a enable constrain problem

Hi,
I am trying to figure out a way to validate data from a direct path load. For example, the primary key constrain, I have to disable it in order to use the direct load method, then when I try to enable it, I got error like this: ORA-02437: cannot validate (PRDMDEV.ERIN1_PK) - primary key violated

I know this failed because there are some deplicated entries in the table. My real question is is there a way to let the database "kick-out" the duplicated entries, and only keep the valid ones? I searched the web, someone suggested something like this:

SQL> alter table erin1 enable validate constraint erin1_pk EXCEPTIONS INTO erin1_exp;
alter table erin1 enable validate constraint erin1_pk EXCEPTIONS INTO erin1_exp
*
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1 ORA-00913: too many values

But it seems doesn't work. The erin1_exp is another table with same schema as erin1. Can someone tell me what is wrong with this alter table command?

Thanks in advance!
