Mysql server中有没有类似TIMESTAMPADD的功能?
Is there any function similar to TIMESTAMPADD in Mysql server?
推荐答案
在 Oracle 中,如果你想要一个 timestamp
作为结果,而不是 date
(a date
总是包含到秒的时间,所以你可能只想要一个 date
),你想添加一个 interval
到时间戳
.构造区间有多种方法——你可以使用区间文字
In Oracle, if you want a timestamp
as the result, rather than a date
(a date
always includes the time to the second, though, so you may just want a date
), you'd want to add an interval
to the timestamp
. There are various ways to construct an interval-- you can use an interval literal
select current_timestamp + interval '10' second
from dual
或者你可以使用 numtodsinterval
函数
or you could use the numtodsinterval
function
select current_timestamp + numToDSInterval( 10, 'second' )
from dual
