and the destination table is :
ID,
NAME,
Hire_date,
Job
how can i put the 1 in the ID , adam in the name and so on?
I need help urgent please

perhaps its easier to directly read the file using CLIENT_TEXTIO line by line instead of first transfering it into the database and then extracting it from there again.
Code example for CLIENT_TEXTIO (not tested):
DECLARE
  tf CLIENT_TEXT_IO.FILE_TYPE;
  vcBuffer VARCHAR2(32000);
  nId NUMBER;
  vcName VARCHAR2(4000);
  dtHiredate DATE;
  vcJob VARCHAR2(4000);
  FUNCTION FK_SPLIT(io_vcText IN OUT VARCHAR2)
  RETURN VARCHAR2 IS 
    vcReturn VARCHAR2(4000);
  BEGIN
    IF INSTR(io_vcText, ',')>0 THEN
      vcReturn:=SUBSTR(io_vcText, 1, INSTR(io_vcText, ',')-1);
      io_vcText:=SUBSTR(io_vcText, INSTR(io_vcText, ',')+1);
    ELSE
      vcReturn:=io_vcText;
      io_vcText:=NULL;
    END IF;
    RETURN vcReturn;
  END;
BEGIN
  tf:=CLIENT_TEXT_IO.FOPEN('filename', 'r');
  LOOP
    BEGIN
      -- read data line by line
      CLIENT_TEXT_IO.GET_LINE(tf, vcBuffer);
      -- split buffer into vars
      nId:=TO_NUMBER(FK_SPLIT(vcBuffer));
      vcName:=FK_SPLIT(vcBuffer);
      dtHireDate:=TO_DATE(FK_SPLIT(vcBuffer), 'dd/mm/yyyy');
      vcJob:=FK_SPLIT(vcBuffer);
      INSERT INTO DEST_TABLE (
        ID,
        NAME,
        HIRE_DATE,
        JOB
      ) VALUES (
        nId,
        vcName,
        dtHireDate,
        vcJob
    EXCEPTION
      WHEN NO_DATA_FOUND THEN
        EXIT;
  END LOOP;
  CLIENT_TEXT_IO.FCLOSE(tf);
END;(not tested)
If your importing large files it might be better to upload the file to the oas using WEBUTIL_FILE.CLIENT_TO_AS and then use TEXT_IO instead of CLIENT_TEXT_IO.
