How can I view drop records in Oracle?

To view the DROP records in an Oracle database, you can use the following method:

1. Flashback query: Oracle provides the functionality of Flashback query, which allows rolling back the state of database objects to a previous point in time. One can use the following statement to query for DROP records.
2. Retrieve the operation, object name, original name, and timestamp from the recycle bin table.
3. This will return the operation type (such as DROP), object name, original name, and deletion timestamp of the deleted object.
4. Utilizing log files: Oracle’s archive log files record all operations in the database, including DROP operations. You can use the following statement to query DROP records.
5. Retrieve the username, operating system username, session information, SQL text, and timestamp from the v$logmnr_contents table where the operation is ‘DROP’.
6. This will return the username, operating system username, session information, SQL statement, and timestamp of the DROP operation.
7. Utilize the auditing feature: If the auditing feature of the Oracle database has been enabled, you can query the audit logs to view DROP records. You can use the following statement to query DROP records:
8. Show the username, operating system username, terminal, action name, and timestamp for all entries in the database audit trail where the action is “DROP”.
9. This will return the username who performed the DROP operation, the operating system username, terminal information, operation name, and the timestamp of the operation.

Please note that the above method may require appropriate permissions to query DROP records.
