The following are two T-SQL methods that determine which version of SQL you are running. The first one is very short, using the @@VERSION?variable, whereas the longer method makes use of SERVERPROPERTY:
SELECT @@VERSIONSELECT CASE WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '8%' THEN 'SQL2000' WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '9%' THEN 'SQL2005' WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '10.0%' THEN 'SQL2008' WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '10.5%' THEN 'SQL2008 R2' WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '11%' THEN 'SQL2012' WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '12%' THEN 'SQL2014' WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '13%' THEN 'SQL2016' WHEN CONVERT(VARCHAR(128), SERVERPROPERTY ('productversion')) like '14%' THEN 'SQL2017' ELSE 'unknown' END AS MajorVersion, SERVERPROPERTY('ProductVersion') [RealMajorVersion], SERVERPROPERTY('ProductLevel') AS ProductLevel, SERVERPROPERTY('Edition') AS Edition
