Annexe A. Codes d'erreurs de PostgreSQL

Tous les messages émis par le serveur PostgreSQL se voient affectés des codes d'erreur sur cinq caractères suivant les conventions du standard SQL pour les codes << SQLSTATE >>. Les applications qui ont besoin de savoir quelle condition d'erreur est survenue devraient normalement tester le code d'erreur plutôt que de chercher le message d'erreur textuel. Les codes d'erreurs sont moins sujets à changement suivant les versions de PostgreSQL et ne sont pas sujets aux changements dû à la localisation des messages d'erreurs.

Suivant le standard, les deux premiers caractères d'un code d'erreur dénote une classe d'erreurs alors que les trois derniers indiquent une condition spécifique à l'intérieur de cette classe. Du coup, une application ne reconnaissant pas le code d'erreur spécifique pourrait toujours être capable d'inférer ce qu'il convient de faire d'après la classe de l'erreur.

Tableau A-1 liste tous les codes d'erreurs définis dans PostgreSQL 7.4.29. (Certains ne sont pas réellement utilisés mais sont définis par le standard SQL.) Les classes d'erreurs sont aussi affichées. Pour chaque classe d'erreur, il y a un code d'erreur << standard >> ayant les trois derniers caractères 000. Ce code est utilisé seulement pour les conditions d'erreurs qui tombent dans la classe mais n'ont pas de code plus spécifique affecté.
