When enabled, the flashback feature helps us recover data loss, corrupted data, or logical errors easily. In the following scenarios, we can use flashback with PITR (Point-in-Time Recovery) to recover data:

• Dropped tables

• Truncated tables

• Massive changes by inserts / updates / deletes

• Logical errors

2. After restoring the database, perform the until time recovery.

3. Open the database with resetlogs.

4. Export the table from the restored database and import it into the production database.

If you are using flashback, you can use it to recover the table. However, if there is no standby database, this will be a disadvantage because we'll need to...
