/*
    Script de création des tables SQL Server pour la synchronisation Meta Lead Gen.

    IMPORTANT :
    Avant de lancer ce script, la base de données doit déjà exister.

    Étapes :
    1. Se connecter à SQL Server avec un outil comme Adminer, SSMS, Azure Data Studio ou DBeaver.
    2. Créer la base de données si elle n'existe pas encore :

       CREATE DATABASE MetaLeadDb;

    3. Se connecter ensuite à la base MetaLeadDb.
    4. Lancer ce script pour créer les tables :
       - leadgen_forms
       - lead_data
       - sync_logs

    Ce script ne crée pas la base de données.
    Il crée uniquement les tables nécessaires au projet.*/
