From 18a040773c389de7be48111efc0f3cf7252ffc68 Mon Sep 17 00:00:00 2001 From: Boris Kolpackov Date: Tue, 20 Sep 2011 11:53:04 +0200 Subject: Change query syntax to use . for composite and -> for object pointer access Also make non-inverse query columns act as both an object pointer and a normal column.
