Hello!

I would like to find all classes not up to date in a namespace programmatically.

With IRIS Studio, we can see the single "+", but I don't know how to do that with a script.

Set sql = "SELECT ID, Name FROM %Dictionary.ClassDefinition WHERE NOT ID %STARTSWITH ?"
Set params($Increment(params)) = "%"
Set tResult = ##class(%SQL.Statement).%ExecDirect(, sql, params...)

If (tResult.%SQLCODE'=0)&&(tResult.%SQLCODE'=100) Set sc = $$$ERROR($$$SQLError, tResult.%SQLCODE, tResult.%Message) Quit sc

While tResult.%Next() {
    // if class not up to date ??
}

DICOM document path querying

Say you have a DICOM document with an input information sequence with many sequence items. You could access every item one by one by looping and querying the path by passing it to the GetValueAt method as demonsrated below.

This works but there are some performance issues on my system if the document has to be read for each query (as far as I know, that is the case on my system). Is there a way of querying a path, which would return the sequence items as an array? I think I am missing something. With 900 items the process takes around 20 seconds currently.

Hi Everyone,

I am trying to reference a field, however, in our production environment, it can be found in the first second or third iteration. My code was only qualifying on the first iteration. I have been attempting to include all iterations, but I have come up short...below is a snippet of what I am attempting to use. My original code simply had GetValueAt("PID:13.4") but this only referenced the first iteration. Thanks for any thoughts!

We have a data transformation where source is object collection (populated from a json file) and target is EnsLib.EDI.XML.Document.

If source file is large enough, transformation fails and we get <store> error and I quickly found this:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=EBPLR_DTL_foreach which at the bottom in "Avoiding <STORE> Errors with Large Messages" section tells to:

We have a custom business service that is triggered by a scheduled task. The service queries a table, iterates over the result set and sends a message on to a business process for each result. Happy path functionality is all fine.

However, when there is an error detected in the business service code, neither throwing an exception nor returning an error %Status behaves as we'd expect.

This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!

Is there a way to iterate ClassMethod's params, and get param's names and values?

The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):

I must be missing something. We have done encoded PDF's in the past with the Encoded PDF in OBX.5.5. When I have used this code in the past I was only working with 1 OBX, but I have a case where I am having multiple OBX's and having to loop through them and I am renumbering the outbound OBX.

When requesting /MDX2JSON/PivotVariables/Patients?Namespace Patients shoud be passed to a method but its not. When argument passed directly into the method it works.

<Route Url="/PivotVariables/:Cube" Method="GET" Call="WritePivotVariablesForCube"/>

Has something changed in IRIS and this syntax is deprecated, or is there a bug and the colon is ignored? What could it be?

This question is continuation from https://community.intersystems.com/node/534811

Has anyone had success with passing in a collections property within a SOAP request to a Soap Service in Ensemble? Please reply with how you set up that collections property. I am able to successfully send a SOAP request correctly containing the elements of the collection property to Cache, as seen in a custom soap log file which I am using to troubleshoot. But the collection property in the Ensemble request is not getting serialized, meaning MyContainers has nothing.

My.Request consists of a property, MyContainers, which can have 0 or more Containers (My.Container)

Is there documentation that shows the mapping between the management portal components and object script package.class.methods?
I am searching on-line documentation but have not been successful.
For example, in the management portal SystemOperation > TaskManager > TaskSchedule can map to the method: class(Monitors.Tasks).ListSuspendedTasks().


What would be a similar mapping for SystemOperation > TaskManager > TaskHistory?
I initially thought it would be something similar to class(Monitors.Tasks).ListTaskHistory().

Best Regards,

A new Health Connect customer has a few experienced Java folks on their interface team. As they get more into Health Connect and learn Caché ObjectScript they thought it would be useful to have a list of common Java statements with an equivalent statement in ObjectScript. They mentioned string manipulation as an example, but would be interested in other areas as well.

This seems like something that is probably already floating around somewhere. Does anyone have something like this or other "COS jumpstart for Java devs" materials?

Thanks,
Marc
