Common SCNFlashBack flash back statements

You can use the SCN_TO_TIMESTAMP (after 10 Gb) function to convert it back to timestamp: selectdbms_flashback.get_system_change_number, SCN_TO_TIME

You can use the SCN_TO_TIMESTAMP (after 10 Gb) function to convert it back to timestamp: select dbms_flashback.get_system_change_number, SCN_TO_TIME

You can use the SCN_TO_TIMESTAMP (10 Gb later) function to convert it back to timestamp:

Select dbms_flashback.get_system_change_number, SCN_TO_TIMESTAMP (dbms_flashback.get_system_change_number) from dual;

You can also use the timestamp_to_scn function to convert a timestamp to SCN:

Select timestamp_to_scn (SYSTIMESTAMP) as scn from dual;

If you want to convert the DATE type to the TIMESTAMP type, use the CAST function.

Select cast (sysdate as timestamp) from dual;

-- Restored to a few minutes ago
Select t. *, t. rowid from ar_mid_acap as of timestamp sysdate-5/1440 t;

-- Restore to a specific time point
Select *
From ar_mid_acap as of scn timestamp_to_scn (To_Date ('2017-4-25 ', 'yyyy-mm-dd hh24: mi: ss '));

-- Change information between two time points
Select v_id, va, versions_startscn, versions_endscn, versions_operation
From t_fb_test versions between scn 12372466 and 12372538
Order by 1;

-- Restore statement undo
Select xid, commit_scn, commit_timestamp, operation, undo_ SQL
From flashback_transaction_query q
Where q. xid in
(Select versions_xid
From t_fb_test versions between scn 23413946 and 23413959 );

-- Restore table
Flashback table goodsinfo1 to before drop;
