Another nifty trick is to use external tables. Believe it or not, you can
even
specify /*+ parallel */ in those babies.

another table
If you load your data into a table with an enable foreign key, it will be
checked on the fly by SQL*Loader with the conventional path. In direct mode
it disables constraints, and I am unsure whether it checks them when
reenabling them (something which you can optionally get); any way it would
let you with the manual check to do. If your CSV file is not in the million
of rows or more range, I would go for SQL*Loader with the conventional path.
