just an fyi for anyone using the following logic and thinking it will return the number of days difference as i though.

i was expecting the following results

1, 2, 3, but i was incorrect.

assume current date = 03/25/2024

SELECT
   current date - '03/24/2024' as days1,
   current date - '02/23/2024' as days2,
   current date - '02/22/2024' as days3
FROM SYSIBM.SYSDUMMY1

the results are

1, 102, 103, where results returned are yymmdd format.
