#ObjectScript

InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.

Hi all,

I might be losing my mind or do not understand how ObjectScript does string comparisons, but the following does not look right to me.

Is it really possible that you can't compare non-numerical strings other than with an equals or not equals?

USER>w ("45" < "46")
1
USER>w ("45" > "46")
0
USER>w ("V45" < "V46")
0
USER>w ("V45" > "V46")
0
USER>w ("V45" <= "V46")
1
USER>w ("V45" >= "V46")
1

In Python:

I have a situation where I have a handful of classes which I need to copy to another Namespace (which uses a different RoutineDB) on the same instance, load it and compile it.

Can anyone help me come up with a command that will do this quickly and easily? Perhaps something with extended reference?

This is somewhat time sensitive so thank you in advance for your ideas!

Example:

Method Execute (args...) As %Status {
...
 #dim statement as %SQL.Statement
 set statement = ##class(%SQL.Statement).%New(2)
 set statement.%Dialect = "CACHE"
 do statement.prepare(query)

 #dim rs as %SQL.StatementResult
 set rs = statement.execute(args...)

My questions are: 1) how do I get the size of args **2) how to get all values of **args **3) is it possible to modify the **args?

Has anyone come across a good using Embedded Python to convert a Python List object to an IRIS %List object?

My use case is I want to open an SQL entry with an Objectscript class method, then pass some information from that row into a separate Python class method which will then create a Python List object, then have the Python class method return that list back to the Objectscript class method in such a way that the Python List can be converted to an IRIS %List object for me to then use in the Objectscript code.

This applies to embedded and dynamic SQL queries in Caché ObjectScript. If I attempt to terminate the process via Management Portal, nothing happens. Neither does Ctrl C nor closing the terminal window in which my program is running, nor setting a stop flag in a global which is read by the program on each loop iteration. The only way to stop the query appears to be restarting the Caché server (which is running locally on my PC).

Hi everyone,

Does anyone know how to export projects via VSC?

I opened the project through the "InterSystems Tools" plugin (command is "Edit Code in Project") and I can correctly work on it.

However, when I try using the "ObjectScript" plugin to export the project (right click on the project -> "Export Project Contents")

This message appears and it is not possible to export the project:

0 3
0 2.7K

Hence the question: is there a way to do that?

The goal is to get data (from half a thousand to 3-4 thousands lines) from DB, calculate standart deviation then use it as logical condition in analyzer.

For example IF std > custom_value = show_the_result ELSE null

There is a STDDEV(MDX) method used in Analyzer but it is a measure and it can not be used as logical condition (correct me if i am wrong)

I'm exploring this right now: given a bunch of types defined as Pydantic models, how can I come up with an equivalent %RegisteredObject/%SerialObject and convert to/from (e.g., to support persistence and match validation as much as possible)?

People who know Python better than I do (e.g., your average undergraduate from this decade): is this a stupid idea or a cool idea? Has anyone else done this before?

Hi!

Here is the question in Russian Forum regarding roots extracting.

In Caché ObjectScript we use exponentiation operator (**) to raise an exponent to power. F.e. let's raise 3 to power of 3: 

USER> write 3**3 

27

And we use the same operator to extract the root. 

USER> write 27**(1/3) 

2.999999999999999963

And 2.999999999999999963 is not 3, obviously.

How to extract roots properly in Caché ObjectScript?

Hello community!

Is there any method/property/way in Caché to obtain something like unique identifier for installed Caché system? The idea is to get the identifier that will differ on any other installation/machine/etc, but will forever remain the same for the current installation, even if $zv changes (in case of update) or any data is removed from the database.

When try the following to send back SOAP Fault, is the following correct way?

Set fault=##class(%SOAP.Fault).%New()
Set fault.faultcode=$$$FAULTServer
Set fault.faultstring="Processing Error"
Set fault.detail= "Error on server"
Do ..ReturnFault(fault)

Count Number of Pages?

Hello,

We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS. One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.

In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?

Extract piece of string

Hello guys,

I was wondering whether there is another alternative to extracting a certain string out from a bigger one, rather than using the function $piece.

Maybe regular expressions? Another specific function?

Example:

Big string:

NAD+SLA+++TextIsHereNAD+SLA+++TextIsHere

String I want to extract:

TextIsHere

Function I'm already using:

I have a process that I am trying to duplicate from SQL Integration Services (SSIS) into Ensemble so that the rest of my team can help support any issues that may happen.

This particular job creates multiple dictionary files, but for each one of the dictionary files it creates, it also creates a control file that tells the vendor what to process.

Hello Experts,

I have a silly question of using InsertParam method and usage. I understand it is name value pair. I am using GET method to send a url and to get the details from server. URL has multiparameter

URL - api/Identifier/Image/?Verify.EDD={EDD}&Verify.Ethnicity={ETHNICITY}

I have used the URL in a method and called that method directly in the business operation. I am using Insertparam method -

Hi -

I'm wondering if anyone has coded up a means to create an extension for a %Persistent class from a base class to a sub-class without making a ton of assumptions about the Global structure. I'm trying to create a new "extension" record that would have the same ID as the Base Class

Class BaseRecord Extends %Persistent

and

Class SubRecord Extends BaseRecord

where I would have an instance of a "BaseRecord" and I want to turn it into a "SubRecord" instance and have all of the existing references to the BaseRecord survive.
