The example returns the JSON Document as a CLOB Variable, while you defined a CLOB_FILE.
You may try it with a DBCLOB_FILE.

You are sure, your job environment is not CCSID 65535 or may be the data in your table are CCSID 65535.

Try to explicitly cast your JSON Data to UTF-8 in SQL, but I assume it will not work either. Data without CCSID (or CCSID 65535) cannot be converted.

I Found this link suggested changing to DBCLOB SQLType but now I Can't set
the _name, _nl, etc. They compile as undefined.

Thank you.

Select ... INTO can only handle a single return value/row!

In this way you should build the complete JSON document within a
single SELECT statement and write the result into the IFS.
For complex queries use common table expressions (CTE).
In the first (few) CTEs generate the raw data that must be
included in
the
JSON document.
In the next CTEs build successive the JSON data, starting with the
lowest
level and then merging the result of these CTEs in the next CTEs ...
until
the complete JSON document is built.

... on the other side it is possible to append data to an IFS table.
You have to change the _FO value to SQLAPP (=Append). After having
changed
the File Operation, new data is added to the end of the IFS file.

Great! Thanks! That did work. It only allows me to fetch the
first
row
to
dump into the IFS file, which makes sense to me.

How could I include multiple JSON messages / 'rows'? Someone
approached us
about doing ND JSON, which might be what this would be. I'm not
sure
to be
honest.

Any thoughts?

Outfile must be a CLOB_FILE CCSID 1208.

DCL-S OutFle SQLType(CLOB_FILE) CCSID(1208);

Subject: JSON_OBJECT and Writing to IFS

Anyone have any luck writing the encoded JSON out to the IFS like
we
have
done with XML using sqltype(xml_clob_File) and Select-ing into
that variable? Do I need to convert / cast the JSON_OBJECT into a
CLOB in
the
SQL? Thanks!

Quick Test...
dcl-s Outfile sqltype(xml_clob_File) ; exec sql Set Option
COMMIT=*NONE,CLOSQLCSR=*ENDMOD,DATFMT=*ISO;

// Prep JSON File
Outfile_Name = %trim('/temp/test.json'); Outfile_NL =
%len(%trimr(Outfile_Name)); Outfile_FO = SQFCRT;

exec sql Select json_object ('upc' value fldupc, 'price' value
price)
Into
:Outfile From PRICING;
