Today's challenge is about decompressing input that is compressed in an experimental format. In the format, markers indicate how much time a number of characters need to be repeated.
Hello, first of all thanks for your time reading this question,
We would need some help, we would need to delete a %GlobalBinaryStream which is a variable called "pOutput" which is being sent from a REST Service to POSTMAN
We have developed a REST Operation. We wonder how could we face that String do have a character limit.
We just need to convert httpRequest.HttpResponse , which is a stream , because $isobject(response.Data) returns 1; which has a JSON inside it, and we need to convert it to a Ens.Response.
This response is structured as same as the JSON's properties:
It is easy to receive JSON representation or dynamic Array from %ListOfDataTypes:
set l=##class(%ListOfDataTypes).%New()
do l.Insert("a")
do l.Insert("b")
do l.Insert("c")
set arrStr=l.$toJSON()
zwrite arrStr
set arr=l.$compose([])
zwrite arr
How to make backward conversion? How to receive %ListOfDataTypes from dynamic Array an JSON string?
I am new to Cache and I am trying to convert a JSON string (msgdata) that contains a JSON payload to an object to be saved into a Driver. Entity table. I am running into 2 issues and would appreciate any help:
1) It seems that when the 1st element of a list within the payload (Choices) is an empty string, after I call %ConvertJSONToObject, the obj.%data("payload").Choices contains just 1 empty element, removing the next 3 valid values (10,20,30). The same does not happen if I change the input to [10,20,"",30], in this case it works correctly.
Hi, I want to INSERT a customerID and customerName to a table if the customerID does not exist. Or UPDATE if they've changed their name. I've reviewed the documentation (https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=RS...) and have confused myself with the INSERT OR UPDATE statement. Rather than using two individual statements , is there a way to get it in one?
What I have at the moment doesn't do anything. In fact it errors.
I've seen a few password change posts, but I wasn't 100% sure it was the same process, so I am asking here. We periodically have to change the passwords for a few Cache user accounts across several servers. Is there a process/script to change these passwords without having to go into the web portal on each server? Thanks so much, and I apologize if this was covered in some of the other articles that I've run across. Just looking for the best method.
Currently, I'm working on a project that requires highly dynamic event management. In the context of the Java programming language, my first instinct should be to opt for the "Observer Pattern", which is an approach to managing interactions between objects by establishing a notification mechanism. It allows multiple observers to react to changes in the state of a subject autonomously, promoting code flexibility and modularity. If you are not familiar with this design pattern, check out Wikipedia to find more information about it.
While it's natural and commonly used in certain programming languages as Java and C++, in ObjectScript, it's quite a different story.
SELECT EventType, InitiatedAt, COUNT(*) as cnt
FROM HS_IHE_ATNA_Repository.Aggregation
WHERE EventType = 'LOGIN'
AND LocalDateTime > '2016-02-16 11:00:00'
GROUP BY EventType, InitiatedAt
Consider you need to exclude substring(s) from a string.
I did it with the following snippet:
/// excludes all the substrings from the string
ClassMethod ExcludeSubstring(substr,str as %String) As %String
{
while ($L(str,substr)>1) {
set str=$Piece(str,substr)_$Piece(str,substr,2,*)
}
quit str
}
A few years ago, I was teaching the basics of our %UnitTest framework during Caché Foundations class (now called Developing Using InterSystems Objects and SQL). A student asked if it was possible to collect performance statistics while running unit tests. A few weeks later, I added some additional code to the %UnitTest examples to answer this question. I’m finally sharing it on the Community.
I would like to create a new message of a particular type and append various segments programmatically. I have started with the following snippet. What I am currently finding difficult is to define a segment of a particular segment structure. I would like to append a pid segment of 2.3.1 to my message. I know I could you the importfromstring but I wanted to know whether there was a better way of achieving this.
One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.
Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.
The trick is how you transfer an array to work with into a function.
One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator.
Below you can find a very simple example which illustrates the thing.

The following code snippet outputs message header data in Ensemble. The class method "fetchExecute" runs the process, and the result is stored in the argument "qHandle":
Hey everyone as you may know I am a beginner and I am kindly asking for some assistance in a problem I have been solving. The problem is that I am calling a user defined function within a procedure called occupiedseatsAdj and the compiler comes up with this error.
Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:
Converting between internal and ODBC formats.
Converting between local time, UTC, and Posix time.
Converting to and from various date display formats.
I've been having a blast with the Advent of Code puzzles this year - though I'll be heading into a busy span of time with family soon and will probably drop off toward the end. (At least, that's what always seems to happen - it's a good thing, though!)
Thank you for taking the time to read, understand, and answer this question.
If you needed to convert a message where questions are separated by "|", and the question text is the portion before the ":" and the response is the portion after the ":"; Which way would be the most readable and understandable for other developers?
Input example:
NAME OF SQUAD 1?:ALPHA|NAME OF SQUAD 2?:BRAVO|NAME OF SQUAD 2?:ANSWER THREE||NAME OF SQUAD 25?:YANKEE|NAME OF SQUAD 26?:ZULU
when I look into the "sql statements" ( sql page of the management portal ) I have lots of old statements with a lot of them frozen. many of them are %sqlcq routines (I believe these are the SLQ's I run when testing/running random SQL queries in the sql page. )
I can clearly see where I can click on an individual query and untick an individual query to unfreeze it. or delete it. but thats a painful slow process. I can't see anywhere to delete/change multiple queries
In a development environment, we have added quite a few presentation contexts to the DICOM configurations (the associations). We would need to find a way to export them from this environment to make it easier for us to import them in PRO (and avoid doing it by hand one by one).
to dismount/mount a database, use Dismount() and Mount() methods in SYS.Database class available in %SYS namespace. NB: the database ID is its Directory
You'll find some examples of how to dismount/mount and check if a database is mounted (Mounted=1) or not (Mounted=0), and quickly see all the attributes of a database (via zwrite)
