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;
