Oracle SQL Where clause to find date records older than 30 days
I want to find records in a (Oracle SQL) table using the creation date field where records are older than 30 days. It would be nice to find records using a operators like > but if anyone can suggest quick SQL where clause statement to find records older than 30 days that would be nice. Please suggest Oracle syntax as that is what I am using.
SELECT * FROM YOUR_TABLE WHERE creation_date <= TRUNC(SYSDATE) - 30
SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.
Depending on your needs, you could also look at using ADD_MONTHS:
SELECT * FROM YOUR_TABLE WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)
