I have a requirement to calculate the date - (today - 1 month or 30 days).
I see there are no functions available to get system day - 30 or 60 or etc date.
Let me know if anyone has any idea
Didn't get your exact requirement, below might help you to proceed further,
Now() function will give you the SYSDATE, there are functions like Format and FormattedDate which you can leverage part of your calculation.
