The following query:

select cdate from rprt where cdate <= TO_CHAR(sysdate, 'YYYY/MM/DD-HH24-MI-SS-SSSSS') and ryg='R' and cnum='C002';

return: 2013/04/27-10:06:26:794 as stored in the table.

I want to get the date only as : 27-04-2013 and get the number of days between the resul tdate and sysdate.

Use the function cast() to convert from timestamp to date 

select to_char(cast(sysdate as date),'DD-MM-YYYY') from dual;
