Hi devs!

Suppose I have an instance of a persistent class:

Set person = ##class(dc.Sample.Person).%OpenId(1)

Class is an ancestor of %JSON.Adapter.

How can I convert it to dynamic object with the properties that person.%JSONExport() provides?

{"Name":"Elon Mask","Title":"Associate Accountant","Company":"InterSystems","Phone":"799-933-5569","DOB":"1926-12-11"}

Couldn't find a right method. 

set dynObj = ##class(%ZEN.Auxiliary.altJSONProvider).%ObjectToAET(person) works, but adds id and classname, which I don't want to be added:

zw dynObj
dynObj={"_class":"dc.Sample.Person","_id":1,"N

The Good Old Days

The %Library.DynamicObject class has been in IRIS since before it became IRIS. If you have been using it since the Cache days, you may want to brush up on some of its changes.

In Cache 2018, the %Get method only had one argument. It was the key to retrieving from the JSON, meaning that if your JSON object called myObj, it would look like the following:

Hi,

If I map all globals with (*) to a database1, then would like to map specific only some globals eg. MYGLOB* to be located in a different database2, which mapping will override the other, so would all globals that starts with MYGLOB*  be placed in database1 or 2?

Thanks

In a project I'm working on we need to store some arbitrary XML in the database. This XML does not have any corresponding class in IRIS, we just need to store it as a string (it's relatively small and can fit in a string).
Since there are MANY (millions!) of records in the database I decided to reduce as much as possible the size without compressing. I know that some XML to be stored is indented, some not, it varies.
To reduce the size I decided to minify  the XML, but how do I minify an XML document in IRIS?
I searched across all the classes/utilities and I could not find a ready made code/metho

Artificial Intelligence (AI) is getting a lot of attention lately because it can change many areas of our lives. Better computer power and more data have helped AI do amazing things, like improving medical tests and making self-driving cars. AI can also help businesses make better decisions and work more efficiently, which is why it's becoming more popular and widely used. How can one integrate the OpenAI API calls into an existing IRIS Interoperability application?

I am currently monitoring our license use with a new rest-service I am implementing when I noticed my licenses on my instance being consumed and never released by Visual Studio Code.

For this I restarted my Instance, watched the licenses for a while, which remained at 1 during idle (I am guessing my MMGT Portal session uses 1) 
But when I connect to my Instance using Visual Studio Code (with my Instance setup in the extension already), suddenly 2 licenses are used. (I am guessing 1 for the "studio" and 1 for a terminal session, so far so good) 

But then when I

Hi Guys,

How can I use this same objectscript principle in embedded python to get the value of each field in my loop? 

  s sql="SELECT ID, Name, Age FROM Sample.Person WHERE Age="_Myage    

     Set RS=##class(%ResultSet).%New()

    Set Ret=RS.Prepare(sql)

    Set Ret=RS.Execute()

    While RS.Next()

    {

         Set name=RS.GetData(2)

}

it should be similar to this example which lists the whole row but how can I get the value of each field or if I can use GetData?  

Thanks

I ran into a situation where VS Code consumed all available web sessions and was unable to get to the Management Console to clear them. I was able to establish a terminal session, though.

Is there a method or routine available through the IRIS terminal that allows one to clear web sessions? I've searched the administration and class documentation and haven't found a solution.

I installed a local docker container instance from here:   intersystemsdc/iris-community

I'm trying to login:    http://localhost:52773/csp/sys/UtilHome.csp

I thought if I used SYSTEM as the initial username, I could login, but I get #822 Access Denied.

Is that the correct username? maybe there's a better location to pull the docker instance.

Migrating from Oracle, MSSQL, or other purely relational database systems to a multimodel InterSystems IRIS is a strategic decision that requires careful planning and execution. While this transition offers significant benefits, including enhanced performance, scalability, and support for modern architectures, it also comes with challenges. In this article I will highlight some of the considerations connected to coding to ensure a successful migration. I will leave everything connected to an actual migration of structures and data outside the scope of this article.

First, when you're considering migrating to a different database system, you need to understand your business logic, whether it's on the side of the application (application server) or the database server. Basically, where do you have your SQL statements that you will need to potentially rewrite? 

Hi devs!

What is the best way to return JSON in IRIS for a GET request in a REST app?

This is how I do it now:

ClassMethod GetAllPersons() As%Stream.Object
{
    d ..%SetContentType("application/json")
    Set rset = ##class(dc.Sample.Person).ExtentFunc()

    set stream=##class(%Stream.TmpCharacter).%New()
    d stream.Write("[")
    if rset.%Next() {
        Set person = ##class(dc.Sample.Person).%OpenId(rset.ID)
        Do person.%JSONExportToStream(.stream)
    }
    While rset.%Next() {
        d stream.Write(",")
        Set person = ##class(dc.Sample.Person).%OpenId(rse

I have an IRIS persistent class with a %Stream property whose value is a JSON object. I'd like to use a SQL trigger to pull some value out of the JSON and persist it in another property, for easy querying and indexing. See below for a minimal example:

Class PAB.DebugStream Extends%Persistent
{

Property Contents As%Stream.GlobalCharacter;Property msg As%String;ClassMethod InsertRow()
{
    set stream = ##class(%Stream.GlobalCharacter).%New()
    $$$ThrowOnError(stream.Write({"msg":"hello world!"}))
    &sql(insertinto PAB.DebugStream (Contents) values (:stream))
    $$$ThrowSQ

Hi Guys,

I am struggling with returning a SQL Query Result that may have multiple rows that can be searched.

set query = "SELECT Facility FROM FROM osuwmc_EnterpriseDirDB.RelationshipMedCtrID WHERE OSUmedcenterID = ?"SET rset = ##class(%SQL.Statement).%New()
 SET qStatus = rset.%Prepare(query)
 SET rset = rset.%Execute($Get(ID))
 do rset.%Display()

I need to take the values that are returned and say search them for a single value. How would I go about returning the EnsLib.SQL.Snapshot into a Array or List for it to be searchable.

Can this be done internally within the DTL, so I don't have to

Hi developers!

While developing web apps the security practice I consider safe and convenient is to create a special Role (e.g. equal application name) which contains security resources which application will need (SQL tables, priviledges, database access, etc) and assign it to the Web Application.
So the user gets this role once it loggs in to the application (via password, no password or delegated).

Convenient, right?

So, the question is, when I deploy the app as an IPM module what should I put as a database access?

For example I develop the app in the USER namespace so I list the access

When working with InterSystems IRIS, database developers and architects often face a critical decision: whether to use Dynamic SQL or Embedded SQL for querying and updating data. Both methods have their unique strengths and use cases, but understanding their performance implications is essential to making the right choice. Response time, a key metric in evaluating application performance, can vary significantly depending on the SQL approach used. Dynamic SQL offers flexibility, as queries can be constructed and executed at runtime, making it ideal for scenarios with unpredictable or highly variable query needs. Conversely, Embedded SQL emphasizes stability and efficiency by integrating SQL code directly into application logic, offering optimized response times for predefined query patterns.

In this article, I will explore the response times when using these two types of SQL and how they depend on different class structures and usage of parameters. So to do this, I'm going to use the following classes from the diagram:

Hi,

What is the best way to develop Angular applications while working with CCR?

CCR peer reviewers require submitting Angular source files, so that a peer reviewer has something readable to review. However, CCR environments require that you deploy compiled Angular applications to them.

I think I found my solution but I'm trying to understand better why it works. Forgive me as my descriptions here may be scattered but I'm trying to piece the puzzle together.

Scenario: I've found there are times when I make a request using a %Net.HttpRequest object and as I'm debugging and stepping through via the debugger in VSCode, if I try to access an object in the 'variables' menu, sometimes when I click that little expand button it will just spin and never load what's in the object to the viewer. This recently manifested itself in a process where we are calling a bunch of APIs and it go

Hi Guys,

I'm a newbie that doesn't know much about integratedML and looking for a first push into it, I've setup VSCode with my IRIS 2024.3 running in Linux and my understanding is that we can create models using SQL, so first, do I need to setup a specific environment where I can run my SQL commands to create & train Models or just using SMP, and do I need to install or enable Python ..etc things required to setup the environment?

Then if there are easy samples or training materials on how to create, train & deploy my model?  

Thanks
