insert unique records froms sql*loader

Hi,

I have a csv file something like this.

Quote:

---

1 Tony Newyork 23444
1 Tony Newyork 12343
2 Blake London 12332
2 Blake London 12344
2 Blake London 12344

---

Now using sql*loder, can i insert into a table only unique data.

Say 2 Blake London 12344 is repeated.
So i want only one record of this inside that table.

Can i control this from sql*loader while inserting into table

why do you care - ensur eyou have the correct keys on the database, then let sql loader fail on the records which are duplicate
