to-date

I need to convert a string into a Date in oracle. The format of the string is like this: '08/11/1999 05:45:00 p.m.' But the last position can change p.m or a.m. I tried to do some like: to_date('08/11/1999 05:45:00 p.m.', 'dd/mm/yyyy hh:mi:ss a.m./p.m.') to_date('08/11/1999 05:45:00 p.m.', 'dd/mm/yyyy hh:mi:ss am/pm') But return me an error ORA-01855 : AM/A.M. or PM/P.M. required... any idea ? Try this: to_date ( '08/11/1999 05:45:00 p.m.' , 'dd/mm/yyyy hh:mi:ss a.m.' , 'nls_date_language=american' ) It seems that "a.m." and "p.m." rather than "am" and "pm" require nls_date_language to be set

I have string of date from xml file of such kind: '2010-09-09T22:33:44.OZ' I need to extract only date and time. I want to ignore symbol T and .OZ (time zone). Which mask I should use? Thanks in advance select TO_DATE('2010-09-09T22:33:44.OZ' ,'YYYY-MM-DD"T"HH24:MI:SS".OZ"') from dual; 9/09/2010 10:33:44 PM If the timezone information is needed: select to_timestamp_tz('2010-09-09T22:33:44.GMT','YYYY-MM-DD"T"HH24:MI:SS.TZR') from dual; 09-SEP-10 22.33.44.000000000 GMT But OZ isn't a recognised timezone abbreviation, so you'd need to do some pre-conversion of that to something that is. If you

I have a text field "presence_changed_at" with text values i.e. '2014/12/17 08:05:28 +0000 . I need to convert this into timestamp. In postgreSQL there is function TO_TIMESTAMP() , however in redshift this does not seem to be supported. I can get the date without time by TO_DATE("presence_changed_at",'YYYY/MM/DD HH24:MI:SS') which produces 2014-12-12 but i can't find any way to get TIMESTAMP format. Thanks in advance for solving this try convert function: convert(timestamp,presence_changed_at) It's surprisingly horrible to get a datetime from a unixtime in redshift without a subselect. However

I have to perform some inserts into an Oracle DB. I have some dates in the following format '23.12.2011 13:01:001' Following the documentation I wrote inserts to_date as follows: to_date('23.12.2011 13:01:01', 'DD.MM.YYYY HH24:MI:SS') which works properly. Now I have dates with milliseconds with the format '23.12.2011 13:01:001' I've tried the following: to_date('23.12.2011 13:01:001', 'DD.MM.YYYY HH24:MI:SSFF3') which is incorrect (delivers an error 01821. 00000 - "date format not recognized"). Which "String" should I use for this format with milliseconds? Thanks in advance! An Oracle DATE

I have a table of the structure: +---------+--------------+-----------------+---------------+-------+------+ | week_no | long_week_no | week_start_date | week_end_date | month | year | +---------+--------------+-----------------+---------------+-------+------+ | 1 | 1A | 01/01/2015 | 03/01/2015 | JAN | 2015 | | 1 | 1B | 04/01/2015 | 10/01/2015 | JAN | 2015 | | 2 | 2 | 11/01/2015 | 17/01/2015 | JAN | 2015 | | 3 | 3 | 18/01/2015 | 24/01/2015 | JAN | 2015 | | .. | .. | .. | .. | .. | .. | | 51 | 51 | 14/12/2014 | 20/12/2015 | DEC | 2014 | +---------+--------------+-----------------+--------------

I want to convert the follow string to date: 2004-09-30 23:53:48,140000000 I tried: to_date('#', 'YYYY-MM-DD HH24:MI:SS,FF9') But PL/SQL keep throwing this error: ORA-01821: date format not recognized. FF9 is incorrect for Oracle, any suggestion? Oracle stores only the fractions up to second in a DATE field. Use TIMESTAMP instead: SELECT TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') FROM dual , possibly casting it to a DATE then: SELECT CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE) FROM dual I don't think you can use
