To avoid formatting the date values in a particular format and then parsing it, I would like to convert date time to a number for my application.

The build-in conversion function does not support this.

Thanks,

Naresh

just date:

SQL> select to_char(sysdate,'ddmmyyyyhhmiss') from dual;

TO_CHAR(SYSDAT
--------------
22042004023944

date and time:

SQL> select to_char(sysdate,'ddmmyyyyhhmiss') from dual;

TO_CHAR(SYSDAT
--------------
22042004024100

You can TO_NUMBER these selects:

SQL> set numformat 99999999999999
SQL> select to_number(to_char(sysdate,'ddmmyyyyhhmiss'), 99999999999999) from dual;

TO_NUMBER(TO_CHAR(SYSDATE,'DDMMYYYYHHMISS'),99999999999999)
-----------------------------------------------------------
