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:

InterSystems IRIS provides a complete application development environment for building sophisticated data- and analytics-intensive applications that connect data and application silos. It is designed to work with all of the common development technologies in an open, standards-based fashion and supports both server-side and client-side programming.

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')"

InterSystems FAQ rubric

If the journal file is too large to be searched or filtered using the Management Portal, you can refer to it using the following two methods.

① How to use the ^JRNDUMP utility
② How to reference it in a program

During the realization of some required functionality, I discovered that I need to use Deflate compression, and found, that IRIS does not offer any options, $system.Util.Compress, works one way open (GZIP/COMPRESS) totally different, even for the same algorithms, I see that what I would expect as a result for Deflate somewhere there, but Compress returns something more. Is there any way to get a correct result using just ObjectScript without a need to use external tools? Was it really so difficult to have Deflate implemented in the first place?

Hello!

I wonder if anyone has a smart idea to extract an XML fragment inside a text document (incoming from a stream)?

The XML fragment is surrounded by plain text.

Example:

text...........
text...........
<?xml version="1.0" encoding="UTF-8 ?>
<Start>
...etc
</Start>
text...........
text...........

The XML is not represented by any class or object in the Namespace.

The XML can look different from time to time

If you have system tables implementing the "VERSIONPROPERTY" functionality, you may encounter error 5800. This article explains how this error occurs and provides solutions to resolve the issue.

When version checking is implemented, the property specified by VERSIONPROPERTY is automatically incremented each time an instance of the class is updated (either by objects or SQL).

For example:

Introducing mg_web

Hot on the heels of our announcement last week about our ultra-high-performance mg-dbx-napi JavaScript interface for IRIS, we are now pleased to announce a significant new technology - mg_web - which not only represents a new paradigm for JavaScript Web Frameworks, but also delivers significantly higher performance than even the fastest of the established Node.js Web Frameworks, whilst leveraging all the benefits of the big-three industry-standard Web Servers.

Hi,

We're getting a string sent to us by a client that was compressed using a java deflater (the zlib algorithm) and when trying to use $System.Util.Decompress() I get an "illegal value" error. I gather from other community posts that this is because the raw compressed string is missing the customized wrapper Iris automatically adds. I know this has been a longstanding issue for a while...just wanted to check if there'd been any updates to this functionality, or successful workarounds for decompressing raw zlib compressed data. Thanks in advance!

Hello everyone, I need some help.

I have to send some events for a government WebService that I already imported the WSDL and XSD's and It worked fine and I'm able to build the message and connect into the service, but It has been rejected with the message that the XML is wrong and the only diference between the Caché SOAP message to all the examples that the government gave us is the header:

This is how the Government is expecting the message:

Hi everyone,
I have this global with 2 informations in it: Reference (ex: 1329) and Code (ex: JMMK-G1D6).

^DataTest = 3
^DataTest(1) = $lb("","1329","JMMK-G1D6")
^DataTest(2) = $lb("","1516","AMEV-GVPF")
^DataTest(3) = $lb("","2333","4QC6-4HW3")

With ObjectScript, i want to test if Reference 1516 exists in the global.
In the InterSystems portal, i can do it with SQL (SELECT count(*) FROM DataTest where Reference = '1516'), but can we do the same in ObjectScript without SQL and manipulating the global directly ?

Question
· Apr 11
Delete the reference MEMORY

So as asked, I am not talking about KILL - KILL as stated in the docs:


This command removes the variable. If there are no further references to the object, this command also removes the object from memory,

I want to remove the object from memory even if it is still referenced in memory - I understand that cache is not a low-level programming language, But i was hoping there is a way.

Notice that have a RegisteredObject and it is a single reference, It is different than the UnSwizzles suggested in other posts.
