On occasion I've been asked about version of SQL Server I'm running when calling support. To make it a little easier to tell you can launch SQL Server Management Studio and execute the following query on master:
SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')
This should display the full dotted version, servicepack, and version of your SQL installation.
Thank you
very useful
