What are the differences between rollback and commit in databases?

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

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

When would I use rollback instead of commit?

You would use rollback if you encounter an error during a transaction and want to revert to the previous state.

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

Certainly! After successfully transferring funds between accounts, you would use commit to finalize the transaction.

Are there any risks associated with using commit?

Yes, if you commit changes and then realize there was an error, those changes cannot be undone unless you have a backup.
