Re: JSON

The sql JSON is Java based and I have find more issues with java on the iseries...

Not as far as I know it isn't (and I see no evidence of the JVM being invoked when the JSON functions are used). I think you maybe thinking of the HTTP functions, which do use the JVM.

I'm assuming by "parse" you mean "construct" right? In any case why bother with a third party library, why not just use SQL?

For single values just use:
exec sql set :myField = coalesce(json_value(JSON_OBJECT, '$.error_message' returning varchar(256)), '');

For multiple values use:
select ... from json_table(JSON_OBJECT, '$.', ...);

Subject: [WEB400] JSON

Hello All.

I parse JSON data using YAJL in RPG [1]but can't consume JSON.
Can anybody point me to working open source doing so please.
Scott Klement's article was easy to follow for providing JSON. [2]
One comment on LinkedIn insinuated YAJL is not the way to go but IWS?

Yours sincerely.
