From a71aa2e354599950f4bd464f0f19215f1c581141 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Fri, 12 Oct 2012 11:34:49 -0500 Subject: Make wrong permissions query more efficient This removes the subplan and per-row query in favor of a LEFT JOIN where we look for non-matching rows. Tested in sqlite3 and PostgreSQL.
