Re: Request over partition and join - Mailing list pgsql-novice

Answering to myself for the record:

[code]
SELECT DISTINCT ON (societe,date_ord,numero_ordre,libelle)
   ligne_ordres.id,societe,date_ord,numero_ordre,libelle,
   SUM(CASE
     WHEN operation_id!=2 AND operation_id!=21 AND operation_id!=23 THEN
       quantite
     ELSE
       -quantite
     END) OVER w AS pqte,
   SUM(CASE
     WHEN operation_id!=2 AND operation_id!=21 AND operation_id!=23 THEN
       prix_brut
     ELSE
       -round(quantite*cumpb,2)
     END) OVER w AS pprix_brut,
   SUM(CASE
     WHEN operation_id!=2 AND operation_id!=21 AND operation_id!=23 THEN
       frais
     ELSE
       -round(quantite*cump,2)+round(quantite*cumpb,2)
     END) OVER w AS pfrais,
   SUM(CASE
     WHEN operation_id!=2 AND operation_id!=21 AND operation_id!=23 THEN
       prix_net
     ELSE
       -round(quantite*cump,2)
     END) OVER w AS pprix_net
FROM ligne_ordres INNER JOIN titres ON ligne_ordres.titre_id=titres.id
INNER JOIN operations ON ligne_ordres.operation_id=operations.id
WHERE (date_ord<='2011-03-01' AND societe='WHATEVER'
   AND ligne_ordres.id BETWEEN 12 AND 3690)
WINDOW w AS (PARTITION BY societe,date_ord,numero_ordre,libelle)
ORDER BY societe,date_ord,numero_ordre,libelle,ligne_ordres.id
[/code]

Not sure if it is the best way to do it, but at least it works.
