Pour utiliser Sqlite avec une base de données, vous avez 2 possibilités :
Vous êtes déjà dans Sqlite, dans ce cas ouvrez le fichier de base de donnée, par exemple le fichier s’appelle bdd.db, pou ouvrir un fichier il faut indiquer le chemin complet. Dans l’exemple ci-dessous, on a déjà ouvert Sqlite dans le répertoire du fichier bdd.db.
sqlite> .open bdd.db
Vous n’êtes pas encore dans Sqlite:
sqlite bdd.db

Je me suis intéressé à ça pour comparer les schémas des tables en local et en production avant de déployer EasyUpload, un clone de WeTransfer développé à 95% par mes étudiants.
