我知道如何使用 DATEADD 将纪元时间戳转换为 SQL 服务器时间戳,但我对执行相反操作的函数感兴趣.
I know how to convert an epoch timestamp to a SQL server timestamp using DATEADD, but I am interested in a function that does the reverse of that.
您可以使用 DATEDIFF
函数来完成,如下所示:
You can do it using DATEDIFF
function like below :
select DATEDIFF(s, '1970-01-01 00:00:00', '2017-11-20 23:12:02.000') as EpochTimeStamp
输出:
EpochTimeStamp
--------------
1511219522
你已经知道我们怎样才能回到原来的日期:
You know already how can we get back the original date :
SELECT DATEADD(ss, 1511219522, '19700101') as OriginalDate
OriginalDate
-----------------------
2017-11-20 23:12:02.000
