I didn't know about this functionality. I know it is a 'sharp tool', but what I've gathered out by reading the document is that this only affects indexes, and if I understand the doc, only when the imposter table is created or is used to modify the indexes. What if an imposter table is created at database inception, and is not changed or modified, and only used for R/O queries? Does it become a blunt instrument or is it still a sharp utility knife?
Personally, I doubt I'd ever use this. I've never required knowledge of what the index is beyond faith in knowing that the engine knows what its doing, or, needs to get updated periodically. (I know of different methods of indexing in different engines, but, never needed to know which is used or implemented) On Wed, Jun 14, 2017 at 8:22 AM, Paul Sanderson < sandersonforens...@gmail.com> wrote: > Can you create an imposter table on a view.
