如何在Oracle中将字符串转换为日期格式

Question

I have a file contains a string like 2011-03-14 11:57:42+08:00 and I need to store it in a column with DATE datatype. I use Oracle 11g.

I have tried TO_DATE function but it didn't work.

Can anyone help me?

thanks in advance

You have to use the function TO_TIMESTAMP_TZ to get the timezone properly parsed:

SELECT CAST(TO_TIMESTAMP_TZ('2011-03-14 11:57:42+08:00', 'YYYY-MM-DD HH24:MI:SS+TZH:TZM') AS DATE) AS my_date 
  FROM DUAL
 ;

(And as a side note to your example in the comment: no need for TO_CHAR , quoting was missing and format model MON (abbreviated month) was incorrect)
