Désinstallation de l’environnement de la clean room¶

Pour désinstaller complètement l’environnement de clean room de votre compte, vous devez utiliser le rôle ACCOUNTADMIN dans le compte Snowflake où l’application de clean room est installée. Cette opération supprimera l’environnement de clean room pour tous les utilisateurs de votre compte, qu’ils soient fournisseurs ou consommateurs de clean room.

Pour désinstaller l’environnement de clean room pour votre compte :

1. Supprimez toutes les salles blanches que vous avez créées en tant que fournisseur.

2. Désinstallez toutes les salles blanches que vous avez installées (rejointes) en tant que consommateur.

3. Exécutez les commandes de désinstallation suivantes.

   Chaque instruction SELECT CONCAT génère une ou plusieurs commandes SQL que vous devez exécuter dans une feuille de calcul Snowflake dans le compte où vous souhaitez supprimer l’environnement de la clean room.

   -- Drop created and installed (joined) clean rooms, if you have not done so.

       FROM listings WHERE "state" = 'PUBLISHED'
   ),
   drop_listings AS (
