Re: SELECT with LEFT OUTER JOIN ON

Instead of:

FROM formation f, ref_unite_de_duree u, ref_unite_de_duree u1
LEFT OUTER JOIN ON (f.unite_duree_entreprise=u.id
AND f.unite_duree_totale=u1.id)

try:

FROM formation f LEFT OUTER JOIN ref_unite_de_duree u ON 
(f.unite_duree_entreprise=u.id)       LEFT OUTER JOIN ref_unite_de_duree u1 ON 
(f.unite_duree_entreprise=u1.id)

I don't know if the results are that you expect but the sintax, I think 
is correct !
