Bill not "Dan". :-)
Pretty sure IIF() was added in SQL Server 2012. if you (will) have no need to support earlier versions of SQL Server and/or you will have no requirement to port your code to a different SQL engine then for simple cases, IIF() is (IMO) a simpler syntax than CASE. YMMV and you have to consider your use own cases. But who am I to argue with gurus? :-)
