- How to roll back in oracle
- The rollback operation in Oracle can undo the changes in uncommitted transactions and restore the database to the state before the transaction started.

Rollback can only undo changes in an uncommitted transaction, and the best practice is to use exception handling to handle errors in the transaction to ensure that the transaction is rolled back correctly when an error occurs.
