Cela ne fonctionne toujours pas et la même erreur se produit. – User358218
Oh désolé, je n'ai pas vu l'organisation de votre base de données. Regardez l'instruction create de votre base de données 2. Vous demandez "not null" sur tous les champs. Et puis vous essayez d'insérer seulement une arrivée avec null à tout le reste ... – Sephy
Oh désolé à ce sujet. Merci d'avoir aidé à résoudre mon problème. – User358218
