Usage notes

  • Latency for the view may be up to 120 minutes (2 hours).
  • The view only displays objects for which the current role for the session has been granted access privileges.

  • The LAST_ALTERED column is updated when the following operations are performed on an object:

    • DDL operations.
    • DML operations (for tables only). This column is updated even when no rows are affected by the DML statement.
    • Background maintenance operations on metadata performed by Snowflake.
