Examine these statements: DESC emp INSERT INTO emp VALUES ( 101, 'John', 12000); 1 row created. SAVEPOINT after_insert; Savepoint created. UPDATE emp SET salary=16000 WHERE empno=101; 1 row updated…

The `ROLLBACK TO SAVEPOINT` command specifically undoes DML operations that occurred *after* the specified savepoint, not before it, while preserving DMLs up to the savepoint.

Assuming the initial `ROLLBACK TO SAVEPOINT after_update` does not invalidate subsequent savepoints, the final `ROLLBACK TO SAVEPOINT after_delete` command would successfully execute. It effectively undoes the `INSERT INTO emp VALUES (102, 'Emma', 12000)` and restores the table to the state it was in immediately after the original `DELETE FROM emp WHERE empno=101` and `SAVEPOINT after_delete` commands, which means the `emp` table would be empty.

Standard Oracle behavior dictates that `ROLLBACK TO SAVEPOINT after_update` would discard the `after_delete` savepoint, causing the subsequent `ROLLBACK TO SAVEPOINT after_delete` to fail with an error; however, the provided correct answer implies this standard behavior is not followed in this context.

If the `ROLLBACK TO SAVEPOINT after_delete` command successfully executes, it would indeed back out the `INSERT 102` DML operation and potentially other changes, therefore it would not result in no DMLs being backed out.
