Hello,
I have a date field and I created a Julian date field. I would like to convert the date field into Julian date field as Julian date format. Is that possible? Has anyone tried it before? Thanks!

Hi,

maybe you can try to get the julian date from your date field MYDATE (example) with

TO_DAYS(MYDATE)+1721060

Thanks for your reply, pböttcher. Here is what I'm getting.

2459505 = 10/17/2021 (date)

SELECT TO_DAYS(date)+1721060
FROM `brine_lot`
WHERE `brine_lot`.`id`='%ID%'

Yes, I'm expecting as 21290 as the answer:

10/17/2021 = 21290 (21-Year, 290-10/17)

Hi,

good to know what type you are looking for.

Try

Code: Select all

SELECT (YEAR(date)-2000)*1000 + DAYOFYEAR(date)
FROM `brine_lot`
WHERE `brine_lot`.`id`='%ID%'
