RE: converting case in sqlserver to oracle

I believe Oracle 9i supports the CASE syntax. Otherwise, you're probably looking at using some sort of DECODE conbination.

Or, I've found a lot of SQL Server queries are overly complex because SQL Server didn't support user-defined functions. I was able to simplify a lot of queries when moving them to Oracle by defining a few functions to replace parts of the query.
