External tables are far easier to use... e.g.
I have a file on my server in a folder c:\mydata called test.txt which is a comma seperated file...
1,"Fred",200
2,"Bob",300
3,"Jim",50As sys user:
CREATE OR REPLACE DIRECTORY TEST_DIR AS "c:\mydata";
GRANT READ, WRITE ON DIRECTORY TEST_DIR TO myuser;Note: creates a directory object, pointing to a directory on the server and must exist on the server (it doesn't create the physical directory).
As myuser:
SQL> CREATE TABLE ext_test
  2    (id      NUMBER,
  3     empname VARCHAR2(20),
  4     rate    NUMBER)
  5  ORGANIZATION EXTERNAL
  6    (TYPE ORACLE_LOADER
  7     DEFAULT DIRECTORY TEST_DIR
  8     ACCESS PARAMETERS
  9       (RECORDS DELIMITED BY NEWLINE
10        FIELDS TERMINATED BY ","
11        OPTIONALLY ENCLOSED BY '"'
12        (id,
13         empname,
14         rate
15        )
16       )
17     LOCATION ('test.txt')
18    );
Table created.
SQL> select * from ext_test;
        ID EMPNAME                    RATE
         1 Fred                        200
         2 Bob                         300
         3 Jim                          50
