Answer / somnath pain

I suppose u r working with informatica.
So here u can import the source and after the source use a
expression transformation.
use a sq generator set start val to 1.
connect the nextval port to expession transformation.
apply a filter and set filter condition as nextval=1 connect
the filter o/p to target.
u will get the desired row.

regards,
Somnath
