SQL SERVER – Versions, CodeNames, Year of Release

Just a day ago, while I was discussing one of the project with another outsourcing team lead in India (who is leading team of 100+ programmer and developer) he asked me if I know all the codenames of the SQL Server releases so far. I knew only two code names SQL Server 2005 – Yukon and SQL Server 2008 – Katmai. Once our meeting was over, I could not stop thinking about this question. I search online and very easily I found answer to this question on wikipedia. The full list of SQL Server codenames and release years is below.

• 1993 – SQL Server 4.21 for Windows NT
• 1995 – SQL Server 6.0, codenamed SQL95
• 1996 – SQL Server 6.5, codenamed Hydra
• 1999 – SQL Server 7.0, codenamed Sphinx
• 1999 – SQL Server 7.0 OLAP, codenamed Plato
• 2000 – SQL Server 2000 32-bit, codenamed Shiloh (version 8.0)
• 2003 – SQL Server 2000 64-bit, codenamed Liberty
• 2005 – SQL Server 2005, codenamed Yukon (version 9.0)
• 2008 – SQL Server 2008, codenamed Katmai (version 10.0)
• 2011 – SQL Server 2008, codenamed Denali (version 11.0)

SQL Server 2008 is expected to be release in February 2008.

UPDATE (Oct 2012). SQL Server 2012 was released in April 2012 and the codename of the product is “Denali.”
