faster in what way?
in performance? i remain unconvinced until i see actual and reliable cpu timings
to code? again, i doubt it, as a good programmer can do it either way real fast
the real test, in my opinion, is in maintainability
most experienced develoipers will tell you that the job of the database is retrieval, and formatting should be done in the front end application
this becomes painfully clear if you've ever worked in an organization where changes to working queries have to be vetted and approved by a separate part of the systems department, whereas changes to the app proceed without this bottleneck
(at least, that's what i used to tell developers when i worked in the bottleneck, er, i mean, database section)
