Hi folks!

I'm curious if it is possible to change the class method to another class?

I call a method of a system class  to generate another class. But there is a bug/feature in a library class, so I need to tweak a bit the generated method, e.g. add additional parameter and change the line to "if" the parameter.

I hope to do this programmatically after class generation and change the code in a way I like.

What are the options?

SNN Encryption

I need to store an equivalent of the SNN (Social Security number). I need it to be encrypted and I'll have to be able to search for it once stored.

For what I've seen my options are: 

- SHAHash from the %system.encryption library. Simple and easy to implement. My question is, might collisions be a problem? We are talking about a 10 millions entry.

- AES encryption. In this case I'd like to know if there is a standard way for key management in the InterSystems environment.

Hi Dev Community,

I have a persistent Document class that has a FileName string property and another Question class that has an optional one-to-many relationship with Document.

I'm trying to add a SqlComputed property to the Question class (docFileName) where docFileName = Document.FileName if there is a related Document or an empty string if there isn't one. 

I'd prefer the property to be SqlComputed so that if Question.Document changes, Question.docFileName will automatically update.

Hi all, 

I'm trying to output a XML file, mapped from a ORU_R01 2.3 HL7 message, with a file name based of fields in the source HL7 message in the following format, 

source.{PIDgrpgrp(1).PIDgrp.PID:PatientIDInternalID(1).ID}_"-"_
source.{PIDgrpgrp(1).PIDgrp.PV1grp.PV1:VisitNumber.ID}_"-"_
source.{PIDgrpgrp(1).ORCgrp(1).OBR:ObservationDateTime.timeofanevent}

To give something like RXR0000000-000000123-20211125105415.xml as the output filename,

Hi all

I'm new to ObjectScript and I've been experimenting the correlate method of %XML.Reader to convert an XML file I've loaded into its corresponding class. But, I have found that I am not getting all the child items of an element in a List contained within the converted class, only the last item.

The XML file content is as follows:

I programmed some server command by my own. That server commands worked fine for a long time.

Suddonly I received 

Studio Action "Attempted Edit" not supported on 127.0.0.1:57772[CTAE01]

by using one of my server commands.

There is an explanation:

Error running command vscode-objectscript.serverCommands.contextOther: Running the contributed command: 'vscode-objectscript.serverCommands.contextOther' failed.. This is likely caused by the extension that contributes vscode-objectscript.serverCommands.contextOther.

Hello,

I don't know if the title is accurate enough. I have a legacy code that I need to optimize. It's a routine written in objectscript. It accepts 4 parameters and runs 6 nested FOR...$ORDER reading a big global.

The thing is when I run the routine the first time it takes around 60 seconds to run. If I run it again it takes 5 seconds. If I wait around 6 to 10 minutes to run it again, it takes 60 seconds again, but if I run it every 1, 2, 3... minutes it still takes only 5 seconds to run.

Hey everyone.

I was wondering if anyone had come across a way of reformatting ObjectScript within VSCode.

I have the various Intersystems Extensions installed (InterSystems Language Pack,  InterSystems ObjectScript,  InterSystems ObjectScript Extension Pack,  InterSystems Server Manager) but a formatter does not seem to be something included within this variety of extensions.

I am receiving the following error in my buisness operation:

ERROR <Ens>ErrException: <UNDEFINED>zGo2+181^mb.MbMainOperation.1 *tSC -- - registered as '-' number - @' set pResponse = ##class(mb.MbMessageResponse).%New()'

From what I understand, the problem occurs in the generated int file mb.MbMainOperation.1 in the method zGo2, with the offset of 181 lines, and the variable in question is a local variable tSC.

However, the line where the error occurs does not refer to tSC in any way

If I open a terminal and type the following commands, sc is an error:

set validator = "sc = ##class(%Library.Numeric).IsValid(""BLAH"")"
set @validator
write sc

At the end, when I write sc I get:

0 L'BLAH9
             DOCXT010,#e^zIsValid+1^%Library.Numeric.1^1e^^^1

However, if I call the following class method using the arguments "%Library.Numeric" and "BLAH", sc is undefined

I am trying to figure out the best ObjectScript analog to mimic, more or less, the %RCOPY functionality. What would be ObjectScript  method(s) if any to copy a routine from the current namespace to another one and compile it there?

Modifying %Stream contents

I have a %Stream that I want to insert some text into the middle of.  I create a new stream called pNewContentStream from the original stream, then I do a MoveTo in pNewContentStream to get to the byte position I want to insert into but when I do my Write, my pNewContentStream gets obliterated with only the text that I wrote, the original content goes away and all I'm left with is my Write text.

Portal's category.

Hello,


I’m looking for a way to find out which category of portal a connector belongs to.
I looked at the class ‘Ens.Config.Production’ and ‘Ens.Config.Item’ but without success.


An idea about the ‘ObjectScript’ code to design?

Best Regards.

Hello,

I'm experiencing a recurrent problem that I haven't found the way to solve, so I'm coming here with the hope somebody can give me a new approach.

To make it short: we are creating categories on-demand to be able to place the maximum numbers of workers in memory, avoiding the limits established by system categories. But from time to time, one of this creation fails and system is no able to start the queue. The error we are getting is:

I am executing the command:

      set fileComp = ##Class(SYS.Database).FileCompact(obj.Directory, freeSpace, .actualFree)

      where obj.Directory contains the location of the current database

This executes correctly. However, the resultant OREF object does not contain any displayable properties but rather is of the value:

       "0 "_$lb($lb(380,,,,,,,,,$lb(,"%SYS",$lb("e^zFileCompact+38^SYS.Database.1^1","e^^^0"))))/* ERROR #380: Completed but skipped some blocks, details recorded in the console log. */

I have a terminal script that queries sys.process' and then parses the results writing to a logfile. As part of the processing of the results, each row of the result set includes an element from the static string.  But I am not clear on the scoping of the static string. The write statement sees the static string as undefined. What I want is something to the affect:

     set statStr = "aa|bb|.."

   set sqlStatement = xxx

   set tState  = ##class(%SQL.Statement).%New()

   set qStat   = tState.%Prepare(< sql statement> )

in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?
