Query regarding External tables

Question

DECLARE
FileIn UTL_FILE.FILE_TYPE;
v_sql VARCHAR2 (1000);
BEGIN
FileIn := UTL_FILE.FOPEN ('DIR_TEMP', 'test_file_out.txt', 'R');
IF UTL_FILE.IS_OPEN(FileIn) THEN
LOOP
BEGIN
UTL_FILE.GET_LINE (FileIn, v_sql);
dbms_output.put_line(v_sql);
EXCEPTION
WHEN NO_DATA_FOUND THEN
EXIT;
END;
END LOOP;
END IF;
UTL_FILE.FCLOSE (FileIn);
END;
above mentioned is the procedure to read from a flat file.
I would like to know the procedure to load flat file data into table using external tables:
i have tried using this code but it displays errors:
CREATE TABLE EXT_EMP
( EMPNO NUMBER(4), ENAME VARCHAR2(10), JOB VARCHAR2(9),
MGR NUMBER(4), HIREDATE DATE, SAL NUMBER(7,2), COMM NUMBER(7,2), DEPTNO NUMBER(2))
ORGANIZATION EXTERNAL (
TYPE ORACLE_LOADER
DEFAULT DIRECTORY DIR_TEMP
ACCESS PARAMETERS(
RECORDS DELIMETED BY newline
FIELDS TERMINATED BY ','
MISSING FIELD VALUES ARE NULL(COMM NUMBER(7,2))
LOCATION ('test_file_out.txt')
PARALLEL
REJECT LIMIT UNLIMITED;
db: Oracle 11g , OS: windows vista

Answer 1

the query works fine as table is created.
but:
select * from ext_emp;
o/p: no rows.
