Condition sur 2 champs

j'avais compris que tu voulais récupérer l'un ou l'autre, donc il faut mettre le IF avant le FROM:

SELECT STOCOMMENT as Commentaire, 
if(PAAPRIORITY=1,1,PAADEFAULT) as AutreChose,
...

bonne année à toi et aux tiens!

Oui je veux récupérer PAAPRIORITY si il existe et sinon je récupère PAADEFAULT

as-tu mis le IF avant le FROM?

oui mais j'ai un message d'erreur il ne veut pas de IF

IIF(PAAPRIORITY=1,1,PAADEFAULT) et bien cela me renvoie pour le même article une ligne avec PAAPRIORITY=1 et une ligne avec PAADEFAULT=1
donc j'ai 2 lignes avec les 2 emballages differents et moi je veux l'un ou l'autre c.a.d soit le PAAPRIORITY si il existe et sinon le PAADEFAULT, mais je veux qu'une seule ligne par article pas de doublon.
je ne sais pas si c'est clair mon explication, pour info je ne mets rien dans from on est bien d'accord.
