Experts

is there a way to f开发者_StackOverflow社区ind out the version of SQL express installed on my machine?

Connect to it using SQL Server Management Studio (or some other sql client) and run:

SELECT @@VERSION

This will give you detailed information about the version you are connected to. An example from my installation:

Microsoft SQL Server 2008 (RTM) - 10.0.1600.22 (X64)
