Only If the Values are Part of the Table !!!! If Not he needs a PL/SQL Function Returning a Table Type and then He can Select from that Table Type....
My few cents ... :)

When "porting" from SQL Server to Oracle (or many other combinations, for that matter) you need to recognise that you are changing much more than "just" the database. Frequently large parts of the application may need to be replaced -- or even redesigned.
This particular construct might be perfectly natural with SQLserver, but it definitely is not with Oracle -- as you have already noticed, it is not valid Oracle SQL. The following construct, while looking rather "unusual" MIGHT do what you want:
SELECT ... WHERE ... AND values = 'xyz' UNION ALL SELECT ... WHERE ... AND values <> 'xyz';
With this, like almost everything else you will face while "porting" from one database to another, you may want to think twice about what you are really trying to achieve an how you should actually best go about doing it...
