with an IRIS database where to retrieve data and import them to SQL server but the access gets denied.
I would appreciate your help,
Thank you,
Jeb

I have following information:

Data Source Name --> I use it as the server name

Host(IP Address)

Port

Namespace --> I could use it in my script

import pyodbc

How to avoid ODBC query timeouts

InterSystems FAQ rubric

To disable the timeout, set the query timeout to disabled in the DSN settings:

Windows Control Panel > Administrative Tools > Data Sources (ODBC) > System DSN configuration

If you check Disable query timeout, the timeout will be disabled.

If you want to change it on the application side, you can set it at the ODBC API level.

Set the SQL_ATTR_QUERY_TIMEOUT attribute when calling the ODBC SQLSetStmtAttr function before connecting to the data source.

I created %ZSTART, having just learned about it. I included some minimal code to test it, as follows:
%ZSTART
SYSTEM
WRITE "SYSTEM.",!
QUIT
JOB
WRITE "JOB.",!
QUIT
LOGIN
WRITE "LOGIN.",!
QUIT
CALLIN
WRITE "CALLIN.",!
QUIT

Now Terminal still works as normal, and sure enough I get "LOGIN" displayed, but when I start Studio I get an error message such as the following. I wonder what Caché ODBC has to do with it.

ODBC / JDBC data truncation

Hi, I hope this post helps.

The bottom line: MAXLEN is relevant mostly for odbc/jdbc connections and you need to specify an appropriate value within your tables (classes), otherwise the data might be truncated when you query it, or even fail when you try to insert data.

Long story:

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')"

Hey everyone,

I'm currently running into a very weird issue to where I am trying to connect with a 64 bit version of SQL Server Management Studio (SSMS) to a HealthShare instance. I have created a System DSN using the Drivers (image below) that were downloaded with the Client version of the install and I'm able to successfully connect using my credentials.

Attempting to setup an outbound (I'm querying out, not querying the IRIS db) SQL connection. I am connecting to a PostgreSQL database, name "hl7interface".

I have setup the odbc.ini file at /usr/local/etc with the following contents:

[HL7Interface2]
Driver = PostgreSQL
Description = HL7 Interface DB
Servername = localhost
Port = 5432
Protocol = 7.4-1
#userName = postgres
#Password = <real pw here>
Database = hl7interface
ReadOnly = no
ServerType = Postgres

I have set the /etc/odbcinst.ini file with the location of the PostgreSQL driver:

Is it possible to authenticate an xDBC (ODBC/JDBC) connection to InterSystems IRIS via (a 3rd party) OAuth server?

For REST APIs this is possible, but could this be achieved with OAuth?

Out-of-the-box the ODBC/JDBC Drivers don't seem to have this option, but maybe some custom code could enable this? perhaps via Delegated Authentication and some OAuth classes customization, or some other way?

Has anyone done this already and can share how it was implemented, or someone with some guideline suggestions?

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.

Replicating Audit Log Near Real Time
Many organisations implement centralised log management systems to separate and centralise the log data in order to e.g. automate threat detection (and response) and to comply with regulatory requirements. The primary systems of interest are the various user facing applications, but increasingly also other kinds of systems including integration platforms.

If multiple InterSystems products are installed on the same system, the latest version of the InterSystems ODBC driver among the installed products will remain registered in the driver manager.

You can change to any driver by changing the registry entry below.

Please note that running RegFiles.bat does not change the ODBC driver.

The registry entry is as follows.

I am very new to IRIS. We are developing a PHP application that connects to an IRIS instance of one of our vendors. I am having trouble with a specific table. When I need to query this specific table for specific fields, I am receiving an error. However, if I change the call to get all columns (`*`), there is no error. I get 37K records returned.

Hi,

We're using a database gateway from IRIS to Oracle using ODBC. It has been occurring a character set issue that invalidate special characters.

Oracle support has found data type missmatch in ODBC debug while transfering data between the databases.

ODBC was download from official website.

Is there any Intersystems contact to send it to check whether there is a ODBC issue? I hasn't found any directy contact in Intersystems in website.

We are updating a C# module which creates consumes an OdbcConnection from System.Data.Odbc. This module used to create a DSN-less connection through the InterSystems Cache driver, and we are updating it to call the IRIS ODBC35 driver following migration of the target database.

The Cache connection was formed formatted as follows:

Hi,

I am trying to load all the data tables from one iris server to a client server but some of the tables data failing to load all the time. But I can load around 100 tables successfully but 8 to 10 tables are failing all the time. I made an IRIS odbc connection using odbc driver to load the data from tables.

Also I can see read server loop error message on the iris server side as the same time the table loading fails.

Please find the screen shot attached which shows the error on client server.

Hi all,

We are doing a SQL server upgrade to SQL server v.15 from a legacy server which had v.10 . I have our Cache server as a linked server int order to pull data from our system. When building out the ROWSPEC, I have my fields typed as %String with various lengths with one field having a max length of 15000. The SQL server is trying to interpret this as a text data type instead of varchar(n). Text is a depracated data type since SQL server 2008. The error below is produced when trying to query from this view

Although, I can successfully connect and retrieve data in MS Excel using ODBC connection where I have configured my DSN and all
