Powerbuilder utilisé presque exclusivement pour les applications de base de données à forte intensité, il peut être plus avantageux d'utiliser votre système de base de données pour cela.
Si vous utilisez Sybase SQL Anywhere, un moteur d'exécution qui est livré avec Powerbuilder, vous pouvez utiliser le sa_split_list
system procedure
Ou vous pouvez construire votre propre. Le PFC comprend cette fonction vous pouvez utiliser
