DUMP LOAD D'UNE BASE DE DONNÉES

-- Script de Dump et de load des données d'une base vers une autre 
-- Note : 
--	Les 2 bases doivent avoir la meme structure
--      si il existe des données dans la base de destination, elles seront supprimées
--      Les 2 bases doivent être installées sur le même moteur
--      le transfert des données passant par un dossier disque, ne pas oublier de le créer avant
--	il est conseillé de désactiver les contraintes d'intégrité avant de lancer le traitement
--
