INSERT:
插入:
insert into myTable (col1) VALUES (to_char(systimestamp, 'dd-mon-yyyy hh.mi.ss.ff4 AM') );
SELECT:
选择:
select to_timestamp(col1, 'dd-mon-yyyy hh.mi.ss.ff4 AM') from myTable ;
But it is much better to store the data directly as a timestamp. Then you can compare the values ??or modify them directly.
但是将数据直接存储为时间戳要好得多。然后你可以比较这些值??或者直接修改它们。
create table myTable1( col1 timestamp default systimestamp);
