SQL Tips : Converting SQL Server Date time format

This morning, one of my friend asked me "how to convert SQL Server DateTime format into other format?".

 Example: from this 2010-12-17 (yyyy-mm-dd) format  into 17-DES-2010 (dd-Mon-yyyy) format.

and here's my answer:

SELECT UPPER(REPLACE(CONVERT(VARCHAR(11), GETDATE(), 106), ' ', '-')) AS [DD-Mon-YYYY]

and its worked well
