I'm switching from ORACLE to MS SQL Server. I was on my way to being certified as an ORACLE Programmer when my company switched their database from ORACLE to SQL Server (thanks to me - I proved the original vendor was not living up to their contract).
In my opinion - SQL Server is WAY easier to learn and work with. I took the Administering an SQL Server 2000 database class and am the only DBA. I'm not having any problems writing jobs, scripts, administering the database, etc. I take the programming class next week. Oracle's SQL and MS SQL Server's T-SQL are basically the same.
I think you'll like the 'simplicity' of SQL Server over Oracle.
