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:

ClassMethod RunVersionChange() As %Status
{
    Set sample = ##class(dado.TblSample).%OpenId("42")
    Write !,"VERSIONPROPERTY value: "_ sample.VersionCheck
    
    Do sample.StatusSetObjectId("AL")
    DO s

Hi Developers!

With InterSystems IRIS Cloud SQL recently becoming Generally Available, some of you may have had a chance to try it out. Or maybe you used it for your contest entry or during the EAP period. We're curious to learn what YOU think of it. So, have you already tried the new service InterSystems IRIS Cloud SQL? 

We have launched a new Ideas Portal category dedicated to this database-as-a-service (DBaaS) where we're looking for your ideas on how we can improve InterSystems IRIS Cloud SQL. 

Or share your experience with the service in the comments to this post. 

Hello,

I have my server setup a resource server.  When a user calls our API they submit a bearer token as authorization and in our dispatch class AccessCheck() we validate the JWT using ##class(%SYS.OAuth2.Validation).ValidateJWT(). 

If I include a scope to check in that method I get the error Scope check may only be done on requesting client and I'm not sure what this means. The method works without include the scope and will let me know if I have an unsigned token or an expired token.  

I noticed that the implementation of the method calls Set token=##class(OAuth2.AccessToken).Open(access

Hi community,

I'm calling to a API that it is retrieving the content of a file as Content of response. I'm catching the binary but I need to convert this Stream to a Base64 string.

I'm trying to convert a %Stream.GlobaBinary to a Base64 string using the following code, but it doesn't work.

do stream1.Rewind()
set response = ""while 'stream1.AtEnd {
    set temp=stream.Read(4000)
    set temp=$system.Encryption.Base64Encode(temp)
    set response = response_temp
}

The content is not correctly converted to Base64

Also, I've tried to convert it as dynamic JSon and get the stream as

I'm currently making some changes to legacy code and I've noticed that it uses "i $i("  all over the place. Testing in terminal seems like this does the same thing as "do $i()". Is there a difference between these two (and if not is there some interesting history around this)?

Hi, 

I'm trying to send alerts in Ens.Alert process to a teams channel. 

I have already created a production that transforms the incoming alerts and send to a set of user's email but I also wanted to sent it to the teams channel

Any thoughts around this?

I have two timestamp values and also I have interval time, I need to split the timestamp based on the interval time. Like 
Start Time is '2024-01-01T10:00:00'
End Time is '2024-01-01T11:00:00'
Interval Time is 15 minutes
I expected the result is:
'2024-01-01T10:15:00'
'2024-01-01T10:30:00'
'2024-01-01T10:45:00'
'2024-01-01T11:00:00'

Hi Guys,

Any Idea on how can make a dynaTree with 4 levels hierarchy (attached), I'm using the below code but sometimes works and other cases it doesn't?  

Set locId=..locId,pos=1,(pLineArr,astArr,compArr)=""
&Sql(Select Parent->Name,ID into :Fac,:kLoc from MSDS_COM.Loc where Parent=:locId)
Set:SQLCODE (Fac,kLoc)=""Set pTree(0,"ch",1) = ""Set pTree(1) = $LB(Fac,locId,1,"","")
Set Sql="Select ProductLine from MSDS_Serenity.ProdLineDetails where Active=1 and Loc="_kLoc_" group by ProductLine order by ID"Set RS = ##class(%ResultSet).%New()
Do RS.Prepare(Sql)
Do RS.Execute()
While 

We are writing a custom Business Operation to interact with a downstream SOAP web-service. Classes for the SOAP operation were originally generated using the SOAP Wizard, then modified. This is functioning OK, but we'd now like to set the ReplyCodeActions setting on the operation and are struggling to make it visible via the management portal. How can we achieve this?

The classes are structured like this:

• The Operation uses class TNHS.SOAPclassExtra
• TNHS.SOAPclassExtra  Extends TNHS.SOAPclass
• TNHS.SOAPclass  Extends Ens.BusinessOperation
• Ens.BusinessOperation has a property ReplyCodeAct

Hi everyone.

Is there a sensible approach to having a lookup table in Namespace A, and then accessing this from Namespaces B, C, D (etc)?

I'm trying to avoid creating a Global mapping of the lookup table global (^Ens.LookupTable) as I fear that it would then link all other lookups in that global and lead to some unexpected behaviour, but would be open to trying something in this realm if it's the best option.

Another approach I have considered is creating a custom lookup function that is run from the secondary namespaces that does some namespace hopping, but it feels messy. Something like:

The following code call the method of the same name as defined in the nearest superclass:

Class MyClass Extends%Persistent
{
  ClassMethod Foo()
  {
  }
}

Class SubClass Extends MyClass
{
  ClassMethod Foo()
  {
      do##super() // <----
  }
}

Not let's say I want to call Foo() super class method but from another method :

Class SubClass Extends MyClass
{
  ClassMethod AnotherMethod()
  {
      do##super().Foo() //will not work
  }
}

This is possible in some other programming languages such as C# or Java.

I cannot find anything in documentation

InterSystems has encountered a defect that causes some upgrades of HealthShare® Health Connect to fail. This only affects instances that are not licensed for the use of FHIR® and that have interoperability-enabled namespaces. Under these conditions, the upgrade fails with an <HSFHIRErr> error.

This defect only impacts upgrades to version 2024.1 of HealthShare Health Connect.

The affected version, 2024.1.0.263.0, has been removed from distribution.  A new Point Release is available:

EnsLib.File.PassthroughOperation has File Name property with default value: %f_%Q%!+(_a)

The Management Portal documentation description of the property:

Name of file to output the document(s) to. May include timestamp specifiers. The %f specifier if present will be replaced with the name of the document's original source filename (stripped of characters illegal in target filenames).

See the method Ens.Util.File.CreateTimestamp() for documentation of timestamping options.

More documentation describing the behaviour of %f: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Pa

We have JSON type data in a Dynamic Object.  Is there a simple way to export / dump that data to a delimited string or file?

e.g.

"ClassB":{"ClassName":"ClassB","ACount":5352149227,"BCount":5352149227,"CurrentDiff":0,"PreviousDiff":0,"ReportDate":"2024-03-02 00:00:00"}}

Hi Community,

I am trying to read a JSON file and convert into HL7 message.Please find the example below

Set Jsonobj={"Doctype":"ADT^A01","PatientId":"123","PatientName":"Alex"}

Set Dynjsonobj=##class(%Library.DynamicObject).%FromJSON(Jsonobj)

Error :<THROW>%FromJSON+37^%Library.DynamicAbstractObject.1 *%Exception.General READ error while reading input stream 10 Line 1 Offset 0

I am getting this error while reading the file,Can you please tell me where i am doing wrong in converting the file?

I would like to compare two Registered Object and list the properties that differ.
For now, I achieve this :
 

ClassMethod AssertObjectEquals(object As%RegisteredObject, objectToCompare As%RegisteredObject, Output msg As%String) As%Status
{
        Set returnValue = 1// check if same classSet className = $CLASSNAME(object)
        If (className '= $CLASSNAME(objectToCompare)) {
                Set returnValue = 0Set difference = "not same class"
        }

        If (returnValue) {
                // Get the definition to browse properties

Hi Community,

It's time for the new batch of #KeyQuestions from the previous month.

Here are the Key Questions of March chosen by InterSystems Experts within all Communities:

I though this is a pretty cool way of installing webterminal in an environment where I had Management Portal / Visual code access, but I had no terminal access. zpm was already present. otherwise you could add it in the same class.

1. Create the following class file
2. Compile. This will take a while, and then you will see the output from zpm!
3. You can now open the webterminal by opening http://your-host/terminal/

Class Theo.Util.Webterminal Extends %RegisteredObject
{

/// Description
ClassMethod install() As %Status [ CodeMode = objectgenerator ]
{
    zpm "install webterminal"
}

}

It is probably somewhere in the doc. So hard to search. Hope InterSystems going to AI on their community/support data. 

How to see a meaningful value in management portal - sql explorer. For instance
Class MySetting Extends %Persistent{
     Property Name As %String;

Class MyObj Extends %Persistent{
    Property Setting As MySetting;

When browsing MyObj in management portal (just select * from MyObj - lazy to do a join), I will see 1,2.. values in the Setting column. I would like to see the Name. I do not want index MySetting with Name as primary as the name can change

Thank for your comment.
