Simple, short and crisp - I would like to say about TSQL enhancements within SQL Server 2008. You may already aware about what's new and how best you can take advantage within your code, most of the Developers would agree about IntelliSense functionality that supports (gives you advantage on) frequently...
As usual the new release of SQL Server version 2008 had few changes from 2000 to 2005 and as usual this control-of-flow sequence should occur in order to take advantage of performance with transaction/rollback advantages.
