What is the difference between commit and rollback in databases?

Can you explain the difference between commit and rollback in databases?

Sure! In databases, a 'commit' saves all changes made during a transaction, while a 'rollback' undoes those changes.

When would I use rollback instead of commit?

You would use rollback if you encounter an error or if you decide not to proceed with the changes made during a transaction.

Can you give me an example of when to use each?

Absolutely! If you successfully update a record and want to keep that change, you would commit. If you realize there's an error in the data before committing, you would rollback.

What happens if I forget to commit after making changes?

If you forget to commit, the changes will not be saved, and they will be lost once the session ends or the transaction is rolled back.
