Why can't you use that logic? And come to think of it, I'd rather run this cleanup on the FIRST sunday of the month. So, I can do a trun() at month (to get the first), then substract 24 months. So you will always cleanup on a month boundary.  

Month to month cleanup is always better than on a random date in the last week. What do you think?

Hi  

Can somebody suggest good method to delete all record older than 2 years from the current date. This script will run on the last sunday of each month. I will write the logic for Last sunday in Unix shell but need some idea about the SQL. I can't use some 365+366 or so kind of logic. THis is 9i.
