oracle - Sqlloader when clause to include null -


i trying load data table, data source has footer record want remove , null values want loaded

my control file has:

echo "when field1 <> 'footer'"

but discarding null records (all others working expected).

is there way include 'or' operator, or running 2 step load inside single control file e.g. step 1. process records except 'footer' step 2 - process null records.

you can try this...

load data infile ... table ... ... ... when some_column != 'footer' ... fields terminated ', '
