1.查询update语句执行的时间节点 ；

select t.FIRST_LOAD_TIME, t.SQL_TEXT from v$sqlarea t where to_char(t.FIRST_LOAD_TIME) > '2023-03-19/17:00:00' order by t.FIRST_LOAD_TIME desc;

2. 开启表的行迁移

alter table test enable row movement;

3.回滚表数据到目标节点

flashback table test to timestamp to_timestamp('20230319 17:00:02','YYYYMMDD HH24:MI:SS');

4.查询回滚结果

```sql
SQL> select * from test;

COL1               ID
---------- ----------
col1                1
col2                2
col3                3
col4                4
