Simple concept: How to find SQL Server version ?( + version table for SQL 2008)

[Question]: How do I know what version of SQL I have?

[Answer}:

Run the sql to identify the SQL Server version:

SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel')

, SERVERPROPERTY ('edition')

Or 

   SELECT @@VERSION;

Or look at the Object Explorer at the name of the SQL Server instance (it will be a number in the title):

You will get the version similar to this one: 10.0.4272.0
