How to determine SQL Server 2008 or above

Question

I need to determine programmatically if the database supports the Geography data type and Spatial indexes. These features were introduced in 2008. I also need to determine if CLR is enabled as these features rely on it. What is the most reliable way to do this?

Answer 1

SQL Server 2008 is 10.x

You can use SERVERPROPERTY in SQL and query sys.configurations

SELECT
   PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS varchar(20)), 3) AS MajorVersion, 
   value_in_use
FROM 
   sys.configurations
WHERE
   name = 'clr enabled';

Edit: added CAST
