Snowflake Updated COF-C02 Exam Questions and Answers by lorelai

The correct function to find the query ID of the second query executed in the current session is SELECT LAST_QUERY_ID(-2). The LAST_QUERY_ID function returns the query ID for the most recent query executed in the session when called with no arguments. When used with an argument, it can retrieve the ID of previous queries within the same session, where -2 would reference the second most recent query executed.

References:

There's a clarification needed here; Snowflake's documentation indicates LAST_QUERY_ID() function does not accept arguments. It returns the ID of the last query executed in the session. To find the query ID of the second last executed query, users typically need to track query IDs manually or use session history views.

In Snowflake, cloning is available for certain types of objects, allowing quick duplication without copying data:

Schemas: These can be cloned, enabling users to replicate entire schema structures, including tables and views, for development or testing.

Internal named stages: These stages, used to store data files within Snowflake, can also be cloned, preserving configurations for data loading.

Users and external objects (like external stages or tables) cannot be cloned due to their dependency on external data and configurations outside Snowflake.
