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.
While i am trying to write a data i am getting a error as "<PROPERTY DOES NOT EXIST>zFile+15^User.zKQRest.1 *value,%Collection.ListOfObj" but there are values stored in it. How can i break it write it separately.
I have a list of %Library.ArrayOfObjects . Each of list elements has some properties. I have to sort list by one of its objects properties. Is there a predefined method to doing that? (quicksort maybe?)
I need to find out if it is possible somehow to receive actual linux TIMESTAMP for example with $NOW() or other functions. I was trying to recalculate it with $NOW() function, but without success. I would like to simulate Redis TIME command in COS.
My tryings:
USER > set time = $NOW()
USER > w (($PIECE(time,",",1)*86399) + $PIECE(time,",",2))

In reviewing the documentation found here, it states that there is an Attributes property. Since this is an array, I was wondering how I would go about traversing through the array to review what attributes are available on the file.
I have some constants hardcoded in my class as parameter values, and those constants are referenced in many places in my module. Now the need has arisen to provide different value for those parameters depending on some context. Is it possible to create some sort of accessor method for the parameter (like it is possible for properties), or do I need to perform a thorough refactoring?
I would like to know how to detect in Caché ObjectScript if data saved in string is number and furthermore, if it's type is integer.
I maybe found a solution:
set value = "44.2d3"
try{ set status = $INUMBER(value,"") if ('$FIND(+value,".")){ w "your variable: '"_value_"' is number and integer" }else{ w "variable is number but no integer" } }catch(e){ w "variable is not number" }
I have a situation where I write a character stream to a file. The file content gets signed and the signature is sent to a service provider together with the file content.
The signing is done using openssl.
This works perfectly on a dev PC, which is runnning Windows and has a little-endian architecture.
The problem is as soon as I do this on the server, which has a big-endian architecture, the signed value is incorrect according to the service provider.
The content is signed using RSA SHA256 with PSS padding.
Is there any way to change a class definition (especifically a query definition during the compilation time)? The idea is: I have an abstract class with a parameter where I will define the ROWSPEC of a query and some methods to populate e temporary table The implementation class will override the parameter, specifying the ROWSPEC of this implementation, and the methods will populate the rows in the same format as the ROWSPEC.
I know how to iterate through the One side of the relationship and for each One iterate through all the various Manys.
What I have been trying to figure out, is the code (I can put into a Class) that will start at the top of the Manys, iterate down and for each of the Manys, pull the associated One.
I can do this with SQL or Globals, but I want to use only Class type code.
Good day, I have this issue. I have global like: ^myglobal(varX) = $LB(var1,var2). I need to delete all globals that have variable var1 in that list same without a need to iterate through all globals and checking their value.
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?)
Here's my issue. I've been using Sample.* globals and packages mapped to another development namespace to realize unit tests. So when I ran it, I notice that I forgot to start a transaction in order to be able rollback it to it's original data.
I assumed that I should use transactions since I was manipulating it's data but I didn't want it to be persisted.
I have a case where I am creating a PDF file from an Encoded String, and I need to transfer this file over to another server. I was wondering since this is PDF file if I could just invoke the FTP.OutboundAdapter within my Object script that is creating the PDF from the encoded string. Is this possible? Does anyone have an examples of using EnsLib.FTP.OutboundAdpater within their Object Script?
I'm doing a REST service for integration between 2 systems. The system that invokes me expects a response object where only one of its attributes changes. It could be something like this:
RESTFormsUI calls %Save() for me, which is great. But I want to set the property CreationDate with the current date for every new record being inserted.
So object callback implementation seems as a reasonable option. I did the following:
When you export the Caché ObjectScript code to VCS (Git, SVN, Perforce, etc) do you export the Storage schema for persistent classes? If so, what are the Pro/Contra?
Looking for a way in which I could possibly pass a flag through a property when performing an Insert statement, on a mapped class.
insert into my.class (serialNumber, modelNumber, myFlag) value ('testSerial', 'testModel', 0) myFlag is not stored in the DB.
The mapped class then calls a legacy routine (MAC) via CodeMode = 'objectgenerator', (Insert method within the 'objectgenerator')
Within the legacy routine, I am setting an index... but I don't always want to set it (multiple inserts, and I will only set the index on the LAST insert)
