Lots of people still push that idea. As I understand it, SQL Server 6.5 stored execution plans with Stored Procedures and not dynamic queries. I assume that they studied 6.5 in some institutional setting and like most such people I've met, are unwilling/unable to think for themselves and rely on vague memories of outdated training.

Since 7 all queries have their plans cached so there is little reason to go the SP-only route anymore.

I'm at a loss to think of an example where a view would be better than a dynamic query.

The whole industry has done an about-face which I find strange. PCs started as a reaction against the lab-coated mainframers, now the DBAs seem to be placing themselves in the mainframer mindset. A combination of centralized and decentralized processing should beat a strictly centralized approach. Ever wait for a subway (mainframe) and opt for a taxi (PC) instead?

Having both is the best way to move everyone and everything around a city.
