如何在oracle时间戳中添加第二个

2021-11-27 00:00:00 sql oracle amazon-rds

如何在 Oracle 中添加带有时间戳值的秒数.我试过这个......

How can I add seconds with timestamp value in Oracle. I tried this ....

SELECT CURRENT_TIMESTAMP , CURRENT_TIMESTAMP+200 AS addedTime FROM dual

但是通过这个我得到了这个

But by this I am getting this

2018-06-04 19:03:01 => 2018-12-21 19:03:01(添加 200 后)

2018-06-04 19:03:01 => 2018-12-21 19:03:01 (after adding 200)

如您所见,日期正在添加,但我只想添加第二个...

As you can see date is getting added , but I want to add second only...

此 SQL 在 DB2 中正常运行,任何人都可以向我建议在 Oracle 中任何合适的替代方案.

This SQL running properly in DB2 , can any one suggest me any suitable alternative in Oracle.

推荐答案

你总是可以使用分数(for Oracle 1 = 1 day):

You could always use fraction(for Oracle 1 = 1 day):

SELECT CURRENT_TIMESTAMP ,
       CURRENT_TIMESTAMP + 200 *(1/24/60/60) AS addedTime 
FROM dual;
<=>
SELECT CURRENT_TIMESTAMP + 200/86400 FROM dual

DBFiddle 演示

或:

SELECT CURRENT_TIMESTAMP + INTERVAL '200' SECOND FROM dual
