Eliminate Duplicates Using SQLLDR and/or .ctl file

[gilgantic]

Is there anyway of eliminating duplicate entries as the database loads data
using SQLLDR and/or .ctl (Control File)?

I use the following command line using SQLLDR and a control file to load my
data, but the sample.dat file has duplicate information. I would like to be
able to eliminate this, since I have know ability to manipulate the sample.dat.
${ORACLE_HOME}/bin/sqlldr $USERPW /home/sample/sample.ctl

############# sample.ctl ###############
OPTIONS (DIRECT=TRUE)
LOAD DATA
INFILE '/home/sample/sample.dat'
truncate
INTO TABLE SAMPLE
(
NAME position(01:32) char,
EMAIL position(33:65) char
)
############### ############### ##########

Thank You

Can you manipulate the SAMPLE table? I would create a unique constraint
on the field(s) you don't want duplicated. The duped records from the
sample.dat would then land in your badfile.
