Re: JSON DS & Data-Into

This is not perfect but mostly works fo me.

Dcl-s fileName Varchar(256) Inz('/Home/Paris/json/Test.json');

Dcl-ds jsonDoc Qualified;
count_documentHistoryEvents Int(5);
Dcl-ds documentHistoryEvents Dim(100);
Type Char(20);
Date Char(28);
Description Char(50);
ParticipantEmail Char(50);
ActingUserIPAddress Char(50);
End-Ds;
count_particiapants Int(5);
Dcl-ds participants Dim(100);
EMail Char(50);
name Char(50);
End-Ds;
status Char(20);
documentKey Char(50);
End-Ds;

// Load JSON Document into DS
Data-Into jsonDoc
%Data( fileName
:'Case=Any Doc=File countPrefix=count_ allowmissing=yes')
%Parser('YAJLINTO');


Note that the DS are nested in the main doc. I added count fields so that you can determine how many elements were supplied. I couldn't be bothered to fit your son into definition specs so I stuck it in a file.

I had to use allowmissing=yes because there appear to be some fields missing from the document and I didn't have the time to work out which ones and to add the count fields - but that would be a good thing to do as allow missing is a dangerous weapon.

Hopefully someone can help me with the various DS definitions and the necessary parameters on the Data-Into command.

This is my first experience with JSON as the web guy asked if we can read it or does he have to create another flat file.

This was partially working when I first put together a test pgm using Scott's YAJL and the various subprocedure calls to process JSON. I got the Data-Into PTFs installed (7.3), switched the parser to YAJLINTO and now I'm realizing that my JSON document is complex. There are three JSON "objects" or data structures in the incoming document. It doesn't matter if I have to process the document three times or can do it all once.

The document looks like this:

{"documentHistoryEvents":[{"type":"Created","date":"2019-04-01T20:33:13.485564Z","description":"Created by external_web_esig@xxxxxxx","participantEmail":"external_web_esig@xxxxxxx","actingUserIpAddress":"66.194.20.120"},{"type":"Sent","date":"2019-04-01T20:33:15.048387Z","description":"Sent<mailto:external_web_esig@xxxxxxx%22,%22participantEmail%22:%22external_web_esig@xxxxxxx%22,%22actingUserIpAddress%22:%2266.194.20.120%22%7d,%7b%22type%22:%22Sent%22,%22date%22:%222019-04-01T20:33:15.048387Z%22,%22description%22:%22Sent> by external_web_esig@xxxxxxx","participantEmail":"external_web_esig@xxxxxxx","actingUserIpAddress":"66.194.20.120"},{"type":"Viewed","date":"2019-04-01T20:33:40.774774Z","description":"Viewed<mailto:external_web_esig@xxxxxxx%22,%22participantEmail%22:%22external_web_esig@xxxxxxx%22,%22actingUserIpAddress%22:%2266.194.20.120%22%7d,%7b%22type%22:%22Viewed%22,%22date%22:%222019-04-01T20:33:40.774774Z%22,%22description%22:%22Viewed> by test@xxxxxxx","participantEmail":

There's a documentHistoryEvents, participants, and an unnamed object. It's formatted correctly as I had the web guy show me using one of the online formatters.

My Data structures and code are defined as follow:

Dcl-ds documentHistoryEvents Dim(100) Qualified;
Type Char(20);
Date Char(28);
Description Char(50);
ParticipantEmail Char(50);
ActingUserIPAddress Char(50);
End-Ds;

Dcl-ds participants Dim(100) Qualified;
EMail Char(50);
name Char(50);
End-Ds;

Dcl-ds DocStatus Qualified;
status Char(20);
documentKey Char(50);
End-Ds;

Dcl-s ResponseStr VarChar(16000000);

// Load JSON Document into DS
Data-Into documentHistoryEvents %Data(ResponseStr:'Case=Any -
Doc=String ')
%Parser('YAJLINTO');

ResponseStr has the JSON loaded from a website using an HTTP call. I've tried processing just the documentHistoryEvents document using combinations of path, allowextra and countprefix options, but I keep getting RNX0356 reason code 5 when executing. I understand the layouts of the DS should match the JSON fields but not sure what to do with multiple documents and an unnamed document.
