  查詢20分鐘前的資料 SELECT * FROM TableName AS OF TIMESTAMP SYSDATE - 20/1440; 查詢指定時間前的資料 SELECT * FROM TableName AS OF TIMESTAMP TO_TIMESTAMP('2020-01-01 12:10:10','YYYY-MM-DD HH24:MI:SS'); 查到後就可以把該紀錄插入表中 INSERT INTO TableName SELECT * FROM TableName AS OF TIMESTAMP SYSDATE - 20/1440 WHERE ID = '123' COMMIT; ps.1440代表一天有1440分鐘 By Hao★
