如何使用此日期格式化oracle查询？

Question

I tried various alterations to get the right query date format. Below is one of them. The below date is actually filled in by string substitution from a java program. I need to be able to interpret it and run the query. Currently the query fails with the below error:

[Error] Execution (48: 18): ORA-01841: (full) year must be between -4713 and +9999, and not be 0

SELECT 
 to_date('Mon Jan 01 12:00:00 EST 1990', 'yyyy/mm/dd HH:MI:SS')
 FROM
 duAL

Answer 1

You cant use to_date for timezone. try this.

SELECT 
TO_TIMESTAMP_TZ('MON JAN 01 12:00:00 EST 1990', 'DY MON DD HH24:MI:SS TZR YYYY')
FROM
duAL;

Answer 2

我试试，删除了周一和美国东部时间

SELECT to_date('Jan 01 12:00:00 1990', 'MON DD HH:MI:SS RRRR') FROM dual 

Answer 3

[ EDIT ] Fixed the error, use TO_TIMESTAMP_TZ it should work.

SELECT 
TO_TIMESTAMP_TZ('Mon Jan 01 12:00:00 EST 1990', 'DY MON dd HH:MI:SS TZR yyyy')
FROM
duAL
