Hi Community,

I am trying to save data into SQL table but each entry  getting saved twice in the SQL table. Is there any reason data is saving Twice in the SQL table 

I have created a %Persistent class for the fields

Please find the business operation below

Class Patient.DBOperation Extends Ens.BusinessOperation

{

Parameter ADAPTER = "EnsLib.SQL.OutboundAdapter";

Property Adapter As EnsLib.SQL.OutboundAdapter;

Parameter INVOCATION = "Queue";

Method OnMessage(pInput As Patient.PatientDBReq, pOutput As Ens.Response) As %Status
{
    Set Entry=##class(Patient.PatientDBReq).%New()
    Set Entry.

1.Background

        1.1 I met a few project that their interface servers were crashed. Cutoms wanted resume server as fast as we can. their servers are running at lan,and they can't use git,there are some namesapce in the server running different service,and usualy there is only one server.

        1.2 In the message,it has property in type of characterstream,as you know,the message search page doesn't support filtering with  property of characterstream,so it's so hard to find the messge you want.

        1.3 Other workmate may update the code on the server,and mybe their is something wrong.

Hi Friends,

In my business process I am updating cache table using dynamic query.

ex:

Set result=##class(%ResultSet).%New("%DynamicQuery:SQL")

Set sc=result.Prepare("SELECT %ID, Name, Salary FROM Sample.Employee WHERE Salary > ?")

If $$$ISERR(sc)

{

// here I want to capture the error details in trace , log , that I can see in production web page

}

could you please provide any suggestions to grab the error message.

I tried

Do DisplayError^%apiOBJ(sc)

Do $SYSTEM.OBJ.DisplayError(tSC)

end up with no class found , methods found errors.

I have spent 5 hours today for some clue.

Thanks ,

Prashanth

The task of handling office documents, namely docx documents, xlsx tables and pptx presentations is quite complicated. This article offers a way to parse, create and edit documents using only XSLT and ZIP.

Why? docx is the most popular document format, so the ability to generate and parse this format would always can be useful. The solution in a form of a ready-made library, can be problematic for several reasons:

• library may not exist
• you do not need another black box in your project
• library restrictions : platforms, features, etc.
• licensing
• processing speed

In this article, I would use only basic tools for work with the docx documents.

Hi everyone!

If you are working with IRIS 2021+ and you remove all of the built in entries for External Language Servers, there is an unexpected consequence that may prevent you from running an installer to upgrade your version of IRIS. This does appear to be a bug which has been raised with WRC, however there are some people that may have recently removed these settings and then will soon be upgrading their environment and could face this same issue.

Specifically, the removal of all the External Language Server entries will also remove the "[Gateways]" heading in the iris.

I'm using %XML.Reader  to open an XML file and use it's correlate method to try and convert it to a class.

The conversion fails with an error of:

ERROR #6277: Type attribute, LimitedFreeTextFieldInstance, does not specify valid type for XML input tag: Field (ending at line 3 character 118).

This is the XML

Hi Community,

The Second Batch of Digital Health Interoperability and FHIR Startup Incubator — Caelestinus, will start today!

Today 21 selected teams will start an eight-month journey at Caelestinus. During the incubation, teams introduce digital health interoperability into their connected medical service or medical device innovation and add the support of FHIR, HL7, DICOM, CDA, X12, and other digital health standards and its transformation using InterSystems IRIS for Health and FHIR Server with the help of experienced InterSystems team.

I know it is possible get the user using ##class(Security.Users).Get("username"), but I need to get a user by your email. How Can I get a user by email?

The title of the contest subject is not quite precise but addresses the %Library.classes involved.
What is meant is officially named Class Query and is dating back to the early days of Caché.
CLASS is used because it is embedded in a COS class.
Though there is a precise description in the official documentation it remains rather abstract.
My tutorial should guide you step-by-step through a simple example in COS to make it tangible to you

Hey all,

I'm trying to enable an existing namespace to be Ensemble enabled by doing the command do ##class(%EnsembleMgr).EnableNamespac($namespace,1), but I'm still getting the error message. Is there something that I'm missing? 

I've attempted to reboot the server and even went incognito to see if it was a caching issue, but I'm still not able to create an Ensemble production in that namespace.

When I do a write ##class(%EnsembleMgr).IsEnsembleInstalled() it returns a 1. The same goes for the command write ##class(%EnsembleMgr).IsEnsembleNamespace().

Hi guys, I defined a subclass to %CSP.Login and assigned csp/sys login page to this subclass:

But did not work, I get this error:

And more, the default %CSP.Login continues to be called to login when the user not logged yet
So, how can I do to replace the default %CSP.Login by my subclass?

Hi Community,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ Querying 6 Terabytes of Protected Health Information at Northwell @ Global Summit 2022

Hey all!

I was wondering if anyone had any input on how to troubleshoot classes in a terminal session? I'm currently writing an "adapter" so that way we can encrypt and decrypt files through GNUPG (PGP keys).

I currently have a %RegisteredObject class for this and am running into the excruciating pain of testing this. Every time I make a change on the RegisteredObject I have to renew the class and all of its properties in order to test the newly compiled code that I have written. I know that this doesn't seem like too much of a hassle, but after doing it multiple times it becomes tiring.

Hi Guys,

Is there a sample on how to send notifications via sms ? do we need an smtp sever or a external plugin in..etc?

Thanks

I am having an issue with a file not being deleted from the FTP server and returning an error to this effect.  The file, however, was fully processed.  This causes the file to process again.  

My question is I seem to recall a flag that can be set to enable more detailed tracing to be done on the FTP service/adapter.  However, I have not been able to locate this.  Does anyone recall such a logging setting or was I just dreaming?

Hi ,

     I'm using standard business service not(Customized business service). I'm not able to process the Hl7 data file which contains CRLF characters.It shows warning "Discarding  Received non HL7 data".

Also i tried UTF-8, Ascii,Unicode.. characterset . But it won't work. Please help me .

Get certified on InterSystems CCR!

Hello Community,

After beta testing the new CCR Technical Implementation Specialist exam, the Certification Team of InterSystems Learning Services has performed the necessary calibration and adjustments to release it to our community. It is now ready for purchase and scheduling in the InterSystems certification exam catalog. Potential candidates can review the exam topics and the practice questions to help orient them to exam question approaches and content.

While the classic solution followed rather close the concepts and design of the ancestors
Caché / IRIS allows a more modern approach to flexible/multidimensional properties

As you know in Caché / IRIS you have the possibility to define a property as Multidimensional as documented here:
https://docs.intersystems.com/iris20201/csp/docbook/DocBook.UI.Page.cls?KEY=GOBJ_proplit#GOBJ_proplit_multidim
and the explanation of how to use it
https://docs.intersystems.com/iris20201/csp/docbook/Doc.View.cls?KEY=GOBJ_proplit#GOBJ_proplit_multidim_values
Though the access is quite comfortable (in traditional COS sense) there are 2 main restrictions that hurt:
#1) It is not saved to disk unless your application includes code to save it specifically.
#2) It cannot be stored in or exposed through SQL tables
   there are some more
I'll show how to overcome these limits

Hi Guys,

I've the below code that copies 15000 records into a global, problem is that taking around 11 secs to finish and I'm wondering if there is any faster way (eg. would copying the file into stream and look through the stream makes it faster!?) because I've hundreds of files I need to process every time. 

Set File=##Class(%File).%New(FileAfUnZip)
Do File.Open("RS")
While 'File.AtEnd{
Set ReadData=File.ReadLine()
S ^DumpTempSeries(Equipment,Sensor,ID,MeasureDT,$I(i))=+$P(ReadData,",",5)_"^"_+$P(ReadData,",",6)_"^"_+$P(ReadData,",",7)
Quit:i=Total
}

Thanks

 Hi Community:

As you may know, I am the person who does the program and scheduling for our Global Summit sessions, so I can give you a sneak peek at our agenda before it is published.

I'm happy to report that we will have two special, four-hour workshops on Sunday, June 4, which is the day you arrive to register in Hollywood, Florida.

One is the return of the standing-room only 2022 workshop with our FHIR guru, Russ Leftwich - "Getting to Know FHIR: The Best Explanation of FHIR They've Ever Heard." Needless to say, we've reserved a bigger room.

Thanks to @Dmitry Maslennikov I have access to a Container for Caché.
It is based on Centos.
Is there anywhere a container based on Ubuntu available?

During my last migration to IRIS I met this Compatibility parameter

• NullSubscripts    true

0 - Throw error when referencing a null subscript.
1 - Null subscript references do not throw an error.

The consequences are shocking. This was allowed:

USER>zw ^rcc
^rcc=0
^rcc("")="***"
^rcc("",1)="*,1"
^rcc(1,"")="1,*"
^rcc(1,2)="1,2"
^rcc(1,2,"")="1,2,*"

But SMP had no idea what is going on. 

And after switching off that flag this was still partialy visible, but read-only

USER>zw ^rcc
^rcc=0
^rcc(1,"")="1,*"
^rcc(1,2)="1,2"
^rcc(1,2,"")="1,2,*"

I just don't understand.

One of the reasons why I love Cache and Iris is that not only you can do anything you can imagine, also you can do it in a lot of different ways!!.

Imagine that you have an integration running with IRIS connected by ODBC you probably only run SQL queries but you can also create stored procedures and inside write the code to do everything you can imagine.

I'm going to give you some examples but the limit is your imagination!!

You might wonder, wait! I don't know how to create a store procedure in IRIS.
