I could use some help with some Oracle syntax. Below is statement in MS SQL and I would like to do the same in Oracle. I'm not sure what function in Oracle is equivalent to CASE and is usable with comparison operators? I know DECODE can be used for equal values, but what can I use for greater than and less than conditions? I've looked at the Oracle documentation, but have come up short. As well any suggestions for DATEADD and DATEDIFF? Any help is appreciated.
Thanks!

If you are on ORACLE 8, there is CASE function available. Otherwise you will have to use DECODE and SIGN functions.
