oracle systimestamp (sysdate) 到毫秒
您能否提供存储函数的实现以获取当前 systimestamp
以毫秒为单位.
我可以使用的东西
从dual中选择current_time_ms;
并获取当前时间与 UTC 1970 年 1 月 1 日午夜之间的差值(以毫秒为单位).
谢谢.
解决方案- 数据库时区不可知
- 以毫秒为单位
- 在 XE 中工作
Could you provide implementation of stored function to get current systimestamp
as milliseconds.
Something I can use like
select current_time_ms from dual;
and get the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC.
Thanks.
解决方案- DB timezone agnostic
- with milliseconds
- works in XE
function current_time_ms return number is out_result number; begin select extract(day from(sys_extract_utc(systimestamp) - to_timestamp('1970-01-01', 'YYYY-MM-DD'))) * 86400000 + to_number(to_char(sys_extract_utc(systimestamp), 'SSSSSFF3')) into out_result from dual; return out_result; end current_time_ms;
