Oracle Transaction Management Guide
Transaction management in Oracle databases can be achieved by following these steps:
- Start Transaction: Before executing any operation that requires transaction management, begin a new transaction using the BEGIN TRANSACTION or START TRANSACTION statement.
- Execute SQL statements: Perform SQL operations inside a transaction that require transaction management, such as INSERT, UPDATE, DELETE, etc.
- Submit transaction: If all SQL statements have been executed successfully and you wish to save the results, use the COMMIT statement to submit the transaction. After the transaction is submitted, the database will permanently save all operations.
- Rollback transaction: In case of an error occurring during a transaction or if the need arises to undo previously executed operations, the ROLLBACK statement can be used to rollback the transaction. Once the transaction is rolled back, previously executed operations will be canceled, restoring the database to its state prior to the start of the transaction.
- End transaction: Use END TRANSACTION or simply END to finish a transaction after committing or rolling back.
By following the aforementioned steps, transaction management can be conducted in Oracle database to ensure the consistency and integrity of database operations.
