#ObjectScript

20

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.

Documentation.

First,

Forgive me if this is a rather low-level question - I am a physician informaticist who is learning cache/mumps for the first time. I am sure this probably relates to some setting but I can't find a similar issue anywhere.

When I create a list, and then try and return that list - I get a bunch of symbols back along with my results, or sometimes I just get symbols.

I pasted a screenshot below. Thank is advance for the help!

Initialise object list

How do you initialise a list of objects of a particular type?

I have tried the following code and I get an undefined when I try to insert.

I can do this and it works but I don't know if it is correct.

Is there any way to do something like this?

Set a= New list of Accciones()

Thank you.

Working with Named Pipes

While creating my latest examples for the JavaContest I faced the need
to communicate with my code from a program in IRIS to my Java code.

Communication with |CPIPE| worked as READ or WRITE but not both?
In the Documentation Named PIPEs are explained rather shortly.
"Once open, a pipe acts like an ordinary device." Not so precise.
I failed to achieve my expected READ/WRITE as TCP would offer.

Connect to hardware

Hello,

If this question is in the wrong section, I apologise.

Has anyone ever used Cache Object Script to connect to any hardware such as a sensor?

What I mean is this :-

Lets assume that code has been written in Cache Object Script where it can detect breaks in electrical connections.

Hey all,

I have been creating a class to handle file encryption by using GPG keys. I pushed my code out today and my encrypt and decrypt methods weren't working. About a half an hour later in troubleshooting I found out that it needed to be a syntax change. My method has three parameters to it. Examples below:

This is how I was calling it in the test system with no issues:

do gpg.Encrypt()

This is how I was having to call it in my production system to work with no issues:

do gpg.Encrypt("","","")

We are running Batch job in scheduled task and the messages are picking in single session and it is not easy to trace the record.

I used the Set ..%SessionId= "" at before sending the message to BP but I see the session Id is '1' created for each message.

Is there anyother way to create new session for each message sending to BP?

Thanks,

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,

When for any particular reason I need to update a record and don't want to pull the triggers, the keyword %NOTRIGGER can be used. But I've been trying to do the same when I change the row using the object approach, but I can't find it. Anyone knows if it's possible to avoid pulling triggers when working with objects?

Sadly, the utility "DISABLE^%NOTRIGGER" doesn't seem to exist ;-)

Thank you,
David

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

SQL Query returns x00

Hey Intersystems Community-Member,

Following Issue: When I update a SQL table like (update OnlineV3Admin.ParameterApp set popuptext = '' where ID = '1') and then read it for my Json WebService there is a /"x00" in my Json.

What is the best option to disable that? I need here a empty String and not /x00.

Any ideas?

Best regards,

Florian Hansmann

I am reaching out to find out if anyone has come across a similar dilemma.

In my current role, I have been asked around the best way to design some patient labels for a client.

I primarily would stick to what I know and veered towards designing the label in ZPL and then creating a Abstract Class to call the ZPL code, however I have been asked why not to design via JReport. The patient labels will be processed via thermal ink printers primarily Zebras, I am wondering if anyone out there has come across this or would recommend to stick to what you know.

I'm trying to tie IRIS (2019.1) into our Concord Fax cloud-based email-to-fax workflow. We have some sites that require a fax be sent to multiple locations based upon certain data (ie Radiology and Emergency departments). Unfortunately, CC-ing does not work with Concord Fax so I need a way to send the email, change the recipient, and then send it again if certain criteria are met. Is this possible? Do I need to duplicate and rename the method, calling the second one in the MessageMap?

Here's what my code currently looks like:

Hi All,

I have been given the following xml class file with objectscript code that has methods that I need for file conversions. These method implementations will do necessary conversions but I don't know how to add it to Iris studio and run it as a task or maybe if it must be put on any location and call each method from the terminal and even if so how do I then call it.

Please advise how to go about this.

I'm trying to write an ObjectScript function that sorts version numbers to help learn ObjectScript. This is all I can think of after staring at VS Code for a while, but I don't know where to go with it. Can someone please help out with a tip? The goal is to take something like ["1.4.5", "0.5.3", "6.3.2", "1.2.4"] and turn it into ["0.5.3", "1.2.4", "1.4.5", "6.3.2"]
