Hi there,

I had some enquiries refarding thest 2 statement. When I key in the following statment.

SELECT target_date FROM table_1
WHERE target_date
BETWEEN to_date(sysdate,'dd/mm/yyyy')-5
AND to_date(sysdate,'dd/mm/yyyy')-3

no rows selected -- is displayed

However, when I use the next following statement.

SELECT target_date FROM table_1
WHERE target_date
BETWEEN to_date(sysdate,'dd-mm-yy')-5
AND to_date(sysdate,'dd-mm-yy')-3

I am able to retrieve the target_date. May I know why is this so?

SYSDATE is a date, TO_DATE purpose is to convert STRINGS to date, so TO_DATE on a date is wrong.
