Append or prefix ?

Prefix:
SQL> select to_char(trunc(sysdate), 'DD-MON-YYYY HH:MI:SS AM') from dual;

TO_CHAR(TRUNC(SYSDATE),
-----------------------
30-DEC-2008 12:00:00 AM


Append:
SQL> select to_char(trunc(sysdate), 'HH:MI:SS AM DD-MON-YYYY') from dual;

TO_CHAR(TRUNC(SYSDATE),
-----------------------
12:00:00 AM 30-DEC-2008

Check TO_CHAR (datetime) and TRUNC (date).

'dd-MON-YYYY HH24:MI:SS') FROM sys.dual

You shall realize the difference between VARCHAR2 and DATE data type and its representation in result set.
VARCHAR2 is string, so its value is directly displayed.
DATE is in special format; so before displaying it, it has to be converted into string. Implicitely, NLS_DATE_FORMAT parameter is used.
If you want to only display the DATE column, convert it to string. However use DATE data type when processing it further (in subquery, PL/SQL, ...).

Also, Danish's code is too complicated, it would be sufficient to use only
SELECT TO_CHAR(sysdate,'dd-MON-YYYY') || '00:00:00 ' FROM SYS.DUAL;

But I would prefer ebrian's solution.

So I assume you simply copied the query that was already suggested above ??
