From acc52090393384c8e8d1994b32363895d5afb371 Mon Sep 17 00:00:00 2001 From: Pierre Chifflier Date: Tue, 6 Jan 2009 23:31:14 +0100 Subject: Allow plain INSERT instead of procedure If the procedure name specified in configuration is INSERT, than use a regular insertion instead of a stored procedure. This should be used when performance is needed, with a flat SQL schema, to reduce the cost of SQL procedure calls.
