);

Answer 1

Here's an example which, actually, works. See if it helps.
My CSV file:
HR,Croatia,385
SLO,Slovenia,386
Create external table - don't forget to
create directory (as Oracle object, using SYS account)
grant read (and write?) privileges on that directory to user who will be using it
.
SQL> create table emp_load
2 (country_id varchar2(5),
3 country_name varchar2(50),
4 region_id varchar2(5)
5 )
6 organization external
7 (type oracle_loader
8 default directory ext_dir
9 access parameters
10 (records delimited by newline
11 fields terminated by ','
12 (country_id char(5),
13 country_name char(50),
14 region_id char(5)
15 )
16 )
17 location ('externalfile1.txt')
18 )
19 reject limit unlimited;
Table created.
