Generated columns can be of two types: &#8216;virtual&#8217;, which do not take up disk space and are calculated at query time, and &#8216;stored&#8217;, which do take up space and are calculated at the time of inserting or updating data. This functionality allows developers and database administrators to simplify query logic, improve performance, and maintain data integrity.
