Course Introduction：Rollback is a database operation used to undo changes to the database. In an Oracle database, rollback can be performed by connecting to the database and starting a transaction. Execute a ROLLBACK statement to roll back changes in a transaction. Commit the transaction to permanently save the rollback operation (optional). Additionally, Oracle provides other rollback options such as SAVEPOINT rollback, single row rollback, and table rollback.

Course Introduction：The rollback operation in Oracle can undo the changes in uncommitted transactions and restore the database to the state before the transaction started. There are two methods of rollback: explicitly rolling back the current transaction using the ROLLBACK statement, or automatically rolling back the transaction when an error occurs through exception handling. 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.
