I see you're using the following syntax:
! SELECT * FROM a INNER FORCE JOIN (b INNER FORCE JOIN c ON (b.ref =
c.id)) ON (a.id = b.id);
The only place I've seen that before is MySQL straight_join feature: http://dev.mysql.com/doc/refman/5.0/en/join.html
My first though at the time was "what a lame optimiser if I'm to tell
it where not to reorder joins", but perhaps this was because the
option there, IIRC, could impact the results...
I guess I'm not going to like it, but nonetheless, if we're going to
support the feature, what about calling it the same as MySQL, unless
the standard has something to say?
