Is it a good practice to set the MAXLEN value of %Library.String property type? Will it lead to wasted storage if its not really using it?

For example, I have to store a 5 characters long string into the below str field. Which of the statement is recommended?

Property str As %String;

vs

Property str As %String(MAXLEN="5");

Hello!
I am trying access each "name" tag in the xml-file down below and want to display them through the trace in the production:

It would be interesting if there is some recommended documentation about best practices using Healthshare for interoperability.

Also, some how-tos or frequently asked questions about ObjectScript.

Or event better, if there are experienced developers who would like to share some common habits on their work with Studio / ObjectScript, which are valuable to do the developing work better.

For example, How to get the XML of a class and write it into a REST operation:

Hi all,

I am trying to use a %Status property on some of my Response classes. If the execution of a service goes wrong, I set the %Status property on Response with the value $$$ERROR($$$GeneralError, "pre-defined error message").

When I check the visual trace for this message and look for the %Status (property "status_code" on the image), it is displayed like this:

If I select to display the Body of the Response, I get the 'readable' form of %Status:

We are seeing something funky when using $ZSTRIP.

w $ZSTRIP("ZZZZTESTSLOCKTEST","<","ZZZZTEST")
LOCKTES
T

Shouldn't this be returning....SLOCKTEST and not LOCKTEST, the goal is to remove ZZZZTEST from the beginning of the string.

THanks

Let's say I have two lists of connected data where elements of listTwo only make sense if given an item of listOne as context:

listOne = ["A", "B", "C"]

listTwo = ["x", "y", "z"]

Tuples like ("A", "y") and ("C, "x") make sense, but "A" or "x" by themselves don't. I would like to pass in a list of such tuples into a method and have it handle each tuple in the list. So what would be the best way to format them given that ObjectScript does not have specialized tuples? Would it be nested $LISTBUILD lists or something else?

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:

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 ??
}
