We have recently installed 9i and here is what I was trying to do:

I want to create a view that brings in a column named REQUEST_LOG_DATE which a date/time stamp. I also need another column that will subtract the log date from the sysdate and assigning a value depending on the age of the request.
For example, if the difference is between: 0 and 30 days assign a null value for that record, 31 and 60 days assign a value of 30 for that record, 61 and 90 days assign a value of 60 for that record, 91 and 120 days assign a value of 90 for that record, 121 and over days assign a value of 120 for that record.

This is how I started out but didn't get far:

decode((round(sysdate - REQUEST_LOG_DATE)),(between 0 and 30),null,(between 31 and 60),30,null) Received on Wed Dec 31 2003 - 09:51:01 CST
