Does that mean the string concatenation operator '+' is a new feature of SQL Server 2008 R2? Was this not possible in earlier versions? I am sure I have done this many times even in previous versions.
Also you mentioned scope resolution operator. There are no further details and the information is almost similar to what MSDN page shows @ http://msdn.microsoft.com/en-us/library/dd206995.aspx. And verify your facts about this too. This operator is available in SQL 2008 (yes non R2 version) too.
