How to rollback a delete operation in Oracle after it has been executed?
In Oracle, once a DELETE statement has been executed and changes have been committed, it is not possible to directly undo the commit. However, you can use a Rollback to revert the previous changes. A Rollback will restore the database to the state it was in at the last commit point, effectively undoing the results of the DELETE operation.
To cancel the previous submission and roll back the DELETE operation, you can follow these steps:
- Undo the changes;
Please note that rolling back will undo all uncommitted changes, not just the result of DELETE operations. This means that after rolling back, any INSERT, UPDATE, or other operations that were previously executed will also be undone.
To prevent accidental submissions, you can start a transaction before carrying out a DELETE operation, and only commit after confirming the results are correct. If unsure of the outcome of the DELETE operation, conducting a SELECT statement to review the data to be deleted can ensure the operation is correct.
