WHERE CURRENT OF invalid for view cursors

Changed in: 2.0

Description: In versions 2.0.x, positioned updates and deletes using WHERE CURRENT OF are no longer possible for view cursors, due to some problems that could make such cursors unreliable. This restriction will be lifted again in Firebird 2.1, which has an improved validation logic for views.
