Which of the following tables can retain data even after a session ends?

  1. Temporary Tables

  2. Transient Tables

  3. Permanent Tables

  4. Temporary and Transient Tables

The correct answer is: Permanent Tables

Permanent tables are designed to retain data indefinitely, even after a user session ends or the Snowflake account is restarted. They ensure that all data stored within them is persistent and can be accessed at any time, regardless of session status. This makes them suitable for storing essential business data or historical records that need to be kept over a long duration. On the other hand, temporary tables are session-based and are automatically dropped at the end of the user session. Transient tables, although they are not as durable as permanent tables, can retain data for a longer period, but they do not survive after a session ends in the same way that permanent tables do. Therefore, only permanent tables provide the required data retention capability beyond the session’s lifetime.
