Hello,

I need a function that converts date_to_unixtime. I found a good select example in the post #4 by Mark Schrijver: http://jehiah.cz/archive/oracle-date-to-unix-timestamp

I modified it a little and tried to make a function out of this select. There is an error in the function, I can not figure it out. Please help.

<pre>

CREATE OR REPLACE FUNCTION CURRENT_UNIXTIME_UTC_SEC RETURN number IS

   xt number;
BEGIN
  SELECT d * (24*60*60) + h * (60*60) + (m * 60) + s as unix_time FROM (
SELECT to_number(rtrim(substr(dt, 2, instr(dt, ' ')-1))) d,

    to_number(substr(dt, instr(dt, ' ')+1, 2)) h,
    to_number(substr(dt, instr(dt, ':')+1, 2)) m,
    to_number(substr(dt, instr(dt, '.')-2, 2)) s,

    dt
FROM ( SELECT to_char(dt) dt
FROM (
SELECT (
    sys_extract_utc(current_timestamp) - TO_TIMESTAMP('01.01.1970','DD.MM.YYYY')) dt FROM dual

    ))) INTO xt;
RETURN xt;
EXCEPTION
WHEN OTHERS THEN
      raise_application_error(-20777,'An error encountered - '|| SQLCODE||' ERROR: '||SQLERRM);
END;
