chaque client a 0 ou un compte
chaque compte peut avoie de 0 a plusieurs credit aur les articles

alors jai utiliser un trigger after insert et before update sur article
que si le clients veut faire un credit sur cette article
alors le triiger me fait une insertion sur la table credit
el la table credit atraver un autre trigger mise ajour le credit total de clients

jusque la toutes et bon

mon problème c est lorsque il un versement d'un client

je veut faire la mise ajour suivante

si le versement = crédit totale donc
crédit totale = 0 est dans la table crédit détaille je remis tous les enregistrement de crédit détaille seront remise a la valeur 0;

mais si le versement < crédit totale
je veut 1 : crédit totale = crédit totale - versement
2 : il commence par le premier enregistrement du crédit détaille
si le versement >= crédit détaille alors
versement - crédit détaille et il remis cet enregistrement a 0
et versement sera égale a versement - crédit détaille;

si le versement < crédit détaille alors
crédit détaille - versement et il remis cet enregistrement a reste
jusque ’a versement sera = 0

j'ai fait une procédure avec un curseur

bonjour

j'ai bien peur que les curssors en MySQL ne prend pas en charge les mise a jours de plusieurs lignes des tables

Code:

http://dev.mysql.com/doc/refman/5.7/en/cursor-restrictions.html

y'a t'il d'autre méthode ou un autre moyen pour remédier ce problème ????
