I'm not sure how to actually interact with the result set I get from doing something like this. I want to return something like:

[{"field1":1, "field2":2}, {"field1":2, "field2":10}]

I'm finding it very difficult to get it in this format, since %Print appends a newline onto the end of the {} object it prints.

Here's the closest I've gotten:

How to convert SQL persistent classes to JSON output - I have tried 1 option but appears to be very lengthy process.

I have many other SQL storage's defined and have to expose them as well to JSON. Can anyone please suggest a better approach.

My column names usually match with my Json properties.

My User.TestClass is the class with GetJsonList() as my method to return /output JSON formatted data.

The Code tried and SQL storage structure are as follows -

Hi everyone, I have and Zen Mojo application, it's all working but I have some doubts about what is recommended to use: There is some reports of employees, for example, and actually I'm using some plugins : "Excelent export" to generate Excel reports and "jspdf" to generate PDF reports in client side.

I have an REST service, that receives the request, process and returns JSON, after client side receive the response it's processed.

- This can be slow/bad in applications with large data?

- It's better/recommended to use ZenReports even with ZenMojo applications?

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

Binary Support in JSON?

I'm working on a REST service which will include a binary stream as a request property. I'm currently encoding the stream as BASE64 and passing it as a string value, but I was wondering if there is anything in the Caché JSON support that may be a better fit for encoding this data? Thanks Chris

MessagePack support

MessagePack is a binary-based efficient object serialization library. It enables to exchange structured objects between many languages like JSON. But unlike JSON, it is very fast and small.

Any chance of adding support for MessagePack?

I am making a FHIR request against Epic, in when I get the Response back using "fromDao" I am extracting the stream into HS.FHIRModel.R4.Patient. However, the patient's name comes back as name within a list that references HS.FHIRModel.R4.SeqOfHumanName.

  • How do I extract the name from HS.FHIRModel.R4.SeqOfHumanName?
  • Do I have to then do another "fromDao" to pull the list into string format?
  • How do I navigate around the lists that are in a FHIRModel response, to extract the string values?

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class.

Hi noble devs!

Just building a simple frontend->JSON->IRIS backend story, and figured that IRIS while importing via %JSON.Adaptor wants JSON fields to match property names, meaning even should match the case. Like:

{ name: "John", 

surname: "Doe"}

will have issues while saving the dynamic object to a class Sample.Person with:
