SQL Loading : Constant NULL clause [message #71710]

Hi,
What is the way to insert a default of NULL
into a NUMBER Columns?

The table is with fields a(varchar2), b(varchar2)
and c(NUMBER).

The following works:
-----------------------
(
a ,
b ,
c constant 0
)
-----------------------

whereas the following does not:
-----------------------
(
a ,
b ,
c constant NULL
)
-----------------------

How can I introduce a NULL automatically during
sql*loader?

TIA
Debby

Thanks Mahesh,
But I have already got the solution. I used the
following instead:
...
b,
c "NULL"
)
