#ObjectScript

16

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.

Is there any way that I can check the native type of an object script variable? (similar to the typeof check in javascript)

I see that the DynamicArray class uses the type of the variable for its output, I would like to do something similar when I receive a value as an argument to my method.

USER>s var1 = 123 //No quotes, number type

USER>s var2 = "123" //quotes, string type

Hi Guys,
Can you please guide me to get rid of this issue. Please find the image files with this post.

Please let me know, before we are developing an API what are all the setup/Configuration(Apache/web server) need to do in my machine.

If any lead would be appreciated.

I don't know, in XMLNamespace parameter which URL need to use.

Thanks,

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

Hey Intersystems-Developer,

I have already used that and know its possible, but can't find it anymore :(

I need dynamic access on proxy objects. For example:

set key = "lastName"

set name = obj.name

set lastName = obj.key <- Not possible

set lastName = obj.GetAt(key) <- Not possible

How can I get access to that object with my dynamic variable "key" ?

Best regards.

Hi all,

I'm very new to this ecosystem so please bear with me:

I've startted learning online and have installed everything I need. I have VS code and I have most definitely installed the pack (3 packages) needed for working on it with ObjectScript. Even though this is the case I'm running into 2 problems:

1. when I type "class" I only get 4 option for auto complete. no "class with multiple inheritances" or anything of the sort. In fact, no Class at all, only ClassMethod. ClassResponse etc.

I was looking for an easier way to build the FHIR Query String, given the Record Map request that is passed into the DTL.

I built this Function, but when I run a message through it, my Query String that is passed back into the DTL is a Reference Pointer and not the String I am looking for.

I'm wondering how I would go about adding headers to a csv file which has already been created. I am unfamiliar with ObjectScript.

For example if I were to use R, I would simply write..

test <- read.csv("file/path/example/Extract.csv", header=FALSE)
colnames(test) <- c("A","B","C","D","E")

I do not have embedded Python installed either as I would know how to do it in that also.

How could I mirror this in ObjectScript please?

My current create file method:

Outperforming PostgreSQL and MySQL

In a previous exercise, I was able to show the power of Caché.
A medium-designed set of interdependent tables with some GB of data.
URLs cross reference over some million pages resulting in ~3 billion records

Competition was between

  • Caché
  • PostgreSQL
  • MySQL

Criteria were Speed + Storage consumption

Hello,
as i'm trying to develop a operation and its methods (SQL adapter), I'm running into issues when i run my test class.
I have the class i want to test in the very same folder as my test class.
I followed the tutorial in the documentation.
When i run the test class, i get the following message error :

LogStateStatus:0::ERREUR #5002: Erreur Cache: <METHOD DOES NOT EXIST>zTestAdd+1^unitTests.testMyClass.1 *myMethod,Package.BO.MyClass

Here is my test class (heavily inspired bythe documentation :-) :

Here's an easy one for you; before I spend another hour looking for the answer, how do you convert %ArrayOfDataTypes to an array (that could, say, fit into the %session.Data array, or maybe just some array named info()), and of course back again?

NS>s aodt=##class(%ArrayOfDataTypes).%New()

NS>w aodt.SetAt("lcavanaugh","username")
1
NS>w aodt.SetAt("organization","coolcompany")
1
NS>w ##class(%ArrayOfDataTypes).BuildValueArray(aodt,.array)

<LIST>zBuildValueArray+1^%Library.ArrayOfDataTypes.1

Hi,

I have a method that has multiple parameters and is normally used from other classes in ObjectScript. Most of the parameters have default values. Withing the server code that's perfect. In some areas I can call myMethod(,,"sometext") or myMethod(tVariab) and thats fine... I use it as it's required in each place.

But now I want to expose it as a REST service so I need to buld a kind of wrapper., another method in a REST dispatcher class that will receive the parameters in a JSON object and will call the server method already implemented. Something like:

Mass Export DTL

Hi Everyone,

We are trying to migrate old server to new infrastructure and need to sync all the DTL cls from old one to new one. There are hundreds of DTL in system and we tried to export from production but cannot select all at once which might cause some missing classes. Not able to connect to studio or atelier with that server neither. Is there any way that we are able to do mass export from system which will save some effort? Please let me know your thoughts. Thanks.

I am trying to figure out how to send a Page via a HTTP.OutboundAdapter to a URL from Ensemble.

We have a URL that I am able to pass PNo=xxxx%PMsg=xxxx as parameters to send the page to a pager.

http://xxxxx.xxxxx.xxx/Employee/Tools/Paging/SendPage.aspx?PNo=1817&PMsg...

When I send the above URL through a REST client I receive a Response of "SENT".

But when I try to send it through the HTTP.OutboundAdpater I do not get a response.

Hi,

I have the requirement to dump large result sets into files. I am currently using %SQL.Statement and the result set created by it.

The DisplayFormatted is used to write a CSV. The query I used to test does not contain any filters, it is just a select * from a table with 16 million rows.
The file created is 2GB in size. The issue I have is that it takes 8 hours to create this file.

I was just not able to do it.

Error debug from VS

Hi community.

Yes, I know that there is other question "VS Code - debugging doesn't work" that is the same issue, but my IRIS instance is not using IIS.

Some times ago, I could debug without problems, but after some updates of Visual Studio, I get the following error

Failed to start the debug session. Check that the Intersystems server's web server supports WebSockets
