J'ai modélisé une base de données (CMS pour challenge personnel), 14 tables avec de nombreuses contraintes de clés étrangères (notamment 1 -> 0,1 relations) et Je vais remplir les tables avec des valeurs par défaut.Initialisation de la base de données (avec de nombreuses contraintes 1 ... 0,1) avec des valeurs par défaut
Le défi pour moi est de détecter une sorte de méthode dans quelle séquence remplir les tables, pour éviter les erreurs lors de l'insertion.
Existe-t-il une méthode distincte pour cela? Je continue d'avoir des erreurs dans le script d'initialisation à cause d'une mauvaise séquence!
Courte description: Une page peut contenir une entité de contenu, mais pas nécessairement. Un contenu peut contenir une ou plusieurs sections, mais pas nécessairement. La page et le contenu peuvent exister de manière autonome. Une page peut faire partie d'une communauté dans un meny ... etc. J'utilise framework d'entité comme mon orm et j'ai légèrement modifié edmx, donc je ne reçois pas de référence quand je fais une relation un-> beaucoup, f.ex.
Voici mon modèle et les relations:
Voici mon script d'initialisation de tout l'utilisateur et d'autres tables juste pour aller avec le codage de la procédure de connexion:

Des exemples de données, les résultats souhaités et un script simplifié aideraient vraiment à expliquer ce que vous essayez de faire. –
En général, vous devez partir de l'entité la plus "interne", celle qui n'est pas référencée par d'autres entités (ex. A), puis en n'insérant que des entités (B, C) référençant uniquement les entités que vous venez d'insérer (A), et ainsi de suite. – Wallkan
Ça pourrait être difficile. Supposons que AB est une référence croisée pour A et B et que la vapeur d'entrée contient des paires (a1, b1) (a1, b2) ... Le script qui lit le flux et remplit A, B et AB doit vérifier et insérer conditionnellement toutes les données 3 tables. Pouvez-vous être plus précis sur le schéma DB et les entrées? – Serg
