Deinstallation der Clean Room-Umgebung¶

Um die Clean Room-Umgebung vollständig von Ihrem Konto zu deinstallieren, müssen Sie die Rolle ACCOUNTADMIN in dem Snowflake-Konto verwenden, in dem die Clean Room-Anwendung installiert ist. Dadurch wird die Clean Room-Umgebung für alle Benutzer in Ihrem Konto gelöscht, sowohl für Clean Room-Anbieter als auch für -Verbraucher.

So deinstallieren Sie die Clean Room-Umgebung für Ihr Konto:

1. Löschen Sie alle Reinräume, die Sie als Anbieter erstellt haben.

2. Deinstallieren Sie alle Reinräume, die Sie als Verbraucher installiert (verknüpft) haben.

3. Führen Sie die folgenden Deinstallationsbefehle aus.

   Jede SELECT CONCAT-Anweisung erzeugt einen oder mehrere SQL-Befehle, die Sie in einem Snowflake-Arbeitsblatt in dem Konto ausführen sollten, in dem Sie die Clean Room-Umgebung entfernen möchten.

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

   ),
   alter_n_drop_listings AS (
       SELECT 'ALTER LISTING ' || "name" || ' UNPUBLISH;DROP LISTING ' || "name" || ';'
       FROM listings WHERE "state" = 'PUBLISHED'
   ),
   drop_listings AS (
       SELECT 'DROP LISTING ' || "name" || ';'
       FROM listings WHERE "state" = 'UNPUBLISHED'

       OR "name" LIKE 'SAMOOHA_CLEANROOM_%'
       OR "name" = 'SAMOOHA_BY_SNOWFLAKE_LOCAL_DB'
       OR "name" LIKE 'SAMOOHA_INTERNAL_GOVERNANCE_%'
