What happens to additional changes made to the original table after cloning?

• A. They apply to the cloned table
• B. They do not affect the cloned table
• C. They may partially apply
• D. They create a new independent table

Answer: (B)

When a table is cloned in a database context, it creates an exact copy of the original table at the moment of cloning. This includes all the data and structure but does not create a live link to the original table. Therefore, any subsequent changes made to the original table—such as adding or removing rows, altering columns, or changing constraints—do not propagate or affect the cloned table in any way. The cloned table remains a static snapshot frozen at the time of the cloning process, ensuring that the data in the cloned table remains consistent with its state at the time of creation. This concept is crucial in data management as it allows for experimentation and backup without risking the integrity of the original dataset. Understanding this principle helps in effectively utilizing features like cloning in database operations, ensuring that users can manipulate one dataset without unintended consequences to another.
