You can use Sql*Loader (sqlldr) :
TEST@db102 SQL> create table test (a varchar2(30), b varchar2(30), c varchar2(30));
Table created.
TEST@db102 SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options
$ cat test.csv
aaa,bbb,ccc
ddd,eee,fff
111,222,333
$ cat test.ctl
load data
infile 'test.csv'
replace into table test
fields terminated by ','
(a char, b char, c char)
$ sqlldr test/test control=test.ctl
