format of date using to_date function - sql

Question

I have a query which use a date
I work with oracle
but I have a problem in format of date
when I run my query I have an error
this my query test:
select NUM_REQUEST,
from REQUEST_TEST
where REQUEST_DATE between TO_DATE('Thu Nov 07 00:00:00 CET 2013','MM/dd/yyyy hh:mm:ss a') and TO_DATE('Mon Dec 23 00:00:00 CET 2013','MM/dd/yyyy hh:mm:ss a'))
I have an error in foramt of date using to_date function
when I try with this query and I have a correct result
select NUM_REQUEST,
from REQUEST_TEST
where REQUEST_DATE between to_timestamp_tz('Thu Nov 07 00:00:00 CET 2013','Dy Mon dd hh24:mi:ss TZR yyyy') and to_timestamp_tz('Mon Dec 23 00:00:00 CET 2013','Dy Mon dd hh24:mi:ss TZR yyyy'))
but when I test in my application with :
String sqlQuery = "select NUM_REQUEST, from REQUEST_TEST" +
" where REQUEST_DATE between to_timestamp_tz('Thu Nov 07 00:00:00 CET 2013','Dy Mon dd hh24:mi:ss TZR yyyy') and to_timestamp_tz('Mon Dec 23 00:00:00 CET 2013','Dy Mon dd hh24:mi:ss TZR yyyy')) ";
Query query = this.getSession().createSQLQuery(sqlQuery);
I have this error :
ORA-01846: ce n'est pas un jour de semaine valide
org.hibernate.exception.DataException: could not execute query
I have for example in my column REQUEST_DATE this data 29-NOV-13 and when I edit this column I have this format for example : friday, 29 Novembre 2013 00:00:00 o'clock CET

Answer 1

As others have said, your date format must match your date string. Have a look at Oracle Datetime Format Elements for all possible elements.
Also, since there is a timezone in your string you need to cast it to timestamp datatype and not date. So, you need to use TO_TIMESTAMP_TZ function.
So, to answer you question it should be something like this.
to_timestamp_tz('Thu Nov 07 00:00:00 CET 2013','Dy Mon dd hh24:mi:ss TZR yyyy')
Looks like your language setting is french. So you need to supply the month/day accordingly.
to_timestamp_tz('Jeu. Nov. 07 00:00:00 CET 2013','Dy Mon dd hh24:mi:ss TZR yyyy')
or you should explicitly change the language to English, which you can do in the function call itself.
to_timestamp_tz('Thu Nov 07 00:00:00 CET 2013',
'Dy Mon dd hh24:mi:ss TZR yyyy',
'nls_date_language = ENGLISH')

Answer 2

Probably you need this. And I believe you get this date format from UNIX.
You can also try formatting the date from Unix if so.
select to_timestamp_tz('Thu Nov 07 00:00:00 EDT 2013','Dy Mon DD HH24:MI:SS TZD YYYY') from dual;

Answer 3

The closest one I can think of would be:
select NUM_REQUEST,
from REQUEST_TEST
where REQUEST_DATE Between TO_TIMESTAMP_TZ('Thu Nov 07 00:00:00 CET 2013','DY MON DD HH24:MI:SS TZR YYYY' ) And TO_TIMESTAMP_TZ('Mon Dec 23 00:00:00 CET 2013','DY MON DD HH24:MI:SS TZR YYYY')
Be careful with the month abbreviations, as they depend on your locale language settings. For example, December is Dec in English but Dic in Spanish.
Update: your problem with ORA-01846 is related as well to your locale language settings. You need to use the abbreviation corresponding to your language. For example, I guess that for French the abbreviation for Friday (Vendredi in French) would be Ven.
