To manipulate Oracle flashback table data, these steps can be used:<\/p>\n

    \n
  1. Ensure that the flashback table feature is enabled in the database. This can be checked using the following command:<\/li>\n
  2. What is the status of flashback for this database?<\/li>\n
  3. If the return value is YES, it means that the flashback table feature has been enabled. If the return value is NO, the following command needs to be used to enable it:<\/li>\n
  4. Turn on flashback for the database.<\/li>\n
  5. Recover data from the flashback target table using flashback query statements. You can use the following command:<\/li>\n
  6. Restore the table “table_name” to a previous point in time specified by the timestamp_value.<\/li>\n
  7. table_name is the name of the table where data will be restored, while timestamp_value is the timestamp of the point in time to restore to.<\/li>\n
  8. For example, to restore the table employees to its state one hour ago, you can use the following command:<\/li>\n
  9. Roll back the table employees to its state one hour ago.<\/li>\n
  10. Please note that flashback table operation can only recover table data and cannot recover changes to the table structure. If the table structure also needs to be restored, you can use database backup and restore methods.<\/li>\n
  11. To view the available flashback time range, you can use the following command:<\/li>\n
  12. Retrieve all records from the table ‘dba_flashback_archive_tables’.<\/li>\n
  13. This will return tables in the database that have Flashback enabled, along with their Flashback time range.<\/li>\n<\/ol>\n

    It is important to note that the flashback table feature requires the database to have a flashback area enabled to store historical data. If the flashback area doesn’t have enough space, the flashback table operation may not be successful. You can use the following command to check the space situation of the flashback area:<\/p>\n

    SELECT<\/span> *<\/span> FROM<\/span> v$flash_recovery_area_usage;\r\n<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
