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.

[...] SQL SERVER Versions, CodeNames, Year of Release When I started with SQL Server I did not know all the names correctly for each version and I often used to get confused with this. However, as time passed by I started to remember all the codename as well. In this blog post I have not included SQL Server 2012′s code name as it was not released at the time. SQL Server 2012′s code name is Denali. Here is the question for you – anyone know what is the internal name of the SQL Server’s next version? [...]
