RE: Sort JSON_OBJECTAGG

This worked for me on a test file. You basically pre-sort the file you're reading from, rather than reading direct from the file:

select cast(
json_objectAgg(trim(cast(ID as char(6))) value trim(DESC)
ABSENT ON NULL) as varchar(500))
from (select * from qtemp/tstfil order by desc)


Results:
CAST function
{"1":"TEST 1","2":"TEST 5","3":"TEST 2"}

Here's what I need in the end.
{"3":"Apples", "2":"Broccoli", "1":"Carrots"}

The closest I've gotten is this,
[{"3":"Apples"}, {"2":"Broccoli"}, {"1":"Carrots"}] from this statement.
JSON_ARRAYAGG(JSON_OBJECT(trim(cast(ID as char(6))) value DESCRIPTION ABSENT ON NULL) ORDER BY DESCRIPTION)

From there I just fixed the braces and brackets.

Thanks

It seems that JSON_OBJECTAGG currently does not support an extra ORDER
BY/SORT ... and specifiying a final Order By may be too late.
