Hi,
I want to optimize my qerry sql (execution time : 2448 ms) :
SELECT b.idxreseller, sum(a.nbrq), b.namereseller from stat a
,reseller b where b.asp=6 and a.idxreseller=b.reseller and
a.month=date_part('month',now() - interval '1 month') and
a.year=date_part('year',now() - interval '1 month') GROUP BY
b.idxreseller,b.namereseller limit 15;
dns=> \d stat_dns_domaine; Table «public.stat»
idxdxreseller | integer | not nullidxdo | integer | not nullidxd | integer | not nullnbrq | integer |
default0month | integer | default date_part('month'::text, (now() -
'1 mon'::interval))year | integer | default date_part('year'::text, (now() - '1
mon'::interval))
Index : «stat_dns_domaine_idx_idxr_idxrevendeur» btree (idxrevendeur) «stat_dns_domaine_idx_mois_annee_idxrev»
btree(mois, annee, idxrevendeur)
\d revendeur; Table «public.reseller»
idxreseller | integer | not null default
nextval(('idxrevendeur_seq'::text)::regclass)namereseller | text |asp | integer |
Index : «reseller_pkey» PRIMARY KEY, btree (idxreseller)
Thank you
Stan
