Change your session attributes(F13) to date format *ISO instead of *MDY.

OOPS,
My question should be:
WHY does the dates in green screen (STRSQL) show as "MM/DD/YY"???
( I ran the same query in System i nav. and I got ISO dates...)

here is my UDF code.
My dates return as "MM/DD/YY".
What Do I need to put in to have them return as ISO ("YYYY-MM-DD")?


CREATE FUNCTION XYZLIB/NUMTODATE (INNUM DEC(8)) RETURNS DATE LANGUAGE
SQL CONTAINS SQL EXTERNAL ACTION DETERMINISTIC BEGIN DECLARE RTDATE
DATE; SET RTDATE = Date(Substr(Digits(INNUM), 1, 4) concat '-' concat
Substr(Digits(INNUM), 5, 2) concat '-' concat Substr(Digits(INNUM), 7,
2)) ; RETURN RTDATE; END

Thanks so much...

Thanks all ,

I'm testing that right now:
here is what I have:

With tmpfile as (
SELECT ech.hord,
numtodate(polog.poendt) as day_entered,
numtodate(ech.hedte) as day_ordered
FROM xyzlib/pologpf AS polog
JOIN xyzlib/ech AS ech
ON polog.pokord = ech.hord
)
Select count(*) from tmpfile
where days(day_entered) + 30< days(day_ordered)


THIS IS SOOOO COOL!
