Oracle convert RAW to date format

问题

I have a RAW field in my Oracle database that represents the date of user registered in system.

The value is something like 24E2321A0000000000 However I need convert the value to the date it represents (etc 2008-12-25 15:04:31).

I tried with totimestamp (see this sqlfiddle) but that didn't work.

回答1:

Maybe this will help:

SELECT utl_raw.cast_to_binary_integer('24E2321A0000000000') raw_to_int
FROM dual
/

Output is 36. I'm not sure if you need days or hours. Next example is about adding 36 hours to SYSDATE:

-- SYSDATE + 36/24 --
SELECT SYSDATE+(utl_raw.cast_to_binary_integer('24E2321A0000000000')/24) my_date
FROM dual
/

MY_DATE
---------------------
12/13/2013 4:29:22 AM

please try one

declare
d date;
begin
   dbms_stats.convert_raw_value (hextoraw('7876070A010101'), d);
   dbms_output.put_line (d);
end;
