-- PTA - INSTALLATION PRODUCTION COMPLETE
-- Version applicative cible : V7.7
-- MySQL 8.0.16+
-- ============================================================================
-- Usage : installation sur une BASE VIDE.
--
-- Ce script contient :
--   * toutes les tables nécessaires à PTA V7.7 ;
--   * les clés étrangères, index et contraintes ;
--   * les vues de pilotage ;
--   * les procédures de contrôle / validation ;
--   * uniquement les référentiels techniques indispensables (postes et motifs).
--
-- Il ne contient AUCUN agent, lieu, planning, quota ou jeu de démonstration.
--
-- IMPORTANT - correction MySQL #1832 :
-- creneau_horaire.id_motif est créé directement en INT UNSIGNED NOT NULL,
-- AVANT la création de fk_creneau_motif. Aucun ALTER TABLE ... MODIFY id_motif
-- n'est donc nécessaire sur une installation neuve.
