While SQL Server includes an amazing array of built in functions and procedures, one that's always puzzled me is the lack of a simple function to convert a database compatibility level to a SQL Server version ie: how do you know that 110 was SQL Server 2012?

One of the tools in our free SDU Tools collection for database developers and DBAs is SQLServerVersionForCompatibilityLevel.
It's a simple function that takes the compatibility level (an integer), and returns the name of the SQL Server version (a string) as you can see in the main image.
