Stale data despite successful execution suggests caching or privilege issues. Suspending and resuming the warehouse (C) clears potential caches. Secure views (D) might require specific privileges if the user running the notebook lacks access to the underlying data at the time the view was created, or may be based on data at a specific time travel point. Refreshing the session (A) or rebuilding the view (E) may not always guarantee a refresh of cached results. Dropping and recreating a view (B) is a drastic measure and should be considered only if other options fail.
