Vern,
Thank you! That works perfect...
However, the API developer added a parameter to the call that causes it to
respond with element names. I was going to try something new, but it was
too easy to complete the task with DATA-INTO.
Thanks to all! I learned something.
Greg

You need to add with chg at the end of the statement - there might be
other commit settings one could use, but that's what I and others here have
used.
Good luck

Vern,
That's what I tried... I get an SQL Error: SQL State 42926, Sql0443 LOB
and XML locators are not allowed with commit(*none).
I can't find how to overcome that.

Subject: RE: JSON un-named arrays
Hi Greg
As for how to do this with stream file, if you mean how do you process a
JSON file in the IFS, there is an SQL function that can pull the JSON file
in to be processed - it's used where Daniel has "insert your json here" -
here's an example - JSON_TABLE(Get_CLOB_From_File(:xmlFilePath),

Thanks Daniel!
With this API, the Data portion is only dynamic based on my call to the
REST web service (I passed the value in the "fields" as a parameter to the
web service).
I'm willing to try something new (and I like Run SQL Scripts)...
Just curious how I would use this with a stream file on the IFS? I like
to save my latest response on the IFS.
Thx,
Greg

Hi Greg,
I don't know, if it helps, but you can walk the whole JSON document with
SQL without problems.
select *
from json_table(
'{...insert.your.json.here...}',
'lax $'
columns (
records integer path '$.records',
fields varchar(1000) path '$.fields',
nested path 'lax $.data[*]'
columns (
trano integer path '$[0]',
ref varchar(50) path '$[1]',
duedate decimal(8, 0) path '$[2]',
name varchar(50) path '$[3]',
amount decimal(10, 2) path '$[4]'
)
)
) as json_doc;
As you can see, the named parts are referenced by ".name", whereas the
"unnamed" JSON elements have no named reference, but only the "[index]".
The nested path reference is the JSON equivalent of an table JOIN.
Of course - if the "data" part of the JSON is dynamic, and you have to
detect the columns be the "fields" element, it can get a but complicated.
But even then, you can first split the "fields" list into its elements, an
then construct a dynamic SQL to extract the "data" parts.
So from my POV - SQL is often the easier solution - especially because you
can test it with Run SQL Scripts until everything is "perfect".
HTH and kind regards
Daniel
