2、from_tz()将时间戳和时区转换成具有时区值的时间戳 select current_timestamp,from_tz(current_timestamp,'Asia/Shanghia') from dual; //因为current_timestamp本身就带有时区,该语句会出现 expected TIMESTAMP got TIMESTAMP WITH TIME ZONE 1. 第一个参数就是不带时区的时间戳,如果带时区就会出错 select ...
5、current_date、current_timestamp、localtimestamp、sessiontimezone、dbtimezone函数 current_date:9i新增函数,返回当前会话时区所对应的日期时间(date型) current_timestamp:以 timestamp with time zone 数据类型返回当前会话时区所对应的日期时间。 localtimestamp:返回当前会话时区的日期时间 sessiontimezone:返回会...
SELECT sysdate,systimestamp FROM dual 注意,to_char函数支持date和timestamp,但是trunc却不支持TIMESTAMP数据类型。 SELECT sysdate,systimestamp,to_char(systimestamp,'yyyymmdd hh24:mi:ssxff3') FROM dual 当你直接相减的话,看看会发生什么。结果将更容易理解, select systimestamp-systimestamp from dual ...
TIMESTAMPWITHTIMEZONEis a variant ofTIMESTAMPthat includes atime zone region name or atime zone offset in its value. The time zone offset is the difference (in hours and minutes) between local time and UTC (Coordinated Universal Time—formerly Greenwich Mean Time). This data type is useful fo...
在Oracle 9i中,按照SQL 99标准,增加了时间间隔型数据INTERVAL YEAR TO MONTH 和 INTERVAL DAY TO SECOND,它们和其他几种数据类型一起使得对时间的处理更加准确。TIMESTAMP、TIMESTAMP WITH TIME ZONE和TIMESTAMP WITH LOCAL TIME ZONE等数据类型都把时间的表达精确到了若干分之一秒,而且后面两种还解决了地理位置造成...

--STORE IN:指定分区存储的表空间 (2.2)间隔分区创建限制 间隔分区是范围分区的扩展,其支持范围有限,在Oracle 11g中,间隔分区只能指定一个分区键列,并且数据类型必须为NUMBER或者DATE类型。因为TIMESTAMP数据类型是DATE类型的扩展,可在分区键中使用。总结来说,间隔分区只支持NUMBER和TIME类型。

For example, in Oracle the date-time format can be given as: TIMESTAMP ‘YYYY-MM-DD HH24:MI:SS.FFF’ Using this we can define the timestamp to be:‘2006-01-02 15:04:05.999’ Couchbase N1QLsupports fractional seconds similar to Oracle. This is seen when using the format:...
