MS SQL Server and Sybase are from the same code base. MS bought the code from Sybase (silly silly move on Sybase's part). Version 6.5 of MS SQL Server was basically Sybase with a GUI, 7 is slighly different and 2000 is even more so. However that said MS has maintained pretty much all the previous interfaces for backward compatibility and to make it easy to migrate from Sybase. :-) If you can get on hands a early version of MS SQL Server you basicall can train yourself on Sybase. :-)
