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.
The demo is based on the raw class descriptions. The data classes used are Address, Person, Employee, Company For a more attractive demo, a JSONtoString method by ID was added.
Forgive my lack of understanding, but I am working on a vendor created Cache database and the indexes specified in the classes for ODBC connections are not working. A few of them are created, but of the 50+ classes we have, only a handful of them are created when the class is compiled, yet no errors occur.
In the system that I work, I came across an iterator pattern that uses the %Resultset library without performing the close after executing the query. Does anyone know how to say what are the impacts of not performing such a procedure?
If you have any model of iterator pattern made in caché to recommend as a good example, I will be grateful hehe :D
I’m pleased to announce the 0.9 release of the ObjectScript extension for Visual Studio Code. Earlier this year I announced that InterSystems would be joining the community in evolving this already popular tool. Since then, we have been hard at work solidifying the code base and building a slew of new features.
I have come across several cases where I need to set a Date filter to send only send any admit/scheduled date past a certain point. We have a couple different date comparison functions but none looking at the true date. Most of them are date + 15 or etc. Does anyone have a good date function they have written to say if x > 20170102 ?
Error management on InterSystems languages has been evolving along time. Next, we will show the different implementations and why you should use the TRY/THROW/CATCH mechanism.
I was able to define ECP connection in Installer class that I run when I build docker image for my Docker IRIS application. Now I start to use Amazon ECS and Autoscaling. When a new instance is created and it runs the IRIS container, I want it to "register" as an Application server on the remote database server. What code can I execute to add an ip address as an Application Server?
Just like the title, I want to do code version control. I don't want to change CLS at will, but I don't want to use MakeClassDeployed, I just want to set the cls or mac to read-only and uneditable state。Does CLASS have such property?
We are using Ensemble and I added some debug logging that writes to a global and recompiled the class in Studio. However, when we send messages, the global is not populated. I have recompiled, removing the checkmark to keep the generated code so that there is only one .INT file and I verified that the code is present in the .INT file.
My question is, do we need to stop and restart the Ensemble production in order for these changes to take effect? Do I need to stop and restart the business operation that calls this piece of code? Is there something else I may have missed?
Since cache is an OOP language, how can I create 2 methods with the same name but different parameters? Right now when I try that I get a compile time error!
Element name conflict [80670005] : Method mymethod
Can anyone please explain me how to remove trailing squares from the text field (String). Trailing squares is a white space ?
I tried different things like Ltrim, Trim from sql query side and also from object scripting side something below.
If Address1 set Address1 = $ZSTRIP(Address1,"<>P,<>C,<>W") If Address1 set Address1 = $ZSTRIP(Address1,"$C(9), $C(32), $C(160)") If Address1 set Address1 = $ZSTRIP(Address1,"*W,*C")
We have a vendor that every couple of days will just stop transmitting messages, but still hold the TCP/IP connection open. No matter how many times we troubleshoot and talk with them, they don't seem to think its an issue with system. Normally if I just restart the service it will get the data flowing again.
During my search for a snapshot of a persistent object, I met a feature that I would like to share as it could be useful in some special situations. My trigger was to have a before- and an after-image during unit testing.
Now I want to return a large amount of data to the front end. The string length has reached 40000 +, and the returned data needs to be encrypted by AES + Base64. I can convert the string into a stream. AES can use the AESCBCEncryptStream method to encrypt, but Base64 has no stream method。Anyone who get the solution would you kindly share the solution please。
The offer of ZPM is growing daily and the short names and acronyms of the offer are sometimes hard to understand and also hard to type with my lazy fingers.
So I decided to have
a listing with the descriptions from the repository,
It would be interesting if there is some recommended documentation about best practices using Healthshare for interoperability.
Also, some how-tos or frequently asked questions about ObjectScript.
Or event better, if there are experienced developers who would like to share some common habits on their work with Studio / ObjectScript, which are valuable to do the developing work better.
For example, How to get the XML of a class and write it into a REST operation:
t's also an example for a customized command extension (ZZJSN) in Caché & IRIS
This is the Caché version for fast JSON formatting but it also works in IRIS. Requires package ZPretty To allow parallel existence in IRIS this is named ZZJSN
