What is a rollback in databases?
A rollback in databases is a process that restores the database to a previous state, undoing changes.
When would I need to use a rollback?
You would use a rollback if there was an error during a transaction or if you need to revert to a stable state.
Can you give me an example of when a rollback is necessary?
Sure! If a financial transaction fails midway, a rollback can revert the database to its state before the transaction.
Are there any risks associated with using rollbacks?
Yes, excessive rollbacks can lead to data loss or inconsistency if not managed properly.
