Hello,
I have a problem with a sql request on Postgresql.
It uses 'left outer join' and 'inner join'
Here is my request:
select a.acte_id,a.acte_libelle,a.acte_url_image,a.acte_page,
a.acte_texte,a.acte_marge_texte,a.acte_date,a.acte_registre_page,
commune.commune_id,commune.commune_nom,commune.commune_nom_equivalent,
departement.departement_id,departement.departement_nom,departement.departement_numero,
pays.pays_id,pays.pays_nom, t.type_acte_id,t.type_acte_nom,
r.registre_id,r.registre_cote,r.registre_libelle,r.registre_annee_debut,
r.registre_annee_fin,r.registre_disponible,r.registre_repertoire,r.registre_transformation,
source.source_id,source.source_libelle,source.source_description,
source.source_cote,source.source_auteur,
archive.archive_id,archive.archive_libelle,archive.archive_libelle_recherche,
adresse_id,adresse_libelle,adresse_libelle1,adresse_libelle2,
commune1.commune_id as commune1_id, commune1.commune_nom as commune1_nom,
commune1.commune_nom_equivalent as commune1_nom_equivalent,
departement1.departement_id as departement1_id,
departement1.departement_nom as departement1_nom,
departement1.departement_numero as departement1_numero,
pays1.pays_id as pays1_id,pays1.pays_nom as pays1_nom
from acte a
left outer join registre as r
on ( a.acte_registre_id = r.registre_id )
inner join commune
on ( a.acte_lieu_id = commune.commune_id )
inner join departement
on ( commune.commune_departement_id = departement.departement_id )
inner join pays
on ( departement.departement_pays_id = pays.pays_id )
inner join type_acte as t
on ( a.acte_type_id=t.type_acte_id )
inner join source
on ( a.acte_source_id=source.source_id )
left outer join archive
on ( source.source_archive_id = archive.archive_id )
inner join adresse
on ( archive.archive_adresse_id = adresse.adresse_id )
left outer join commune as commune1
on ( adresse.adresse_commune_id = commune1.commune_id )
left outer join departement as departement1
on ( commune1.commune_departement_id = departement1.departement_id )
left outer join pays as pays1
on ( departement1.departement_pays_id = pays1.pays_id )
and a.acte_id=1;
It is based on the data model that you can find at the following url:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jgenea/jgenea-dao/src/sql/hypersonic/crebas-hsql.sql?rev=1.18&content-type=text/vnd.viewcvs-markup
This request must return only one line but the 'left outer join', there are several
lines.
I think that I don't correctly use 'left outer join'...
Is anyone know how to use it?
Thanks by advance for your help.
Thierry
