Today accidentally deleted a data server later found the above very simple record it
SELECT * FROM 表 AS OF TIMESTAMP TO_TIMESTAMP('2019-05-13 09:00:00','yyyy-MM-dd hh24:mi:ss') where childname = '言之有李';Table refers to delete data tables where the time refers to the time before I remember that I did not delete probably around 9:06 deleted but can not remember exactly 9:00 directly write whole. This time will be displayed in this table you can also add the condition you want to locate the data in all the data back nine o'clock is not in it
