Andy Yun cleans up some nested views:

Yeah, that thing was small. But the processing was a horrific case study in T-SQL worst practices. And the architect that created it LOVED nested views (and scalar functions… and MERGE… on Standard edition).

I spent a good amount of effort trying to unravel those as part of my efforts to improve performance, and as a result, decided to create my own community tool to help with unraveling them – sp_helpExpandView.

I also occasionally deal with a group loving nested views and now I’m going to need to use Andy’s stored procedure because tracking that on my own gets really painful.
