Drizzle doesn't have FRM files and hasn't for several years (since 2009 IIRC). If you were going to do VIEWS (and materialized views at that) in Drizzle, there's a couple of ways you could approach it and we should discuss how to do that the right way rather than the way it's done inside MySQL. -- Stewart Smith
