#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.

Hey everyone.

I have a process where I create a new %Stream.FileCharacter object, specify the filename (including it's path), write data to the stream, and then save. However for some reason, if the user account does not have write access to the directory, the %Save method is still returning true even though it was unable to actually write the file to the folder.

The location is a UNC path, and I'm wondering if this is tripping me up?

Hey I am very new to Intersystems Objectscript and I am trying to find a way of extract 4 digit numbers from a stream.

I have a stream full of results

2334

3434

5543

4334

And I am trying to remove each 4 digit grouping from the stream.

I have tried the following for loop

for i=1:1:$length(result) {

set curr = $extract(result, i)

write !, curr

set count(curr) = $get(count(curr)) + 1

}

Unfortunately the loop extracts one digit.

%XML.Reader Limitations

Hi all,

Are there limitations to the size of a file or stream that %XML.Reader will parse?

I am trying to parse a large, 573MB, XML file using either the 'OpenFile' or 'OpenStream' methods, but both return errors.

When I try to use the 'OpenStream' method I get a 'ERROR #6301: SAX XML Parser Error: input ended before all started tags were ended' error',

and when I try the 'OpenFile' method I get a 'ERROR #6301: SAX XML Parser Error: <STORE>'.

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> )

Subscript with double quoted

Hi Team,

I would like to save the array subscript with in double quotes

eg sub1=111,sub2=444 (these values are dynamic)

set array(sub1,sub2)=""

It will be saved as array(111,444)=""

but I want to save it as array("111","444")=""

I am trying to save it from the class like """"_sub1_"""" but its not displaying as expected.

Kindly do the need full.

Thanks in Advance

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

We have a function that was written for us that allows us to create text files for logging certain aspects to the OS using %Stream.FileCharacter. We had no issues with this until we moved from AIX to Red Hat.

Now it seems the 1st time the function is called, and the file is created the permissions seem to be correct on the file. But as soon as we attempt to write another line to the file using MoveToEnd() it seems the permissions are changed on the file. I have been able to narrow the issue down to the MoveToEnd() by calling the function from different users.

Hi Community,

Is there a way to call HL7 Data transformation directly from Business service without using Rule functionality in the production

In this scenario i need to call a data transformation in directly in business service and give the transformed message to Business operation

Please share if you have any ideas to implement this.

Thanks,
Smythee

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?

Good day, I would like to find out the size of Caché ObjectScript variable in order to guarantee that my program will not leak, equally in terminal and Caché globals. For example how huge number I can store in that variable ? And what happen in Caché when variable will leak ? How is this behavior treated? (how much memory is reserved for common variable?)

Thanks in advance for your answers.
