Answer / pr@$@d
What Nagaraju suggest is right. But instead of creating
temp and then moving those to staging table.
Directrly load the data into staging table and write the
query to eliminate the duplicate rows.
It reduces the one step.

Answer / nagaraju chittamsetty
There is one way to avoid duplicate rows
First transfer the data into temp table by using control
file,this is only temp table.
Second create orginal stagging table then write a query to
eliminate the duplicate rows by taking the rowid.

Answer / srinivas.r
Yes,directly we can't handle the duplicate rows from the
SQLLOQDER, for that first we move the data into temp table
from flatfile.After that create the Staging talbe then make
validations before moving into staging table.

Answer / balaji venkiteela
create an unique index on staging table.
then run the loder program.It autometically omits the
duplicate records,we can find those records in bad file.
