The more I dig into SQL Server 2005, the more I like it. There is so much good stuff there from the developer point of view. I’m not a DBA, so I can’t talk about the administrative things that they have done, but the abilities of T-SQL and the things that you can do with it are just amazing.

This (64 lines) statements create a summary of how much I spent in each month in the year (including past months), and it actually made me stare in awe at the screen, proud of my accomplishment (which replace a three hundred lines of cursor based script that did some things that were Not Nice^TM to the database.

Am I made to thing that this is pretty?
