1 Answer. Use this combination of to_char and to_date : select to_char (to_date('20150324','YYYYMMDD'), 'DD-Mon-YY') from dual; Your mistake was, that you used the wrong date pattern.

Finally, you can change the default DATE format of Oracle from "DD-MON-YY" to something you like by issuing the following command in sqlplus: alter session set NLS_DATE_FORMAT='<my_format>'; The change is only valid for the current sqlplus session.

You may also try this: select to_char(to_date('1970-01-01 00:00:00', 'yyyy-mm-dd hh24:mi:ss')+(end_date - start_date),'hh24:mi:ss') as run_time from some_table; It displays time in more human readable form, like: 00:01:34.

You may use PARSE() to create DATETIME object from culture-specific format and then convert it to required string: select convert(varchar(20), parse('02/15/2016' as datetime2 using 'en-US'), 20); 20 is CONVERT()'s specific code for ODBC's date style (YYYY-mm-dd).
