2.Thinking 2 精确到毫秒 TO_TIMESTAMP() 实时计算日期函数TO_TIMESTAMP使用链接 既然to_date函数只能精确到秒,那么,我们使用Oracle的另一个可以精确到毫秒的函数to_timestamp 2019-06-06 14:13:00 --2019-06-06 14:13:00.000000000 select to_timestamp('2019-06-06 14:13:00', 'YYYY-M...
SQL> select distinct timestamp from v$logmnr_contents; TIMESTAMP --- 2003-09-21 09:40:02 2003-09-21 09:42:39 这里需要注意的是,因为我之前已经设置NLS_DATE_FORMAT环境变量,所以上面的日期可以直接按这个格式写就行了,如果你没有设,则需要使用to_date函数来转换一下。 SQL> !env grep NLS NLS_LAN...

PostgreSQL , Oracle , 兼容性 , timestamp , interval , 时间相减 , numeric 背景 Oracle 时间相减,得到的是一个浮点值N,代表N天。 PostgreSQL 时间相减,得到的是一个时间间隔类型,但是可以转换为一个浮点值。 Oracle 例子 SQL>selectsysdate - to_date('2017-01-01','yyyy-mm-dd')fromdual; ...
在dbms_job这个package中还有其他的过程:broken、change、interval、isubmit、next_date、remove、run、submit、user_export、what; 大致介绍下这些过程: 1、broken()过程更新一个已提交的工作的状态,典型地是用来把一个已破工作标记为未破工作。这个过程有三个参数:job、broken与next_date。

2、执行表记录恢复 一般先根据时间进行查询,查询语句模式为select * from tb as of timestamp to_timestamp(time,'yyyy-mm-dd hh24:mi:ss'); tb指表名称,time指某个时间点 如select * from scott.test as of timestamp to_timestamp('2009-12-11 20:53:57','yyyy-mm-dd hh24:mi:ss'); 若有数...
As mentioned above, the 11.1 drivers by default convert SQL DATE toTimestampwhen reading from the database. This always was the right thing to do and the change in 9i was a mistake. The 11.1 drivers have reverted to the correct behavior. Even if you didn't setV8Compatiblein your applicat...
8i (and older) databases did not support the TIMESTAMP type. Setting not only caused SQL DATE to be mapped to Timestamp when read from the database, it also caused all to be converted to SQL DATE when written to the database. Since 8i is desupported, the 11.1 JDBC drivers do not ...
