Hi Vince-
We are at the latest 10.2.2 patch release, with SQL Server 2008. To be honest, I don't really know other than we always had difficulties registering our spatial views if we created them in the RDBMS first, as the operation would throw an error, either in command line or in the GUI.
I suspected that the system tables weren't handling the Shape column and so we always relied on create_view (hence my disagreement with 'rarely used'). I understand that each storage type has a best practice, but haven't read any documentation stating that when using SQL Geometry views should be constructed via the RDBMS. We'll be performing some more testing and I'll get back to this thread asap.
